There is a lot of misconception regarding — Who is a DevOps Engineer? Is he the guy who writes code and is also responsible for the work of a System Engineer? Well! Not exactly.
What is DevOps?
DevOps is a software development strategy which bridges the gap between the developers and the IT staff. With DevOps, organizations can release small features very quickly and incorporate the feedback which they receive, very quickly. Following are some other benefits:
- Fewer Software Failure
- Shortened lead time between fixes
It overcomes all the limitations of the traditional waterfall model. DevOps process involves a lot of development, testing and deployment technologies for developing automated CI/ CD pipelines. Following are some of the famous DevOps tools:
Vagrant is a DevOps tool. It allows building and managing virtual machine environments in a single workflow. It offers easy-to-use workflow and focuses on automation. Vagrant lowers development environment setup time and increases production parity.
Vagrant integrates with existing configuration management tools like Chef, Puppet, Ansible, and Salt Vagrant works seamlessly on Mac, Linux, and Window OS Create a single file for projects to describe the type of machine and software users want to install It helps DevOps team members to have an ideal development environment
