Even after so many have begun evaluating and deploying cloud strategies, there are still debates raging on about what can be considered “Cloud” and what cannot. We have seen several examples of huge enterprises successfully combining both public and private cloud infrastructure services. They have not only been able to integrate them smoothly, but they are also building on the foundation easily with more and more services rolling out with increased ease and larger reach. There are two definitions of the cloud (as given in older versions of the Wikipedia definitions). They are two definitions that are different and similar at the same time. Sounds confusing? Well let’s take a closer look.
- Cloud as a business model- This is one of the earliest definitions that floated on the internet when the cloud was in its infant stages. The concept indicated that the cloud was a way of selling IT capability as services and this dates back to when Amazon introduced the S3 and EC2 services. It was described as a service that you availed over the internet and paid per use and it was ready for use on demand.
- Cloud as an operations model – This definition was introduced when the cloud was seen to penetrate into operations for businesses across the world. It held the view that the cloud was not something new but it was simply providing regular services on demand with elastic services. An enterprise that operates with this on demand criteria factored into their operations was described as a cloud service.
