Three Building Blocks Of Cloud Technology

Hardware and software are the most critical parts of a digitally managed and executed business. Technological developments in hardware have managed to put multiple computers in small phones in your pocket in a short time. Today, this software has also eliminated many hardware needs.

SaaS (Software as a Service)

SaaS (Software as a Service), a cloud provider develops, and maintains cloud application software, provides automatic software updates, and provides customers with pay–as–you–go software over the Internet. The public cloud provider manages all hardware and traditional software, including middleware, application software, and security. Therefore, SaaS (Software as a Service) customers can significantly reduce costs; It can deploy, scale, and upgrade business solutions faster than managing–premises systems.

In SaaS (Software as a Service) software, the data is hosted with the hosting method, and the service works with a cloud-based usage principle. Users can only access the relevant data using a browser and make edits and updates within the scope of the service received. Therefore, it is possible to benefit from this software, which is usually charged with monthly or annual subscriptions, with the “pay as you go” logic.

The institution’s task is to provide the software’s powerful hardware, basic infrastructure, application, and middleware management services.

The SaaS (Software as a Service) service, where security and management are provided centrally, is mainly used in business organizations as it is compatible with multi-user architecture.

What are the advantages?

1. Internet connection is sufficient for access.
2. It has hardware configuration and infrastructure compatible with average business and personal computers.
3. It is low cost, easy to use. Moreover, since it is scalable, there is the freedom to choose according to the size of projects and organizations.
4. Updates are made easily and quickly, without interrupting operations. No tests cause the system to slow down, and security updates do not take long.
5. Data is securely stored in the cloud. In this way, both data loss is not experienced, and the relevant data can be accessed from any device that accesses the software.

What are the disadvantages?

1. Sharing sensitive data with a service provider can create an uncontrollable situation.
2. There may be an incompatibility between SaaS and on-premises APIs. As a result, it isn’t easy to integrate with external software.
3. As the number of users increases, it may become harder to control. For example, a lack of updates in one of the users can affect all users.
4. Uninterrupted and fast internet access is a must. However, problems that may arise in the Internet connection may make it impossible to access the data.
5. There is a possibility of encountering performance drops. For example, the performance of a software service from a remote data center may be lower than desktop applications run with powerful hardware.

Almost any service that can be entered and logged to access, view, edit, and update later can be an example of SaaS. The best–known and widely used measure is email services. Services such as Gmail, Outlook, and Yandex Mail work with this logic.

PaaS (Platform as a Service)

PaaS (Platform as a Service) provider hosts everything in the data center, including servers, networks, storage, operating system software, databases, development tools. Customers can pay a flat fee to create a certain number of resources for a certain number of users, or they can choose a “pay–as–you–go” pricing method to only pay for the resources they use.

What are the advantages?

1. Scalable.
2. Extremely usable.
3. Automation of business policy.
4. Model Easy transition to a hybrid model.
5. Simple, cost-effective development and deployment of applications.

What are the disadvantages?

1. Integration:?The complexity of connecting data stored in an on-premises data center or off-premises cloud increases. This may affect which applications and services can be adopted with the PaaS?(Platform as a Service)?offering.
2. Vendor Lock:?The business and technical requirements that make decisions for a particular PaaS?(Platform as a Service)?solution may not apply in the future. If the vendor has not provided appropriate migration policies, switching to alternative PaaS?(Platform as a Service)?options may not be possible without impacting the business.
3. Data Security:?Organizations can run their applications and services using PaaS?(Platform as a Service)?solutions, but data on third–party, vendor–controlled cloud servers create security risks and concerns.
4. Runtime Issues:?PaaS?(Platform as a Service)?solutions may not be optimized for your chosen language and frameworks in addition to limitations with specific applications and services. Custom framework versions may not be used or perform appropriately with the PaaS?(Platform as a Service)?service.
5. Operational Limitation:?Customized cloud operations with management automation workflows may not apply in PaaS?(Platform as a Service)?solutions as the platform limits end–users operational capabilities.
6. Customization of Legacy Systems:?PaaS?(Platform as a Service)?may not be a plug–and–play solution for existing legacy applications and services. Instead, legacy systems may require various customizations and configuration changes to work with the PaaS?(Platform as a Service)?service.

IaaS (Infrastructure as a Service)

IaaS (Infrastructure as a Service) is a Cloud Computing service that provides basic computing, storage, and networking resources with an on-demand pay–as–you–go, model. IaaS (Infrastructure as a Service) is one of four types of cloud services, along with SaaS (Software as a Service), PaaS (Platform as a Service), and serverless.

By migrating your organization’s infrastructure to an IaaS (Infrastructure as a Service) solution, you can reduce on-premises data center maintenance, save on hardware costs, and gain real-time business insights. In addition, IaaS (Infrastructure as a Service) solutions offer the flexibility to scale up and down your IT resources on demand. It also helps you rapidly provision new applications and increase the reliability of your underlying infrastructure.

IaaS (Infrastructure as a Service) frees you from purchasing and managing physical server and data center infrastructure costs and complexity.

What are the advantages?

1. Provides better security.
2. Allows you to innovate quickly.
3. Allows you to focus on your work.
4. Let you bring new apps to users faster.
5. Reduces lag and provides high performance.
6. Increases stability, reliability, and supportability.
7. Eliminates capital expenses and reduces ongoing costs.
8. Responds?more quickly?to changing business conditions.

Types of IaaS (Infrastructure as a Service)

1. Hybrid IaaS
2. Private IaaS
3. Public IaaS
