With our first release, we already understand Forrester’s analysis on the challenges and evolution of a well-established Software Defined Data Center (SDDC). The space is not over yet…We have something exciting coming up - the underlying opportunities of a Software Defined Data Center! According to Forrester, the opportunities of SDDC are a radical paradigm shift that transforms the traditionally infrastructure-centric data center into an application or business service focused environment. In what way? Let’s explore this by understanding Forrester’s evaluation on SDDC opportunities through its architectural and resource overviews:
SDDC Architectural View:
Forrester believes that the architectural overview of SDDC provides a building plan for a data center at a high level of abstraction. Moreover, the overall architecture of the SDDC will include several layers of functionality on top of existing virtualization capabilities that include four main components:
Virtual resource pools and physical resource pools: Forrester believes that the foundational capability of SDDC is to create and manage the pools of virtual and physical resources.
Service design: SDDC’s ultimate aim to enable the rapid deployment of services to answer business necessities. The services design layer will be a primary interface to the SDDC that will specify the workloads and the services that run on the SDDC.
- Deployment and runtime: The success of the entire SDDC concept depends on maximum flexibility in allocating resources from predefined pools and in incorporating changes so the deployment and supporting runtime will be required to fulfill actual resource binding until the last possible moment.
- Enterprise management gateway: The SDDC will have to present and consume information to and from existing legacy enterprise management stacks. Absence of this competency will deteriorate adoption, as legacy enterprise management stacks will need to incorporate data from the SDDC, and legacy monitoring tools must be able to at least view individual components of the SDDC.
SDDC Resource Overview:
According to Forrester, SDDC services are composed of Physical and Virtual Resources. The services, which are the workloads deployed in the Software Defined Data Centers, are stored in a catalog and can be deployed either programmatically or via a role-based portal. These services are composed of one or more of the following resources: Server resources, Storage resources and Network resources.
Furthermore, Forrester identifies SDDC opportunities by comparing it to other trends - Converged Infrastructure and Workload-centric IT Infrastructure. Forrester believes the SDDC concept is complementary to these two major trends in the land of enterprise infrastructure.
For workload-centric architectures, SDDC concepts will have a major effect on future infrastructure architecture and execution. Also, SDDC is a way of identifying the infrastructure for a given workload and can be used as the predominant tool to define a workload-centric architecture across a portion of the SDDC resource sphere.
With Converged Infrastructure (CI), Forrester expects that SDDC products should be able to easily integrate present and future CI product offerings as a resource and as these CI products all include facilities for virtualizing critical user interfaces, they should be easy to incorporate into the SDDC framework.
As we can see, a pretty nice list of capabilities about SDDC coming up from the all-embracing Forrester report. Again, stay tuned and be sure to check out few more!
