Cloud Computing | 18/10/21
Public Clouds
Services are available to the public at large over the
internet.
Private Clouds
A private network used by one customer for whom data
security and privacy is usually the primary concern.
The downside of this type of cloud is that the customer will have to bear the significant cost of setting up and then maintaining the network alone.
Hybrid Clouds
Are often used where a customer has requirements for a mix of dedicated server and cloud hosting.
In such circunstamces the organization may choose to store
some data on its dedicated server and less sensitive data in the cloud.
A reason is where an organization needs more processing power than is available in-house and obtains the extra requirement in the cloud.
Community Clouds
Usually exist where a limited number of customers with similar "it" requirements share an infrastructure provided by a single supplier.
The costs of the services are spread between the customers so this model is better, from an economic point of view, than a single tenant arrangement.
Refers to the delivery of computing resources over the Internet.
Instead of keeping data on your own hard drive or updating applications for your needs, you use a service over the Internet, at another location, to store your information or use its applications.
Examples:
a) Online file storage
b) Social networking sites
c) Webmail
d) Online business applications
