Piranha Cloud - from Eclipse GlassFish to super fast Cloud and Serverless Java
summary
Piranha Cloud is a lightweight Jakarta EE runtime built from GlassFish components (Jersey, EclipseLink) with a new minimal servlet container, a modular HTTP stack and optional Hazelcast session extension. Measured startup times: GlassFish ~4.1s, plain Java main 60ms, Piranha embedded + HTTP 237ms, minimal embedded 150ms; a realistic Jersey REST stack runs near 1s. Piranha runs as an embeddable library, packages features as separate Maven artifacts, and maps cloud events for AWS Lambda, enabling fast cold starts while keeping standard Jakarta APIs.
