Serverless computing involves using backend-as-a-service (BaaS) and function-as-a-service (FaaS) to enable autoscaling and usage-based pricing.
Knative provides a serverless abstraction on any Kubernetes cluster, enabling features like scale-to-zero, blue-green deployments, and event-driven architectures.
A standard Spring Boot application deployed on Knative demonstrates slow startup times and high memory consumption, highlighting areas for performance improvement.
Ahead-of-time (AOT) compilation with GraalVM creates native images that offer faster startup and lower memory usage compared to traditional just-in-time (JIT) compilation.
Building a native image involves a lengthy compilation process and requires explicit configuration for dynamic features like reflection, which can be generated using the GraalVM agent.
The Spring Native project simplifies building GraalVM native images by providing an AOT plugin and annotations to handle dynamic features without code changes.
A Spring application compiled to a native image shows dramatic improvements on a serverless runtime, with startup time reduced from seconds to milliseconds and memory usage cut by nearly 90%.
