You need to get a good grasp of a programming language. It doesn't matter which one, but it's needed for writing automation code. Automation is a key part of DevOps. You can learn Python, Java, Ruby, Golang etc. For this course we will be focusing on java
Having a sound understanding of the Operating System and the knowledge is always useful and here we will be having a look on the same.
Devops need to be fluent with terminal and command line as a lot of work flow is related to the terminal and a good understanding will always be better.
In this module we will be covering the multiple types of network security and protocols that devops demand an understanding of.
A server, regardless of the type, needs a robust network to give it access to the Internet and allow it to communicate with other computers. Since a server normally has exceptionally high traffic loads when compared to a normal workstation or desktop PC, it requires a network structure robust enough to prevent a bottleneck.
Docker is an open source platform for building, deploying, and managing containerized applications. Learn about containers, how they compare to VMs, and why Docker is so widely adopted and used.
Kubernetes is an open source container orchestration engine for automating deployment, scaling, and management of containerized applications. The open source project is hosted by the Cloud Native Computing Foundation
This is one of the most critical component in the learning path of a DevOps engineer. You need to learn about app containerization and have thorough understand of container tools like Docker and Kubernetes. Configuration management tools like Ansible, Chef, Salt & Puppet. Other areas include container orchestration and infrastructure provisioning.
Most of the apps today are built as cloud-native. So you need to make yourself familiar with major cloud providers. AWS, Azure and Google Cloud are the leading players and they provide free courses about their tools too.
