Service Level Indicators Basics
Measure what users feel
Defining SLIs means choosing user-centered metrics like availability, latency, and correctness for key endpoints or flows, then using them to set SLOs and manage error budgets.

Pick Signals
Choose user-centric metrics per critical flow (success rate, latency).
Instrument
Measure at the edge/client; segment by region and path.
Use Budgets
Tie SLIs to SLOs and manage error budgets for releases.

Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
