Gartner: The top 10 strategic technology trends for 2012

Michael Cooney | Oct. 19, 2011
The technology that makes up many of the systems in the IT world today is at a critical juncture and in the next five years everything from mobile devices and applications to servers and social networking will impact IT in ways companies need to prepare for now, Gartner Vice President David Cearley says.

8. In-memory computing: We will see huge use of flash memory in consumer devices, entertainment devices, equipment and other embedded IT systems. In addition, flash offers a new layer of the memory hierarchy in servers and client computers that has key advantages -- space, heat, performance and ruggedness among them. Unlike RAM, the main memory in servers and PCs, flash memory is persistent even when power is removed. In that way, it looks more like disk drives where we place information that must survive power-downs and reboots, yet it has much of the speed of memory, far faster than a disk drive. As lower-cost -- and lower-quality -- flash is used in the data center, software that can optimize the use of flash and minimize the endurance cycles becomes critical. Users and IT providers should look at in-memory computing as a long-term technology trend that could have a disruptive impact comparable to that of cloud computing, Cearley says.

9. Extreme low-energy servers: What if you could turn 10 virtual machines in one box into 40 slow physical servers that are tiny and use very low amounts of energy? There is a call for this type of computing to handle big data. For example, thousands of these little processors could work on a Hadoop process, Cearley says. Gartner says that 10%-15% of enterprise workloads are good for this. Moving the application from 10 images to 40 slower, less capable machines will only deliver on that promise if the software will perform the same. Server technologies are going to change to handle big data.

10. Cloud computing: This topic went from No. 1 last year to No. 10 this year, but it's still an important trend. It will become the next-generation battleground for the likes of Google and Amazon. Going forward, enterprise IT will be concerned with developing hybrid private/public cloud apps, improving security and governance, Cearley says.
