Editorial take
Why it stands out
Compare Cloudflare Workers for isolate-scale latency without VMs; compare AWS Fargate when you need every AWS service integration.
Loading
Tool profile
Run Docker VMs close to users on Anycast—strong fit for multi-region APIs, WebSockets, and stateful-ish apps with volumes and Postgres options.
Realtime collaboration servers and game backends
Fly wraps Firecracker microVMs with a CLI-first workflow: define a Dockerfile, scale regions, attach volumes, and wire private networking. It excels when latency to users matters more than hyperscaler breadth. You still operate machines—patch images, watch memory, plan failover—even though the control plane is slick.
