In today’s rapidly changing digital landscape, the deployment of applications is becoming more challenging than ever before.

As businesses are embracing digital transformation, it’s crucial to choose the right infrastructure to host your application, and two options that have gained popularity are Kubernetes and Serverless. Both have their strengths and weaknesses and choosing between them can be a difficult decision.

In this article, we’ll explore the differences between Kubernetes and Serverless computing, and provide some guidance on which approach is best suited for different types of applications.

Firstly let us understand both concepts in brief so that first-time readers can get some high-level ideas.

Brief Introduction

Kubernetes — is a container orchestration system that allows developers to deploy and manage containerized applications at scale.

It provides a framework for automating the deployment, scaling, and management of containerized applications, making it easier to manage large, complex systems.

It has a master and worker-based architecture and several components like Deployments, Pods, Services, Ingress, Volumes, etc that makes it very much effective for the new age microservices-based deployment.

Serverless computing, on the other hand, is a model where developers write and deploy code without having to worry about the underlying infrastructure.

The cloud provider manages the infrastructure and automatically scales resources up or down based on the demand for the application. Serverless computing is often used for event-driven applications, where code is triggered by specific events, such as user actions or changes in a database.

AWS has Lambda, Google has CloudFunctions, and Mircosoft has Azure Functions, in a similar manner various cloud providers have their own serverless service available.
