In recent years there have been tremendous technological changes and acceptance notified in the IT field. A growing number of companies are adopting new technology. The Development and operational changes have to lead to a new stream of DevOps practices. Let’s begin and explore the DevOps journey.
What is DevOps?
Well...DevOps is the mash-up of Development and Operations. It is a method of managing the full application development life cycle, including development, testing, deployment, and operations, by a single team.
DevOps is a term that combines two words: development and operations. DevOps is a method of managing the full application development life cycle, including development, testing, deployment, and operations, by a single team. The goal of DevOps is to shorten the development life cycle of a system while providing features, repairs, and updates regularly that are closely aligned with business goals. DevOps is a software development process that allows for the rapid and reliable development of high-quality software. Continuous development, continuous integration, continuous testing, continuous deployment, and continuous monitoring are some of the steps.
Now that you know what is DevOps, let's have a look at why DevOps matters with the help of an example:
When thinking of an example, you can consider Netflix! Yes, Netflix is a fantastic example of DevOps. Their DevOps culture has enabled them to innovate faster, leading to many business benefits. It also helped them achieve near-perfect uptime, push new features faster to the users, and increase their subscribers and streaming hours. The automation in Netflix is all defined by DevOps. So, hope you understood how DevOps is making things better for us.
Popular DevOps Tools
To get a successful DevOps transformation, there are certain DevOps tools, some of which are mentioned below:
Version Control Tool
Version control tracks all the code and programming updates and changes. Such that in case of data loss or code error the previous version of the code can be retrieved. So, It is a tool that takes care of program backup.
GIT is a tool that allows you to track changes in your file and, by using it you can easily coordinate the work among your team. Before Git was introduced, Developers mostly submit their codes to the central server without having their copies. If they made any changes in the source code, it was unknown to the other developers. Also, there was no communication between any of the developers. But Git solved these all. Through GIT, every developer can have an entire copy of the code on their local systems. Moreover, any changes made to the source code can be tracked by others. There is regular communication between the developers. Even they can undo the changes made in the code.
If we look at the features:
GIT is a Free Open source Tool, it allows distributed Development. It even supports pull requests and enables a faster release cycle.
Microsoft, Amazon, Facebook, and LinkedIn, are some of the companies using GIT.
The next tool we have is the Build tool:
Maven is a DevOps tool used for building projects. It is also designed to manage reporting, documentation, distribution, releases, and dependencies processes. Projects written in Java or C++, Ruby, and Scala are managed by Maven.
Maven features include:
The project setup is simple and follows best practices.
It is used in almost all projects.
Reliable and dependable in project management.
Another most used tool is,
Configuration management tool:
Configuration management refers to the maintenance and control of the components of a complex system. IT components may include networks, servers, storage, and applications.
The next tool is,
Chef is an open-source framework that has multi-platform support which includes the cloud. Chef is a popular DevOps tool. Chef is a powerful automation tool that enables developers to transform infrastructure into code. Starting from deploying, repairing, and updating to managing servers and applications in any environment, Chef can do it all.
It can also be integrated with cloud platforms like AWS, Google Cloud Platform, Open Stack, etc.
If we look into the features,
A chef can easily manage hundreds of servers with a handful of employees.
It maintains a blueprint of the entire infrastructure.
Moreover, it supports large deployments.
Now, to implement DevOps practices, DevOps Engineer comes into the picture.
