Top 10 FaaS Providers

The utilization of Function as a Service (FaaS) is rapidly increasing among developers and businesses in the last few years. A MarketsandMarkets study forecasts that the market size of FaaS would reach around 7.72 Billion USD in 2021.

This shows the demand for FaaS features and providers in the cloud computing world. That’s why this guide is sharing top FaaS providers and advantages with readers.

What is FaaS — Function as a Service

Without managing the infrastructure, this serverless model of cloud computing permits developers to make, operate and scale applications as functions.

Function as a Service (FaaS) installs functionalities and only costs when these functionalities are accomplished. In short, FaaS gives developers an opportunity to run a component of an application or a separate function but only charges when the script is acted out.

Conventionally, FaaS is used to set up microservices. AWS Lambda, OpenFaaS, Google Cloud Functions, IBM Cloud Functions and Microsoft Azure Functions are famous FaaS providers.

Advantages of Function as a Service

Function as a Service is popular among developers and businesses because of distinct benefits. However, we are discussing the major advantages of using the FaaS platform here:

Enhances Development Speed

With Function as a Service (FaaS) developers don’t need to worry about the deployments and servers. They just need to emphasize the code because the server is parted into functions. This feature leads to independent scalability. Also, you don’t have to administer the infrastructure with FaaS. Therefore, this cloud computing model doesn’t only enhance the development speed of your project but also overcomes the time to market your application.


Although FaaS permits developers to only pay when the script is executed, but it is also inexpensive in many ways. Yes, most of the FaaS providers offer pay-as-you-go pricing models where customers only have to pay for what they use. It means you don’t have to pay for anything extra with FaaS.


Scalability is another great benefit of using FaaS platforms. Indeed, FaaS vendors scale up the functions instantaneously when it is needed and also reduce them according to the requirements. In simple words, it is seamless to scale your application automatically with FaaS models.

Reduces Delays

The servers of different FaaS providers are spread in various geographical zones. That’s why developers don’t need to face delays. This benefit of FaaS definitely overcomes the development latencies.
