Plugging in to complex, expensive data centers someone else builds and maintains should also be easy, unless you want it to do what you want it to do, rather than just sit there, blinking its lights, spinning its disks and waiting to be told what to do.
Choosing, installing, customizing, securing and connecting data to applications you would like to sit in a cloud maintained by Microsoft or Amazon or Rackspace is a lot less work than it would be in your own data center with software you have to write yourself.
It still takes a lot of work.
Guess what? Technology isn’t magic; it’s mechanics
If you want to rent a whole data center instead of just space for a few of your own apps and servers, it takes just as much work to design, configure and implement as it would if you were doing it in your own data center. It may be cheaper and easier in the long run because you’re not spending nearly as much capital to buy the hardware, hire the data-center crew to maintain it or even commit long-term to much of the cost.
It will certainly be a lot less work than building your own data center, and may work better, more efficiently and with better performance than you can manage.
It will not stay up 24 hours per day, 365 days per year, forever.
It will not run without losing a bit of data, exposing you to a shred of risk of data breaches coming from either inside the organization or outside, or requiring that your technology staff spend a lot of time tuning the networks, hardware, securing the data, writing custom interfaces, queries and functions for end users.
The cloud will not eliminate the headaches or work IT has always done to make boxes filled with semiconductors do things that seem important to people who don’t even know where the servers live.
If you design it correctly, if you implement it well, if you train your staff to manage the resources that go into your system, cloud computing can make IT far more powerful without necessarily having to build or buy a lot of extra power.
It can let you push computing power at apps that suddenly become memory hogs, see where the heavy users of data or applications really are and move both to locations physically closer to them – slashing lag time without changing a thing about how the apps or data work.
Disappointment caused by contradictory expectations
Symantec’s survey shows three quarters of organizations are talking about moving to cloud computing in some form, though only 20 percent have finished even their initial cloud projects.
Eighty eight percent of those surveyed said they expected cloud would make them more agile.
Only 47 percent found that to be true.
