Software Defined Data Center (SDDC) is the next underlying technology, where software delivers greater levels of intelligence and value, on top of standardized hardware. A unified data center platform provides unprecedented automation, flexibility and efficiency to transform the way you deliver IT. Computing, storage, networking, security and availability services are pooled, aggregated and delivered as software, and managed by intelligent policy-driven software. Self-service, policy based provisioning, automated infrastructure and application, and business management are key benefits of this model. This would result in a data center optimized for the cloud era, providing unmatched business agility, highest SLAs for all applications with simpler operations and lower costs.
The way we have created our understanding of a SDDC is by taking into account the network, storage and computing aspects of a data center and view the whole system working together.
All infrastructure is virtualized and delivered as a service, and the control of this datacenter is entirely automated by software. The three major building blocks of SDDC are:
• Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels; each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time.
• Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.
• Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later.
Over the last few years, more and more IT professionals have been evaluating the possible benefits of migrating to SDDC. Some early adopters have moved beyond the evaluation stage to start planning and implementation.
