Achieving genuine elastic multitenancy with the Waratek Cloud VM for Java : John Matthew Holt

  2. 2. !!!Achieving genuine elastic multitenancy !for Java applications with the WaratekCloud VM for Java! © Copyright 2012
  3. 3. The Problem with Java!•  Java is 15 years old, predates multitenant cloud computing•  JavaEE app servers were designed to host multiple webapps, but rarely do in practice because theres no isolation between webapps•  Todays JavaSE/JavaEE apps are deployed as "one app per app-server per JVM", which leads to "app-server sprawl”•  Hosting one webapp per JVM means provisioning fixed cpu/ memory quotas which cant elastically fluctuate on demand. © Copyright 2012
  4. 4. The Problem with Java!•  Hosting one webapp per fixed cpu/memory quota means there is unused cpu/memory capacity being paid for: this is a waste•  Todays JavaSE/JavaEE apps are perfectly suited to a multitenant "pay exactly what you consume" model were there a multitenant JVM•  A multitenant JVM would be able to charge computing power like a utility: gigahertz-hours for cpu, gigabyte-hours for memory © Copyright 2012
  5. 5. Virtualizing the Java Platform!•  The Waratek Cloud VM introduces a feature called Java Virtualization Containers (JVC)•  A JVC is a metacircular VM within the JVM which shares the host JVM environment (heap, classes, JIT) with other JVCs•  A JVC is extremely lightweight: < 1 MB overhead per JVC JVC 1! JVC 2! JVC 3! Waratek Cloud VM for Java! © Copyright 2012
  6. 6. Fine-grained resource control!•  A single VM can host thousands of JVCs: a JVC can be any size (from 1MB up to many GBs)•  Every aspect of JVC execution is isolated: cpu priority, memory limits, bandwidth, etc•  Every aspect of JVC use is metered: cpu use in Hz, memory/IO use in Bytes•  JVCs provide computing power like electricity kW-h: cpu consumed in GHz-h, memory consumed in GB-h © Copyright 2012
  7. 7. Waratek Cloud VM delivers Java-as-a-Service!•  Run JavaSE/JavaEE platform software as a multitenant cloud service without code change: binary compatible with existing apps and platforms•  Every .war/.ear/.jar app gets its own JVC .war app! .ear app! .jar app! Tomcat / JBoss / GlassFish / Other ! Waratek Cloud VM for Java! © Copyright 2012
  8. 8. Extensible Java Virtualization!•  JVC framework is fully extensible and customizable: enhanced JVCs can be created by anyone using Waratek APIs•  Special-purpose JVCs already in dev or planning: Servlet JVCs for Tomcat, EAR JVCs for JBoss, Scala JVC, Clojure JVC, et al•  Waratek is adding a range of premium JVC features: legacy JVCs, live snapshot, live migration, JVC mirroring for disaster-recovery, etc. © Copyright 2012
