Software Defined Data Centers

What is SDDC (Software Define Data Center)?

Infrastructure in a traditional datacenter is typically defined by hardware and devices. It comprises of thousands of different applications, running in a mixed hardware environment using multiple management tools. One of its key characteristics is frequent application patching and updation to handle complex workloads based on multiple architectures. The flip side, however, includes multiple issues like underutilization of resources. These further have a rippling effect across multiple investment and effort expended areas including energy consumption, management costs, software licenses and data center outlays.

The concept of Software Defined Data Center (SDDC) to overcome the inefficiencies of traditional data centers and to deliver greater value to business. According to VMware, SDDC is "A data center platform that can be dynamically configured to meet the needs of any and all application workloads, all operating at peak levels of efficiency and automation".

Software Defined Data Center aims to abstract intelligent software from standard hardware by separating the control plane (configuration, topology awareness, management, operations) from the data plane (movement and storage of data). In this type of data center, the virtualized compute, network and storage layers along with their application and management components ideally exist only as software. The application layer is completely independent of the hardware layer in an SDDC. The core components of an SDDC are network virtualization, server virtualization and storage virtualization. It also has a business logic layer to translate application requirements, SLAs, policies and cost considerations. In this kind of data center all elements of the infrastructure — networking, storage, CPU and security – will be virtualized and delivered as a service. The provisioning and operation of the entire infrastructure is driven by software

Future of SDDC

Estimates from leading industry player IDC indicate that the services revenue which SDDC is going to throw open will be around $5.6 billion by 2016. With the advancement of technology, SDDC will move towards true hardware agnosticism and much higher agility in terms of dynamically handling, provisioning and managing rapidly changing workloads. The ease of use and simplicity that will be offered by this technology will definitely need a lot of un-complication effort. Whichever vendor perfects this technology is sure to get a substantial chunk of the services revenues unsheathed by SDDC.
