An Open Source Cloud Solution, for use with your own hardware. Unlike Google Compute Engine (Google Cloud) , Amazon Web Services (AWS) and Azure (Windows Cloud), Open Stack is not a public cloud. Instead, it is a private cloud, which you can install, configure and use with your own existing hardware.
If you’ve already got your own datacentre, or you’re intrigued by the cloud, but not so impressed with the public cloud solutions available to you at the moment, then Open Stack could be for you. Rather than being something that’s exposed to the web by default and only protected by layers of software, Open Stack is instead a fully featured virtualisation solution, designed with cloud technologies in mind from the start, for the more discerning early adopter.
With Open Stack, whilst the initial outlay can be higher, if you don’t currently have the hardware to run it on this is, the long term TCO (Total Cost of Ownership) figures are much more palatable, than some of the public cloud costs that can be incurred.
