This system can include different types of computer
programs. Each application in this system is
managed by its own dedicated server. The back-end
side has some responsibilities to fulfill for the client
8. There are certain services and models working
behind the scene making the cloud computing
accessible to end user.
The working models for cloud computing:
1. Deployment models
2. Service models
9. Deployment model define the type of access to the
cloud. Cloud can have any of the four types of access:
1.Public cloud
2.Private cloud
3.community cloud
4.hybrid cloud
10. Sevice models are the reference models on which
the cloud computing is based they can be
categorized as:
1.Infrastructure as a service.
2.Platform as a service.
3.Software as a service.
11. Some of the cloud providers are:
Apple iCloud :5GB of free storage
Dropbox :2GB of free storage
Google drive :15GB of free storage
Amazon cloud drive:5GB of free storage
