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
Automation
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
JBoss EAP 6 Distributed Domain Architecture
● Domain
● DomainController
● HostManager
● ServerGroup
● Cluster
7
Flexible Management
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
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
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
JBoss EAP 6 Native API
● Native API SampleModelNode 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:readresourcedescription(recursive=true,operations=true)
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
Frugal Use of Resources
14
EAP6 Core Architecture
15
Traditional Application Server Classloading
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
Performance – Boot-time / Footprint
Cold Boot Time
Cold Boot Memory

Open Platform
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 in Red Hat OpenShift
22
JBoss EAP in Red Hat Cloud Forms
23
JBoss EAP with Red Hat Cloud Access
24
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
