Red Hat CTO elaborates on lofty ‘cloud’ vision discusses the effort Red Hat is making to engage its customer base on Wall Street: “In terms of engaging its customer base, for example, Red Hat has worked with Wall Street’s financial institutions to simplify data center operations by capturing a single operating system image, including hardware and […]

I just stumbled upon a curious headline “Sun Plans To Close Its Data Centers” describing a post by Brian Cinque. Brian’s post was about Sun’s aggressive work within SunIT to reduce data center costs, including power and cooling requirements as well as the continuing vision of utility computing as seen by SunIT. The program has […]

The typical method employed for migrating existing workloads to ESX from physical machines involves instrumentation of the workload in the current environment, coupled with technical and business analysis to determine:

Workload suitability for virtualization ESX resource requirements to support the workload

The technical resource sizing method most often used leverages the VMware Capacity Planner. VMware capacity planner employs an […]

I stumbled across more detail from Rich Manalang regarding the Oracle Mix deployment on JRuby and the Oracle Application Server. I orginally wrote a post about this after meeting Rich and Jake at Oracle World last week. Its more than a little interesting, but not surprising or atypical, that finding production hardware consumed so much […]

Success with Enterprise SOA depends on the ability to develop and drive governance models that align business objectives with IT strategy. Given that many organizations struggle with operating IT in a way achieves business capability that extends beyond pure cost containment and reactionary service fulfillment, success with SOA should be enhanced by prior success with […]

Oracle Mix may be the first production deployment of JRuby, and is certainly the first deployment of JRuby in an Oracle Application Server. I got a chance to meet and talk with Rich Manalang and Jake Kuramoto who have been working on getting the site up. It took a mere two weeks to put the […]

Vladis’s Blog has just posted an entry on good and bad reasons to virtualize titled “Virtualisation, comfortable or tight trousers“. I’d like to elaborate on the subject a bit. Vladis mentions several important drivers supported by measurable, direct IT operational cost reductions, typically enabled by:

More efficient use of the existing server footprint through higher utilization, More […]

In my recent post Virtualization and Infrastructure Modeling I neglected to mention SysML. SysML is a set of specifications for extending the UML for systems engineering disciplines, described by the OMG as “… a general-purpose graphical modeling language for specifying, analyzing, designing, and verifying complex systems that may include hardware, software, information, personnel, procedures, and […]

The OMG Model Driven Architecture (MDA) explores the formal concept of transforming and instantiating models. “In the MDA, models are first-class artifacts, integrated into the development process through the chain of transformations from Platform Independent Model (PIM) through Platform Specific Model (PSM) to coded application.” The “coded application” terminology is bit unfortunate, since the MDA concepts, […]

An intriguing aspect of ITIL change expected in a virtualization project is CMDB. I missed this on my recent post on ITIL and virtualization. It’s a funny slip, in the sense I’ve been pondering this subject quite a bit lately. Virtualization concepts are increasingly realized in all the classic components of infrastructure: compute, storage, and networking. […]
