Shared pool of configurable computing resourcesOn-demand network accessProvisioned by the Service Provider

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.cloud computing customers do not own the physical infrastructure.Cloud computing users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use.Low shared infrastructure and costs, low management overhead, and immediate access to a broad range of applications

Resource PoolingBroad Network AccessRapid ElasticityMeasured ServiceOn Demand Self-Service

ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays.ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events.Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures.On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each services provider. Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts).

Cloud Service Models6Software as a Service (SaaS)Platform as a Service (PaaS)Infrastructure as a Service (IaaS)

Google App Engine

SalesForce CRMLotusLive

IaaSdelivers computer infrastructure, typically a platform virtualization environment, as a service. Rather than purchasing servers, software, data center space or network equipment, clients instead buy those resources as a fully outsourced service. PaaSdeliver a computing platform where the developers can develop their own applications.SaaSis a model of software deployment where the software applications are provided to the customers as a service.

VirtualizationVirtual workspaces: An abstraction of an execution environment that can be made dynamically available to authorized clients by using well-defined protocols, Resource quota (e.g. CPU, memory share),Software configuration (e.g. O/S, provided services). Implement on Virtual Machines (VMs): Abstraction of a physical host machine,Hypervisor intercepts and emulates instructions from VMs, and allows management of VMs,VMWare, Xen, etc.Provide infrastructure API:Plug-ins to hardware/support structuresHardwareOSAppAppAppHypervisorOSOSVirtualized Stack

What is the purpose and benefits? infrastructure-less.pay as used and on demand, all of us can save in capital and operational investment!Clients can:Put their data on the platform instead of on their own desktop PCs and/or on their own servers.They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc. 11

Cloud-SourcingWhy is it becoming a Big Deal:Using high-scale/low-cost providers,Any time/place access via web browser,Rapid scalability; incremental cost and load sharing,Can forget need to focus on local IT.Concerns:Performance, reliability, and SLAs,Control of data, and service parameters,Application features and choices,Interaction between Cloud providers,No standard API mix of SOAP and REST!Privacy, security, compliance, trust12

Cloud StorageSeveral large Web companies are now exploiting the fact that they have data storage capacity that can be hired out to others. allows data stored remotely to be temporarily cached on desktop computers, mobile phones or other Internet-linked devices.

Amazons Elastic Compute Cloud (EC2) and Simple Storage Solution (S3) are well known examplesMechanical Turk13

Utility Computing EC2Amazon Elastic Compute Cloud (EC2):Elastic, marshal 1 to 100+ PCs via WS,Machine Specs,Fairly cheap!Powered by Xen a Virtual Machine:Different from Vmware and VPC as uses para-virtualization where the guest OS is modified to use special hyper-calls:Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-V).Supports Live Migration of a virtual machine between hosts.Linux, Windows, OpenSolarisManagement Console/AP

The FutureMany of the activities loosely grouped together under cloud computing have already been happening and centralised computing activity is not a new phenomenaGrid Computing was the last research-led centralised approachHowever there are concerns that the mainstream adoption of cloud computing could cause many problems for usersMany new open source systems appearing that you can install and run on your local clustershould be able to run a variety of applications on these systems
