For many enterprises, the most recognizable model of cloud computing is the public cloud model, which provides ultimate scalability, flexibility, location independent access and is of course cost effective. But workload evaluation is important before an organization moves to the public cloud. There can be situations wherepublic cloud such as AWS costs may far exceed on-premise infrastructure costs. According to research firm Gartner, the evaluation every organization must undergo before moving into a public cloud consists of taking into account few major things. These are: number of machines an organization will run, number of hours per day or per week they'll run and the amount of storage these machines will generate. The evaluation should also include the licenses that need to be paid for on a recurring basis; how many times and how often snapshots occur; the rate of change in the data; and how much new data they are going to generate. Mike Ryan, consultant, Epitech, said that “You're paying for the elasticity of Amazon, and if you're not using that, it makes sense to bring things into your own data centre”. The scaling flexibility of public cloud is great during the growth phase, but which solution is the best from an enterprise long term perspective?
