Cloud Computing: Software Defined Storage Needs a More Clearly Defined Value Proposition
Grazed from Forbes. Author: John Webster.
The Software Defined Storage (SDS) model in its early days was often compared to Software Defined Networking (SDN). Both used virtualization as a foundational technology and replaced hardware constructs with software loaded onto general purpose, open, commodity platforms. The early vendors of SDS such as EMC also applied SDN’s data plane/control plane abstraction model to SDS although that reference has died down considerably. Since then, SDS has gone its own separate way.
However, the comparison remains worth exploring even now. SDN has become a fundamental cloud construct—as fundamental as server virtualization—and as such has achieved far more success to date than SDS. The question is why? SDN vendors point to how they have been able to greatly simplify the management of large networks making the attributes of cloud computing possible…


Piston Cloud Computing, Inc. today announced the availability of Piston CloudOS 4.0, an operating system for the modern data center that transforms clusters of commodity servers into a single unified environment. Used to deploy OpenStack in minutes, CloudOS 4.0 now allows customers and partners to also deploy Hadoop and Spark on bare metal, with forthcoming support for container orchestration tools such as Kubernetes, Mesos and Docker Swarm.
