In 2015 we expect to see enterprises adopting a pay-as-you-use model for network connectivity too through network resource virtualisation. Service providers will drive the trend -instead of charging enterprises for a bulk package; with software-based networking technologies (like NFV), they can offer billing based on the enterprise's usage. We are already seeing some bandwidth-on-demand and virtual VPN services in the market today in the Asia Pacific region and can expect more in 2015 thanks to these software-based networking innovations.
4. Continued concern around data center security
In 2015 as more businesses go online and into the cloud it is unfortunately likely that the market may experience further breaches or denial-of-service attacks into data centres.
Security will remain a top concern among enterprises as they prepare to deploy cloud services. In fact, concern or lack of information about security is arguably the primary inhibitor for SDN adoption.
Much industry effort has already been put into the creation of a secure SDN environment while minimising the impact on flexibility, speed, functionality or control. Techniques have been developed that, with the proper configuration and integration, enable enterprises to secure an SDN environment without impact to SDN capabilities.
In 2015 we can expect to see an entire ecosystem of new network security capabilities emerge to address the new security challenges that SDN and NFV bring with them. This is clearly a space that will garner much industry focus and development.
5. Small cells and Wi-Fi Off-load become big news
2015 will be the year where small cell and Wi-Fi off-load deployments are more widely adopted by mobile operators to address network congestion as data-hungry consumers use LTE speeds to access multimedia content and services on mobile devices.
Mobile operators are looking to lighten the macro tower traffic load through the deployment of small cells and Wi-Fi - which will also significantly improve overall network coverage, especially indoors. As operators shift as much as 20 percent of their mobile traffic from the macro network into small cells by 2018 (Infonetics Research), the overall quality of user experience will improve significantly, especially indoors. As a result of improved coverage and download speeds, enterprises will drive a significant increase in traffic. Operators will need to act quickly to broaden 10GbE mobile backhaul connectivity between macro towers and small cell-metro networks.
