What is a cloud-ready architecture

● High degree of Automation

● Flexible Management

● Frugal Use of Resources

● Open Platform

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]

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

Frugal Use of Resources

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

Performance – Boot-time / Footprint

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 6 Distributed Domain Architecture

● Domain can span environments.

● Secure management connections with SSL or TLS

● JON can also manage and monitor hosts on EC2
