High-Performance Java-Cloud-Native Apps & Microservices
summary
Shows that Java combined with GraalVM native images and modern frameworks (Micronaut/Quarkus/Helidon) produces millisecond startup, C‑like speed and small heaps; replaces JPA+Hibernate+cache with MicroStream persistence that serializes object graphs, supports lazy loading, class versioning and GC, and runs embedded or atop Oracle/MySQL/SQLite/cloud blob stores. Demo compares real app variants and reports reads and queries up to 1000x faster and a customer cutting infra costs ~90%, claiming production use.
