Battle for the Cloud: Google vs. Microsoft
Battle for the Cloud: Google vs. MicrosoftDomain-Driven Design in an Evolving Architecture
Domain driven design can be most readily applied to stable domains in which the key activity is for developers to capture and model what is in users' heads. But it becomes more challenging when the domain itself is in a state of flux and development.New Mule Performance Benchmark: Yup, we come out on top.
WSO2 has felt the need over the past few months to make many false claims about Mule’s performance. I ran their benchmarks. Sure enough, with their configuration, Mule performance was crappy. There were a couple fatal flaws with their benchmark though.Beyond REST? Building Data Services with XMPP PubSub

For the last 2-3 years, Brian Aker and I have had many discussions about how to refactor MySQL. Brian has been the one driving these discussions by asking why some things in MySQL were done in a certain way and in a true "what if" manner asked what would happen if we would do things in another way.JBoss Cache 3.0.0 Alpha Available
The first alpha of JBoss Cache 3.0.0 - codenamed Naga - is out and available for download. In a nutshell, it is a truly open source (LGPL) distributed enterprise cache, which is often used as a library to remove data retrieval and calculation bottlenecks, or as a mechanism to share state across a cluster either for failover or load balancing, creating data grids, etc. I have also seen it used as a distributed in-memory object database of sorts, as a fast alternative to a more traditional database when typical DB features and guarantees aren't criticalSubversion up and running in 30 minutes or less
Subversion sounds pretty cool. It's a mature, powerful revision-control system that acts a lot like CVS, adds support for atomic commits and real renames, just won the Jolt award, and is free. What more can you ask for?From OSGi to GlassFish in 5 Steps

Reading about another story of Rails performance, I grabbed JMeter to benchmark one of my current projects. Not so much as a comparison for Ruby - which managed 320 requests per second - but more as a comparison of Jetty and Glassfish.WSO2 adds data services and security features in Mashup Server 1.5

A collection of blog posts from Archimedius about the smack down between VMware and Microsoft as analysts prepare for VMware's upcoming earnings announcement Tuesday July 22.SQL Injection Part II (Make Sure You Are Sitting Down)
Back in February I wrote a blog post on SQL Injection that included an example of how a malicious user might inject into a character field even though ColdFusion escapes single quote marks. The attack involved other forms of escaping single quotes - and was effective against MySQL. This week I stumbled upon (more like a train wreck) an attack that is much more sophisticated - and also involves injection into a character field. I am told.....Perspectives - Flickr DB Architecture
I’ve been collecting scaling stories for some time now and last week I came across the following run down on Fliker scaling: Federation at Flickr: Doing Billions of Queries Per Day by Dathan Vance Pattishall, the Flickr database guy.My testimonial about Hudson
I have tried some tools for Continuous Integration before, like Cruise Control and Continuum. At the time I have tested them, some years ago, the first one was not very simple to configure and the last one used to be visually more interesting, but the project was just starting, so it had some problematic bugs. Because of that and because of the project build that I was working was simple without dependencies (it was just checkout the code from SVN, compile, run the tests, publish the results, deploy the application and notify about breaks sending and email and a SMS), it was decided schedule the Ant scripts directly as cron jobs. It actually worked very nice in that context.Open Source IDE for Apache Synapse
Apache Synapse is an Open source Enterprise Service Bus, and the WSO2 ESB provides an IDE and some more management to it....State Observation: The Good (JXI), Bad (JMX), Ugly (JMX)
One of the most common usages of JMX is to make instances of a particular object and its associated state visible from a remote machine for diagnostics purposes. But how easy is it really?Apache Geronimo on Grails
Do you want to build your Web sites faster and cheaper, but still leverage industrial-strength technology? You can do just that using Grails and Apache Geronimo. Grails leverages the power of the dynamic language Groovy to accelerate your development. However, it runs on the Java® Virtual Machine and leverages proven Java technologies. This makes it easy to take your Grails application to the next level by deploying it to Apache Geronimo, the premiere open source Java EE V5-certified application server. In this article, you will see how easy Grails can make Web development and how easy Geronimo can make Grails deployment. You will also see how a Grails application can leverage the resources and services provided by Geronimo.Why Should I Care What Server My Application is Running On?
Imagine this – you develop an application on your machine and then, when you come to deploy it to the production server, all of a sudden, you encounter various errors and failures. Or maybe, when you decide to switch your hosting provider, your application stops behaving the way it should. How about this – one day, out of the blue (well, out of your IT manager’s whim) your application just misbehaves. Sounds familiar?Database Scalability

It's been several months since my last blog. The reason is that I have been deeply involved in this new product called MEP (Mobile Enterprise Platform) and I really couldn't say much about it. However, version 1.0 has just been released, so it's time to open the blog gates. See announcement here for additional info about MEP.
