Importantly, public cloud offerings can access services such as a choice of service providers or additional services offered by the cloud provider for additional networking requirements, such as software defined networking (SDN) and Network Functions Virtualisation (NFV).
From a trend perspective, we definitely believe that NFV and software-defined 'everything' will gain momentum. Globally, and specifically in Asia Pacific and Japan, exploration of NFV and software-defined technologies (network, virtualisation, data centre, storage and infrastructure) will evolve from being simply "research", and enterprises, particularly in the service provider space, will begin to roll out production deployments. With more user cases, we will likely see larger deployments commissioned.
As an industry, we are seeing a shift towards open, more flexible, efficient, highly programmable and elastic network infrastructure solutions with key initiatives such as OpenStack and the Open Daylight Project as well as disruptive technologies that will ultimately benefit organisations.
At the same time, we expect NFV to gain prominence and drive new revenue opportunities for service providers by pulling managed services into the cloud, drastically reducing costs and increasing service agility.
Although it may still be too early for full SDN deployments, a key decision making criteria for infrastructure will be to ensure that infrastructure will support SDN going forward. Open architecture will be key to this future-proof strategy.
