AWS recently released a new type of serverless VM called Lambda MicroVMs. These can run your workload a longer amount of time than traditional Lambda functions. This means tracking CPU and memory utilization matter more. MicroVMs do not emit these metrics by default.

Next week I'm heading to my first AWS Heroes Summit in Seattle. Meeting many of the Heroes at re:Invent last year was amazing. Hanging out in person beats a Zoom call every time and I'm looking forward to spending quality time and getting to know everyone better.

Headed home today after a great AWS Summit Toronto. I got to meet so many people and am also glad I was able to do a talk. I totally agree with the sentiment that we have a "Once in a generation opportunity" right now. Just like what Werner Vogels was saying recently at re:Invent!
