Tools used in DevOps methodology

In this blog, we will discuss the tools that are used in DevOps. As we have already learnt that DevOps is a software development approach that emphasizes collaboration and communication between software developers and IT operations professionals. This approach aims to shorten the development life cycle and provide continuous delivery of high-quality software. To achieve these goals, DevOps teams often use a variety of tools to automate the process of software development and deployment.

Some common tools used in DevOps include:

Version control tools, such as Git, allow teams to manage and track changes to their codebase, Continuous integration and continuous delivery (CI/CD) tools, such as Jenkins, which automate the process of building, testing, and deploying software. Configuration management tools, such as Ansible and Puppet, which help teams manage and automate the configuration of their infrastructure Monitoring and logging tools, such as Splunk and New Relic, which provide real-time visibility into the performance and health of an application These tools can help DevOps teams automate many of the tasks involved in the software development process, such as building, testing, and deploying code, as well as managing and scaling infrastructure. This can help teams release high-quality software faster and more reliably.

1. Version controlling

Version control is a system that allows developers to track and manage changes made to a project's codebase. This allows developers to collaborate on a project without overwriting each other's work and allows them to revert to previous versions if needed.

Purpose of Version Control Systems:

  1. Multiple people can work simultaneously on a single project. Everyone works on and edits their own copy of the files and it is up to them when they wish to share the changes made by them with the rest of the team.

  2. It also enables one person to use multiple computers to work on a project, so it is valuable even if you are working by yourself.

  3. It allows for easy management of multiple versions of a project, so that different versions can be worked on concurrently without interfering with each other.

  4. It allows for easy management of multiple versions of a project, so that different versions can be worked on concurrently without interfering with each other.

There are several types of version control systems, including:

  1. Centralized version control systems: In this type of system, there is a central repository where all the code is stored and managed. Developers must connect to this repository to access the code and make changes.

  2. Distributed version control systems: In this type of system, each developer has their own local copy of the codebase. Changes are made to the local copy and can be shared with other developers through synchronization.

Centralized version control systems vs Distributed Version control systems: The Comparision

In a centralized version control system, there is a central repository where all versions of the software are stored, and developers must "check out" a version of the code from the repository, make changes, and then "check in" the updated version. This central repository is the single source of truth for the code, and all changes to the code must be coordinated through it.

In a distributed version control system, on the other hand, there is no central repository. Instead, each developer has a local copy of the entire codebase, and they can commit changes to their local copy without having to coordinate with other developers. This allows for more flexibility, as developers can work on their own copies of the code without being connected to a central server. When they want to share their changes with other developers, they can push their local changes to a remote repository, which acts as a shared source of truth for the code.

One of the most popular distributed version control systems is Git. Each developer has a local copy of the project's codebase, which they can make changes to without affecting the main codebase.

Using Git, developers can create branches of the codebase to make changes to without affecting the main branch. This allows developers to work on multiple features simultaneously without interfering with each other's work.

Once a developer has made changes to their branch, they can submit a pull request to merge their changes with the main branch. This allows the other developers to review the changes and make sure they are ready to be integrated into the main code base.

Git also allows developers to create tags, which are specific versions of the codebase that can be referred to later. This is useful for creating versions of the codebase for release, or for reverting to previous versions if needed.

Overall, version control is an essential tool for developers working on collaborative projects. It allows them to track and manage changes to the codebase, collaborate with other developers, and easily revert to previous versions if needed. Using Git, developers can take advantage of its powerful features to manage their codebase effectively.
