This simplified diagram summarizes my end of POEI DevOps training project.
On behalf of a small fictitious company, it was necessary: ​​

• Set up Linux servers (Ubuntu, CentOS, etc.) to host company services. (Blogs, Gitlab, etc.)
• Implement monitoring solutions to monitor the status of virtual machines, containers, networks, servers, etc., and receive alerts in the event of a problem. (Prometheus Grafana Stack)
• Priorize the use of Docker for the deployment of services.
• Priorize the use of Ansible for server configuration.

Another part of the project, which you will find at the bottom right, focuses more on Windows administration and the following tasks:

• Networking
• Scripting
• Management of GPOs, users and AD
