Introduction to Serverless Architecture

Introduction to Serverless Architecture

Whether you are completely new to web development or have been in the industry for years, you may have heard the term "serverless" mentioned here and there. While it may sound like a buzzword to some, serverless architecture is a very real and useful approach to building web applications.

In this post, we will discuss what serverless architecture actually is, why it has become so popular in recent years, its benefits, and some popular serverless services that developers can use to build their applications.

What is Serverless Architecture?

In traditional web development, web applications run on servers that are responsible for handling incoming requests from users, processing them, and returning the required response. However, with the advent of the cloud computing era, a new approach to web development has emerged: serverless architecture.

Serverless architecture is a cloud computing approach where the cloud vendor manages the infrastructure and automatically allocates resources to your application as needed. Unlike traditional web development, where you have to manually manage and configure servers, with serverless architecture, you only pay for the resources that your application actually uses.

Why Serverless Architecture?

Serverless architecture has gained immense popularity among developers in recent years due to several reasons, including:

  • Cost-Effective: With serverless architecture, you only pay for the compute resources that are used. This means that you do not have to pay for idle computing resources.

  • Scalability: Serverless architecture enables you to scale your application automatically as your demand grows. This ensures that your application is always up and running, even during peak traffic periods.

  • Simplified Infrastructure: Serverless architecture allows you to focus on building your application without having to worry about managing the underlying infrastructure. This saves you time and resources that would otherwise be required to configure and maintain infrastructure.

  • Reduced Time-to-Market: With serverless architecture, you can develop and deploy your application much faster than with traditional web development. This is because you do not have to worry about infrastructure setup, which can take a significant amount of time and effort.

Serverless Services

There are several cloud vendors that offer serverless services, including:

AWS Lambda - AWS Lambda is Amazon's serverless computing platform that allows developers to create and run functions that respond to events automatically. Lambda automatically scales to handle incoming requests and provides high availability without any operational overhead.

Azure Functions - Azure Functions is a serverless compute service that lets developers run event-triggered code without having to worry about the infrastructure behind it. It provides built-in support for various triggers such as HTTP, timers, and queues.

Google Cloud Functions - Google Cloud Functions is a serverless compute service that allows developers to run single-purpose, lightweight functions that scale automatically. It provides excellent integration with Google Cloud services and supports various event triggers.


Serverless architecture has transformed the way web applications are built and deployed. With its cost-effective, scalable, and simplified infrastructure, it has become the go-to choice for modern web developments. The serverless services offered by cloud vendors like Amazon Web Services, Microsoft Azure, and Google Cloud Platform have made this approach of building applications much easier and accessible to developers of all levels. If you are a developer looking to build your next web application, consider leveraging serverless architecture and the services that come with it.
