AWS in the DevOps industry!
What is DevOps?
DevOps if defined in short and simple is the combination of practices, cultural philosophies, and tools that help an organization improve its ability to deliver applications and services at high velocity: evolving and improving products at a faster pace when compared with organizations using traditional software development and infrastructure management processes. These practices increase the speed of an organizations development and deployment processes, and this speed enables organizations to better serve their customers and compete more effectively in the market.
How DevOps works?
Under a typical model used for DevOps, the teams for development and operations are no longer “siloed.” Often, these two teams are merged into a single team to enable developers and engineers to work across the entire application lifecycle, from development and test to deployment to operations, and it creates a workforce with a range of skills which are not limited to a single function. In some DevOps models, quality assurance and security teams may also become more tightly integrated with development and operations and throughout the application lifecycle. When a DevOps team works together as a whole to optimize security, this is sometimes referred to as DevSecOps.
These teams use practices to automate processes that historically have been manual and slow. They use a technology stack and tooling which help them operate and evolve applications quickly and reliably. These tools also help engineers independently accomplish tasks (for example, deploying code or provisioning infrastructure) that normally would have required help from other teams, and this further increases a team’s velocity.
Why to Use AWS for DevOps?
AWS provides a set of flexible services designed to enable organizations to build and deliver products faster and more reliably by implementing DevOps practices. These services simplify provisioning and managing infrastructure, deploying application code, automating software release processes, and monitoring your application and infrastructure performance. and services are fully managed which enables teams to focus on more important tasks rather than monitoring and deploying everything manually. and AWS services are based on a pay-as-you-go model so you only pay the services that have been used and only for as long as they have been used.
DevOps architecture in AWS
DevOps tools on AWS
AWS offers a lot of services or tools that help implementing DevOps in organizations – For best DevOps practices and results these tools are integrated with each other to utilize there full potential.
AWS provides services that help you practice DevOps in your organization. These tools depending on their role can be categorized into different sections :-
Continuous Integration and Continuous Delivery (CI/CD)
Continuous Integration (CI) is a software development practice where developers regularly merge their code changes into a central code repository, after which automated builds and tests are run. CI helps find and address bugs quicker, improve software quality, and reduce the time it takes to validate and release new software updates.
Continuous delivery is a software development practice where code changes are automatically prepared for a release to production. Continuous delivery expands upon continuous integration by deploying all code changes to a testing environment and/or a production environment after the build stage.
AWS CodePipeline?is a continuous delivery service that enables you to model, visualize, and automate the steps required to release your software. With AWS CodePipeline, the full release process can be modeled for building code, deploying to pre-production environments, testing your application, and releasing it to production. AWS CodePipeline then builds, tests, and deploys your application according to the defined workflow every time there is a code change.
AWS CodeBuild?is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. The developer would need to provision, manage, and scale your own build servers. CodeBuild scales continuously and can process multiple builds concurrently. CodeBuild offers various pre-configured environments for various versions of Microsoft Windows and Linux. Customers can also bring their customized build environments as Docker containers.
AWS CodeDeploy?is a fully managed deployment service that automates software deployments to a variety of computing services such as?Amazon Elastic Compute Cloud?(Amazon EC2),?AWS Fargate, AWS Lambda, and your on-premises servers. AWS CodeDeploy makes it easier for you to rapidly release new features, helps you avoid downtime during application deployment, and handles the complexity of updating your applications.
Microservices
Build and deploy a microservices architecture using?containers?or?serverless computing
Amazon Elastic Container Service (Amazon ECS)?is a fully managed container orchestration service that helps you easily deploy, manage and scale containerized applications. It deeply integrates with the rest of the AWS platform to provide a secure and easy-to-use solution for running container workloads in the cloud.
AWS Lambda?is a serverless compute service that lets you run code without provisioning or managing servers, creating workload-aware cluster scaling logic, maintaining event integrations, or managing runtimes. With Lambda, you can run code for virtually any type of application or backend service – all with zero administration. Just upload your code as a ZIP file or container image, and Lambda automatically and precisely allocates compute execution power and runs your code based on the incoming request or event, for any scale of traffic. You can set up your code to automatically trigger from over 200 AWS services and SaaS applications or call it directly from any web or mobile app. You can write Lambda functions in your favorite language (Node.js, Python, Go, Java, and more) and use both serverless and container tools, such as AWS SAM or Docker CLI, to build, test, and deploy your functions.
Infrastructure as Code
A fundamental principle of DevOps is to treat infrastructure the same way developers treat code.
AWS CloudFormation?is a service that enables developers to create AWS resources in an orderly and predictable fashion. Resources are written in text files using JavaScript Object Notation (JSON) or Yet Another Markup Language (YAML) format. The templates require a specific syntax and structure that depends on the types of resources being created and managed. You author your resources in JSON or YAML with any code editor such as?AWS Cloud9, check it into a version control system, and then CloudFormation builds the specified services in a safe, repeatable manner. A CloudFormation template is deployed into the AWS environment as a stack. You can manage stacks through the AWS Management Console, AWS Command Line Interface, or AWS CloudFormation APIs.
AWS OpsWorks?is a configuration management service that uses Chef, an automation platform that treats server configurations as code. OpsWorks uses Chef to automate how servers are configured, deployed and managed across your Amazon Elastic Compute Cloud (Amazon EC2) instances or on-premises compute environments. OpsWorks has two offerings, AWS Opsworks for Chef Automate, and AWS OpsWorks Stacks.

AWS Systems Manager?is a management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems. These capabilities help you define and track system configurations, prevent drift, and maintain software compliance of your EC2 and on-premises configurations.
AWS Config?is a fully managed service that provides you with an AWS resource inventory, configuration history, and configuration change notifications to enable security and governance. Config Rules enable you to create rules that automatically check the configuration of AWS resources recorded by AWS Config.
Monitoring and Logging
To facilitate this, feedback is critical. Robust monitoring, alerting, and auditing infrastructure is helpful for developers and operations teams to work together closely and transparently.
Amazon CloudWatch
Amazon CloudWatch metrics automatically collect data from AWS services such as Amazon EC2 instances, Amazon EBS volumes, and Amazon RDS DB instances. These metrics can then be organized as dashboards and alarms, or events can be created to trigger events or perform Auto Scaling actions.
AWS X-Ray
AWS X-Ray helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. With X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors.
AWS CloudTrail
To embrace the DevOps principles of collaboration, communication, and transparency, it’s important to understand who is making modifications to your infrastructure. In AWS, this transparency is provided by?the AWS CloudTrail?service. All AWS interactions are handled through AWS API calls that are monitored and logged by AWS CloudTrail. All generated log files are stored in an Amazon S3 bucket that you define. Log files are encrypted using?Amazon S3 server-side encryption?(SSE). All API calls are logged whether they come directly from a user or on behalf of a user by an AWS service.
Version Control
AWS offers version control host secure and highly scalable Git repositories in the cloud.
AWS CodeCommit?is a fully managed?source control?service that makes it easy for companies to host secure and highly scalable private Git repositories. You can use CodeCommit to securely store anything from source code to binaries, and it works seamlessly with your existing Git tools.
Platform as a Service
Deploy web applications without needing to provision and manage the infrastructure and application stack.
AWS Elastic Beanstalk?is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker on familiar servers such as Apache, Nginx, Passenger, and IIS.
You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring. At the same time, you retain full control over the AWS resources powering your application and can access the underlying resources at any time.
