‘Cloud’ is a metaphor for Internet.

An Internet-based computing, that provides you

› On-demand resources like electricity.

› You pay as you go.

› Use only what you need, no extra expenditures.

Accessing computing resources that are owned and operated by a third-party service provider.

Concept evolved in 1950(IBM) called RJE (Remote Job

Entry Process).

In 2006 Amazon provided First public cloud AWS(Amazon

Web Service).

Idea that revolutionized cloud computing:

utility

computing

Gridcomputing

It has three components

1.) Client computers

2.) Distributed Servers

3.) Datacenters

Clients

Clients are the device that the end user interact

cloud.

three types of clients:

1.) Mobile 2.) Thick 3.) Thin (Most Popular)

Datacenter

It is collection of servers where application is

placed and is accessed via internet.

Distributed servers

Often servers are in geographically different

places, but server acts as if they are working next to

each other

Reduce the complexity of networks.

Do not have to buy software licenses.

Customization.

Cloud providers that have specialized in a particular area (such as e-mail) can bring advanced services that a single company might not be able to afford or develop.

scalability, reliability, and efficiency.

Info. at cloud are not easily lost.

There are major there types of services. There are

1. Software as a service

2. Platform as a service

3. Infrastructure as a service

Deployment models define the type of access to the cloud. These are:

Private cloud

Community cloud (Combined Cloud)

Public cloud and

Hybrid cloud

Lower Computer Cost Improved

Performance

Increased data

reliability

Universal document

access

Reduced software costs

Unlimited storage capacity

Improved document

format compatibility

Instant software updates

Advantages

Stored data might not be secure

Features might be limited

Does not work well with low-speed connections

Requires a constant Internet connection

Disadvantages
