Java Virtualization for Server Consolidation

Posted by ryuzaki0 on from the cuppa-server-joe dept.

Steve Wilson writes "Cassatt Corporation has released new software that enables administrators with large J2EE farms to much more efficiently use their resources. In order to do this, it leverages the virtualization capabilities inherent in the JVM to create a single shared pool of hardware resources which which all J2EE applications can draw."

    Cassatt's control software costs about $100,000 for a 40-server pool. Adding the Web Automation Module increases the cost by about $5,000 per server, the company said.
    Ok, so I can run java apps that save me lots of money on server hardware... for $100,000. unless I want to spend an extra $5,000 per server (bringing the total up to $300,000). So how is this going to save me money? I mean, I could by a whole bunch of 1U Dell P4 servers each valued at about $2k a piece. 40 of those would be only 80 grand. Now, I'm pretty sure that I pay my adminstrators so they can make an informed decision on grouping two or three services on a machine where it makes sense (like dns resolution and dhcp serving) and instantly save me a few machines there. And how many of my mission critical resource poor services are executed in Java? This seems like a huge waste of money to me. Besides how hard could this have been to come up with.. I mean, Java is running IN A VM in the first place. run an identical VM on another machine, add a little code to allow transfering of processes between VMs and you've got it. I'm sure it's got some tricky aspects, but is it that hard that it'll cost $300,000 to do? Something's fishy here...

    The Cassatt Collage software currently runs on Linux, Solaris and Windows. Intel, AMD and SPARC processors are all currently supported. You can manage all these kinds of servers within a single-shared environment.

    Just an FYI for those of you who just joined us. Steve Wilson was the co-author of Java Platform Performance, along with Jeff Kesselman (the Java gaming dude, who still works at Sun). So he's pretty well versed in how Java technology works.

    Now on to my own question. :-)

    Steve, the one thing I'm not getting from the article, nor from the website (at least, I haven't seen it yet) is as follows: Is this just another DRMAA implementation, or is it more than that? If it is, could you give us a good overview of why it's better than N1? If not, can you explain what exactly this software does for a company? It somewhat sounds like it makes a single JVM run across multiple machines as if they were one, but if that's the case, how does it work? Is it a customized JVM based on Sun source code?

    Thanks in advance!
