Infrastructure as Code and Linux server administration
Linux servers under control, infrastructure from configuration in Git, monitoring, backups and protection
I administer GNU/Linux and build infrastructure as code: Docker and Docker Compose, Nginx and PM2, CI/CD (build and delivery), deployment. I set up Zabbix and ELK (Elasticsearch) monitoring, backups and failover, and DDoS protection, from a single server to a multi-service platform
What is included

02
Infrastructure as code
Docker, Docker Compose and environment configuration versioned in Git
- Docker and Docker Compose
- Environments described by configuration in Git
- Reproducible deployment to staging and production
- CI/CD: build, checks, delivery
03
Monitoring and backups
Zabbix and ELK, alerts, backups and recovery checks
- Zabbix monitoring: metrics and alerts
- Logs and search across them in ELK
- Scheduled backups
- Recovery checks from backups

Common questions
How does server administration differ from infrastructure as code?
Administration is setting up and running live servers. IaC describes environments as configuration in Git, so the environment is reproducible instead of assembled by hand
Can you take over a server that is already running?
Yes. I start with an inventory of servers, services, access and backups, then fix the failure points and the work plan
How does a cloud migration work?
First an audit of the current setup and its dependencies, then the target diagram and the move of data and services, followed by scenario checks after the migration
What is included in support?
Zabbix and ELK monitoring, alerts, backups with recovery checks, updates and DDoS protection
