The year 2012 brought a significant amount of growth in enterprise use of cloud services but did it fulfill our expectations? With just five weeks left in the year, it’s time to reflect on our predictions for this market in 2012. Back in November 2011 we said that the cloud market was entering a period of rebellion, defiance, exploration, and growth, not unlike the awkward teenage years of a person’s life. The market certainly showed signs of teen-like behavior in 2012, but many of the changes we foresaw, it appears, will take several years to play out.
Out of all the inquiries I get from Forrester enterprise clients, the above question is by far the most common these days. However, the question shows that we have a lot to learn about true public cloud environments.
I know I sound like a broken record when I say this, but public clouds are not traditional hosting environments, and thus you can't just put any app that can be virtualized into the cloud and expect the same performance and resiliency. Apps in the cloud need to adapt to the cloud - not the other way around (at least not today). This means you shouldn't be thinking about what applications you can migrate to the cloud. That isn't the path to lower costs and greater flexibility. Instead, you should be thinking about how your company can best leverage cloud platforms to enable new capabilities. Then create those new capabilities as enhancements to your existing applications.
This advice should sound familiar if you have been in the IT business for more than a decade. Back in 1999 we did the same thing. As the Web was emerging, we didn't pick up our UNIX applications and move them to the web. We instead built new web capabilities and put them in front of the legacy systems (green screen scrapers, anyone?). The new web apps were built in a new way - using the LAMP stack, scaling out, and being geographically dispersed through hosting providers and content delivery networks. We learned new programming architectures, languages, and techniques for availability and performance. Cloud platforms require the same kind of thinking.
