    The Virtualization Practice analyst Bernd Harzog said the Software Defined Data Center is an important, significant, beneficial and disruptive change that will need to be managed differently than the way IT has managed it in the past.

    Specifically, what’s causing this change? The demand for business functionality in software is insatiable. The environment is changing. “We’re going from fewer, higher powered servers to more scaled out servers. We’re virtualizing things and putting things in pools.”

    Harzog warned the audience that managing an SDDC isn’t something IT can address by having the people who manage a legacy environment do a couple of point releases to their management products. He targeted the Big 4.

    “You can’t take something that was built for static, dedicated, and infrequently changing environments and do a couple of point releases to it and use it to manage rapidly changing, highly dynamic, highly shared and distributed environments.”

    To keep from getting burned, IT should approach their software purchases using the Angry Bird model, suggested Harzog. Try it for free. Use it in a production environment. “Do not buy another piece of management software unless you have seen it work with your own eyes in your own environment.”

    Another tidbit Bernd shared was that Operations Management is the core of running an SDDC. “Trying to run a virtualized data center without an operations management solution to manage the effect of resource utilization upon performance is crazy. You shouldn’t do that.”

    He added that if the software can’t keep up with the changing environment all by itself, then that’s a problem. It seemed he wanted the audience to really think about how they measure and report performance.

    We understand that response time is important. He explained three ways to look at response time are to review the meanings of deterministic, real time and comprehensive. “Deterministic means you have to get the actual number and not an estimate of the number. You can get into a lot of trouble when getting an average of 15 numbers.” He defined real-time as getting data within a second or two. And comprehensive means don’t miss the peaks.

    He shared an image that broke down vendors in each category from his SDDC stack and mentioned several players. If you’re reading this post and are still at VMworld, take some time to visit some of the companies on the list - especially booth 429 (wink, wink). You can also visit for more thoughts from Bernd Harzog on SDDC, applications performance management, capacity management, and other topics regarding performance and service delivery.
