Cloud management for the software-defined data center
Keith Townsend of Virtualized Geek recaps a video from Cisco on the software-defined data center (SDDC), making...
the case that while software-defined computing is mature, software-defined networking, or SDN, and software-defined storage (SDS) need some work in terms of standards and operational models. As far as realistic technology goes today, the SDDC runs along the lines of being a unicorn. That complicates the matter of picking a cloud management system. Today, the capability for multiple storage vendors must be hardwired into the platform, but once we reach the unicorn of cloud management, no major configuration changes will be needed: All will happen at the virtual SDS layer.

The basics of Overlay Transport Virtualization
Cisco's solution to migrating virtual servers across physically separate data centers is the Overlay Transport Virtualization (OTV). As Packet Pusher Ken Matlock explains, the Cisco proprietary protocol suite allows the extension of Layer 2 between data centers through the use of Layer 3 packets. Matlock offers a detailed explanation of how the suite works, running through all the essential definitions and acronyms with a step-by-step example of how OTV lets traffic flow between two boxes with no previous knowledge of each other.
Insight into the big data economy
Big data is changing the human experience, ESG's Evan Quinn says. The analyst writes that big data's role in business and personal decision-making is growing only more powerful with mounting enterprise momentum. The hype on the subject will fade as amassing huge amounts of data becomes the norm, Quinn argues, and he estimates that annual spending on business intelligence and analytics will increase 10% each year for the next several years. His latest report on the BI-analytics market landscape indicates that this growth, while rapid, is impeded in part by the ballooning number of market entries. The vendors that will survive will be those focused on highlighting their differentiators and building a more self-sufficient customer base.

VMware's hybrid cloud: Integration to disrupt the industry
Amazon's public cloud has seen some major momentum, Greg Ness acknowledges on his Archimedius blog, but it's VMware's hybrid platform that will more powerfully drive cloud's evolution. He points to VMware technologist Joe Baguley's perspective: "You should be looking at using public cloud as a natural extension of your own data center." While many of the so-called hybrid clouds touted by vendors today are merely two separate clouds jointly managed, VMware emphasizes integration of the public cloud with the automated data center. Implementing seamless integration for a hybrid cloud that's truly one entity rather than two will spell the real evolution in the industry, Ness argues.
