Computer Utilities • 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 & Cloud Computing • 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.
Defining Cloud • "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....}

Market Oriented Cloud Architecture • 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 Clouds • 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.
Emerging Cloud Platforms • Amazon EC2 • Google App Engine • Microsoft Live Mesh • Sun Grid • Grid labs Aneka
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 • Reliability
Google App Engine • For developing and hosting web application in Google managed datacenter • Web based Administration Console. • 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 using internet. • Access through Web based Live Desktop or own device with Live Mesh software installed. • Password protected and authenticated via Windows Live Login. • File transfers are protected using SSL
Sun Grid • Now Know as oracle Grid • Solaris OS, Java, C, C++ and FORTRAN. • Open source batch queuing system. • Sun Grid Web Portal or API. • Used on computer farm or high performance computing cluster
Grid Labs Aneka • Based on .Net framework of Service Oriented Platform. • Supports multiple application models and communication protocols. • Create and start enterprise instance. • Provides SLA • Grid bus broker
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 • Market directory • Banking system • Brokers • Price setting mechanism • Admission control mechanism • Resource management system • Consumers utility function • Resource management proxy
Benefits • Bridge disparate Clouds • Allows consumer to choose provider that suits their requirements • Help providers to perform effectively • Help Brokers to gain their utility through difference in price.
Challenges • Unwillingness to shift from traditional controlled environment • Regulatory pressure • How to obtain restitution in case of SLA violation
Conclusion • 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.
