We are 100% cloud (sky actually)
Over the last 3 years we have migrated to 100% cloud - although we have gone beyond the cloud and call it sky IT.
Although only a small company (one location + some work at home, around 80 total users) we are an example of the future. In fact, since the management have worked for the biggest companies, we know that if we were a big company we could have done the same things at even lower unit cost and had the leverage to get the customization we have to live without.
In five years, no in house organization will be able to compete with the base services from MS, Google, Amazon, ... So, come and join us beyond the cloud; up here the deep blue sky looks beautiful every day.
