Cloud storage allows you to save data and files in an off-site location that you access either through the public internet or a dedicated private network connection. Data that you transfer off-site for storage becomes the responsibility of a third-party cloud provider.
Cloud storage services provide elasticity, which means you can scale capacity as your data volumes increase or dial down capacity if necessary. By storing data in a cloud, your organization saves by paying for storage technology and capacity as a service, rather than investing in the capital costs of building and maintaining in-house storage networks.
