What does a DevOps Engineer do?
DevOps specialists are mainly those programmers who are interested not only in writing code, but also in releasing it; code production.
DevOps specialists are involved in the creation, testing, production and release of products.
DevOps is a set of practical application development methods consisting of Software development (Dev) and IT operations(Ops).
DevOps engineers ensure fast and secure server deployment, security, and create precautions in case of server failure and hacker attack.

- Jenkins – a CI/CD server with an open source that automates various stages of the software.It is widely distributed, as it has a large number of plugins, thanks to which you can use it with other DevOps tools. Works with Linux, Windows and Mac OS systems.
- Bamboo – a CI/CD server solution from Atlassiann, which is somewhat similar to Jenkins. Works with Bitbucket and Jira.
