SDDC & Hybrid Cloud

Cloud computing has evolved from focusing only on how to construct, secure, manage, monitor, and utilize IaaS, PaaS, and SaaS clouds. As the paradigm matures, it is moving from a pure resource management paradigm to a data and resource management paradigm. (Read More)

SDDC is the next evolution in on-site data center technology. It has taken the knowledge gained from the server virtualization revolution and blended it with software-defined storage and networking to create a data center defined and managed by software running on invisible hardware.

Hybrid Cloud covers the technologies and operational processes, both technical and business, for deploying, consuming, and utilizing this paradigm.

Major areas of focus include barriers to adoption; progress on the part of vendors in removing those barriers; where the lines of responsibility are drawn between the cloud vendor and the customer for IaaS, PaaS, SaaS, and hybrid clouds; and management tools that are essential to deploying and managing the cloud, ensuring its security and the performance of applications.

All Your SDN Are Belong to Us

Network Virtualization

One of the frustrations of SDN has always been the fact that if you ask six different people for a definition of SDN, you’ll get ten different answers, at least. This stems in part from the usual IT buzzword symptoms. When a system is used for competitive advantage, each company wants to define its own brand of “The Thing”—to try to “own” the thing and become the de facto standard for it. There is also a deeper issue with SDN, precisely because it is networking.

Takeaways from VMworld 2016

Here are my thoughts and takeaways from VMworld 2016 at the Mandalay Bay Hotel in Las Vegas, Nevada. First, let me say that Las Vegas really knows how to cater. The conference food was an absolute joy and a succulent treat, especially compared to prior conferences in San Francisco. No box lunches this year—and that was such a huge change that the conference food gets the first shout-out.

Dell EMC: The Big Day

Yesterday, after many worries—some regulatory (Would the EU sanction the deal? Would China sanction the deal?), some legal (Were the financial instruments being used to finance the deal unlawful under the US tax code?)—the biggest IT merger ever in terms of monetary value finally occurred. This is one of those landmark occasions. Two of the biggest names in our industry, Dell and EMC2, have merged to become Dell Technologies.

VMware Shows a Way Forward

Now that VMworld is over, it is time to digest everything we learned: to pick at the messaging for the kernel of truths and directions. Many found the VMworld keynotes to be somewhat bland and the show floor to be much of the same. However, there was gold within both. We can discuss the show floor later, as I’d like to look deeper at the messaging first. The gold was hard to put together amid all the different messages. Themes included cross-cloud, Photon, NSX, and VSAN. These may seem disjointed until you look deeper. The messaging could be better, and I expect it to improve by VMworld Barcelona. Yet, there was clearly a path forward for each of VMware’s customers.

Maintaining Pool Performance

Pooling and sharing of resources is a feature of many data center technologies on which we rely. But this approach has a challenge in that the pool has a finite size. If there is not enough resource to satisfy all the resource demands, then something will suffer. We frequently see this in new virtualization deployments. A cluster is built, and VMs are deployed. Over time, more and more VMs are deployed until the cluster becomes overloaded. The same overloading can happen on the network and storage resources, leading to performance issues. To avoid performance problems, we need to manage resources to make sure we satisfy demands. Ultimately we need to make sure we deliver resources where they provide a benefit to the business.
