Lighweight VMS



Firecracker, the microVM hypervisor, is renowned for being lightweight, fast, and secure. It’s excellent for running short-lived workloads, which is why it’s the backbone of AWS Lambda.

A little-known fact about Firecracker is its lack of support for many modern hypervisor features, such as dynamic RAM management, which is vital for long-lived workloads. In this post, I will explain why Firecracker might not be the best hypervisor choice and when you should avoid it.
