“If we had to pick a winner, it would be JBoss. The only
application server in the group whose score never dropped below a
4, and interestingly the received the joint fewest top marks of 5 in the
categories. JBoss consistently performs very well in each category
which is why it also shines in the developer profiles exercise. Yes it is
a bigger download and larger in memory consumption than most, but
performance wise for a developer, it doesn’t show.”

13. New WebServer - Undertow
• Blocking / non-blocking NIO based APIs
• Composition/handler based architecture
• Lightweight & fully embeddable
• Supports Servlet 3.1 & HTTP upgrade
#DV13-WF
@dandreadis

14. Port Reduction
• HTTP Upgrade allow us to reduce the number of ports in
the default installation to just 2:
•
•
8080 – for applications with JNDI and EJB multiplexed
9990 – for management, for both HTTP/JON & Native APIs
• The only overhead is the initial HTTP Upgrade
request/response.
#DV13-WF
@dandreadis

15. Simple non-blocking handler
Undertow server = Undertow.builder()
.addListener(8080, "localhost")
.setHandler(new HttpHandler() {
@Override
public void handleRequest(final HttpServerExchange exchange) throws Exception {
exchange.getResponseHeaders().put(Headers.CONTENT_TYPE,"text/plain");
exchange.getResponseSender().send("Hello World");
}
}).build();
server.start();

16. Undertow as Reverse Proxy
• High performance reverse proxy
• Handles both AJP and HTTP backends
• Supports round robin load balancing
• Support for mod_cluster is planned
• Still under heavy development
#DV13-WF
@dandreadis

17. Single Instance Patching
• WildFly/EAP is used on its own or as the base for other
•
•
•
•
#DV13-WF
projects/products (e.g. SwitchYard/SOA-P)
Patching allows updating of libraries and configuration
files in an installation (a.k.a. identity)
Patches come in the form of .zip bundles containing
updates and metadata.
Multiple one-off patches can be applied but are
invalidated by the next point/CP release.
Rollbacks are possible.
