61. Cost vs availability trade-offs
How higher availability choices (multi-AZ/region, warm pools) impact cost and capacity planning.
Infrastructure as Code / AWS (Terraform & CloudFormation)
Cost vs availability trade-offs
Choosing higher availability means spending more money to reserve extra capacity and duplicate infrastructure so services keep running during failures.
"I want my app to stay up even if a whole data center fails, but I also need to stop the bill from exploding."
Higher availability uses redundancy (extra instances, AZs, regions, warm pools) to reduce outage risk; each layer of redundancy increases infrastructure and operational cost and changes capacity planning.
