The Cloud or Cloud Computing is simply put the outsourcing of computing power traditionally maintained in a on premises data center. Rather than establish your own data center you can purchase the operations of a vendor’s data center. Those vendors are many these days, but the largest are Amazon AWS, Microsoft Azure, and Google Cloud. We will go more into these specific vendors in the future.
You might be asking yourself “that is all good and great but what does all that have to do with cloud computing?”
The key words from that long-winded explanation are “innumerable products and services rely in some way on technology, measurement, and standards provided by NIST” In short NIST will provide you with standards that can be referenced. NIST is commonly referenced in cyber and now cloud.
NIST publishes standards in papers known as “special publications”. The “The NIST Definition of Cloud Computing” paper is also known as special publication (SP) 800-145.
This special publication is authored by Peter Mell and Timothy Grance of the National Institute of Standards and Technology (NIST). I will include the publication link in the show notes, and I highly recommend reading it.
For now, I’ll read the definition of cloud computing directly from this publication since it lays such a critical foundation.
