Docker launched in 2013 promising simplicity: package once, run anywhere. Containers were lighter than VMs, more portable, more efficient. Infrastructure teams adopted them fast.
Then came the math. Containers last 2.5 days on average. VMs? Nearly 15 days. That order-of-magnitude difference means your infrastructure now churns through dozens or hundreds of workloads where you once managed a handful. Each one needs security monitoring, health checks, resource tracking, orchestration.
The feature that made containers attractive created the problem. Lightweight and ephemeral by design.
Your monitoring strategy can't assume infrastructure stays still long enough to investigate. Ephemerality isn't a deployment phase. It's the operating model.
