AWS re:Invent has been taking place this past week in Las Vegas, as such we've got plenty of serverless related updates to share. So yup, it's an AWS-heavy issue this week with lots to check out and get up to speed on. Let's get to it.

Accelerate Your (Java) Lambda Functions with Lambda SnapStart — One of the biggest announcements was aimed at Java developers (for now) with a claim of up to 10x faster startup performance by caching the state of a function just after initialization and then reloading that state at runtime. This post shows off how it works in practice, whilst 'Serverless Sam' shares six things to keep in mind before jumping in. We're likely to see this idea branch out to other runtimes in due course, though Java apps will particularly feel the benefit given their start-up times.

As with Neptune, there has been some discussion over just how 'serverless' OpenSearch Serverless is, given its minimum billing requirements. Ben Kehoe makes the observation that "serverless" mostly means "autoscaling" in this case.
