Cloud services have revolutionized computing, not least through IaaS, PaaS, and especially SaaS, which have allowed businesses to develop virtualized IT infrastructure and deliver software through the cloud, independent of a user's operating system.

Even better still, businesses can also mix and match cloud services from different providers through cloud brokers to ensure these services work to maximum efficiency and cost effectiveness, but also to reduce the chances of vendor lock-in while also improving redundancy. This may require additional cloud management software, but for larger businesses the economic benefits can be significant.
