Over two thirds (around 70%) of the Earth’s surface is covered by water, mostly the oceans. So, when it comes to thinking about universal coverage for wide area networks (WAN), there are some challenges. Undersea cables make fine point to point connections, but do not provide maritime connectivity on the sea surface in between. So…
Two data processing trends are joining hands and moving towards wider availability for SMEs: hyperconverged data centre infrastructures and software defined WAN (SD-WAN) connectivity. What was just a year ago a daunting deployment and management challenge has now been packaged and centralised. This allows for much easier adoption into SMEs with cloud application and enterprises with branch environments.
Both concepts have similar development drivers behind them. The data centre hyperconvergence concept originated in large cloud companies like Amazon, Facebook and Google. They placed an emphasis on low-cost, ease-of-use and rapid self-service that can link WAN-connected sites of very different sizes and capacities. They tried to use existing data centre architectures, but quickly realized that they were a poor match for their demands.
