Platform Architecture / OpenShift / Kubernetes / F5
Reliable platform architecture for enterprise infrastructure.
Perseus Administration is an independent platform and infrastructure architecture practice led by Przemysław Bielawski, focused on OpenShift, Kubernetes, GKE, F5, Linux automation and reliable systems that need to operate under real enterprise constraints.

Architecture Notes
Writing about platforms that need to remain operable.
Practical notes about platform engineering, infrastructure architecture, reliability and enterprise operations.
Platform reliability starts with operability
Reliable platforms are not defined only by architecture diagrams. They are defined by the ability of real teams to operate, recover and evolve them under pressure.

Approach
Architecture should be practical, resilient and explainable.
Perseus Administration focuses on the operational consequences of technology decisions: reliability, maintainability, automation and the ability of real teams to support systems over time.
Architecture grounded in operations
Decisions are evaluated not only by how they look on diagrams, but by how reliably teams can operate them.
Reliability before unnecessary complexity
The goal is not to add layers of technology. The goal is to make critical systems maintainable and resilient.
Enterprise-aware pragmatism
Platform decisions have to survive real constraints: legacy systems, security requirements and operational pressure.
