1969 – Leonard Kleinrock, ARPANET project

“As of now, computer networks are still in their infancy, but as they grow up and become sophisticated, we will probably see the spread of “Computer Utilities”, which, like present electric and telephone utilities, will service individual homes and offices across the country”.

During the last 40 years, several advances have taken place in both “computing” and “communications” areas that are turning the vision of “Computer Utilities” in to a reality.

Grid Computing Enables sharing, selection and aggregation of a wide

variety of geographically distributed resources for solving large scale resource intensive problems.

Ease of use and reliable.

Cloud Computing Promises reliable services through data centers that

are built on compute and storage virtualization technologies.

Users can access data from “Cloud” anywhere on demand.

Cloud is robust and available anytime.

Grid & Cloud Computing

Web Trends

"A Cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualised computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers.”

SLA = {negotiated and agreed QoS parameters + rewards + penalties for violation of agreement....}

Cloud Deployment Models

Private/Enterprise Clouds

Cloud model run within a company’s own Data Center / infrastructure forinternal and/or partners use.

Public/Internet Clouds

3rd party, multi-tenant Cloudinfrastructure & services:

* available on subscription basis

Hybrid/InterClouds

Mixed usage of private and public Clouds: Leasing publiccloud serviceswhen private cloud capacity is insufficient

Consumers will require different QoS to be maintained by their providers.

Providers will need to consider and meet different QoS parameter of each individual consumer

So market oriented resource management is necessary to regulate the supply and demand cloud resources at market equilibrium.

Market Oriented Cloud Architecture

Market Oriented Cloud Architecture

Support customer-driven service management. Define computational risk management tactics. Derive appropriate market-based resource

management strategies. Incorporate autonomic resource management

models. leverage VM technology to dynamically assign

resource shares according to service requirements.

Global Cloud Exchange

Bridge disparate CloudsAllows consumer to choose provider that

suits their requirementsHelp providers to perform effectivelyHelp Brokers to gain their utility through

difference in price.

Benefits

Unwillingness to shift from traditional controlled environment

Regulatory pressureHow to obtain restitution in case of SLA

violation

Challenges

Cloud Computing is new and promising paradigm. Paper discusses market oriented allocation of

resources within clouds and emerging cloud platforms.

Cloud technologies needs extended support: QoS between user and providers to establish SLA’s

Protocols needs to be extended to support interoperability between different cloud services.

Market oriented global Cloud exchange for trading services.

Address regulatory and legal issues.
