Linux

Our team used to create several virtual machines per day and configure them manually. This process consumed several hours of work each day. I took the initiative to automate the provisioning of VMs using Ansible, including their configuration. To support this, I developed a standardized server configuration and trained the team, so that everyone could independently create and configure new servers using Ansible.

At the time, around 40 virtual Debian servers were managed and maintained manually. I took the initiative to introduce Salt into the environment to manage the servers more efficiently and standardize their configurations. Today, the client reports that the setup is still in use and actively being developed further.

At the time, around 50 virtual Linux and Windows servers were being operated without any centralized monitoring system. Service outages and disruptions were only reported by end users, often resulting in prolonged downtimes. I introduced Icinga2 - a monitoring solution compatible with both Linux and Windows. Existing and new Linux servers managed via Salt were automatically integrated into Icinga2, with service checks applied accordingly. This enabled the team to detect and respond to outages much faster and more professionally. Today, the client reports that the setup is still in use and actively being further developed.
