Reliability

Chaos Engineering
Chaos Engineering is a practice of safely injecting failures into a system to observe its behavior and improve reliability.
Reliability
Error Budget
The allowed amount of downtime or errors a service can have and still hit its reliability target (SLO).
Reliability
Incident Management
Coordinated way to detect, prioritize, fix, and learn from service outages or other unplanned problems so systems get back to normal fast.
Reliability
Service Level Agreement (SLA)
A contract that defines expected service uptime, performance, and support response times between a provider and a customer.
Reliability
Service Level Objective (SLO)
A measurable target for how reliably or fast a service should work over a set time period.
Reliability
SRE (Site Reliability Engineering)
Using software engineering to keep production services reliable, available, and fast.
Reliability
Dead Letter Queue (DLQ)
Dead Letter Queue (DLQ) is a queue for failed messages, used to isolate errors for later retry or inspection.
Reliability
Circuit Breaker
Circuit Breaker is a pattern that pauses calls to failing services to reduce cascading failures during outages.
Reliability
gRPC Deadline
A gRPC deadline is a per-RPC time limit that tells services when to stop waiting and fail the request.
Reliability
Uptime
The percentage of time a system or service is up, running, and available to users.
