What is DevOps?
DevOps is a set of practices that works to automate and integrate the processes between software development and IT teams, so they can build, test, and release software faster and more reliably.
Plan →Build →Test →Debug →Deploy →Monitor →Audit →Diagnose → Tune → Feedback → Analyze → Edit →Build
There are lots of tools available in the market :
Here we will talk about Top DevOps Tools that you can choose and start learning.
Docker is a set of the platform as service products that use OS-level virtualization to deliver software in packages called containers.
What are the containers?
A Docker container can be seen as a computer inside your computer but the cool thing about Docker is you can share it with your friends Let’s understand it with an example:-
Imagine that you are working on some project let’s call it TestingO1 when you tested that code it gives you O.P. as 4.3.1 Now you send that code to your friend and he runs the same code but he got output as 4.2.9 here’s we are just talking about numbers but in real life, you can imagine what problems you face. The reason behind that such as os change or maybe library version change it could be many things.
With the help of Doker, it allows us to wrangle dependencies starting from the operating system up to details such as Package version, etc it makes sure that your analyses are reproducible and the same.
Kubernetes is an open-source container orchestration platform that enables the operation of an elastic web server framework for cloud applications.
Kubernetes features the ability to automate web server provisioning according to the level of web traffic in production.
Reasons to Love Kubernetes:-
- Kubernetes helps you move faster
- Cloud agnostic
- Cloud providers will manage Kubernetes for you
DevOps teams can streamline containers in a cluster with the help of Kubernetes. It can even help them to effectively monitor the containers. Kubernetes is a complex system compared to other DevOps tools. But it helps users to easily troubleshoot the problem, and execute commands.
Ansible is a simple yet powerful server and configuration management tool, that can transform the DevOps of an organization by modernizing IT and enabling faster deployment of applications.
Ansible automates IT requirements such as application deployment, cloud provisioning, and container orchestration.
Ansible fits into multiple areas of cloud-native infrastructure management, but I would like to specifically highlight three areas
The different between Ansible and other tools is that it is used only for configuration deployment. Ansible is much simpler compared to other DevOps tools.
