The Virtualization Practice

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.

Nutanix OS 3.5: Deduplication, New GUI, SRM, Hyper-V Support

Nutanix, one of the fastest growing IT infrastructure startups around, shows no signs of slowing down with their release of Nutanix OS 3.5. For those not familiar with Nutanix, they offer a truly converged virtualized infrastructure. This generally consists of four nodes in two rack units of space, where each node has CPU, RAM, traditional fixed disk, SSD, and Fusion-IO flash built in. Their secret sauce is really NDFS, the Nutanix Distributed File System, built by the same folks that created Google’s File System, as well as a unified, hypervisor-agnostic management interface.

See you at the show! The time is almost here where several thousand people from around the world will make the pilgrimage this year to San Francisco for VMworld 2013. This will be my last post before the start of the show and people are packing and preparing to leave I wanted to share with you what I think is the way to get the most out of your time at the show.

The next generation of data protection is not just about backup or replication into and out of the cloud, but about inexpensive recovery directly into a cloud in a hypervisor agnostic manner. Recovery is the key to backup and while we spend many hours ensuring that our backups happen in a timely manner, we spend very little time testing those backups and ensuring that recovery can happen at any time for any workload, not just those that are mission critical. Next generation data protection must also be extremely simple to use, setup, and configure. Is your data protection tool a next generation tool or lost in the past somewhere?

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.

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.
