Meteoric pace with which technologies are evolving distress enterprises for increasing infrastructure cost and maintenance. Most of the recent market bombarding technologies demand larger infrastructure provisioning, deployment and expenses thus require more resources and maintenance affecting abruptly the final ROI. Imagine the evolution from physical computers to virtualization, DevOpsSec, Dockers-containers, CRI-O, Kubernetes, microservices architecture and service mesh implementation. Many enterprises, at this moment, are hesitant to make a quick decision whether to invest to cope with technology change or to keep dragging enterprise with the current implementation that they have.
Hardware-defined infrastructure comprised of servers, network cables, routers, switches and such other aspects of a typical data centre drive what software solution is going provide. Expansion of infrastructure demand thinking on each of the individual components that construct a data centre.
Software-defined infrastructure conceptualize and encompasses all of the components mentioned in the above paragraph. A centralized API console contributes and administers operations and management of each component providing benefit to managing from one central platform.
Visualize a Hardware-defined data centre as a room containing infrastructure components when full, we are stuck. On the contrary, software-defined data centres would have dynamic footage and we can scale as per claims come forth. We would not be bounded by the physical characteristics of resources available. This is the beauty of software-defined data centres, which in turn encourage embracing SDDC architecture and gaining eventual digital transformation capabilities through its implementation.
Having core data centre components virtualized and enclosed in a container contribute to centralized management through one platform certainly providing ultimate agility, reliability, security, and scaling automatically accommodating outpouring workload scenarios and optimized performance. An appropriate implementation of SDDC would discover and accommodate spikes in workload preemptively and scale automatically. As the control of the software-defined data centre automated by software leveraging hardware configuration through intelligent software subsystem.
A perfect example of a software-defined network is Kubernetes SDN or OpenShiftSDN that administer automatic IP and port assignment to each pod/container/service that spins up and de-allocates those when destroyed.
Kubernetes is leveraging the software-defined networking that brought a plethora of advantages and is the epitome of modern networking. In the same way, SDDC would contribute to making data centre services easy and inexpensive to configure, manage and reducing the need for manual human intervention utilizing ultimate automation.
