One of the most promising IT architecture trends that has been gaining tremendous popularity amongst data center operators of late is the software-defined data center approach.

This technique definitely ushers in a plethora of benefits for those within the industry, and is considered as the future of data centers. According to industry pundits, it has been projected as inevitable, and a next step on the pathway to it is the virtualization of network.
Simply put, software-defined data centers are more agile, secured, and highly resilient comparatively to new HDDC (high density data centers) architecture set forth by the prime network service providers today, at one-third of the cost.

Through this post, I would be discussing in detail about what exactly software-defined data centers are and how can data center operators leverage this new technology?

Software-Defined Data Center (SDDC):

SDDC is an arrangement that is being fabricated for the storage of data, similar to the way as many traditional data centers are doing. However, it leverages entirely virtualized systems which are then delivered as a service to the clients by the vendors. This comprises of everything right from networking to storage to CPU and security of highly sensitive information.

There are basically three key attributes that make up a software-defined data center:

- Network
- Storage and
- Server virtualization

In the aforesaid arrangements, a virtual environment is created for enhanced utilization of available resources and abridged dependency on hardware components. A software-defined data center enables end users to make the most of on-demand services as and when required. Largely, a capability of this sort is usually backed by highly intuitive software that virtualizes resources, combines them together with facility and disseminates them to varied applications as they are needed. This basically creates a private, virtual data center for each customer.

How Operators can make most of the newly emerged software-defined data centers?

One of the compelling benefits of the SDDC is the capability to drive in improved utilization of available resources allied with networking and storage processes. Through it, the operators can gain a clearer idea about the available capacity within a software-defined data center, and can get rid of silos simply by sorting out storage and network interfaces and hardware.

Thanks to its design, a software-defined facility thwarts the subsistence of underutilized equipment and ensures that all servers are effectively utilized. Furthermore, this will definitely bolster data center sustainability efforts, as by making use of fewer systems at a superior level of utilization helps in plummeting both electricity and cooling costs.

Shifting to Data Center into the Future: Key Data Challenges

As data centers persist to evolve in response to ever-increasing client requirements, many industry analysts are now considering software-defined facilities the future of the data center realms.

According to the reports projected by Forrester, the concept of data center resources through a software-defined facility is the future of IT architecture.

As more such arrangements take steps towards this design, there are compelling challenges that need to be addressed, such as the growing data levels that are at present creating substantial market growth. At present, near about 50 to 70 % of on-premises servers are virtualized. Nevertheless, this might not be sufficient to sustain expected data growth in future. Well, it has been estimated to reach near about 40 zetabytes within the coming 6 years. Consequently, data center operators are expected to work speedily to bring in their facilities into the future by doing away with bequest hardware and set up virtualized environments to cater to mounting data requirements.
