The OpenStack Summit this week continued to fan the flames of the software-defined data center. The software-defined data center is just a term for replacing traditional data center hardware functionality with the same features implemented in software, running on commodity x86 servers. While software-defined approaches to data center features are at least nominally less expensive than their hardware counterparts the real promise in the approach is flexibility and management ease with high levels of integration. Reconfiguring a network to support the security requirements of a new application is now just a function of software and APIs. Expanding storage is just simply adding another node with more storage attached, and the cluster compensates automatically. Even things like firewall rules and load balancer configurations can now be stored as templates along with the applications, to be provisioned in minutes.

VMware has added some significant meat to the bones of its Software Defined Data Center Strategy with the announcement of the VMware NSX Network Virtualization Platform. NSX represents the combination of the previous VMware network virtualization technology (VXLAN) with the technology that came from the acquisition of Nicira. Continue reading VMware Fleshes Out SDN Strategy with NSX
Is it possible to use a cloud framework to better secure your datacenter? Do cloud technologies provide a secure framework for building more than just clouds? We all know that virtualization is a building block to the cloud, but there may be a way to use cloud frameworks to first secure your datacenter before you launch a private, public, or hybrid cloud. In essence, we can use tools like vCloud Director to provide a more secure environment that properly segregates trust zones from one another while allowing specific accesses.
Brocade has stated they will buy Vyatta for an all-cash deal. This is good news for Vyatta and perhaps a way for Brocade to partake of software that could rival VMware’s purchase of Nicira when Vyatta’s own SDN features are married with Brocade Ether Fabric technology. Brocade has been in the software business for a while now, but only with respect to their own hardware. With the acquisition of Vyatta, they will shortly own a building block that can extend Ether Fabric into the virtual and cloud environments. It would be shortsighted to say this is just an SDN play—this purchase shows there is quite a bit of benefit to Brocade. Continue reading Vyatta: Building Block for Brocade SDN Plans
While not particularly new news, the next version of the Cisco Nexus 1000v will be free, unless you want the security features. This is an interesting shift from Cisco with respect to VMware vCloud Director, the Nicira purchase, furthering UCS, and Cisco within non-UCS data centers. However, given other announcements, with respect to OpenStack, perhaps this is more a play to level the playing field between cloud architectures? But what I find most interesting, is that the changes to the Nexus 1000v also align with the changes we see in the vCloud Suites from VMware. Continue reading Cisco Nexus 1000v: Free unless you want Security
When enterprises consider putting business-critical workloads in public clouds, many of them overlook, at least in part, critical issues of economics and over what portion of their cloud software stack the cloud vendor has full control. This leads to a situation where sometimes relatively inexpensive offerings where the vendor has full control of their software stack (like Amazon EC2) are improperly compared to an offering from a vendor like Savvis or Terramark who is building a cloud out of either VMware-provided components or OpenStack components. This gives rise to important issues that drive both the cost of the respective offerings and the degree to which the cloud vendor can both enhance the offerings with rapid agility and quickly address service level issues.
