Public and Private Clouds

Typically, cloud computing platforms can be public or private. In the public cloud, the infrastructure and applications are owned by the cloud vendor and essentially leased to the cloud consumer. A private cloud operates behind an organization’s firewall and is maintained within the parameters of the host organization, although the infrastructure and applications can still be owned by a cloud provider. Private clouds are becoming increasingly more popular.

 Many believe that the “sweet spot” for cost optimization in the cloud relies on a delicate balance of public and private clouds – often referred to as a hybrid solution. For cloud GIS users, this means taking advantage of GIS software and services within on-demand infrastructures, taking full advantage of both on-premise and off-premise, depending on the business needs or restrictions of the organization.
