Starting in the year 2013, many companies began building their way towards software Defined Data Centers with virtualization. Up until then, data centers traditionally didn’t have the capacity to accommodate total virtualization.
But, what are they?
Software-Defined Data Center architecture, or SDDC, is a data center in which its infrastructure elements, such as CPU, security, networking, and data storage, are completely virtualized and is offered as a service. Control of the data center is totally automated by software, so the hardware configuration is managed through smart software systems, whereas in traditional data centers, their infrastructure is generally limited to hardware.
In short, memory and CPU are detached from any physical hardware, making way for many resources to use when needed. Each application and its OS are divided in Virtual Machines, and each Virtual Machine can be run at the same time. This offers more availability, higher performance, and noticeable savings, putting the majority of hardware capacity to productive use.
What are their components?
Software-Defined Data Centers have many core components, but the most important of them are:
Software-Defined Storage that merges physical storage from multiple network devices, creating a unified storage device managed from a central console.
Software-Defined Networking that works by merging software, hardware, and networking functionality, into a software-based virtual network.
Automated management and software that gives an administrator the power to provision manage and control all data-center components that are software-defined.
What are their benefits?
The use of Software-Defined Data Centers can be used as a tool to dynamically manage and provision applications, IT resources, and infrastructure. This way, any virtualized component will modify aspects like security, priority, and urgency, in an automatic manner.
Software-Defined Data Centers are designed to allow data centers to be managed as a unified system. They also provide any organization with a private cloud for a better control of their own hosted data.
Software-Defined Data Center architectures are also practical and flexible thanks to their cloud computing system since any workload can be processed everywhere and used instantly by any kind of personal computer, virtual desktop, or portable gadget.
