Steve Poole: JVM Support for Multitenant Applications


Per-tenant resource management can help ensure that collocated tenants peacefully share computational resources based on individual quotas. This session begins with a comparison of deployment models (shared: hardware, OS, middleware, everything) to motivate the multi-tenant approach. The main topic is an exploration of experimental data isolation and resource management primitives in IBM’s JDK that combine to help make multitenant applications smaller and more predictable. Highlights include: A fine-grained tenant API; Per-tenant resource quotas based on the JSR 284 API; Tenant-aware JRE: run existing apps in a shared JVM without code changes; Challenges: handling misbehaved tenants, safe finalization, monitoring. Filmed at JAX London 2013.
