Patch Lifecycle Management
Controlled, governed patching with rollback gates. Surprise downtime, engineered out.
Why Patching Matters More Than You Think
"We'll patch it next sprint" is the most dangerous sentence in cloud operations. Unpatched systems are the number one attack vector for breaches, and the number one cause of "it worked in staging" failures.
CloudPresto runs a governed patch lifecycle. Not a cron job that applies updates blindly, but a structured process with impact analysis, change windows, and rollback gates.
The Patch Lifecycle
Inventory & Classification
Continuous scanning of your estate. Every package, OS version, and runtime is catalogued with criticality scores and dependency maps.
Impact Analysis
Before any patch is scheduled, we map its blast radius. What services depend on this component? What's the rollback path? What's the risk of not patching?
Staged Rollout
Non-production first, then canary, then production. Each stage has acceptance criteria that must pass before proceeding. Automated validation at every gate.
Verification & Rollback
Post-patch health checks against defined baselines. If anything deviates, automated rollback triggers without waiting on a human decision.
Change Windows
Every patch deployment happens within agreed change windows. Critical security patches get expedited windows with stakeholder notification. Routine patches follow the regular cadence.
