Over the years, serverless computing in cloud computing has offered a set of benefits to web developers. In other words, it makes their work easy since it allows them to run apps without maintaining servers. So, in this blog, we will explore the concept behind serverless computing and help you clear all your doubts.

Continue to read for more.

Serverless computing in cloud computing gives a wide range of benefits over traditional servers. It has helped developers to run apps at a low cost with fast time-to-market. Besides, it stopped their need to worry about purchasing and managing servers. As a result, they can focus more on the business logic and writing front-end code for the apps.

Serverless does not mean 'no servers.' Instead, they explain the experience of developers with the servers. In other words, these servers are invisible to them. Therefore, they cannot manage or interact with these servers. Hence, today, we can observe many cloud service providers offering serverless platforms.

So, let us explore this concept through the following sections:

What is Serverless Computing in Cloud Computing?

Serverless computing is a subset of cloud computing that offers back-end services based on the user's needs. In other words, it is also an app development and execution model that allows users to build and run apps without managing or provisioning the back-end infrastructure or servers.

As a result, the serverless provider offers the users resources based on their demand while they take care of the server on their end. Hence, the users do not have to spend their energy and time handling these servers. Besides, there is some confusion regarding serverless computing.

The first one is the difference between cloud computing and serverless computing. So, serverless computing is a type of cloud computing. Cloud computing involves providing services over the Internet. These services can include managing systems, software, servers, and more. On the other hand, serverless computing involves offering back-end services by cloud providers.

However, the term 'serverless' is confusing since it does not mean a complete lack of servers. As a result, it refers to how the servers offered by the service providers are not within the reach of the users but are managed by the service providers themselves. Thus, serverless computing in cloud computing helps developers focus on writing their codes for front-end apps and business logic.

Earlier, the web developers themselves had to manage the servers and build apps. Besides, they had to own hardware to run the server. However, it was expensive and took a lot of time and effort. With the help of cloud computing, developers can now rent and save server space. Besides, serverless computing helped them save more money since it allows users to pay based on their use.

So, now, let us explore the benefits of serverless computing.

What are the Benefits of Serverless Computing?

Serverless computing in cloud computing has gained much demand in the software domain because of its wide range of benefits. It has offered advantages over traditional servers and services. So, let us dive deep into its benefits for more insights:

Fewer Costs

One of the key benefits of serverless computing is its pay-as-you-go model. It enables the users to pay only when they use the server. So, they get charges based on the duration and unit they use. However, in traditional cloud services, the users had to pay for unused server space or idle CPU period. With cloud services like serverless compute service in AWS, the users never get additional charges for the operations.

Highly Scalable

Serverless computing in cloud computing is highly scalable and flexible. The users can scale up and down the server units based on the request inflows. So, if the user base or usage grows, the servers will run and end as the user needs them. Besides, the service providers will handle the scaling on the demand of the users.

As a result, if there is a high request inflow, the vendors will increase the server units. On the other hand, if there is less request inflow, the vendors will decrease the number of server units.

No Server Management

The developers can focus on code creation and business logic since cloud service providers help manage the servers. In other words, the service providers will run the app's code as a third party.

Quick Updates

The developers can update and add new features to the application using serverless computing in cloud computing. The users can update one function at a time. It means the developers do not need to change the whole application.

Faster Time-to-Market

Serverless architecture allows developers to change the code piece by piece. As a result, they can save time and resources for releasing the product to the market.

Reduce Latency

Apps are not dependent on the origin servers. Therefore, the developers can run the app's code on servers from anywhere they want. So, the developers can also run the apps on servers close to the end users. As a result, the request and response will only take less distance to travel in the network. Thus, serverless computing in cloud computing reduces latency.

What are the Components of the Serverless Architecture?

The components of serverless computing increased its widespread use. Serverless platforms have become useful for developers to work on their core tasks. So, in this section, we will explain more about the architecture of serverless computing.

Function as a Service (FaaS)

FaaS is a fundamental block of serverless computing. The primary purpose of FaaS is to allocate resources based on the user's demand. The developer can choose a FaaS depending on the cloud environment.

Client Interface

The client interface is essential for serverless computing in cloud computing. They help support requests, integrations, and stateless interactions. Besides, they are compatible with high and low data transfers.

Web Server

The web server is the platform that hosts and initiates stateless interactions, user scripts, FaaS responses, and more.

Security Service

This component keeps serverless computing secure and safe for the users. In other words, it authenticates and validates responses and interactions. As a result, it prevents the possibility of attacks or threats.

Back-end Database

This component of serverless computing in cloud computing helps store user data. As a result, the developers can use this element as a BaaS solution to ingest different data types. Besides, the developers can reduce the maintenance and admin efforts.

API Gateway

The API gateway is a component that helps connect the FaaS and client interface. Hence, the API gateway triggers the response through FaaS whenever the user initiates a request.

What are the Use Cases of Serverless Computing?

Given below are the use cases and applications of serverless computing. Let us briefly describe each of them as follows:


Serverless computing in cloud computing supports microservices architecture. With the attributes of serverless, microservices can create small services and perform a single job using APIs to communicate.

API back-ends

You turn any actions into HTTP endpoints on a serverless platform. These actions are suitable for web clients. As a result, you can assemble web actions into an API with the help of an API gateway. Thus, it helps bring more security and benefits to the back ends.

Data Processing

You can use serverless computing to process audio, images, text, and videos. Thus, you can employ the platform for enriching, transforming, and cleansing data.

Massive Parallel Computing Operations

With the help of serverless computing in cloud computing, you can handle parallel tasks. As a result, you can perform tasks from data searches and processing to map operations.


There are many benefits of Chatbots, handle a myriad of requests every day. Therefore, serverless is suitable for applications like chatbots to manage user needs and encourage functional features.

Event-based Application

Event-based apps involve services like e-commerce that rely on user actions and user-triggered events. As a result, serverless can help the apps to scale up to quick user demands and more.

IoT and Smart Devices

Serverless is best suited for IoT and smart devices since both depend on real-time data exchanges. Besides, serverless can help these devices handle a high volume of data without any complications.


Serverless computing in cloud computing is an ideal choice if you are looking for options to handle your business operations. It is cost-effective, highly scalable, and flexible for user-centric apps. You can conduct different tasks, including data processing, with ease.
