Everyone’s favorite phrase now is “Cloud is just a marketing
term, what you mean is IaaS, SaaS, PaaS, etc.” but I strongly disagree. If anything all of the “aaS” are the
marketing terms and the Cloud is the technical term. Stick with me and I’ll explain why…
"Cloud" is a technical term
When studying for my CCNA in 2002 we often came across an
icon that looked similar to the picture on the right. For about a week folks were so baffled by
what the “cloud” was. It represented
anything not on the network. It could be
the internet, and ISP, or some other infrastructure which couldn’t be defined
because we had no visibility into the environment.
At this point Cloud was a TECHNICAL term. Once we understood that whatever was in the “Cloud”
could be anything we moved on to learning more important things. “Cloud” represented everything we were not
directly responsible for or what we also called “AMP” (ain’t my problem).
I agree and accept that the "Cloud Computing" (IaaS) concept has been around since the 1950's and it was then called "time-sharing" on mainframe computers. Mainframe time-sharing is similar to cloud computing but they were not the same technically. These mainframes lived onsite or nearby and where physically shared either by workstations/users where now resources are logically shared and are off the local network. This was not in the "Cloud". The comparison should really be between time-sharing and virtualization. Virtualization is what has made IaaS possible.
Back to the future
Fast forward to present day and what’s changed? Not much. The cloud is still the same, we just use it differently and it is more widespread. Instead of just being network infrastructure for which we aren’t responsible, it could be computing, software, or everything our businesses are built on. To me the cloud is still a technical term, albeit a very vague and all encompassing technical term, but that was the original intent for the term. In actuality all of the “PaaS, IaaS, UCaaS, DRaaS, etc are the marketing terms.
I don’t have a problem with marketing. I believe it plays an important role in
taking complex ideas and breaking them down into bite sized information the
majority of folks can understand. Since
the cloud is vague “as originally intended” we need easy to remember buzz words
to help us define different aspects and uses of the cloud.
So I beg you, please stop being “that guy/girl” on forums
who feels the need to point out the “Cloud” is just a meaningless marketing
term used to describe technology used in the 1950's, you are wrong.
