“Linux services are unstable or difficult to troubleshoot under production load.”
All consulting solutions
BASELINE → HARDEN → TUNE → OPERATE
Linux & Open Infrastructure
Design, review and troubleshoot Linux and open infrastructure with emphasis on reliability, security, performance and operational clarity.
Typical client situations
Recognize the problem before choosing the solution.
These are representative situations, not prerequisites for engagement.
“A platform needs hardening without breaking operational requirements.”
“A migration between distributions, hosts or infrastructure platforms is being planned.”
“Teams need an independent performance or configuration review before scaling.”
Consulting areas
