An Overview of Fission Framework

If you are familiar with Cloud Computing or dealing with Servers, you might have heard the term “Fission Framework.” While this term is tossed around often, people do not know the full concept behind it.

“Fission Framework” holds a significant value in the field due to its vast usage. However, if you are unfamiliar with it, there’s no need to worry! This guide will cover everything you need to know about Fission.

Everything You Need to Know About Fission Framework

What is Serverless Framework on Kubernetes?? A Serverless Framework on Kubernetes basically means that you do not need a server and infrastructure to run your applications. It lets you deploy functions without worrying about the underlying infrastructure.?The main benefit of Serverless Framework is that it offers cluster-free working. It reduces repetitive configuration in a cloud provider-independent way.?Fission is the Kubernetes-native framework that allows you to code functions in the most popular languages.

Why do we Need to Use the Fission Framework??

What makes Fission Framework stand out among the others? It gives you maximum convenience by allowing you to code serverless functions. And that’s not it!?You can run these functions wherever you have a Kubernetes Cluster. It can be a public cloud, your device, on-premises, or at the Edge. ?Another benefit is that you only focus on the code while working with Fission. That’s because it automatically manages the infrastructure for you.

It is the open-source Kubernetes-native for Serverless functions. It falls under the category of FaaS (Function-as-a-Service).

Fission Framework Architecture

?Fission is designed as a collection of microservices. It has a central piece, known as the “Controller,” which keeps track of the functions. The Pool Manager manages the idle environment containers, while the Router receives HTTP requests and sends them to function instances. ?When the router receives a request, it looks into a cache to see if the request already has a service to route to. If there are none, it looks up the function to route the request. ?The PoolManager picks an instance and loads the function into it. It returns the address to the router, which proxies over the request. ?The Router is divided into two “Specific Function Pods.” Similarly, the Pool Manager has a pool of idle pods. ?Fission enables the easy deployment of Serverless functions. These functions execute discrete tasks. They are also used to deploy simple applications.

Fission Framework Features

• Low Cold-Start Latency? - Fission maintains a pool of containers, so functions have very low cold-start latencies.
• Declarative Specifications? - Using Declarative Specifications, you can define a function once and deploy it anywhere.
• Simple Operations and Administration? - Fission offers operational simplicity as it incorporates logs directly into the CL, thanks to its integration with Fluentd.
• Istio Integrated - Fission integrates with Istio to manage microservices with ease.
• Wide Language Support - ?Fission supports various programming languages, including NodeJS, Go, C#, PHP, and Python.

Conclusion?

And, that brings us to this detailed overview of the Fission Framework. I have covered what it is, how it works, and its features. This guide will help you understand all the relevant aspects of the Kubernetes-Native Serverless Framework and next I'll bring an article with some hands on.
