SDDCs can help IT groups respond with greater speed to new requests for IT resources if infrastructure resources are pooled, management resources are standardized, and policy-driven provisioning is enabled. Simultaneously, a SDDC allows IT groups to maintain control on provisioning, cutting costs and navigating to application modernization.
As noted on the IBM SDDC page, “the SDDC results from years of evolution in server virtualization.” SDDCs use virtualization to create virtual machines (VMs) from hardware infrastructure and offer software and tools to manage the virtualized resources.
When a data center is virtualized, all the system’s resources can be abstracted and represented as less complex software. The server virtualization process of abstracting resources from physical servers boosts provisioning speed, increasing system utilization and reducing hardware expenditures. Server virtualization also helps enterprises realize the benefits to pooling their infrastructure resources.
Abstraction allows the resources of the data center like computing, networking and storage to be marketed as a service and gives different clients access to the data center.
SDDCs have been a boon for smaller businesses, helping them get the compute, network and storage elements that they otherwise wouldn’t be able to attain due to the cost of constructing infrastructure. The advent of the SDDC also drove more functions to the cloud, systematically altering how enterprise IT deployed and accessed applications.
As stated on the SDX Central page “SDDC offers clients who don’t have the existing infrastructure the ability to basically rent network services and resources like computing, networking and storage solutions from the cloud.” Similarly, a SDDC allows providers to use the centralized data center infrastructure to deliver network services and resources to many different clients.
The reduced cost of hardware and storage has made SDDCs more appealing. Businesses can spend less to construct big data centers and then rent out the centers’ resources as infrastructure as a service (IaaS).
