What is Serverless Computing And How It Works

The world is changing quickly and rapidly at a quick speed. The technology and underlying architecture under it are evolving even more rapidly. In this article, we will examine the new word “Serverless Computing.” We will try to figure out what it is, and also the way it works.

What is Serverless?

Serverless is the native cloud infrastructure that helps you to bring all of your operating activities into AWS. It increases your flexibility and progress. Serverless lets you develop and run server-free applications and services.

What is Serverless Computing?

Serverless Computing allows developers to create apps more easily. It reduces the need for database maintenance. The cloud service provider pays for the technology needed. It helps to execute the code dynamically for serverless applications.

It is important to remember that servers still need coding to grasp the concept of serverless computing. The name is because of the functions involved with the installation and maintenance of resources. They are not accessible to the operator.

This approach encourages developers to concentrate more on business logic. They have more value for the core market. Serverless computing allows teams to boost their efficiency and sell their goods quickly. It will enable companies to leverage capital efficiently and keep focused on innovation.

How does it work?

Developers focus on Serverless to perform basic tasks. As a consequence, cloud services provide Functions as a Service (FaaS). Below you can see how serverless functionality is written and implemented.

  • The developer writes a function.

Sometimes, this functionality performs a special function within the program code.

  • The developer describes a case.

The case unlocks the features of the cloud service provider. An HTTP request is a typical form of occurrence.

  • The event is enabled.

If the possible case is an HTTP message, a click or related operation triggers the case.

  • The role is performed.

The cloud provider checks when a service instance is currently operating. If not, the feature begins with a new one.

  • The outcome is provided to the customer.

Inside the program, the user can see the outcome of the performed function.

Benefits of Serverless Computing

  • No control of facilities

Using professionally administered facilities, developers can reduce administrative activities. Also, concentrate on essential business principles. You basically deploy the code with a serverless platform, which is highly accessible.

  • Dynamic Optimization

The architecture of serverless computing scales up and down within seconds to satisfy the specifications of each workload.

  • Quicker Marketing Time

Serverless applications decrease operational dependency on each development cycle.  They improve the versatility of development teams to provide more features in a shorter period.

  • Effective usage of resources

Moving into serverless technology allows companies to reduce TCO and resource utilization and accelerate creativity.


It is important to note that serverless computing is recent and unrefined. Any cases of design also better fit the conventional architecture. If you want to migrate to serverless, first validate the FaaS programs to ensure that it runs fine. FaaS is a major cloud-based revolution that is expected to stabilize in the upcoming years.
