What is Serverless Computing
Updated on 02nd Aug, 23 9.8 K Views

The way businesses develop and deliver applications is changing because of a revolutionary technology called serverless computing. Businesses can significantly save on costs with serverless computing because they only pay for the resources they use. Additionally, serverless computing offers automatic scaling, allowing businesses to grow their applications and services to satisfy customer demand swiftly. So let’s find out why companies should consider using serverless computing!

Introduction to Serverless Computing

Serverless computing refers to the methodology of building and running applications and services without having direct control over the underlying infrastructure. It frees developers from the need to manage servers, storage, and networking, providing them with a platform that handles these aspects in the background. This approach empowers developers to focus their efforts on creating and refining their applications and services without being burdened by the complexities of infrastructure management. 

Function-as-a-Service, or “FaaS,” is another name for serverless computing. In the FaaS concept, programmers create and submit their code to a serverless platform. The serverless platform then executes the code and controls the supporting infrastructure. Depending on the application or service demand, the platform will dynamically scale the resources as necessary.

Why Use Serverless Computing?

Why Use Serverless Computing

There are several benefits of serverless computing to businesses, allowing them to stay competitive in a rapidly changing market. There are several reasons why serverless computing has become popular among developers. 

Some of the key benefits of using serverless computing include:

  • Serverless computing can scale up or down autonomously, depending on the application’s needs. This indicates that the application can manage unexpected traffic spikes without requiring manual intervention. When managing infrastructure and resources, this can result in considerable time and financial savings.
  • With serverless computing, you only pay for the resources you use while the function is running. This is known as a pay-per-use model. Compared to typical server-based solutions, where you have to pay for resources that might not be completely utilized, this can be substantially less expensive.
  • As developers don’t have to spend time and resources operating and deploying servers, serverless computing can assist shorten the time it takes for new apps to reach the market. This can make it easier for organizations to swiftly and effectively adapt to shifting market needs.
  • In serverless computing, the infrastructure, including the servers, storage, and networking, is managed by the cloud provider. As a result, developers won’t have to worry as much about the supporting infrastructure and can concentrate on building and distributing code. This can lower operational expenses and ease the management of applications.
  • The ability to develop and deploy applications using a range of programming languages and frameworks makes serverless computing adaptable. As a result, businesses won’t be constrained by the infrastructure and can select the programming language and framework that best suit their needs.

How does Serverless Computing Work?

Serverless computing is a cloud computing model where the cloud provider manages the infrastructure and automatically provisions, scales, and contains the servers required to run and execute applications. The term “serverless” does not mean that no servers are involved. Instead, developers do not have to worry about managing or maintaining servers.

In a serverless architecture, developers only need to write and deploy code, and the cloud provider takes care of the rest. When a user sends a request to an application, the cloud provider automatically provisions the necessary resources, runs the code, and charges the user based on the resources used. It makes serverless computing ideal for applications with unpredictable or fluctuating traffic, as developers only pay for the resources they use.

Serverless computing is often used with Function-as-a-Service (FaaS) platforms, such as AWS Lambda, Azure Functions, or Google Cloud Functions. FaaS platforms allow developers to write code in the form of functions, which are small, self-contained pieces of code that perform a specific task. These functions can be triggered by events, such as a user uploading a file or a database update, and can be written in various programming languages.

Serverless Computing Tools

Serverless Computing Tools

For serverless computing, there are a variety of tools, each with a special set of features and advantages. Developers can choose the option that best satisfies their needs, allowing them to write and distribute code swiftly and worry-free.

  • AWS Lambda- Amazon Web Services (AWS) offers the serverless computing technology known as AWS Lambda. It enables programmers to create and distribute code without concern about the supporting infrastructure. Multiple programming languages are supported by AWS Lambda, which also connects with other AWS services.
  • Google Cloud Functions- A serverless computing platform is offered by Google Cloud through Google Cloud Functions. It enables programmers to create and publish code that reacts to actions taken by other Google Cloud services. Multiple programming languages, such as Node.js, Python, etc., are supported by Google Cloud Functions.
  • Microsoft Azure Functions- The serverless computing platform provided by Microsoft Azure is called Microsoft Azure Functions. It enables programmers to create and publish code that reacts to actions taken by other Azure services. C#, Java, and Python are just a few of the programming languages supported by Azure Functions.
  • IBM Cloud Functions- The serverless computing platform offered by IBM Cloud is known as IBM Cloud Functions. It enables programmers to create and publish code that reacts to occasions brought on by other IBM Cloud services. Swift, Python, and Node.js are just a few of the programming languages that are supported by IBM Cloud Functions.
  • OpenFaaS- OpenFaaS is a free and open-source platform for serverless computing that supports programmers to conduct operations on both on-premises and cloud infrastructure. It may be integrated across multiple platforms for container orchestration and supports several programming languages.

Serverless Computing Examples

Serverless computing is used in a variety of applications. Below are some of the use cases of serverless computing that businesses across various sectors employ:

  • Web Applications
    Web applications can be created and deployed using serverless computing and can scale automatically based on user demand. This can range from small personal websites to significant e-commerce portals with millions of users.
  • Mobile Applications
    Serverless computing can be leveraged to develop and scale mobile applications efficiently and rapidly, catering to diverse user demands. It encompasses a wide range of mobile app types, from simple ones to sophisticated business software, empowering seamless growth and responsiveness without the hassle of infrastructure management. 
  • IoT Applications
    Internet of Things (IoT) applications can be developed and implemented using serverless computing, allowing for real-time data processing and analysis from connected devices. This can include everything from smart household appliances to industrial IoT sensors.
  • Data processing
    Serverless computing can process massive amounts of data quickly and effectively. This includes everything from batch processing and data warehousing to real-time data streaming.


Serverless computing aims to do away with server management, rather than servers. With this innovative cloud computing model, developers can concentrate on writing code and providing value to their customers as the cloud provider takes care of the infrastructure.

Serverless computing is likely to dominate as technology progresses, and we can anticipate fresh developments and advancements that will increase its usability and power for developers to accelerate businesses of any size, worldwide.
