The Software Defined Data Center: That was pretty much the biggest takeaway from this year’s VMworld in San Francisco. VMware made announcements about the new vSAN that will be coming out soon to enhance software defined storage and about the NSX platform that addresses one of the final hurdles on the path to finally having a completely software defined datacenter, network virtualization. There have been plenty of write-ups on these topics, including one very good post from one of my colleges, Bernd Harzog. I am not going to go into any details on those announcements except to say that VMware is expanding and putting themselves in a good position to be the center of the virtual universe. I believe that it will take some time for software defined networking to really take off. My gut is telling me that it will be a slower process at first, just like the adoption of server virtualization, but when it does really take off, I believe the end result will have the potential to have just as great or even a greater legacy than server virtualization has.

At the US VMworld 2013 conference, VMware did an excellent job of explaining how network virtualization and storage virtualization were going to work. Adding network virtualization and storage virtualization to the existing virtualization of compute (CPU and memory) along with API’s and policies to manage the whole thing is what creates a software defined data center. Continue reading VMworld 2013 Wrap Up – The Software Defined Data Center
At VMworld 2013 and on the Virtualization Security Podcast there were many conversations about VMware NSX. These conversations ranged from how will we implement this new technology to security, scale, and other technical questions. In addition, NSX and what was needed to make it a reality may be the answer to a nagging security question. Brad Hedlund, from the VMware NSX team, joined the Virtualization Security Podcast to share with us some of the details around VMware NSX prior to the podcast.

I spent two days at PuppetConf 2013 in San Francisco this week, and the common themes were automate everything, monitor everything, provide feedback early in the process, and focus on culture. All four of those topics aligned with the DevOps movement, with the goal of faster and more reliable deliveries. Companies that can deliver software more frequently with fewer issues have a competitive advantage over those who can’t. Continue reading How DevOps Can Help Automate the Pain Away
By Greg Schulz, Server and StorageIO @storageio
Keeping in mind that the best server and storage IO is the one that you do not have to do, then second best is that which has the least impact combined with best benefit to an application. This is where SSD, including DRAM- and NAND-flash-based solutions, comes into the conversation for storage performance optimization.
The question is not if, but rather when, where, what, and how much SSD (NAND flash or DRAM) you will have in your environment, either to replace or to complement HDDs. Continue reading When and Where to Use NAND Flash SSD for Virtual Servers
I was fortunate enough to have the opportunity to attend PuppetConf 2013. When I walked into the first keynote session, I was shocked by the size of the audience. Over 1300 people were packed into the ballroom. Another 3700 had signed up to watch the event streaming online. Last year there were 800 people at the conference and only 300 the year before. Obviously, both Puppet and DevOps are hot topics these days. Continue reading Recap of PuppetConf 2013 in San Francisco
