As people, technology and financial decisions are driving a move to cloud computing, the anticipated benefits are many.
Reduced IT infrastructure and maintenance costs, made possible by cloud approaches that include multitenancy — in which a single software instance serves multiple client organizations — and multi-instance — in which every customer gets its own software instance; both approaches allow resources and costs to be shared across a large pool of customers.
Greater business agility enabled by the increased scalability of IT infrastructure and the ability to provision technology resources on demand, as needed
The ability to provide workers with access to systems and applications regardless of their location or type of device they are using
Improved disaster recovery and business continuity, through the use of multiple, redundant sites offered by cloud services providers
Cloud Models: Public & Private Cloud
The cloud is not a one-size-fits-all proposition. Companies can choose from several types of services, including public, private and hybrid clouds.
