CLOUD COMPUTING

“Cloud Computing is an ON-DEMAND, SELF-SERVICE Internet infrastructure that enables the user to access computing resources ANYTIME from ANYWHERE.

“Cloud computing is a model for enabling UBIQUITOUS, CONVENIENT, SELF-SERVICEnetwork access to a SHARED pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.

ESSENTIAL CHARACTERISTICS

On-demand Self-service

Broad Network Access

Resource Pooling

Measured Service Rapid ElasticityAbility of user to sign-up and receive service without delay

Utility based billing i.e.

subscription based

Ability to access the

service through desktops,

mobiles, tabs etc.

Capability to cope with

demand peaks

Computing resources are

pooled to serve multiple

consumers using a multi-tenant model

SERVICES MODEL

Software-as-a-ServiceConsume

Platform-as-a-ServiceBuild

Infrastructure-as-a-ServiceHost

End-to-end IT solution hosted

on cloud is provided by a

service provider to user on

subscription basis

Application platform hosted

on cloud is provided service

providers for development of

solutions

Cloud infra is provided to client

for deploying application

platform, building solution & using

as data center

EX:Groupon, Google doc, Quickbooks, Salesforce.com

EX:Force.com,

Heroku, Facebook,

Google Apps, MS Azure EX:

Amazon EC2

DEPLOYMENT MODELS1 2

3 4

Private Cloud: Resource managed and used by an organization

Public Cloud: Resources available to the general public over the internet

on a pay-as-you-go basis

Community Cloud: Resource shared by several organizations with common concerns

Hybrid Cloud: Resources partly managed by the service providers

and partly by the organization

EX:MS Azure

EX:Amazon EC2

EX:IBM Juniper

EX:Google GovCloud for LA

city council

ADOPTION ISSUES 1 2 3

Availability Security & Privacy

Support

Vendor lock-in Compliance

Impossible to provide 100%

availability, unless a high availability architect

Nearly impossible to

guarantee 100% security

and privacy protection

Both enterprise users and end users require support for

problem resolution

Vendor lock-in is a concern that the users always

have but in practice they

livewith

Enterprise users must maintain business legal

documents and assure their

integrityin order to

comply with various laws, such as SOX
