Serverless architecture on websites

What is it and how does it work?

Understanding the Cloud-based Approach and its Benefits

In recent years, a new way of developing web applications has emerged: serverless architecture. Unlike traditional server-based architecture, which requires a fixed infrastructure to run applications, serverless architecture works on the basis of cloud computing. Here, there is no fixed server that needs to run permanently, but the application is executed by various cloud services. In this article, you will learn more about what serverless architecture is for websites and what advantages it offers.

What is serverless architecture?

Serverless architecture does not mean that there are no servers. Instead, it means that the developer no longer has to worry about managing servers. It means that the management of servers such as installation of operating systems, patches, updates, scaling and monitoring is handled by the cloud platform.

The developer only needs to focus on developing the application and code. This is achieved by using cloud services that provide a scalable and reliable infrastructure. These services are provided by cloud providers such as Amazon Web Services (AWS), Microsoft Azure or Google Cloud Platform.

How does serverless architecture work?

To understand serverless architecture, it is important to understand how traditional server-based architecture works. In this model, there is a fixed server that runs an application. When more resources are needed, another server has to be added, which slows down and complicates the whole process of scaling.

In the serverless architecture, on the other hand, applications are executed in the form of functions. Each function is considered an independent entity that serves a specific purpose. When a function is executed, the necessary storage, computing power and other resources are automatically provisioned.

To make this possible, a cloud service called 'Function as a Service' (FaaS) is used. This service executes the function when it is invoked and releases the resources when the function is finished. This allows for automatic scaling, as the service can automatically provision more resources to meet demands when the load is high.

Advantages of serverless architecture

Scalability: One of the main advantages of serverless architecture is scalability. Since functions are executed independently, each function can be scaled separately. If a particular function has a higher load, the number of resources for that function can be increased without affecting other functions.

Cost-effectiveness: Serverless architecture is also more cost-effective than traditional server-based architectures. This is because the developer only has to pay for the resources that are actually used. In the traditional model, the developer pays for the server whether it is actually used or not.

Auto-scaling: serverless architecture also enables auto-scaling, which means that the cloud service automatically provides more resources as the demand for the application increases. This means that the application is always available without the need for manual scaling.

Flexibility: Serverless architecture also provides more flexibility in the way applications are developed. Developers can focus on developing features and integrating cloud services instead of worrying about managing servers and infrastructure.

Less maintenance: Because the management of servers is handled by the cloud platform, much of the maintenance, patching and updates that would normally be required are eliminated. This saves time and resources and allows developers to focus on improving the application.

Conclusion

Serverless architecture offers many advantages over traditional server-based architectures. By using cloud services, developers can scale their applications without having to worry about managing servers and infrastructure. This leads to more flexibility, cost efficiency, and automatic scaling. If you are developing or upgrading your website or web application, consider serverless architecture as a possible option.
