A 'cloud' is an elastic execution environment of resources involving multiple stakeholders and providing a metered service at multiple granularities for a specified level of quality (of service).

A cloud is a platform or infrastructure that enables execution of code (services, applications etc.), in a managed and elastic fashion.

Cloud computing is a general term for anything

that involves delivering hosted services over the

Internet.

Cloud computing can be described as a

combination of virtualization servers providing

scalable services, applications, storage and

infrastructure for multiple clients over the

Internet.

Cloud Computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand.

Clouds broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).

Infrastructure as a Service (IaaS) also referred to as Resource Clouds, provide (managed and scalable) resources as services to the user.

IASS-they basically provide enhanced virtualisation capabilities.

Examples: Amazon S3, SQL Azure.

Platform as a Service (PaaS), provide computational resources via a platform upon which applications and services can be developed and hosted.

PAAS -typically makes use of dedicated APIs to control the behavior of a server hosting engine which executes and replicates the execution according to user requests (e.g. access rate).

Examples: Force.com, Google App Engine. Software as a Service (SaaS) is referred to as

Service or Application Clouds are offering implementations of specific business functions and business processes that are provided with specific cloud capabilities.

SAAS-provide applications / services using a cloud infrastructure or platform and standard application software functionality is offered within a cloud.

Examples: Google Docs, Salesforce CRM, SAP Business By design.

Private Clouds are typically owned by the respective enterprise and or leased.

Functionalities are not directly exposed to the customer.

Software as a Service from the customer point of view.

Example: eBay.

Public Clouds. Enterprises offer their own services to users outside of the company. Providing the user with the actual capability to exploit the cloud features for his / her own purposes.

Allows other enterprises to outsource their services to cloud providers, thus reducing costs and effort to build up their own infrastructure.

Example: Amazon, Google Apps, Windows Azure

Hybrid Clouds. Though public clouds allow enterprises to outsource parts of their infrastructure to cloud providers.

It consist of a mixed employment of private and public cloud infrastructures .

Others clouds are Community Clouds, Special Purpose Clouds etc.

• Rapid deployment of services. Deployment in 1 day is possible. Quicker testing cycles.

• Less money needed for on site hardware, administration and maintenance required.

• Less capital expenditure. • Application access is independent of operating

system, Internet browser and computing device type.

• Scalable to handle variable business needs. • Access to large expensive hardware and

services with little costs.

• Electricity costs for local servers is saved in a cloud environment. Virtual cloud servers save on electricity by sharing.

• Disaster recovery from a local event. Easy to set up quickly in a new location.

• Data access independent of location or device. E.g. Home, work or while traveling.

• Telephony can also now be hosted. • National Fibre Broadband Internet access will

allow more access to cloud computing. • Save about $1000/year in electricity for each

physical server (including cooling) by not deployed locally.

• Storage costs are shared which can lower client level fees.

• Lower data centre Less space, cooling, UPS and generator requirements.

• Monthly fees • Business data is stored off site. • What happens to your data if your provider goes

out of business? • If the Internet is down locally then Cloud

applications may be unavailable. Some offline synchronizing application options exist.

• Encryption of data transmission and storage needs to be considered.

• Training of programmers with cloud standards. • Intellectual Property stored off site. • Cloud computing may not be economic in large

organizations
