Best 10 Serverless Platforms

Before the Serverless Computing framework, developers would spend hours solving coding issues. Next, the operation team would spend countless hours helping developers to figure out the code written by them and made sure the computers used for running the program are operating smoothly.

The latter part was an endless task to complete for sure. And then arrived the age of Serverless Computing with the launch of AWS Lambda in 2014. The serverless computing paradigm helps developers forget about the worries related to the operating system their code runs on because the service provider effectively takes care of these things. 

What is Serverless Computing?

In serverless computing, an execution model for the cloud, a cloud provider dynamically allots and seeks payment from the user solely for the compute resources and storage required for the execution of a specific piece of code.

The serverless approach allows app developers to work with servers, but in a serverless way by handing over maintenance and provisioning tasks to the cloud provider.

A team involved in writing the code and using it can rely on the fully-managed cloud service that will effectively manage a host, patch a host, and deal with everything on an operating system level.

There is no requirement for the developer to provide or manage the server at all. All he needs to do is focus entirely on writing codes. 

Why go for a serverless architecture?

A serverless approach benefits an app developer in two significant ways:

  • No server management
  • Automatic scaling
  • Pay according to resource allocation

App developers can develop event-driven applications in a serverless environment. For instance, developers might have to deploy data coming from IoT devices with intermittent Internet connectivity or have an application with fluctuating event requests.

In both cases, a serverless approach can handle peak work capacities. Besides, the serverless approach follows a payment model where you pay only for a compute resource and the required storage, rather than buying hardware that sits idle for most of the time. 

With serverless computing, developers can focus fully on their business goals (write codes), rather than investing time and effort in solving infrastructural problems. 

Top 10 Serverless Providers

In this part of the context, you will gain insight into the top ten serverless providers. 


Back4App is the best open-source Backend-as-a-Service developed to offer amazing flexibility and scalability to app developers. More and more organizations are promoting this serverless framework as this BaaS features most of the backend applications on cloud service.

AWS Lambda

AWS Lambda is a serverless compute service that monitors lambda functions. AWS Lambda helps developers write code without managing servers and execute them unfailingly. The app developers get the authority to report metrics through Amazon CloudWatch after executing the functions.

This serverless approach lets developers scale applications by executing the code and analogically processing each trigger response individually. Furthermore, AWS Lambda facilitates a payment model where you must pay for the compute time you consume. This being the case, you can optimize your code execution time by selecting a memory size that matches your function.

You can initialize your functions and keep them ready to be acknowledged within milliseconds by activating Provisioned Concurrency. Developing an app with AWS Lambda is as easy as writing the code in lambda’s editor, setting up the code using the required compute resources, and paying for the time you use.

Cloudflare Workers

The Cloudflare Worker is a serverless platform that effectively runs serverless functions as closely as possible to the end-user. In Cloudflare Worker platform, app developers write functions in JavaScript against the API service workers.

In other words, developers can use all the functionalities that a service worker offers to write the code. The developers execute the code by leveraging the Chrome V8 engine. After the developers write and execute the codes, they host the code in Cloudflare’s data centers accessible throughout the world.

Cloudflare Worker offers developers the simplicity of dealing with the complete stack of software underneath the application, leaving them free to pay attention to the logic of the application. Besides, serverless computing aids further flexibility to invest in the used services, rather than investing in pre-allocated packages. 


Heroku is a cloud platform-based service supporting a range of programming languages. Heroku, one of the earliest application Platform-as-a-Services (PaaS), was initially developed for writing codes compatible with Ruby programming platform (Rack).

It was first developed in June 2007, and since then, it has been in development mode. The Heroku application has evolved with time, and now, this platform supports coding languages like Java, Scala, Python, Go, Clojure, PHP, and Node.Js.

Developers have the provision to run their applications in virtual containers, also known as dynos, and then effectively execute them in a reliable environment. This serverless approach handles application archive pushes from users who are permitted to do that. Heroku allows developers to continuously deliver apps without being distracted by infrastructure.

With the help of Heroku service, developers can extend applications with Add-ons and customize them with Buildpacks. You can entrust your information to Heroku. Heroku will protect your data by performing regular audits and maintaining SOC compliance to strengthen the trust of their customers.

Azure Cloud Functions

Azure Cloud Functions is a cloud platform that provides updated resources and infrastructure needed to run mobile and web applications effortlessly. The reliable and secure Azure Functions handle infrastructure, save on cost deploy and maintain servers, while you only focus on the pieces of code.

The Azure Cloud Functions is a Function-as-a-Service (FaaS) platform that is very similar to that of Amazon’s. But they have their associated triggers and integrated services. Apart from these services, this can be a perfect alternative to AWS Lambda. 

Every application requires a path to execute codes as various events take place. Azure Functions help you meet this requirement by providing ‘compute on-demand’ facilities. This works in two remarkable ways:

First, you get the opportunity to integrate the system’s logic with the blocks of code (functions) and run the functions whenever you need to acknowledge vital events.

Second, Azure Functions meet the demands for increasing requests by deploying the functions and resources as necessary. As requests start falling, the extra applications and resources also drop off automatically.

Here lies the essence of working with a serverless approach like Azure Cloud Functions where you get access to as few or as many compute resources as you need to meet your app’s demand.

Core Features

  • Automated scaling
  • End-to-end development experience
