Running Your Own Cluster Is Now Simpler Than Believing in PaaS

Description and use

Running your own cluster with an AI assistant is now simpler and cheaper than PaaS promises, given recent outages and rising cloud costs.

Problem

Teams rely on PaaS to avoid ops, but outages, cost, and vendor lock‑in undermine the promised simplicity, reliability, and savings.

Outcome

Self‑hosting with AI assistance can match or beat PaaS in cost, reliability, and control, while freeing teams from vendor‑specific ops burdens.

Workflow

• 1. Assess FinOps and ops staff count
• 2. Identify fixes possible during vendor outages
• 3. Price equivalent stack on plain VMs
• 4. Verify backup ownership and location
• 5. Review recent vendor outage reports
• 6. Deploy a throwaway cluster with an AI agent over a weekend
• 7. Retain managed services only for compliance, on‑call, or burst traffic
