3. AS7 in a nutshell
Fast
●
Very fast
●
Blazingly fast (<3s startup)
●
#@*%ing fast
●

4. AS7 in a nutshell (seriosly)
●Blazingly fast (<3s startup)
●Lightweight
●Modular core
●Hot, parallel deployment
●Elegant administration
●Domain management
●Easy testable

5. Boot time

6. Memory

7. 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

8. Simplified user-focused configuration

9. 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

10. 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

11. 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

12. Domain mode

13. Demos
●
Booting standalone mode
●
Booting domain mode

14. Architecture

15. 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

16. Hierarchical classloading

17. Modular classloading

18. 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)

19. module.xml

20. JBoss Modular Service Container (MSC)
●
Small, lightweight and efficient
●
Highly concurrent scalable state machine

21. 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)

22. Dynamic Model Representation (DMR)

23. Managing with cli
●
Text base user interface
●
Easy to use both for standalone and
domain mode
●
Scriptable.
●
Demo....

24. Managing with webconsole
●
A demo is better than tons of words...
