Episode notes
ECS Dominates New Container Workloads
- Amazon ECS is a fully managed container orchestration service that schedules containers on serverless or EC2 compute.
- Over 65% of new AWS container customers choose ECS and it launches ~3 billion tasks weekly.
Fargate Removes Host Management
- Fargate is a serverless compute engine that removes OS and instance management from customers.
- You pay per task runtime, avoiding idle-instance costs common with EC2.
Customers Need EC2 Flexibility With Management
- Some workloads require specific instance types, GPUs, or high network throughput that Fargate's general compute doesn't provide.
- Those customers wanted managed benefits (like OS patching) while retaining EC2 flexibility.
