Cloud works , but like anything its about pre-planning and having the correct connections and resilience to support your requirements , i like it and its the future of things to come......you will have many mixed views on this , some down to people worrying about there job (install guys mainly i would assume) , then you have some who are in the .... its just a quirky buzz word that will pass ...the same people who thought the internet thingy would never catch on.
Our place does its own cloud offering on SME and enterprise avaya equipment , when you look at the uptime the cloud offerings win hands down , as the kit is in our data centre controlled by us, nobody can lean on the power off button , or spill coffee over the CPU , but again i stress its about ensuring the connectivity between your site and Mr Cloud is designed correctly and resilience is factored in at near the top of the list.
Then there is the cost factor ....charging by seat , rather than having massive capital exp is a bonus.
In some situations its just not the right fit ... but like i say i think its the way things are heading , having tin onsite will im sure dramatically reduce in the years to come.
