Welcome to the Tech Garden, a place where our monitoring tools, like to diverse flora, contribute to a thriving digital ecosystem. Our journey starts with the foundational roots of Application Performance Monitoring (APM), crucial for initial growth and stability, like the roots beneath our fruit trees.

When we talk about keeping services running smoothly, we often hear about SLAs, SLOs, and SLIs. But what do these terms mean, and how are they different? SLAs, or Service Level Agreements, are like promises between a service provider and a customer. They outline what the customer can expect in terms of service quality.

It was only as I started to study information theory that I truly understood how nonsensically the computer worked in Star Trek: The Next Generation. Decades before voice assistants and at a time when only the most basic language parsing existed in practice, the computer on Star Trek could always give you the answer you wanted. No one ever spent any time clicking into multiple windows to find an answer, and the display always gave information that could be easily summarized in words.

Look, we've all been there: there's a term, you've heard it one hundred times. You've nodded as others said it in meetings. And now, you've started to say it. The only tiny insignificant problem is that you're not 100% sure what it actually means or how it's different from another similar term. I feel you. So I wrote this DevOps glossary with my highly opinionated definitions of common DevOps industry terms.

Service Mocking can accelerate dev cycles, especially as part of Internal Developer Platforms.

Every time I share a project using SaaS tools, someone inevitably responds that they could do the same thing on their own home server ‘for free.’ I mention this not because it is annoying, since I would never go on social media at all if annoying responses were allowed to change my behavior, but because I think it points to a basic misconception that still affects DevOps practitioners today: the refusal to accurately estimate the real costs of self-managed solutions.
