DevOps (Development Operations) and MLOps (Machine Learning Operations) are almost the same and share a wide variety of tools. As a DevOps engineer, you will deploy, maintain, and monitor applications, whereas as an MLOps engineer, you deploy, manage, and motor manufacturing models into production. So, it is beneficial to learn about DevOps tools as it opens a wide array of job opportunities for you. DevOps refers to a set of practices and tools designed to increase a company's ability to deliver applications and services faster and more efficiently than traditional software development processes. 

In this blog, you will learn about essential and popular tools for versioning, CI/CD, testing, automation, containerization, workflow orchestration, cloud, IT management, and monitoring applications in production. 


1. Git


Git is the backbone of modern software development. It is a distributed version control tool that allows multiple developers to work on the same codebase without interfering with each other. Understanding Git is fundamental if you are getting started with software development.
