Cloud Computing: Software Defined Storage Needs a More Clearly Defined Value Proposition
April 6, 2015
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…
These include application agility, management automation, and the utility usage model. As compared to the previous networking paradigm, SDN’s centralized control (or “control plane”) coupled with simpler architecture and management requirements, make SDN a cloud enabler—hence SDN’s ability to penetrate both hyperscale and traditional enterprise IT environments in volume…
