13

Why many organizations are moving to the cloud V.S. why they are not

ARE: lower costs, ubiquitous access, improved scalability, elasticity, virtualization technology, internet-based standards enable flexible & standardized processing capabilities ARE NOT: when law or standard industry practive require physical control or possession of the data, financial institutions are legally required to maintain physical control over their data
