Operations

I believe that everything should be automated and written as code.

I use the following tools to write down the infrastructure as code and the configurations as code:

• Terraform
• Crossplane
• Ansible

As a DevOps engineer I have operated a lot of services and systems in the past. Some examples:

• Nginx
• Caddy
• Apache HTTPD
• Tomcat
• PHP-FPM
• Databases (MySQL, PostgreSQL) - with HA configurations (Galera, XtraDB Cluster)
• Redis - with HA configurations using Sentinel
• RabbitMQ
• Elasticsearch, Logstash, Kibana (ELK)
• Prometheus, Grafana
• Mercure
• and so on…
