3. Cloud Computing
• Cloud computing is the delivery of different services through the Internet.
• These resources include tools and applications like data storage, servers,
databases, networking, and software.
• Rather than keeping files on a proprietary hard drive or local storage device, cloud
based storage makes it possible to save them to a remote database.
• As long as an electronic device has access to the web, it has access to the data and
the software programs to run it.
5. Public Cloud
• Public cloud is open to all to store and access information via the
Internet using the pay-per-usage method.
• In public cloud, computing resources are managed and operated by the
Cloud Service Provider (CSP).
6. Private Cloud
• Private cloud is also known as an internal cloud or corporate cloud. It is used by
organizations to build and manage their own data centers internally or by the third
party.
7. Hybrid Cloud
• Hybrid Cloud is a combination of the public cloud and the private cloud. we can
say:
• Hybrid Cloud = Public Cloud + Private Cloud
• Hybrid cloud is partially secure because the services which are running on the
public cloud can be accessed by anyone, while the services which are running on a
private cloud can be accessed only by the organization's users.
8. Community Cloud
• Community cloud allows systems and services to be accessible by a group of
several organizations to share the information between the organization and a
specific community. It is owned, managed, and operated by one or more
organizations in the community, a third party, or a combination of them.
