Most everyone in the IT field today is aware of the availability of public cloud infrastructure from Amazon, Microsoft, Google, IBM/Softlayer, and others. Public cloud services are the most rapidly growing segment of IT according to Gartner and other industry analysts. The benefits of adopting public cloud are numerous, such as scalability, flexibility, and the ability to operate without capital expenditures. In many cases, relying on public cloud can be greener than a custom built datacenter.
For those with growing IT needs and not having room for expansion, migrating applications to a public cloud provider can be a quick, easy, and inexpensive way to deliver the functionality needed without spending a lot of cash up front on hardware.
