Advantages of Cloud Computing
▪ Trade capital expense for variable expense
▪ Benefit from massive economies of scale
▪ Stop guessing capacity
▪ Increase speed and agility
▪ Stop spending money on running and maintaining data centers
▪ Go global in minutes
Cloud Computing Deployment Models
▪ Cloud (Model in which third-party provider makes compute resources available to the public over the internet)
▪ Hybrid (Model that includes a mix of on-premises, private cloud, and third-party public cloud)
▪ On-Premises (a model that uses the same legacy IT infrastructure runs cloud resources within its own data center)
