What is DevOps?

DevOps is a development strategy. DevOps is a development strategy for software that is used to bridge the gap between the IT staff and the developers of the software. The main advantage of DevOps is thatcompanies can release small features in a short amount of time and also incorporate the feedback that they receive quickly. Added to this, development using DevOps engineering will also result in fewer failures of software in the form of bugs. Also, the time taken to spot these errors and correct them is also reduced with this development strategy.

Who is a DevOps engineer?

A DevOps engineer does not usually code software from scratch, though a thorough knowledge of the same is required. Instead, the engineer regularly updates short bits of code to adjust the software for a better and effective experience. A DevOps engineer is equipped to manage the IT infrastructure that is required to support the code in a multi-tenant or dedicated or even hybrid cloud environment. The tasks under the DevOps development strategy may include provisioning required resources, selecting appropriate models for deployment, using the testing protocol to test the software before releases, analyzing results as well as troubleshooting any problems that may arise. In order to make these tasks easier to handle and efficiently develop software in this development model, there are a hot of DevOps engineering tools that are available for use.

What are some of the widely used tools of DevOps?

1. GIT:

Perhaps one of the most widely used tools in DevOps development strategy is GIT. There is probably no developer who has not used GIT at least once in their lifetime. GIT is essentially a control system for versions of software created by the user. It is used to track all the changes that have been made to your code. Because DevOps development mainly deals with updating code and releasing newer versions, this is a boon for engineers. GIT also helps DevOps engineers in easily coordinating the workflow with the members of their team. GIT helps engineers in a faster release cycle and also supports pull requests. One of the most important things about GIT is that it is an open-source tool that can be used for free.

2. Jenkins:

One of the most important parts of DevOps development is continuous integration. This ideal with the integration of various stages of DevOps. Jenkins is an automation tool that is open source in nature. It is written in Java and has plugins for the purpose of continuous integration. This tool can be used to build as well as test your software codes continuously, in a real-time manner. Jenkins mainly works with plugins. The community of Jenkins already has most of the tools that an engineer might require. But, in case you do not find a plugin that is suitable for your requirements, you can always build one, and if you choose to, you can share this with the community of DevOps engineers. Because Jenkins is coded in Java, integration to other major platforms will not be problematic.

3. Selenium:

Writing code is an important part of development, but testing it is also important. This is where a tool like Selenium comes into the picture. Selenium is a software that has testing frameworks for web-based applications. With Selenium you can create an easy interface to test your codes automatically. Selenium, like the other two tools mentioned above, is also open-source, meaning that you can use it for free and also change it if you need a more customized experience. You can write your scripts in multiple popular languages like Python, Java, Ruby, C#, Perl, Php, and JavaScript. Another important feature of Selenium is that it supports testing protocols for all popular platforms like android and iOS. As a DevOps development tool, you can use Selenium to crease automatic regression suites as well as tests that are browser-based.

4. Puppet:

Puppet is another popular tool that is used for DevOps development. Puppet is a configuration management tool that can help manage your servers and also automate the methods that are used for inspecting, operating, and delivering the software code written by you across the entire lifecycle along with platform independence. Another good thing about puppet is that it is also an open-source tool that has a long commercial track record with more than thirty thousand companies across the globe using it on a daily basis. Also, the puppet DevOps tool is based on the master-slave architecture that is one of the most helpful architectures for developers of DevOps related software. With this feature, you can perform dynamic scaling down as well as dynamic scaling up of your machines. The master and the slave in puppet communicate with each other through encrypted channels that are secured with the latest SSL encryption techniques.
