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.
• Microsoft Office Live Small Business
• Microsoft Online Services
• Amazon
• Google Apps
• Yahoo
• Sales Force
• Zoho
• Virtual VOIP
• 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
• Web Hosting ~$100 per year
• Cloud Server ~$500 - $1000 per year or
$0.20 per hour
• Content Management System for Web – free
Web page editor – free to $1000’s
• Online Office applications $50 per year
• VOIP telephony – from $15 unlimited national
calls/month
