• Introduction• Market Oriented Cloud Architecture • Emerging Cloud Platforms• Global Cloud Exchange and Markets• Summary

Introduction

“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.”

Leonard Kleinrock

Introduction

• New Computing Paradigms – Cluster Computing– Grid Computing– P2P Computing– Service Computing– Cloud Computing

Cloud

"A Cloud is a type of parallel and distributedsystem consisting of a collection of interconnectedand 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.”

Market Oriented Cloud Architecture

• Need – 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

• Users/Brokers :– Submit service request from any where in the

world. • SLA Resource Allocator :– Interface between cloud provider and users.

SLA Resource Allocator

Emerging Cloud Platforms

Amazon EC2

• Elastic Compute Cloud (EC2)• Amazon Machine Image (AMI)• EC2 Uses XEN Virtual Machine• Virtual Os :Linux, Solaris, Windows• Simple Storage Service• Elastic IP address • Amazon Cloud Watch• Realiability

Google App Engine

• For developing and hosting web application in google managed datacenter

• Automatic scaling*• Free up to certain level of consumption• Support for python, java, and Go• Restrictions

Microsoft Live Mesh

• Access stuffs on your computer from almost anywhere

• Free to use internet based file synchronization application

• Remote desktop access via internet

Sun Grid

• Now Know as oracle Grid• Open source batch queuing system• Used on computer farm or high performance

computing cluster

Global Cloud Exchange and Markets

Limitations of present service providers

• Inflexible pricing• Consumers are restricted to offering from a

single provider at a time• Unable to swap one provider for another• No standard interface

Global Cloud Exchange

Global Cloud Exchange

• Market directory• Banking system• Brokers• Price setting mechanism • Admission control mechanism• Resource management system• Consumers utility function• Resource management proxy

Challenges

• Unwillingness to shift from traditional controlled environment

• Regulatory pressure• How to obtain restitution in case of SLA

violation
