AS7 Key Features•Fast and Lightweight (More later)•Supports domain (multi-node) management•Multiple consistent management interfaces•CLI, Java API, HTTP API, Console
•Unified, user focused configuration•No more intermixing of internal wiring and config
•Modular •Only APIs, no AS implementation exposure•True isolation (users can finally use their own XML parsers)

Two Operational ModesStandalone
•Traditional JBoss single JVM server
•Management facilities IN-VM•No lifecycle management (only shutdown)
Domain
•Multi-JVM, multi-server model
•Management coordinated by Domain Controller Process•Multiple server instances (JVMs) per Host
•Full lifecycle managed by Process Controller

Key MSC AttributesSmall, lightweight, and efficient
•216K JAR
•Tiny memory overheadHighly concurrent & scalable state machine
•State transitions are “tasks”Services are primarily interface based
•No reflection or XML required!Only two non-error, non-transition states
•UP & DOWN•N-State systems are implemented with N services

JBoss ModulesSmall, lightweight, and efficient•O(1) Dep resolution•Concurrent class loading (lockless on most VMs)•207k JAR
“Pure” modular class loading•Modules only see what they import (includes JDK classes!)
External module definitions•Don’t have to break open the JAR
Dynamic•Modules can be redefined

New Possibilities• Execute an entire Java EE container in a unit test!• Use an appserver VM per Application!• Run in constrained environments (light cloud, plug
computers, mobile devices) • Develop faster than you ever have before!• Run multiple staging servers on your laptop!
