What is a GridResource sharingComputers, storage, sensors, networks, Sharing always conditional: issues of trust, policy, negotiation, payment, Coordinated problem solvingBeyond client-server: distributed data analysis, computation, collaboration, Dynamic, multi-institutional virtual orgsCommunity overlays on classic org structuresLarge or small, static or dynamic

Grid Computing 2.0?Grid ComputingCloudCloudCloudComputing

Cloud ComputingWIKIPEDIA: Cloud computing is a new (circa late 2007) label for the subset of grid computing that includes utility computing and other approaches to the use of shared computing resources. Cloud computing is an alternative to having local servers or personal devices handling users' applications.

News Blog: Cloud computing, the notion of outsourcing hardware and software to Internet service providers, is showing the classic signs of disruptive technology--it's not good enough for the masses yet, but it has clear potential to shake things up.

Forrester: Cloud computing is a new IT outsourcing modelcloud computing is looking like a classic disruptive technology.

The Architecture of Cloud Computing

Upon Cloud ComputingCloud storage: it is a model of networked data storage where data is stored on multiple virtual serversHosted by third parties, Hosting companies operate large data centersCloud services: Web services offered via cloud computing.

Cloud Computing, Grid Computing and Web2.0Cloud computing as being a complement to grid computing, focusing more on scalable, on-demand, Web 2.0-type applications

The architecture of Cloud Computing certainly could handle a lot of the batch workloads traditionally associated with grid computing.

Examples of Cloud Computing WorkloadsWeb 2.0 applications Provide rich user experience including real-time global collaboration Enable rapid software development Software to scan voluminous Wikipedia edits to identify spam Organize global news articles by geographic location Data-intensive workloads based on scalable architectures, such as Googles MapReduce framework Financial modeling, real-time speech translation, Web search Next generation rich media, such as virtual worlds, streaming videos, Web conferencing, etc. New services can be created and published via a completely integrated Eclipse-based environment

Amazon EC2 IsA Web service that provides resizable compute capacity in the cloud.

Designed to make Web-scale computing easier for developers.

A simple Web service interface that provides complete control of your computing resources

Amazon EC2 Benefits You Because It:Reduces the time required to obtain and boot new server instances to minutes

Quickly scales capacity, both up and down, as your computing requirements change

Changes the economics of computing:Pay only for capacity that you actually use

MicrosoftWebStudio WebStudio is an infrastructure to provide large-scale Web data management and processing capabilities. It provides an integrated development environment (IDE) for use in quickly prototyping and conducting experiments at Web-scale.

Disruptive TechnologyEnterprise to Personal

Disruptive TechnologyEnterprise to PersonalDesktop to WebUsers may no longer have to be tethered to a traditional computer to use an application.Any device that can access the Internet will be able to run a cloud-based application Will not worry about storage capacity, compatibility or other concerns Without having the bother of upgrading the application version

Challenge & VentureSecurityFor single user: Is the storage reliable?For all user: If terrorists attack several Computing CloudsPrivacyIf internet breaks down one day?

RozmicIntetnetThe architecture behind cloud computing is a massive network of "cloud servers" interconnected as if in a grid running in parallel, sometimes using the technique of virtualization to maximize computing power per server.A front-end interface allows a user to select a service from a catalog. This request gets passed to the system management which finds the correct resources, and then calls the provisioning services which carves out resources in the cloud. The provisioning service may deploy the requested stack or web application as well.User interaction interface: This is how users of the cloud interface with the cloud to request services. Services catalog: This is the list of services that a user can request. System management: This is the piece which manages the computer resources available. Provisioning tool: This tool carves out the systems from the cloud to deliver on the requested service. It may also deploy the required images. Monitoring and metering: This optional piece tracks the usage of the cloud so the resources used can be attributed to a certain user. Servers: The servers are managed by the system management tool. They can be either virtual or real.

In late 2007 information technology giants Google and IBM announced a joint venture aimed at addressing the emerging paradigm of large-scale distributed computing, also known cloud computing One of the biggest advantages is that a user may no longer have to be tethered to a traditional computer to use an application, or have to buy a version thats specifically configured for a phone, PDA [personal digital assistant] or other device. Its likely that at some point any device that can access the Internet will be able to run a cloud-based application.Application services are available, independent of the user devices and network interfaces.
