I wrote the following text in 2013, but today it’s still very actual:
Cloud computing, it was a hype a few years ago and a lot of companies understood what it could do with their business. The big ones like VMWare, Amazon and Microsoft created a complete new business around it and they benefit from it right now.
A lot of people don’t understand the cloud yet or they have a complete other meaning for it. If I ask 10 System Engineers or 10 sales people following question “What is the cloud”, I’ll get 10 different answers.
“Cloud is a way for people to have access to their systems via a single sign on system”
“Cloud is when people can manage servers via a website”
“Cloud is when I start my pc in an airplane, while flying”
“The practice of using a network of remote servers hosted on the internet to store, manage or process data, rather than a local server or personal computer”
There are a lot of different answers, even funny ones but cloud means business, big and serious business!
My opinion about the cloud is very easy and goes back from before the hype. It started in the seventies on a complete different platform and with total different hardware. I’m convinced that Cloud is a new name for creating new business with an old idea.
The old Idea
For a lot of people, cloud computing is new, it started around 2008 and is now a fully mature business model but the cloud I speak of isn’t invented by companies like Amazon or VMWare, but it’s used in unix environments for more than 40 years!
In Unix, you were able to create your own “virtual servers” by adding cpu’s, memory and disks to a single unix system. This flexibility of creating those systems is in my opinion the only real cloud. It wasn’t called cloud at the time. IBM’s name for it was a Logical Partition or an LPAR.
Cloud computing is a flexible way to assign system resources to a single virtual system.
