Communications is moving to the cloud. That should be obvious to everyone at this time. What’s less obvious is that the definition of cloud is changing.
In reality, cloud has been constantly evolving since the early 2000s. The first wave of cloud was akin to a hosted service where cloud providers did a “lift and shift” of a big PBX and moved it into a hosting center. There were only two cloud-like things about these UCaaS and CCaaS providers: their infrastructure on the company premises and customers could shift to a subscription model.
