This formation will teach you the basics. DevOps is a way of collaborating between development teams and production operators. It reduces frustration between these groups by enabling common standards, unloading repetitive and tedious tasks to automation and accelerating the time-to-production in a more stable way.

Goals

  • Automate the release to production in a quick, reliable and repeatable way
  • Standardize codes and infrastructures in order to facilite communication between teams and team members
  • Increase quality by testing applications and infrastructures before production

Targeted audience

  • Developers
  • Sysadmins
  • Networkadmins
  • Software architects
  • Software agile teams

Requirements

  • Basic knowledge of programmation
  • Basic knowledge of system/network administration

Special features of this formation

  • Everything opensource: every tool we use is opensource. So it’s easier to replicate what you learn directly into your own project
  • Quick theory-practice cycle: each theoretical point is linked to a practical exercise. You learn faster when you put directly into practice what has just been taught
