The Virtualization Practice

When it comes to the secure hybrid cloud, Identity has many different definitions from a device a user is using to the combination device, location, password, and other multi-factor authentication means. Even with all the technology there is still the question of where the identity store lives (the bits that contain the identity for all users, devices, etc.) as well as how do you prove identity once the user goes somewhere within the cloud which is outside your control?

Securing the Hybrid Cloud

The secure hybrid cloud encompasses a complex environment with a complex set of security requirements spanning the data center (or data closet), end user computing devices, and various cloud services. The entry point to the entire hybrid cloud is some form of End User Computing device whether that is a smart phone, tablet, laptop, or even a desktop computer. Once you enter the hybrid cloud, you may be taken to a cloud service or to your data center. The goal is to understand how the data flows through out this environment in order to properly secure it and therefore secure the hybrid cloud, but since it is a complex environment, we need a simpler way to view this environment.

Agile Cloud Development

There is a new set of tools available for Caching up and down the stack which we covered within Caching through out the Stack, however in reality where is the best place to cache data for your application and what are the ramifications of using such a cache. Recently, we had a caching problem, actually two of them. Both caused by the same thing, a lack of full understanding about what was being cached. For any application, the best way to cache is to cache in memory as close to the application stack as possible, which in our stack could be within the application, the OS, or even a hypervisor based disk cache. However, which does your application actually use?


My thoughts on the VMware vCloud Hybrid Service: There was an announcement made last week about the new VMware vCloud Hybrid Service which will bring VMware Public Cloud Service to the masses later this year. There are a couple of posts from our own Virtualization Practice analysts which can be found here and here. Since there has been plenty of conversation about just what the vCloud Hybrid Service is, I am going to use this post to share my thoughts on the service itself.


On Tuesday VMware announced their answer to the public cloud: the vCloud Hybrid Service (vCHS). One of the biggest hurdles for the roughly 500,000 VMware customers has been that their on-premise, private infrastructure isn’t directly interoperable with any sizable public clouds, like Amazon AWS or RackSpace. If you want to move towards a public or hybrid cloud model you need to add additional software, like Enstratius’ offerings or VMware’s own vCloud Automation Center.


Host deployments in a Software Defined Data Center (SDDC): How do you deploy the hypervisors in your company? There are several different choices from installing from a CD, network install and/or PXE, to name a few methods currently available. When there are not a lot of physical hypervisors to worry about the CD installation works just fine and the need for automated installation gets stronger in direct correlation to the number of hosts.

OpenStack Logo

The future of OpenStack looks bright, and with the all the software-defined data center (SDDC) features contained in the recent release of “Grizzly” they are now ready to compete toe-to-toe with heavyweights like VMware, Nutanix, Dell, and HP. Whether they can start unseating VMware products in the enterprise remains to be seen, though. Despite the immediate SDDC advantage of OpenStack, companies and technologies like that of Nicira and Virsto, both acquired by VMware, are not to be ignored.
