Top 10 Open Source Serverless Platforms

Are you looking for Open Source Serverless Platforms? Here is an in-depth tutorial explaining ten of the best serverless providers regarding features and pricing structure.

The use of open-source serverless platforms has dramatically increased in the past few years. According to a forecast by Verified Market Research, the market size of serverless architecture will reach 36.84 billion USD by 2028. Its value was only 7.29 billion USD in 2020. The major reason behind the popularity of open-source serverless platforms is their magical benefits.

Therefore, this article presents one of the top benefits of serverless platforms. This article will also discuss the dominating serverless vendors with their core features.

Benefits of Serverless Platforms

Below are some advantages of serverless computing.

Easier Deployment

An open-source serverless platform is the best option for coherent app deployment. Such a medium of app deployment is efficient and time-saving simultaneously. There will be no infrastructure construction to delay the process of application deployment. Running application on a serverless structure is relatively easy.

Additionally, developers no longer have to manage production systems to focus on the feature set of applications. This helps them to invest more time in stabilizing their applications for a better user experience.

A complete user experience compiles accessibility, convenience, and value. Now, it has become easy to provide your users with such supreme values through serverless frameworks. On that note, it is also hassle-free to ascertain identical configurations regarding the development.

Serverless frameworks have made it highly convenient to exclude any uncertain bumps when the application goes live. Developers can comprehensively test and debug the application, keeping credibility and reliability on top regarding the user experience.


Developers can cut down a significant cost of their project’s internal infrastructure by outsourcing databases. This is where serverless frameworks such as Function as a Service (FaaS) come into action. You basically aren’t responsible for data management or the server’s responsibility. In addition, these assiduous tasks can suck up great human resources too.

Setting up your own server can intermingle with your actual product goal. It will also exhaust your financial situation as a starter. Therefore, outsourcing your database and going serverless is just a supreme idea. Developers are more likely to concentrate on the actual goal cost.

This helps them achieve their business goals without keeping them in budget restraints. Anyhow, the budget requirements solely depend upon your personal case and use. So, there is no specified cost for your product case even when you ought to function serverless.

Hence, you can just try holding a complete analysis of your project details to specify your leverage over finance.

Improved Scalability

You can scale your product to a desirable elasticity with serverless frameworks. Applications that are built upon specific servers can crash or become vulnerable if user response spikes. Therefore, serverless frameworks are the best solution-call to this problem.

Besides, announcing a specific server requirement for your product’s architecture is always tricky. Nobody knew that Amazon would become this influential or popular in the consumer market. So, maximum scalability assurance is mandatory for the future of solution products.

For instance, your application is now successful after an entire year. This application under serverless support has exceptional growth potential. Serverless architectures are great at housing growth when an application’s usage is rising.

Focus on UX

It is crucial to bring a fine UX (user experience) to your application users. Your app users will indeed have no real concerns with the backend coding and app infrastructure. They will just be expecting a complete and convenient user experience.

Applications are developed to add value to the concerned audience. So they serve various possible purposes. Your application’s frontend has to be purposeful and enchanting to the audience. Developers can ingrain various feasible tweaks to bring out the best product.

They can mainly target the actual purpose an application serves. That assists developers in tailoring the efforts toward the natural purpose/goal or intent. Hence, they can provide a unified experience to the audience. Going with the best serverless framework will give you more freedom to relocate the right resources for the best user experience.

Therefore, it will help you generate more positive feedback at the end of the day.

Better Latency

In a serverless architecture, it is easy to engage users globally. They usually encompass access points on a global scale, unlike traditional servers. For instance, you are hosting a server from a specific area. A user who uses your app from another place will request signals the entire distance.

It can translate into an unavoidable delay whenever a user engages your application using a traditional server. With serverless support, there are no delays whenever users request signals using your applications. As a matter of fact, serverless nodes are present in almost every region.

On a signal request from a serverless architecture, the signal will no longer have to travel a long distance. However, serverless support can also result in a cold start. It is only when your application’s Function is dormant. You can avoid this trouble by keeping your app functions in an active state.
