When large enterprises move to a public infrastructure cloud (such as Amazon Web Services or others), it is a gradual, and often times, carefully measured process. Large enterprises strive for 100 percent certainty that the migration process will not impact the business; therefore, they’ll usually start slowly, by migrating one application or process to the cloud.
This is where hybrid clouds kick in. Hybrid clouds offer (just as their name insinuates) a hybrid between on-premise and cloud infrastructure. But once even part of the business is in the cloud, the need arises for cloud security. As data is migrated away from the local “safe” data center, access to the information is no longer controlled by the enterprise, and different, cloud-oriented, security measures must be considered.
