AZ-900 Microsoft Azure Fundamentals

Azure Fundamentals

Azure Fundamentals is an introductory series designed to help you understand the basics of Microsoft Azure, a cloud computing platform. It covers services like web hosting, virtual machines, remote storage, databases, and even advanced tech like AI and IoT.

You don’t need deep technical experience to get started, but some general IT knowledge can be helpful. The series includes interactive exercises, where you can practice using Azure in a free, temporary environment called a sandbox.

This course is great for beginners or those interested in cloud computing, especially if you want to earn Microsoft's official certification (AZ-900).

Introduction to cloud computing

Cloud computing provides IT services like storage, virtual machines, and networking over the internet, rather than relying on physical hardware. It also offers advanced services like AI, machine learning, and IoT.

Since its internet-based, cloud computing is not limited by physical infrastructure. If your business needs more IT resources quickly, you can scale up using the cloud without having to build new data centers.

Describe the shared responsibility model The shared responsibility model in cloud computing means that the cloud provider and the customer share responsibility for different aspects of cloud services.

• Cloud Provider's Responsibilities: They take care of the physical infrastructure, like the datacenter, network, power, and cooling.
• Customer's Responsibilities: You are responsible for your data, who has access to it, and the devices connected to the cloud.

For other areas, responsibility depends on the service type:

• IaaS (Infrastructure as a Service): You manage more, like the operating system and applications.
• SaaS (Software as a Service): The cloud provider handles most things, like software and updates.
• PaaS (Platform as a Service): Responsibilities are shared more evenly between you and the cloud provider.

In short, the cloud provider handles the infrastructure, and you handle the data and access. The exact balance of responsibilities depends on the service you're using.

Define cloud models

Cloud models define how cloud resources are deployed. The three main types are:

1. Private Cloud: This cloud is used by one company only, offering more control but also higher costs. It can be hosted on-site or by a third party in a dedicated datacenter.
2. Public Cloud: Built and maintained by a cloud provider, it's available to anyone who wants to use it. It's cost-effective and accessible to the general public.
3. Hybrid Cloud: A mix of private and public clouds, allowing companies to use both for different needs. For example, they can keep sensitive data in the private cloud and use the public cloud to handle extra demand.

Who can be cloud provider?

A cloud provider is a company or organization that offers cloud computing services like storage, virtual machines, databases, and networking over the internet. Some well-known cloud providers include:

1. Microsoft Azure
2. Amazon Web Services (AWS)
3. Google Cloud
4. IBM Cloud
5. Oracle Cloud
6. Alibaba Cloud

These providers maintain large data centers and offer a range of services that customers can use to build, store, and manage their applications and data in the cloud.

In a multi-cloud setup, you use services from multiple public cloud providers (like Azure, AWS, or Google Cloud) at the same time. This could be because you need specific features from different providers or you're transitioning between them. Managing resources and security across multiple clouds is part of this approach.

Azure Arc helps you manage your cloud environment, whether you're using Azure, a private cloud, a hybrid setup, or multiple cloud providers (multi-cloud).

Azure VMware Solution lets businesses that use VMware in their private cloud move those workloads to Azure, making it easy to scale and integrate with Azure’s services.

VMware what is this?

VMware is a company that provides virtualization technology, which allows you to create virtual machines (VMs). Virtual machines let you run multiple operating systems on a single physical server, optimizing resources and making IT management more flexible and cost-effective.

VMware’s software is widely used in data centers to create virtualized environments where businesses can run multiple applications and services efficiently. This technology is crucial for private cloud setups, enabling companies to manage servers, storage, and networking in a more flexible, scalable way.

For example, VMware products like vSphere and vCenter help manage and run virtual servers, making it easier to handle IT infrastructure without needing physical servers for each application.

Describe the consumption-based model

The consumption-based model in cloud computing means you only pay for the IT resources you use, like storage or virtual machines. There are no upfront costs or need to buy and maintain expensive infrastructure. If you need more resources, you can add them, and if you need less, you can scale back, only paying for what you actually use.

This model is part of operational expenditure (OpEx), where costs are ongoing, compared to capital expenditure (CapEx), which is a one-time investment like building a data center. The main advantage of this model is flexibility and efficiency: you can adjust resources based on demand and avoid paying for unused capacity.

Describe the benefits of high availability and scalability in the cloud

When building a cloud application, two key things to focus on are uptime (availability) and scalability (handling demand).

• High availability ensures your app or service is always available, even during disruptions. Cloud providers like Azure offer service-level agreements (SLAs) that guarantee availability.
• Scalability lets you adjust resources based on demand. You can add more resources when traffic increases and reduce them when demand drops, saving costs in the process.

There are two types of scaling:

1. Vertical scaling: Increasing or decreasing the power of a single resource, like adding more CPU or RAM to a virtual machine.
2. Horizontal scaling: Adding or removing multiple resources, like adding more virtual machines to handle more traffic, or reducing them when demand decreases.

This way, you ensure your app can handle varying traffic loads efficiently.

Describe the benefits of reliability and predictability in the cloud

Two key benefits of the cloud are reliability and predictability, which help you build stable and efficient solutions.

• Reliability means your system can recover from failures and keep working. Cloud providers like Azure have global regions, so even if one region fails, others keep running. This setup ensures that your applications can automatically shift to another region if needed, ensuring reliability.
• Predictability helps you plan for both performance and cost: Performance predictability ensures that your app performs well. Cloud features like autoscaling and load balancing automatically adjust resources to meet demand and keep things running smoothly. Cost predictability helps you forecast cloud spending. You can track usage in real-time, optimize resources, and use tools like the Total Cost of Ownership (TCO) or Pricing Calculator to estimate costs and plan ahead.

Describe the benefits of security and governance in the cloud

When using the cloud, whether for Infrastructure as a Service (IaaS) or Software as a Service (SaaS), there are features that support governance (rules and standards) and compliance (meeting regulations).

• Governance and Compliance: Cloud services provide templates to ensure all your resources meet company and legal standards. You can easily update resources to align with new standards. Cloud-based auditing helps identify any resources that aren’t compliant and offers ways to fix them. Automatic software updates also help maintain governance and security.
• Security Options: Depending on your needs, you can choose how much control you want over security: IaaS gives you control over physical resources and lets you manage the operating systems and software. Platform as a Service (PaaS) or SaaS handles updates and maintenance automatically, which is easier for users.

Cloud providers are also equipped to handle security threats, like distributed denial of service DDoS attacks, making your network safer.

By setting up strong governance from the start, you can ensure your cloud resources are secure and well-managed.

Describe the benefits of manageability in the cloud

Cloud computing offers great manageability options, which come in two forms: management of the cloud and management in the cloud.

Management of the Cloud

This involves managing your cloud resources, allowing you to:

• Automatically scale resources up or down based on demand.
• Use preconfigured templates to deploy resources without manual setup.
• Monitor the health of resources and automatically replace any that fail.
• Get automatic alerts about performance, so you can see how everything is running in real-time.

Management in the Cloud

This refers to how you manage your cloud environment and resources. You can do this through:

• A web portal
• Command line interface
• APIs (Application Programming Interfaces)
• PowerShell

These options make it easier to manage and control your cloud services efficiently.

IaaS

Infrastructure as a Service (IaaS) is a flexible cloud service that gives you maximum control over your cloud resources. Here’s how it works:

• What IaaS Provides: The cloud provider manages the hardware, network connectivity, and physical security. You rent this hardware and are responsible for everything else, such as: Installing and configuring operating systems Managing network settings Configuring databases and storage

Shared Responsibility Model

In IaaS, most of the responsibility falls on you:

• Cloud Provider: Manages physical infrastructure and internet access.
• You: Handle installation, configuration, updates, and security.

Common Scenarios for IaaS

1. Lift-and-Shift Migration: Move applications from your physical datacenter to IaaS without changing their architecture.
2. Testing and Development: Quickly create and manage development and test environments, allowing for easy setup and teardown as needed.

IaaS is ideal for businesses that need flexibility and control over their cloud resources.

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a cloud service that offers a balance between renting infrastructure (IaaS) and using fully deployed software (SaaS). Here’s what you need to know:

What PaaS Provides

• Cloud Provider's Responsibilities: Manages physical infrastructure, security, and internet connection. Maintains operating systems, middleware, development tools, and business intelligence services.
• Your Responsibilities: Focus on developing and deploying applications without worrying about licensing, patching, or maintaining the underlying infrastructure.

Shared Responsibility Model

In PaaS, responsibilities are shared:

• Cloud Provider: Handles infrastructure, operating systems, and development tools.
• You: May manage networking settings, application security, and connectivity depending on the setup.

Common Scenarios for PaaS

1. Development Framework: PaaS provides tools and frameworks that developers can use to build applications quickly, reducing coding effort.
2. Analytics and Business Intelligence: PaaS offers services to analyze data, helping organizations gain insights and improve decision-making.

PaaS is ideal for developers who want to create applications efficiently without the burden of managing infrastructure.

Describe Software as a Service

Software as a Service (SaaS) is a cloud service model where you rent fully developed applications. Here’s a quick overview:

What SaaS Offers

• Examples: Email services, financial software, and messaging applications.
• Ease of Use: SaaS is the easiest to set up and requires minimal technical knowledge.

Shared Responsibility Model

In SaaS, the responsibilities are divided as follows:

• User Responsibilities: Manage the data you input. Control the devices and users that access the application.
• Cloud Provider Responsibilities: Handle physical security, power, network connectivity, and application maintenance.

Common Scenarios for SaaS

1. Email and Messaging: Services like Gmail and Slack.
2. Business Productivity Applications: Tools like Microsoft Office 365 and Google Workspace.
3. Finance and Expense Tracking: Applications like QuickBooks and Expensify.

SaaS is ideal for users who need ready-to-use software without the hassle of managing the underlying infrastructure.

?

Describe Azure physical infrastructure

Azure Physical Infrastructure consists of:

1. Datacenters: Physical locations with power, cooling, and networking resources. Azure datacenters are grouped into: Regions: Geographical areas with multiple datacenters. Availability Zones: Physically separate datacenters within a region, offering redundancy and protection from failures.
2. Region Pairs: Two regions in the same geography, separated by at least 300 miles, that back up each other for resilience. Example pairs include West US-East US and Southeast Asia-East Asia.
3. Sovereign Regions: Isolated Azure instances for specific legal or compliance needs, like US Gov Virginia or China North.

These elements ensure high availability, resiliency, and disaster recovery in Azure's global cloud infrastructure.

Describe Azure management infrastructure

Azure’s management infrastructure includes resources, resource groups, subscriptions, and management groups. Here's a concise breakdown:

1. Azure Resources: Basic components (e.g., VMs, databases) you create or manage in Azure.
2. Resource Groups: Logical containers for organizing related resources. Deleting a resource group deletes all resources within it.
3. Subscriptions: Units for billing and access control. You can organize resource groups within subscriptions and create multiple subscriptions to separate environments, organizations, or billing needs.
4. Management Groups: A level above subscriptions, used to apply policies and manage access across multiple subscriptions. They allow large-scale governance and can be nested into a hierarchical structure.

This organization helps manage resources efficiently, control access, and organize billing across Azure services.

Exercise - Create an Azure resource

Task 1: Create a virtual machine

In this task, you’ll create a virtual machine using the Azure portal.

1. Sign in to the?Azure portal .
2. Select Create a resource > Compute > Virtual Machine > Create.
3. The Create a virtual machine pane opens to the basics tab.
4. Verify or enter the following values for each setting. If a setting isn’t specified, leave the default value.

Task 2: Verify resources created

Once the deployment is created, you can verify that Azure created not only a VM, but all of the associated resources the VM needs.

1. Select Home.
2. Select Resource groups.
3. Select the [sandbox resource group name] resource group.

You should see a list of resources in the resource group. The storage account and virtual network are associated with the Learn sandbox. However, the rest of the resources were created when you created the virtual machine. By default, Azure gave them all a similar name to help with association and grouped them in the same resource group.

Congratulations! You've created a resource in Azure and had a chance to see how resources get grouped on creation.

Clean up

The sandbox automatically cleans up your resources when you're finished with this module.

When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.

Describe Azure virtual machines

Azure Virtual Machines (VMs) offer Infrastructure as a Service (IaaS), providing virtualized servers with control over the operating system (OS), software, and hosting configurations. You can use VMs for custom software or hosting while Azure manages the physical infrastructure.

Key Features:

• Virtual Machine Scale Sets: Automate scaling by grouping identical VMs that auto-scale based on demand.
• Availability Sets: Group VMs across update domains (for reboot schedules) and fault domains (for power/network separation) to increase resiliency.

Common Use Cases:

• Testing and Development: Quickly create or delete VMs for different setups.
• Cloud Applications: Scale with demand; pay only for resources used.
• Disaster Recovery: Use VMs for temporary operations during outages.

Azure VMs are ideal for migrating workloads from physical servers to the cloud, providing flexibility without managing physical hardware.

VM Resources

When you provision a VM, you’ll also have the chance to pick the resources that are associated with that VM, including:

• Size (purpose, number of processor cores, and amount of RAM)
• Storage disks (hard disk drives, solid state drives, etc.)
• Networking (virtual network, public IP address, and port configuration)

?

Describe Azure virtual desktop

Azure Virtual Desktop (AVD) is a cloud-based desktop and application virtualization service. It allows users to access a cloud-hosted version of Windows from any location, across various devices and operating systems.

Key Features:

• Centralized Security: Managed with Microsoft Entra ID, supports multifactor authentication (MFA), and uses role-based access control (RBAC).
• Data Security: Desktops and apps run in the cloud, reducing the risk of sensitive data being stored on personal devices.
• Multi-session: Supports Windows 10/11 Enterprise multi-session, allowing multiple users on a single VM.

This enables flexible remote work with enhanced security and broad application support.

Describe Azure containers

Azure Containers are a lightweight virtualization technology that allows you to run multiple applications on a single host without managing the underlying operating system, unlike virtual machines (VMs). Containers are agile, scalable, and designed to respond dynamically to changing demand.

Key Concepts:

• Containers: Virtualized environments running on a single host (physical or virtual). Unlike VMs, you don't manage the OS, making containers more lightweight and quicker to deploy.
• Azure Container Instances (ACI): A Platform as a Service (PaaS) offering that runs containers without the need to manage VMs or additional services. It’s the simplest way to run containers in Azure.
• Azure Container Apps: Similar to ACI but with additional features like load balancing and scaling, which makes your solution more elastic.
• Azure Kubernetes Service (AKS): A container orchestration service that simplifies managing a large fleet of containers by handling scaling, deployment, and lifecycle management.

Use Cases:

Containers are ideal for microservice architecture, where applications are broken down into smaller, independent services (e.g., front end, back end, storage) that can be scaled and updated separately without affecting the whole application.

Describe Azure functions

Azure Functions is a serverless, event-driven compute service that allows you to run small pieces of code (called functions) in the cloud without the need to provision or manage infrastructure like virtual machines or containers. Azure Functions automatically handle scaling, resource management, and billing based on the actual compute usage.

Key Features and Benefits:

• Serverless computing: You don’t need to manage or maintain servers, as the functions are triggered by events (like HTTP requests, timers, or messages from other Azure services) and run on demand.
• Cost-efficient: You only pay for the execution time and the compute power your functions consume while they are running, not when they’re idle.
• Event-driven architecture: Azure Functions are triggered by various events, making them ideal for applications that rely on event-driven workflows like data processing, real-time alerts, or automation tasks.
• Auto-scaling: Functions automatically scale up or down depending on the demand, which is useful for unpredictable workloads or workloads with varying usage patterns.
• Stateless and stateful options: Stateless (default): Functions behave as if they restart with each new event, without retaining previous state. Durable Functions (stateful): Enable state management, allowing you to chain functions and track workflows across multiple events.

Use Cases:

• Microservices: Ideal for breaking down applications into smaller, independently deployed components.
• Automated workflows: Such as processing files in Azure Blob Storage, running background tasks, or responding to database changes.
• Webhooks or API calls: Respond to REST requests in real-time.

Azure Functions is a core part of the serverless computing model and provides flexibility for building efficient, scalable cloud applications with minimal infrastructure management.

Describe application hosting options

Azure provides several application hosting options, each designed to meet different needs based on the level of control, scalability, and the nature of the app. Here are the main hosting options:

1. Virtual Machines (VMs)

• Pros: Provides automation, scaling, and flexibility for complex workloads.
• Cons: Requires familiarity with Kubernetes for managing deployments.

5. Azure Functions

• Overview: A serverless computing option where you write small pieces of code (functions) that run on demand, triggered by events like HTTP requests or timers. No need to manage servers or infrastructure.
• Use Cases: Ideal for event-driven, stateless operations like background tasks, scheduled jobs, or real-time data processing.
• Pros: Cost-effective, scales automatically, and requires no server management.
• Cons: Best suited for short-running, stateless workloads.

Each of these options provides different levels of control and management, making it easier to choose the right solution based on the needs of your application, whether you require maximum control (VMs), fast scaling (containers), or a fully managed platform (App Service and Azure Functions).

Describe Azure virtual networking

Azure Virtual Networking (VNet) enables Azure resources, like VMs and databases, to communicate securely with each other, the internet, and on-premises networks.

Azure virtual networking supports both public and private endpoints to enable communication between external or internal resources with other internal resources.

• Public endpoints have a public IP address and can be accessed from anywhere in the world.
• Private endpoints exist within a virtual network and have a private IP address from within the address space of that virtual network.

Key Capabilities:

• Isolation and Segmentation: Create isolated virtual networks with private IPs and subnets.
• Internet Communication: Public endpoints enable access from the internet, while private endpoints are used for internal communication.
• Azure Resource Communication: Azure services like VMs and databases can securely communicate.
• On-Premises Connectivity: Connect on-premises and Azure resources via VPN or ExpressRoute for private links.
• Traffic Routing: Use custom route tables to control traffic, or allow Azure to handle it automatically.
• Traffic Filtering: Use Network Security Groups (NSGs) and virtual appliances for security.
• Connect virtual networks: Connect multiple virtual networks privately across regions using the Azure backbone network.

These features allow for secure, scalable, and flexible networking across both Azure and on-premises environments.

?

Describe Azure virtual private networks

Azure Virtual Private Networks (VPNs) provide secure, encrypted connections between private networks over the public internet. This allows organizations to safely share sensitive information across untrusted networks.

Key Points:

• VPN Gateway: Connects Azure virtual networks to on-premises networks or other virtual networks. Traffic is encrypted in a private tunnel.
• Types of VPNs: Policy-based: Encrypts traffic based on static IP address rules. Route-based: Uses IP routing for flexible, resilient connectivity, ideal for complex environments.
• High Availability Options: Active/Standby: Automatically switches to a standby instance during maintenance or failure. Active/Active: Uses two public IPs for simultaneous connections to ensure better uptime. ExpressRoute Failover: Provides a secure backup connection for ExpressRoute outages. Zone-redundant gateways: Ensures higher availability by deploying VPN gateways across Azure availability zones.

This approach provides secure, flexible, and highly available network connectivity between Azure and other networks.

Describe Azure ExpressRoute

5. Alias Records: Can link to Azure resources (e.g., IP addresses, Traffic Manager) and automatically update when the underlying resource's IP changes.

Note: Azure DNS does not sell domain names but can manage them once purchased from third-party registrars.

Describe Azure storage accounts

An Azure Storage Account provides a unique namespace for your data, accessible worldwide via HTTP or HTTPS. It ensures secure, highly available, durable, and scalable storage.

When creating a storage account, you choose the account type, which determines supported services and redundancy options for data protection. These redundancy options include:

• Locally Redundant Storage (LRS)
• Geo-Redundant Storage (GRS)
• Read-Access Geo-Redundant Storage (RA-GRS)
• Zone-Redundant Storage (ZRS)
• Geo-Zone-Redundant Storage (GZRS)
• Read-Access Geo-Zone-Redundant Storage (RA-GZRS)

Each storage account also gets a unique endpoint, ensuring a globally accessible namespace in Azure.

Describe Azure storage redundancy

Azure Storage redundancy ensures your data is protected and highly available by creating multiple copies of it. There are two key types of redundancy:

1. Primary Region Redundancy: Locally Redundant Storage (LRS): Data is replicated three times within one data center. 11 nines Zone-Redundant Storage (ZRS): Data is replicated across three availability zones for higher durability and availability. 12 nines
2. Secondary Region Redundancy (for regional disaster protection): Geo-Redundant Storage (GRS): Data is replicated to another region asynchronously. 16 nines Geo-Zone-Redundant Storage (GZRS): Combines ZRS in the primary region and replicates data to another region. 16 nines

• Use Cases: Migrating virtual machines (VMs), physical servers, databases, and web applications.

2. Azure Data Box:

• What it does: Physically transfers large volumes of data (up to 80 TB) using a secure device.
• How it works: Azure ships a device to your location, you load the data, and send it back for Azure to upload.
• Use Cases: Ideal for moving large datasets when network transfer isn't practical, for one-time or periodic transfers, and disaster recovery.

In short, Azure Migrate is for real-time or online migrations, while Azure Data Box is for transferring massive amounts of data offline using a physical device.

Identify Azure file movement options

Azure provides several tools for moving or managing individual files or small groups of files:

1. AzCopy: A command-line tool to copy files or blobs to/from Azure Storage. You can upload, download, or sync files. It's a one-way sync, meaning it only copies files from the source to the destination.
2. Azure Storage Explorer: A graphical app to manage files in Azure Storage. You can upload, download, or move files between accounts, and it uses AzCopy in the background.
3. Azure File Sync: Syncs your on-premises Windows file server with Azure Files. It allows bi-directional syncing, meaning changes made in either location are updated in both. You can access files locally using standard Windows protocols like SMB, and cloud tiering ensures frequently accessed files are stored locally, while others stay in the cloud.

These tools help you efficiently move or manage your files between on-premises environments and Azure.

Describe Azure directory services

Azure Directory Services mainly revolves around Microsoft Entra ID (formerly known as Azure Active Directory) and Microsoft Entra Domain Services. Here's a simplified overview:

1. Microsoft Entra ID: It’s a cloud-based identity and access management service. You can use it to sign in and manage access to Microsoft services (like Microsoft 365) and any cloud apps you develop. It helps secure identities by providing features like single sign-on (SSO), multifactor authentication, and password resets. It’s great for IT admins, developers, and users to manage access, develop apps with secure logins, and perform tasks like password resets. You can also connect your on-premises Active Directory (AD) with Microsoft Entra ID to unify your identity management between the cloud and on-premises. This is done using Microsoft Entra Connect, which keeps user identities synced.
2. Microsoft Entra Domain Services: This service provides traditional domain services (like domain join, group policy, and LDAP) in the cloud, without needing to manage domain controllers. It’s useful for running legacy applications in the cloud that can’t use modern authentication or for simplifying the management of AD services in Azure. It synchronizes with Microsoft Entra ID so that users can sign in with their existing credentials and use common domain features in the cloud.

In short, Microsoft Entra ID handles cloud identity management, and Microsoft Entra Domain Services provides traditional AD services in the cloud. Both make it easier to manage users and resources in both on-premises and cloud environments.

Describe Azure authentication methods

Azure offers several authentication methods to verify who you are when accessing apps or services. Here’s a simple breakdown:

1. Passwords: The most common way to sign in, but not very secure on their own. It's like showing your ID card, but it's not the safest option.
2. Single Sign-On (SSO): With SSO, you log in once and get access to multiple apps or services without needing to sign in again for each one. It simplifies things, so you only have to remember one set of login details.
3. Multifactor Authentication (MFA): MFA adds an extra layer of security. After entering your password, you'll also need something else, like a code sent to your phone or a fingerprint scan. This way, even if someone has your password, they can't log in without that second factor.
4. Passwordless Authentication: With passwordless methods, you don’t need to remember a password. Instead, you can use something like: Windows Hello for Business: A fingerprint or face scan linked to your computer. Microsoft Authenticator App: A notification on your phone where you confirm your identity with a PIN or fingerprint. FIDO2 Security Keys: A physical key (like a USB stick) that you use to log in, replacing the need for a password.

In summary, Azure supports both traditional passwords and more advanced methods like SSO, MFA, and passwordless options to ensure both convenience and high security.

Describe Azure external identities

Azure External Identities allow people from outside your organization to access your apps and resources securely, using their own login credentials. This is useful when you need to work with partners, vendors, or even customers.

Here’s a simple explanation:

• External users (like partners or customers) can sign in using their existing accounts, such as Google or Facebook, or even their work accounts. This way, they don’t need to create a new username and password for your system.
• Business-to-Business (B2B) collaboration allows these external users to use their preferred identity to access your company’s apps, just like your internal employees. You control what they can access.
• B2B Direct Connect lets organizations connect directly, like through Teams, without needing to add users to your system. You can collaborate while the external users stay in their home systems.
• Business-to-Customer (B2C) is for consumer apps, allowing users (like customers) to log in with their own social media or other accounts to access apps you build for them.

In short, Azure External Identities make it easy and secure to let people from outside your organization work with your apps or services using their existing accounts.

Describe Azure conditional access

Azure Conditional Access is a security feature that helps control who can access your organization's resources based on certain conditions. Think of it like a security guard who checks different factors before allowing someone in. Here’s how it works:

1. Identity Signals: When someone tries to access a resource (like an app or data), Conditional Access looks at different signals: Who is trying to access (the user). Where they are trying to access it from (their location). What device they are using (like a company laptop vs. a personal phone).
2. Decision Making: Based on these signals, Conditional Access makes a decision: If the user is at their usual location and using a trusted device, they might be allowed full access. If they are trying to access from an unusual or risky location, they might be blocked or asked for extra verification (like a code sent to their phone).
3. Enforcement: Once a decision is made, Conditional Access enforces it by either allowing access, denying access, or requiring additional authentication (like a password or a fingerprint).

When to Use Conditional Access:

• Require Extra Security: You can require users to provide a second form of authentication (like a code sent to their phone) depending on their role or location.
• Limit Applications: You can restrict access to only certain apps or devices that meet your security standards.
• Block Untrusted Access: If someone tries to access from a location or device that isn't trusted, you can block that access.

In summary, Azure Conditional Access helps keep your organization secure by making sure only the right people can access your resources under the right conditions.

Describe Azure role-based access control

Azure Role-Based Access Control (RBAC) is a system for managing user access to resources in your cloud environment, ensuring that people have the permissions they need without unnecessary privileges. Here’s a simplified overview:

Key Concepts:

1. Roles: Azure provides built-in roles (like "Reader" for viewing and "Owner" for full control) that bundle common permissions. You can also create custom roles tailored to specific needs.
2. Role Assignments: Instead of assigning permissions individually, you assign users or groups to a role. For example, when a new engineer joins, adding them to the "Engineer" role grants them the same access as others in that role.
3. Scopes: Roles are assigned to specific scopes, which can be: Management Group: A collection of subscriptions. Subscription: A single Azure subscription. Resource Group: A group of related resources. Single Resource: A specific Azure resource.
4. Hierarchy: RBAC is hierarchical, meaning that if you grant permissions at a higher level (like a management group), those permissions are inherited by all lower levels (like subscriptions and resource groups).
5. Enforcement: Azure Resource Manager enforces RBAC by managing actions taken on resources. It uses an “allow” model, meaning if you have permissions from multiple roles, you can perform any actions those roles allow.

Benefits:

RBAC simplifies access management, making it easier to control permissions for large teams. By grouping users into roles, you can quickly add or remove access, maintaining security and minimizing risks in your Azure environment.

Describe Zero Trust model

The Zero Trust model is a security approach that assumes every access request is a potential threat, regardless of whether it's from inside or outside the organization. Here’s a simplified overview:

Key Principles:

1. Verify Explicitly: Always check the identity and context of users and devices before granting access.
2. Least Privilege Access: Give users the minimum access they need to do their jobs. This limits the potential damage if an account is compromised.
3. Assume Breach: Act as if a breach has already happened. This means segmenting access, encrypting data, and using analytics to monitor for threats.

Transitioning to Zero Trust:

• Traditional Security: Previously trusted devices inside the corporate network while restricting external access.
• Zero Trust: Requires authentication for every access request, regardless of location. This ensures only authorized users can access resources.

Benefits:

• Better Security: Reduces the risk of attacks by verifying every request.
• Supports Remote Work: Allows secure access from any device or location.
• Compliance: Helps meet regulatory standards by enforcing strict access controls.

In essence, Zero Trust enhances security by treating every access request as potentially unsafe, ensuring that only the right people get access to the right resources.

Describe defense-in-depth

Defense-in-Depth is a security strategy that protects sensitive information using multiple layers of defense. This approach ensures that if one layer is breached, others are still in place to prevent unauthorized access. Here’s a simplified breakdown:

Key Layers of Defense:

1. Physical Security: Protects data centers and hardware with locks, cameras, and controlled access.
2. Identity and Access: Ensures only authorized users can access systems, using strong passwords and multi-factor authentication.
3. Perimeter Security: Shields against external attacks with firewalls and DDoS protection to filter out harmful traffic.
4. Network Security: Controls communication between resources, limiting access to reduce the risk of attacks spreading.
5. Compute Security: Secures servers and virtual machines by keeping software updated and using antivirus protection.
6. Application Security: Integrates security measures during the development of applications to reduce vulnerabilities.
7. Data Security: Protects sensitive data stored in databases and cloud services, ensuring it is accessible only to authorized users.

Summary:

By combining these layers, defense-in-depth provides a comprehensive security framework that slows down attacks and enhances data protection. Each layer acts as an additional barrier, making it harder for attackers to succeed.

Describe factors that can affect costs in Azure

Several key factors affect Azure costs:

1. Resource Type: The type of resource (VM, storage, database) and settings (region, performance tier) influence costs. Larger resources or specific regions may cost more.
2. Consumption: Pay-as-you-go means you pay for what you use. Reserved resources offer discounts for consistent workloads, while extra usage is billed at regular rates.
3. Maintenance: Regularly monitor and clean up unused resources (like storage or networking) to avoid unnecessary costs.
4. Geography: Costs vary between regions due to local factors like energy prices. Data transfers between regions may also incur charges.
5. Network Traffic: Inbound transfers are often free, but outbound data (leaving Azure) is charged based on geographic zones.
6. Subscription Type: Some subscriptions offer free services or usage credits. Enterprise agreements may include discounts.
7. Azure Marketplace: Third-party solutions in the marketplace may add to costs, as you pay for both Azure and the vendor's service.
