3. 3
What is a cloud-ready architecture
● High degree of Automation
● Flexible Management
● Frugal Use of Resources
● Open Platform
PHYSICAL VIRTUAL PRIVATE PUBLIC
JBOSS ENTERPRISE MIDDLEWARE

4. 4
Automation

5. 5
JBoss EAP 6 Standalone Architecture
● Preserved simplicity
from earlier JBoss
EAP versions
● Server Instance is the
Unit of Automation
● Enhanced by EAP 6
Management APIs

6. 6
JBoss EAP 6 Distributed Domain Architecture
● Domain
● DomainController
● HostManager
● ServerGroup
● Cluster

7. 7
Flexible Management

8. 8
Management Options
● JBoss EAP Command Line Interface (CLI)
● Graphical Console
● Native Java Interface
● JBoss Operations Network (JON)
● HTTP/REST Interface
● Direct XML Editing

9. 9
JBoss EAP 6 Management : jboss-cli
● Transactional Interactive Client
● Connects to Standalone Instance or Domain Controller
● *nix based shell syntax, resources as files
● Contextual command and resource tab-completion
● High-level compound operations
● Persistent Changes
[standalone@localhost:9999 /] cd subsystem=datasources
[standalone@localhost:9999 subsystem=datasources] cd data-source=ExampleDS
[standalone@localhost:9999 data-source=ExampleDS] :flush-
flush-all-connection-in-pool flush-idle-connection-in-pool
[standalone@localhost:9999 data-source=ExampleDS] :flush-all-connection-in-pool
{"outcome" => "success"}
[standalone@localhost:9999 data-source=ExampleDS]

10. 10
JBoss EAP 6 Web Console
● Simple
● Fast
● Lightweight
● Avoids XML Editing
● Single Instance and
Domains
● Mostly Configuration
● Basic monitoring
● Not a JBoss ON
replacement

11. 11
JBoss EAP 6 Native API
● Native API Sample
ModelNode op = new ModelNode();
op.get("operation").set("read­resource­description");
ModelNode address = op.get("address");
address.add("subsystem", "web");
address.add("connector", "http");
op.get("recursive").set(true);
op.get("operations").set(true);
● CLI Equivalent
[localhost:9999 /] /subsystem=web/connector=http:read­resource­
description(recursive=true,operations=true)

12. 12
JBoss Operations Network – Advanced
Manageability
● Central Management and
Monitoring
● Multiple Products / Versions
● Configuration Management
● Responsive Provisioning /
Deployment
● Performance and Availability
Management
● Custom Dashboards

13. 13
Frugal Use of Resources

14. 14
EAP6 Core Architecture

15. 15
Traditional Application Server Classloading

16. 16
Module Class Loading
<module name=”com.bananodyne”>
<main-class
name=”com.bananodyne.Main”/>
<resources>
<resource-root path=”mymain.jar”/>
</resources>
<dependencies>
<module name=”org.slf4j”/>
<module name=”javax.api”/>
<module name=”org.junit”/>
</dependencies>
</module>
<module name=”com.bananodyne”>
<main-class
name=”com.bananodyne.Main”/>
<resources>
<resource-root path=”mymain.jar”/>
</resources>
<dependencies>
<module name=”org.slf4j”/>
<module name=”javax.api”/>
<module name=”org.junit”/>
</dependencies>
</module>
Peer-to-peer delegation
Cyclical Graph
Similar to IDE “projects” or “modules”
JDK split into modules
NOT TRANSITIVE

17. 17
Performance – Boot-time / Footprint
Cold Boot Time
Cold Boot Memory

18. 18
Open Platform

19. 19
Open Platform
● Open Standards are essential for the success of the
Open Hybrid Cloud.
● Open Standards form the links between the
Datacenter, Private Cloud, and Public Cloud.
● Open Standards are the DNA of Red Hat and JBoss.
● Adopt Open Standards whenever possible.
● Create new technology and drive to standards when
possible.
● SEAM -> CDI
● Hibernate -> JPA

JBoss : EAP 6 Distributed Domain Architecture
● Domain can
span
environments.
● Secure
management
connections
with SSL or TLS
● JON can also
manage and
monitor hosts
on EC2
