All service is in the cloud - use what you need; examples of email service, payroll, etc - application and data is in the cloud so you must know security
. Platform - somewhere in between - you don't maintain software or hardware - but you're responsibility for the development using their building blocks
. Sometimes called hardware as a service - basically using someone elses hardware - you are responsible for the software and data
. Your own cloud. Cloud available to everyone
. Part of the cloud is yours, but other parts are available to third parties
. Many organizations sharing the same resources in the cloud. Your hardware and software is at your location
. Cloud servers are elsewhere and may not even be yours
. Put data in the cloud and access it anywhere - very important that it's encrypted
. Puts all computing power in the cloud - op system on the local computer just needs to be able to run the software
. Integrates your local security policy and procedure with your cloud environment (it can be hardware or software)
. Moving all security technology to the cloud - pay only for what you use and scale up or down as needed - sits between you and the rest of the internet on the cloud
