Look out George! Next time, you might get hit by an EMC backup server falling out of a cloud.
Just before the piano fell
Companies seem to have voted with their feet and EMC recently announced they are pulling their “Cloud backup service” Atmos out of the Cloud because not enough customers are interested.
Why on earth would one need Cloud backup if one has Cloud applications!? In fact, come to think of it, EMC should be offering the exact opposite: old fashioned physical backup for Cloud applications…It just goes to show that Cloudwashing isn’t enough. Before you put something in the cloud and offer it to your clients, one would be advised to check whether there is any demand for it.

An IBM 370-168 mainframe, state of the art in the early 80's
Should we be calling IBM Big Green?
So here we are back to 40 years ago when IBM’s revenue mainly came from renting computer power to customers who connected their thousands of 5250 or 3270 terminals to mainframes using unbelievably slow modems that were each the size of a small desktop computer.
At the time, I was a Computer Science student and spent some time as an intern at IBM France. I participated in installing what was then the largest mainframe in France: an IBM 370/168 (it later became the zSeries) that had a whopping 512 Megabytes of RAM (yes kids…512Mb…stop laughing please…) and stacks of 3330 removable hard disks that could each store 200Mb of data on 8 platters (stop LOL).
Guess what: IBM has just announced they are reviving their System z strategy with the zEnterprise 196.And nobody is laughing this time.
What has changed?: it has 3 Terabytes of RAM,up to 96 processors, reams of blades and can manage loads of P and X servers. IBM says 30% of all servers are running Linux, and that the zEnterprise should soon support Windows clients. 40 years ago, the internal bus of an average computer probably ran slower than today’s high speed ADSL, SDSL etc…(why have you stopped laughing?)
Although total cost of acquisition (TCA) will be higher then for servers, TCO is lower within 3 years. Not to speak of the green side of things, these machines are much more energy efficient than a pile of servers.
If you still think Cloud Computing is a pie in the sky, think again because IBM certainly want to be at the forefront of the next paradigm shift.
