The Cloud Management layer of the Software Defined Data Center is where the flexibility of the SDDC is translated into tangible benefits for the business constituents of the virtualized data center, the private clouds, the hybrid clouds and the public clouds. Without a robust Cloud Management layer, the IT Operations flexibility of the SDDC cannot translate into the relevant level of Business Agility for the business.
By far, the lowest hanging fruit of virtualization and cloud environment security is the segregation of your management control from your workloads. Separation of data and control planes have been recommended for everything from storage (EMC ViPR) up to the workloads running within virtual machines. The same holds true for cloud and virtual environment management tools, tasks, and functions. Up to now there have been very few choices in how such segregation could occur using properly placed firewalls or by using some form of proxy and the only proxy available was HyTrust. But this has changed. There are some other tools that will help with this segregation of data from control and do they give the level of auditing we require to solve the delegate user problem?
Tintri is now shipping version 2.0 of their array software, Tintri OS, which further automates administration of their arrays and adds ReplicateVM remote replication features. ReplicateVM is an incredibly flexible asynchronous, IP-based replication technology that operates per-VM, allowing each VM to have custom RPOs.
At EMCworld 2013, one of the big stories was Pivotal and it’s importance to the EMC2 family and the future of computing. Pivotal is geared to provide the next generation of computing. According to EMC2 have gone past the Client-Server style to a scale-out, scale-up, big data, fast data Internet of Things form of computing. The real question however, is how can we move traditional business critical applications to this new model, or should we? Is there migration path one can take?

What is the future of virtual storage in a Software Defined Data Center (SDDC)? As more and more technology gets moved from hardware to software in the SDDC, I have to wonder which direction virtual storage will go.
If we use networking as an example, the technology has evolved from setting up local virtual switches on each of the hosts to a virtual distributed switch (VDS) model where all the individual host-level virtual switches are abstracted into a single large VDS that spans multiple hosts at the Datacenter level. In this design, the data plane remains local to each VDS, but the management plane is centralized with VMware vCenter Server acting as the control point for all configured VDS instances.
If BMC is taken private, the same fate will likely befall other legacy enterprise management software vendors like CA, and the management software divisions of IBM and HP. This will start the process of the replacement of these products by new ones built from the ground up for virtualization and cloud computing, and mark the start of the disruption of the entire management software business.
