AS7 in a nutshell

AS7 in a nutshell (seriosly)

●Blazingly fast (<3s startup)●Lightweight●Modular core●Hot, parallel deployment●Elegant administration●Domain management●Easy testable

Boot time

Memory

Core rewritten from scratch to achive..

● Improved usability, increased manageability, simplified configuration

● Domain management● Multiple consistent management interfaces

● CLI, Java API, HTTP API, Console● Unified user-focused configuration● Modular

● Only API – no implementation details● True isolation

Simplified user-focused configuration

Standalone mode

● Standalone is a single AS process for use in development, where the additional management functionality is not required

● Provides a similar development experience to previous versions of the JBoss AS, allowing a deployment to be dropped in a folder and automatically be deployed

● Same management tools and APIs as domain mode

Domain mode

● Easy management of multiple JBoss AS instances

● Managed from a single point, all have access to the same domain configuration

● Allows for management and configuration updates to be pushed out to all servers

● Domain mode has three separate processes● Process Controller● Host Controller● Server instance

Domain processes

● Process Controller● Responsible for managing, starting / stopping

processes● Extremely simple

● Host Controller● One host controller is the domain controller,

the rest are slaves● Domain controller responsible for pushing

management and configuration changes

Domain mode

Demos

● Booting standalone mode● Booting domain mode

Architecture

JBoss Modules

● New classloading project● Provides a modular (not hierarchical)

classloading environment● Classloading is extremely fast● Classloading is truely isolated by default● Classloading is extremely flexible

Hierarchical classloading

Modular classloading

JBoss Modules

● Fast● O(1) dependency resolution● Concurrent (lock-free in most Vms)

● Pure modular classloading● Can only resolve what they import

● External configuration (module.xml)● Dynamic (can be redefined)● Extensible (JBoss OSGi)

module.xml

JBoss Modular Service Container (MSC)

● Small, lightweight and efficient● Highly concurrent scalable state machine

Dynamic Model Representation (DMR)

● Central detyped management API● All management operations with/on DMR● Backwards compatible

● Can be used to control standalone or domain● Detypes (i.e. string based) API uses small set

of Java classes● Various transports (Java remoting,

JSON/HTTP)

Dynamic Model Representation (DMR)

Managing with cli

● Text base user interface● Easy to use both for standalone and

domain mode● Scriptable.● Demo....

Managing with webconsole

● A demo is better than tons of words...
