CloudComputing

Off of the hypervisor and get into the cloud: In my last couple of post I wanted to express my thoughts about the future of cloud computing. In the first post, I shared what appears to be a bright outlook of the future for people working in the cloud space with the soaring demand for skilled engineers and not enough quality people to fill those roles. In my second post, I presented a couple of key skill areas that currently seem to have the most demand but I want to share my thoughts, or more to the point, concern that this “gap” of skilled engineers in only going to increase unless we can help guide people off of the hypervisor and into the cloud.

DataCenterVirtualization

Many network virtualization products appear to be aimed at the top 10,000 customers worldwide, accounting for their price as well as their published product direction. While this is a limited and myopic view, many claim it is for the best, their reason being that network virtualization is only really needed by the very large networks. The more I think about this approach, the more I believe it is incorrect. Let us be frank here. Most networking today, within many different organizational sizes, is a hodgepodge of technologies designed to solve the same problem(s) over and over: how to get data quickly from point A to point B with minimum disruption to service.

In early 2012 SanDisk, well-known manufacturer of flash memory products, acquired FlashSoft. Like a number of other companies in the virtualization storage space, FlashSoft has several different products designed to use SSD and flash memory to cache storage I/O. They have specific products for Microsoft Windows Server and Red Hat Enterprise Linux (and clones). They also have a product for VMware environments, SanDisk FlashSoft 3.1 for VMware vSphere.

Working with LDAP and Microsoft Active Directory: For most IT professionals, there has been some point in their career where they have connected a product or service to a Microsoft Active Directory with LDAP for authentication. This is really nothing new and has been done for years, but I discovered a different way to set up the connections years ago when I was working on a script that would connect to Active Directory with an LDAP call to get a list of members of a group. I really thought most people already knew this and it was pretty much common knowledge, but it seems lately that every time I work with someone new setting up the LDAP configuration they seem to be quite surprised at the way I do things and I thought this should be something that I share out.

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.
