Why is the DevOps Engineer Job a Challenge?

The main function of a DevOps engineer is to introduce continuous delivery and continuous integration workflow, which requires understanding the previously mentioned tools as well as several programming languages. But, there are also several other responsibilities:

  • Writing specifications and documentation for server-side features

  • Management of continuous deployment and continuous integration (CI/CD)

  • CI/CD script writing

  • Performance assessment and monitoring

And, DevOps usually comes with the responsibility of on-call support shared among the team. Since the service should provide 24/7 operational support, a DevOps engineer job may come with even more challenges.
