Why should you care?

Optimization without SLOs is guesswork.

See it live — copy this example

These are architecture exercises: fill templates, draw boxes, write ADRs. No cloud bill required.

# Queue Backpressure
SLO: ...
Bottleneck hypothesis: ...
Experiment: ...

What happened?

• State SLO, hypothesis, and a cheap experiment.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Fill the template for your platform or a product you know.
2. State one trade-off explicitly (“we give up X to get Y”).
3. Draw a 5-box diagram on paper.
4. Add a failure mode.
5. Remove one unnecessary component.

Remember

You can explain Queue Backpressure simply. You captured a trade-off. You have a tiny artifact (table/diagram/ADR).
