[Verse 1]
When systems crash and users complain
We need a plan to handle the pain
SLAs promise what we'll deliver
SLOs set the goals that make us shiver
SLIs measure what's really true
Are we meeting promises we made to you?
[Chorus]
Build it strong, make it last
Learn from failures of the past
Error budgets, chaos days
Reliability always pays
Logs and metrics, traces too
Observability pulls us through
[Verse 2]
Error budgets tell us how much we can fail
Before the business starts to wail
When the budget's spent and gone away
Time to slow down, fix things today
Cascading failures bring systems down
Thundering herds crash the whole town
[Chorus]
Build it strong, make it last
Learn from failures of the past
Error budgets, chaos days
Reliability always pays
Logs and metrics, traces too
Observability pulls us through
[Verse 3]
Split brain syndrome tears apart
Distributed systems at the heart
Chaos engineering shows us how
To break things safely here and now
Chaos Monkey kills your code
GameDay tests the rocky road
[Bridge]
RPO and RTO define
How much data loss is fine
Active-active, active-passive too
Disaster recovery pulls us through
Feature flags shed the load
When traffic breaks our code
[Verse 4]
Graceful degradation saves the day
When everything starts to fray
Incident management keeps us sane
Severity levels ease the pain
Blameless postmortems teach us why
Learning helps our systems fly
[Final Chorus]
Build it strong, make it last
Learn from failures of the past
Error budgets, chaos days
Reliability always pays
OpenTelemetry shows the way
Resilient systems here to stay
[Outro]
Three pillars standing tall and bright
Logs and metrics, traces in sight
SLO dashboards guide us home
Never let our systems roam
