What you can do when a more dynamic approach to infrastructure-as-code is necessary — Dynamic Resource Provisioning In the past, infrastructure setup and maintenance were often done manually and on the fly.

It’s a matter of when, not if things will happen. Better be prepared. — What if, despite all safety measures like advanced configurations, asymmetric cryptography, and port knocking, an attacker gains access to one of my cloud servers?

Part 1: Into the unknown with a GitOps approach — New year, new challenges Although it's technically not different from a non-production deployment, production changes are definitely less fun. What's clear is, the fewer environments we have, the easier it is to manage them, and therefore, the less overall risk is involved. Being based mainly in Germany with branches in Thailand and India, we…
