Software-Defined Data Center (SDDC) Explained
Software-Defined Data Center (SDDC) Explained
Modern software-defined compute, also known as virtualization, is the first step toward the software-defined data center. CPU and memory are decoupled from physical hardware, creating pools of resources for use wherever needed. Each virtualized application and its operating system are encapsulated in a separate, isolated software container called a virtual machine (VM). Many VMs can be run simultaneously on each server, putting the majority of hardware capacity to productive use.
Network virtualization technology takes software-defined networking (SDN) to the next level by truly decoupling network resources from underlying hardware. In much the same way that server virtualization emulates a physical server within software, network virtualization emulates the components of network and security services in software. In this way, the virtualized network is provisioned and managed independently from your hardware. Physical networking devices simply become vehicles to forward packets.

VMware’s Software-defined storage (SDS) strategy is to evolve storage architectures through the pervasive hypervisor, bringing to storage the simplicity, efficiency, and cost-savings that server virtualization brought to compute. Software-defined storage abstracts the underlying storage through a virtual data plane, making the VM, and thus the application, the fundamental unit of storage provisioning and management across heterogeneous storage systems. By creating a flexible separation between applications and available resources, the hypervisor can balance all IT resources—compute, memory, storage and networking—needed by an application.
Per-application storage services
SDS applies at the VM level, allowing storage services to be tailored to the precise requirements of an application and adjusted as needed on a per-application basis, without affecting neighboring applications. Administrators are in complete control of which storage services, and therefore costs, are consumed by which application.
Rapid changes to storage infrastructure
SDS uses a dynamic and non-disruptive model, just as in compute virtualization. IT admins can precisely match application demand and supply at the exact time the resources are needed. Storage services become fluid—a little more for this application now, a little less for that one later.
Heterogeneous storage support
SDS lets you leverage existing storage solutions, such as SAN and NAS, or direct attached storage on x86 industry-standard hardware. With industry standard servers, the backbone of Hyperconverged Infrastructure, IT organizations can design low-cost and scalable storage environments that easily adjust to specific and ever-changing storage needs.

Unified Data Center Management Software
The fully virtualized data center is automated and managed by intelligent, policy-based data center management software, vastly simplifying governance and operations. A single, unified management platform lets you centrally monitor and administer all applications across physical geographies, heterogeneous infrastructure and hybrid clouds. You can deploy and manage workloads in physical, virtual and cloud environments with a unified management experience. IT becomes agile, elastic and responsive to a degree never before possible.
Infrastructure and applications services are requested via a self-service portal where authorized administrators, developers or business users can select services that comply with pre-defined business policies. Service delivery is highly automated. Logical infrastructure and application blueprints model services that can be deployed in any approved cloud environment. The right levels of resources are automatically allocated based on business requirements and service-level requirements. Workloads are dynamically and continually orchestrated and balanced as dictated by changing patterns of demand.
With a scale-out and resilient operations platform, administrators get control over performance, capacity and configuration management. Predictive analytics and smart alerts help identify and rectify potential issues before they impact service quality. Intuitive performance dashboards provide app-to-storage visibility across physical, virtual and cloud environments. Log management capabilities extend analytics to unstructured data, for better visibility and faster problem resolution. Over- and under-provisioned VMs are right-sized to balance service level requirements with resource utilization. Powerful capacity modeling identifies “what if” scenarios to anticipate and optimize future infrastructure spend.
CIOs and IT executives can demonstrate and compare the costs of complex initiatives and investments, including private and public clouds. Users can see the cost of service in the service catalog. Visibility and transparency of the types, cost and quality of IT services consumed by a business unit, enable show and charge back the quantity and types of IT services consumed. Industry benchmark data and reporting help compare IT expenses to peer companies and cloud service providers, for informed sourcing decisions that drive down costs.

Software-Defined Private Cloud: On-Premises in Your Data Center
VMware provides flexible paths for evolving to a software-defined private cloud that you deploy on your own physical infrastructure. Customers typically begin with VMware vSphere, and at their own pace, add software-defined networking and storage, and various elements of our comprehensive management layer. Alternatively, you can move up to a full-infrastructure solution, VMware vCloud Suite, directly from vSphere. Or extend your Software-Defined Data Center management to include other hypervisor platforms or public cloud services with the VMware Aria Suite purpose built for hybrid cloud.
Cloud Services from VMware Partners
Certified VMware partners offer an array of globally consistent, flexible and custom-tailored cloud services. These too are built on VMware software-defined technology, for compatibility with your internal data center, guaranteed service levels, auditable security and assured compliance.
