Over the last decade, huge growth in demand for Internet and mobile services has driven rapid transformation in digital businesses. This growth has been highly disruptive, and it has created new business opportunities and challenged the status quo. In the data center, two forces have created much of this change: the evolution of virtualization and the rise of cloud computing.
Latest-generation technologies in computing hardware and software platforms, including but not limited to unified computing, pervasive virtualization, containerization, new rack designs, disaggregation of compute resources, improved telemetry and analytics have all added to lowering the total cost of ownership (TCO) but also greater return on investment (ROI). This has set the stage for agile infrastructure and a further explosion in the number and type of instrumentation metrics available to today’s data center managers.
Optimization, as applied to data centers, means always having the right amount of resources, to cost-effectively enable the business use of those data centers. Right resourcing means, in effect, enough to get the data center “job” done, but not so much as to waste money. Everything from enough power and floor space to enough “computes,” and everything else. Easily said, but increasingly challenging to accomplish.
