A couple of weeks ago, I explored the migration to Unified Communications and gave my point of view about how the migration is somewhat determined by economics and the fact that enterprises have already set in place communications systems that have been paid for and work.  But let’s say that you as an enterprise have determined the time is right to move to UC.  Should it be premise-based or cloud-based?   Some enterprises are worried about losing control and want on-premise equipment.  But for many enterprises, UCaaS is the way to go as long as they are satisfied with the Quality of Service (QoS) and security.  And by now, so many enterprises have moved to cloud-based UC that there are more than enough use cases and proof points that QoS and security issues have largely been overcome.

UCaaS is a good way to go because adding features can be done as required.  Let’s say the basic UC features of email, voice, and presence/IM are in the system.  But there is a separate conferencing system to be migrated.  If the conferencing system works, you can keep using that as long as you want.  Then, when the time is right, move conferencing to the UCaaS environment.  Some UCaaS providers may also provide differentiation in the form of say video voice mail, or some other adjunct apps that may be useful for your business.

UCaaS could also be less expensive for your enterprise.  Various subscription pricing options are available, as are per minute plans. So it could end up being cheaper for sure.  But you should have an idea of your needs because you sign up for a price plan.  UCaaS could also bring a different mix of players than on-premise does.   Data center providers/cloud providers such as Google, Amazon, and HP could offer alternatives not available in CPE.
