Microservice architecture deployed to function as a service infrastructure allows you to closely align capacity to usage, allowing you to scale up and down with ease. However when you use JVM languages the JIT warm-up time can introduce additional latency which sometimes limits which workloads this approach is suitable for. In this talk you will learn how snapshotting of Java Lambda functions is changing this entirely. You will learn how you can create a snapshot of your function after JIT compilation has been completed. So that subsequent scale ups are much faster. The talk will discuss best practices, example applications and additional resources.
