A recent whitepaper by Research In Action found that 81 percent of businesses already do or will soon use cloud infrastructure or services. However, there are still some worries about the downsides of cloud computing.
Indeed, the report found that 79 percent of businesses worry about hidden costs and problems that could come along with the adoption of cloud technologies. These include performance availability, as well as cloud-based applications that could be more difficult to troubleshoot, and require more time and effort to manage the SLAs.
As we collect true life data points from enterprises that are deploying cloud computing, we find that the cost is typically a bit higher, and there are a few surprises, such as lagging performance. These are not reasons to push back on cloud computing, but they should be dialed into our expectations.
I suspect that more studies will come out that show some concern about the affect of cloud computing on IT shops that implement this technology. As always, with anything new, the hype will never equal the reality. Moreover, we still have a lot to learn in terms of best practices around the use of this technology.
