Term Cloud is used as a metaphor for Internet.

Cloud Computing is Internet-based computing,

whereby shared resources, software, and information

are provided to computers and other devices on

demand.

"In effect the cloud is network virtualization."

Concept generally incorporates combinations of the

following:

Infrastructure as a service (IaaS)

Platform as a service (PaaS)

Software as a service(SaaS)

Cloud computing customers do not own the physical infrastructure, instead rent

usage from a third-party provider. They consume resources as a service and pay

only for resources that they use.

Cloud computing users can avoid capital expenditure on hardware, software,

and services since they pay a provider only for what they use.

Dynamic provision of services/resource pools in a coordinated fashion.

On demand computing No waiting period

Location of resource is irrelevant

Activate, retire resources.

Dynamically update infrastructure elements without affecting the business.

Cloud Computing Layers

A Cloud client consists of computerhardware and/or computer software that relies on

cloud computing for application delivery.

Such as Computers, Operating systems,

Browsers, etc.

TheServers layer consists of computerhardware and/or computer software products that

are specifically designed for the delivery of

cloud services;

Including multi-core processors, cloud-specific

operating systems and combined offerings

Cloud computing - Characteristics Agility On demand computing infrastructure.

Linearly scalable challenge

Reliability and fault tolerance

Self healing Hot backups, etc

SLA driven Policies on how quickly requests are processed

Multi-tenancy Several customers share infrastructure, without

compromising privacy and security of each of the customers data

Service-oriented compose applications out of loosely coupled services. One

service failure will not disrupt other services. Expose these services as APIs

Virtualized decoupled from underlying hardware. Multiple applications can

run in on one computer.

Data, Data, Data

Storage, security, and synchronization.

PROS VS CONS Governance

Security, Privacy and control SLA guarantees Ownership and control Compliance and auditing

Reliability Good service provider with 99.999% availability

Cloud independence Vendor lockin? Cloud provider goes out of business Data Security Cloud lockin and Loss of control

Plan for moving data along with Cloud provider

Cost? Simplicity?

Tools Controls on sensitive data? Out of business

Big and small Scalability and cost outweigh reliability for small

businesses Big businesses may have a problem
