Spot Instances
summary
Amazon EC2 Spot Instances cut compute costs drastically — up to 90% and 70–75% average savings for many customers — and work with Jenkins CI/CD by using Spot Fleet / EC2 Fleet or Auto Scaling mixed-instance policies to diversify across sizes, families and AZs. Use capacity-optimized allocation and the two-minute warning to detach from load balancers or requeue builds (checkpointing rarely fits). A Jenkins plugin ties the master to Spot Fleet, auto-replaces interrupted workers with maintain-capacity, and the demo registers and runs agents successfully.
