Pastries with SREs: No compromises on cost-effective observability or donuts.

Nov 12, 2025

In this episode of Pastries and SREs, we dig into how vendor lock-in and sky-high observability costs are forcing teams to choose between coverage and budget, AND why you shouldn’t have to settle.
With donuts in hand, we explore how to take back control of your observability strategy by making it cost-effective, comprehensive, and flexible.

We explore:

⦁ Real-world stories of surprise observability charges and blown budgets
⦁ Why partial instrumentation creates critical blind spots in your environment
⦁ How to manage observability costs without sacrificing data fidelity
⦁ The importance of object storage, data lakes, and full-fidelity retention
⦁ Strategies to avoid vendor lock-in and future-proof your stack
⦁ What it takes to build a platform that scales flexibly with your needs, not against them
⦁ Observability should empower your teams, not drain your budget or limit your visibility.
