The Abstraction Tax: Single-Threaded Workloads on Fargate

Cloud abstractions like Fargate can hide CPU constraints that devastate single-threaded workloads, making legacy migrations risky without detailed performance profiling. This case demonstrates how aggregate metrics can mask single-core bottlenecks, resulting in 10x latency increases despite apparent idle capacity. Organizations must understand workload threading models during cloud modernization, not just infrastructure topology.
