Topics Discussed:


-Cloud computing

-Other trends in Web technologies

-Teaching strategies and opportunities.

Cloud characteristics:

-Shared resources

-On demand


-Usage based metering

-Networked access


1)Business delivery benefits:

-IT resources can be leveraged optimally to serve fluctuating business needs

-Improved Agility

2)Infrastructure management benefits:

-Cost savings in designing, provisioning and delivering new services.

-Cost estimation through standardization and reuse of IT infrastructure.

-Reduced human error.

Cloud flavors:

1) Public cloud:

      A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.

The main benefits of using a public cloud service are:

-Easy and inexpensive set-up because hardware, application and bandwidth costs are covered by the provider.

-Scalability to meet needs.

-No wasted resources because you pay for what you use.

2) Private cloud

    Private cloud (also called internal cloud or corporate cloud) is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall.

3) Community cloud

    A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, such as Amazon Simple Storage Service (Amazon S3) for archived data but continue to maintain in-house storage for operational customer data. Ideally, the hybrid approach allows a business to take advantage of the scalability and cost-effectiveness that a public cloud computing environment offers without exposing mission-critical applications and data to third-party vulnerabilities.

4) Hybrid cloud:

     The community cloud is a cloud infrastructure that is shared by several organizations and supports a specific community, such as healthcare, that has shared concerns around mission, policy and compliance considerations.

Delivery modes:

-Infrastructure as a Service (IaaS)

-Platform as a service (PaaS)

-Software as a Service (SaaS)
