Java on Microsoft Azure

Triggered by my colleague Koen Van Oost and the upcoming Microsoft session at Devoxx, I looked into Java on the Microsoft Azure platform. Watched the talk "Open in the cloud: Windows Azure and Java" of PDC10. I wasn't aware that one could run Tomcat on Azure! Well, seems to be the case already since 2009. But the Eclipse tooling and JDBC connection to the SQL Azure Database are brand new. During the talk, it was also shown how the Fujitsu Interstage application server can run on Azure. Having WebLogic or WebSphere Application Server running on Azure would be very big news! For now, let's see how the ESB and integration capabilities of Azure are usable from Java.

Devoxx 2010

Next week is Devoxx! Three talks and three speakers that I can really recommend:

• Designing Java Systems to Operate at a Cloud Scale by George Reese
  

• Does dev/ops matter for me? by Michael Coté and John Willis

• Pragmatic Cloud Computing, or, Dealing with Morlocks, or, Agile Infrastructure by Michael Coté

In particular as I invited the speakers myself for these talks! Just too bad that I can't be there myself, damned.

But many more interesting things: Activiti in Action by Tom Baeyens, Scalable Java Applications on Azure by Microsoft, Comparing JVM Web Frameworks by Matt Raible, Encryption Bootcamp on the JVM, loads of NoSQL stuff, and so many more great talks.

Looking forward to meet you next week @ Devoxx on Monday, Tuesday or Wednesday.

Dell acquires Boomi

Boomi is a very interesting Integration-As-A-Service player. Integration in the cloud is a new trend that looks very promising. But what is not yet clear is the reason why Dell acquired Boomi. A big cloud player such as Google or Amazon or a big software players such as Microsoft, IBM or SAP have probably more chances. Curious to see what direction Dell will take with Boomi.

XML schema's for verticals

With XML as the alphabet, many languages are defined through XML schema's. But typical is the way each vertical defines its own language. Latest example that I was pointed at: XML schema's for the oil industry at energistics.org.

But there are very little initiatives to define a common foundation, to define the words (nouncs, verbs) from which each vertical could define variations or specific XML languages. Many XML languages lead to many translations or transformations. Fine for us the integration experts, but overall not very efficient. ebXML Core Components gave the structure to define re-usable XML building blocks that could be used in different contexts and adapted based on region, industry, business process etc. But ebXML CC is used in some of the verticals, but not one a broad scale as is the case with good old EDIFACT.

And as the XML standards in the oil industry proof, the trend of the last 10 years continues, many domain specific XML languages, specific for each vertical.

Cloud Computing Economies of Scale

Great recorded talk about the hardware and data centre side of cloud computing. This great presentation explains why it (also) makes sense to leverage cloud computing simply to have cost efficient hardware. Got pointed to it while listening to the Cloud Computing Show #31.

Also interesting (via the same podcast): CloudHarmony. The blog in particular contains different benchmark results (memory, IO, network) of a large number of Infrastructure-As-A-Service providers.

B2B market

IBM keeps acquiring other companies:

• Lombardi being a BPM solution of which some of my colleagues are quite enthusiatic.
• Sterling is more an "old" player in the B2B space with products such as Gentran for B2B communication and ConnectDirect for managed file transfer. But Sterling is also an Integration Service Provider (Garnter) or still call it a Value Added Network? IBM sold its VAN to GXS quite a while ago.
  
• Cast Iron Systems which is a new kid on the block, with a solution specificially targeting cloud integration. Also available as an appliance. And Cast Iron was rumoured to be developing a cloud based integration offering.
  

Funny to see and "old" (Sterling) and brand "new" player (Cast Iron) being acquired in the same timeframe. Of course I'm curious to see what IBM will do with these acquisitions. Will they die in a corner or be successor of the DataPower success story? And how will they explain and position all these technologies at customers?

Java: execute program without blocking

A long while ago that I had done some Java programming... How to run a program from within Java in a decent manner. While looking around for some sample code, most solutions use the Process.waitFor() method to wait for the process to terminate. But that will usually block forever as process writes data to stdout or stderr and nothing reads that output.

One option is to use a separate thread to read stdout/stderr. I opted for an even simpler approach: temporary files:

execCommand = execCommand + " > " + stdoutFile.getFileName();
execCommand = execCommand + " 2> " + stderrFile.getFileName();
// command/program > stdout-temp 2> sterr-temp
Process p = Runtime.getRuntime().exec(execCommand, null, currDir);
int exitValue = 0;
boolean isRunning = true;
int waitSeconds = 30;
while(isRunning && (waitSeconds > 0)) {
try {
exitValue = p.exitValue();
isRunning = false;
} catch(IllegalThreadStateException e) {
// process is still running, wait 1 second
try {
Thread.sleep(1000);
} catch (InterruptedException e1) {
// ignore
}
}
waitSeconds--;
}
if (isRunning) {
p.destroy();
exitValue = 9999;
}
stdoutFile.delete();
stderrFile.delete();
