DevOps focuses on bringing all the development, operations, and IT infrastructure persons including Developers, System Admins, Testers, and QAs into one single team. All those team members together called DevOps Engineer. DevOps is a software development strategy that bridges the gap between the IT department and developers. With the help of DevOps training in hyderabad, organizations are able to release small features and incorporate the feedback which they receive very quickly. Some more benefits of DevOps are:

  • Less Software Failure
  • Shortened Lead Time between fixes 

DevOps Tools:

It overcomes all types of limitations of the traditional waterfall model. DevOps process includes lots of development, testing, and deployment technologies to develop CI/CD pipelines. Given below some of the popular DevOps tools :

  • Jenkins: Automation Server with plugins built for developing CI/CD pipelines
  • Git and GitHub: Source Code Management (Version Control System)
  • Nagios: Continuous Monitoring
  • Chef:  Configuration Management and Deployment
  • Kubernetes: Containers Orchestration tool
  • Docker: Software Containerization Platform
  • Ansible: Configuration Management and Deployment
  • Selenium: Automation Testing
  • Puppet: Configuration Management and Deployment

DevOps Engineer:

 DevOps Engineer would able to understand the Software Development Lifecycle along with an outright understanding of different automation tools to develop Digital Pipelines like CI/CD pipelines. DevOps Engineers are working with developers and the IT staff to manage the code releases. They are either developers who get interested in operation and networking operations or system admin with a passion for coding and scripting and able to move towards the development side where they can improve the planning of test and deployment.

Continuous integration and Continuous Development (CI and CD): Knowledge of different tools of DevOps is not enough to work on it. You should know where to use these tools.  Such tools are being used to facilitate Continuous Integration and Continuous Delivery and even in Continuous Deployment in some cases as well. However, continuous Deployment is not at all considered a good practice.

Infrastructure as Code (IAC): Infrastructure as Code or IAC is a type of IT infrastructure that can be automatically managed by the operation teams and provision through code rather than using any manual process. IAC is sometimes known as Programmable Infrastructure. With the advanced technology of IAC, the gap between the developer and the System Operating Persons is decreased.
