Top 5 IT Trends/Predictions for 2015

Network functions virtualisation takes off, even without SDN

2015 will see continued development of SDN technologies, and buyer confusion will not abate as the incumbent switch and router vendors jockey for position. But NFV, already being widely deployed into service providers, will make its way into "classical" enterprise networks without the need for any SDN refresh (which, curiously, may require new hardware). Virtualised network functions allow organizations to dynamically provision networks wherever they're needed, on an on-demand basis, independent of any underlying fabric.

Data breaches grow larger and more frequent

Unfortunately, the relentless pace of data breaches in 2014 will continue in 2015.

Traditional security tactics, such as relying on "hardened" perimeters and rigid mobile device management will have little effect at slowing down the bad guys. Enterprises should shift investments and spend more on detection and response. Visibility across all applications, networks, and devices is the first critical step toward improving overall security posture. Establishing a baseline of what's "normal" helps to better isolate actual threats and respond accordingly.

Hybrid architectures become the norm

Even though cloud computing and third party hosting will continue their rapid expansion, on-premise IT will remain a reality for 2015 and beyond. The resulting hybrid infrastructure stack will create challenges for most organizations-including architectural "collisions," where design patterns for on-premise development and deployment don't translate well (or at all) into cloud. Working through these challenges will require more sophisticated models, policies, identity/access controls, and coding practices to ensure that end-user needs are met consistently across all platforms.
