Java Replatforming Health Checks 1 min
Learning Goals
- To understand when to use health checks with Lambda
Lambda functions do not have health checks like you may have on container platforms. With Lambda, an invoke will come as soon as your function has initialized. It is especially important that your functions start quickly for this reason. Provisioned Concurrency and SnapStart both allow for initialization to be completed asynchronously to invokes being received.
