WildFlyWildFlyFormerly JBoss AS

Community project with goals of fraquent releasesand rapid innovation

Upstream for JBoss EAP

Fast, lightweight, manageble runtimeSupports Java EE7 and beyound

Open source, community driven projectVersion 9 coming soon!

Cloud enabled

HTTP/2HTTP/2

Reduction in page load time

GoalsGoals

No changes in network infrastructureNo changes in website content

HTTP/2HTTP/2

Binary protocol with request framing

DesignDesign

Multiplexed - many prioritized streams interleavedin one TCP connectionHeader compressionServer push - server is able to push data to a clientbefore it has asked for it

HTTP/2HTTP/2

Although not required by specification majorbrowsers require HTTP/2 to use TLS connectionswith ALPN extension

WildFly

Configuration:

configure server's security realminstall ALPN jar

Server suspendServer suspend

Server can be suspendedAfter suspend operation is executed new requestsare rejected but running requests are able to finishtheir work

Suspend operation ends when either all requestsfinish or timeout is extendedUsage example: graceful shutdown, configurationchangesServer can be resumed - request processing startsimmediately

Server suspendServer suspend

:suspend(timeout=x)

Management operationsManagement operations

:resume:shutdown(timeout=x):read-attribute(name=suspend-state)

Codebase splitCodebase split

The base architecture of WildFly has been fullyseparated, and is now versioned separately from thefull platform https://github.com/wildfly/wildfly-corewildfly full - subsystems implementing EEfunctionality https://github.com/wildfly/wildflyWe provide tooling to faciliate building WildFlyextensions and composing them into a server

Feature packFeature pack

Jar describing server extensionConsist of modules and subsystems configurationsand content filesLightweight - no jars includedCan depend on other feature packs

Build by maven plugin based on configuration fileDuring build all module dependencies are checked

Server provisioningServer provisioning

Feature packs are used by provisioning library tocreate a serverThe library can be used in standalone mode or beembedded in maven pluginMerges modules, configuration and content filesfrom all feature packsCan provision thick or thin server

Example: REST distributionExample: REST distribution

Users can use above tools to provision server withonly those parts of WildFly that are necessary intheir use caseExample: lightweight server, based on wildfly-web, with ability to deploy RESTful applications

WildFly SwarmWildFly Swarm

tool for building runnable fat-jars with embeddedWildFlycreated jars can contain only necessary parts ofWildFlybuild using maven pluginmicroservices friendly

WildFly as loadbalancerWildFly as loadbalancer

httpd based loadbalancer

mod_clustermod_cluster

Dynamic configuration of httpd workersServer-side load balance factor calculationFine grained web-app lifecycle control

WildFly as loadbalancerWildFly as loadbalancer

WildFly can now be used as front end mod_clusterbased load balancer

One tool can be used to manage front and backendserversMore efficient communication protocols, such asHTTP/2, can be used

Offline CLI supportOffline CLI support

Ability to embed a WildFly process inside the CLIprocessUsage: management of the server using CLIcommands, without having a running server

Switch to OpenJDK ORBSwitch to OpenJDK ORB

Downstream project of OpenJDKBetter interoperability with the JVM ORB and theJava EE RI
