Cloud computing is starting to come of age. It has fundamentally altered the IT landscape, dramatically boosting IT agility while lowering costs. What started out as a side project for companies like VMware has led to the proliferation of cloud providers and stacks from IaaS providers based on OpenStack, PaaS providers like Cloud Foundry, and SaaS providers like Dropbox and Salesforce.
With the news that EMC has bought Virtustream (to be completed near the end of the year), the cloud landscape does not change very much in the short term; however, in the long term, the EMC family has its work cut out for it to integrate all its cloud solutions. The EMC family currently has three, if not more, cloud options available to its customers from VMware, EMC, and now Virtustream, and the last is handled quite differently. This will cause some issues if people want to move between the various clouds. Those issues including billing, management, and technology.
Transforming IT, a subject of many discussions within organizations today, was a major topic at EMC World 2015. Lynn LeBlanc of HotLink and Edward Haletky spend some time discussing transforming IT into a hybrid cloud landscape on this Virtual Thoughts video podcast. We look not only at HotLink technology, but also at what it really takes to transform your existing environment into a hybrid cloud environment.
Mike Schumacher, who founded Lakeside Software back in 1997, has a lively and informative conversation with us in episode 17 of the Virtualization EUC Podcast. Mike’s goal when he started was simple: figure out how a Citrix terminal server would scale before the users logged into it. Anything would be better than the “screaming users” test.
We have all drunk the Kool-Aid. Software-defined networking (SDN), network functions virtualization (NFV), or both will save the world. They decouple us from the shackles of legacy networks to allow a utopia of business-driven requirements to freely flow, delivering value and freeing the network, application, storage, and infrastructure teams to have weekends off and time with their families.
There is a growing movement to abstract hardware completely away, as we have discussed previously. Docker with SocketPlane and other application virtualization technologies are abstracting hardware away from the developer. Or are they? The hardware is not an issue, that is, until it becomes one. Virtualization may require specific versions of hardware, but these are commonplace components. Advanced security requires other bits of hardware, and those are uncommon; many servers do not ship with some of this necessary hardware. Older hardware may not deliver the chipset features needed to do security well. This doesn’t mean it can’t be done, but the overhead is greater. Hardware is dead to some, but not to others. This dichotomy drives decisions when buying systems for clouds or other virtual environments of any size. The hardware does not matter, until it does!
