  2. Vision: Modular, Internet-scale resource and service pool • Virtualization, dis-aggregation • components of monolithic computer systems - such as storage, cycles, and UI – are virtualized as (web) services that can be accessed and invoked via private or public networks using Internet protocols • result: a vast pool of resources and services is available on public and private networks for completing user tasks (some free, some for fee) • Aggregation • when a task (application) needs to be completed, the necessary resources are obtained from the pool • discovered, selected – based on criteria such as proximity, performance, ownership, cost - and aggregated to meet the needs of the task at hand • Reuse • when the task is completed, resources are returned to the pool

  3. Scalability and Usage Examples • Personal (proximity) Area Network • user carries some of her hardware and data, e.g. IR personal server, augments its capabilities – such as storage and UI – from the environment • NB: assumes pervasive, rich embedded computer resources in the environment, initially hot spots “smart spaces” • Home Area Network • home PCs pool their collective cycles temporarily to compress edited home movie (e.g. into DVD-R format) • NB: users benefit from having more, higher-end PCs • intranet/Internet • a company pools its workstations, servers and (off hours) office PCs into a grid to perform crash testing • NB: motivated to procure high-end office PCs

  4. Customer View, Benefits • Ultimate Mobility • Seamless, untethered, access to computing resources embedded in the environment (cycles, storage, UI, connectivity) • Sharing of Resources • Better return on investment; resource pooling, aggregation, and load balancing; reliability; automation for business and consumer • Behavioral attributes • Adaptive to changes in the environment • bandwidth variation, intermittent connectivity and node availability • Responsive to user needs • content associated with user, not devices; power on demand

  5. (Enabling) Model Behind the Vision • Internet Distributed Computing • Dynamic, task-driven configuration of computing elements • A universe of globally connected and composable services, resources (e.g. cycles, storage), devices • Internet as a computing platform • Ability to discover and dynamically combine components into task-specific functional groupings • aggregate, augment device capability • capacity on demand, reusable: return to pool when task completed • Multiple scales: proximity-area to global grids

  6. Vision: Design Implications • Edge processing (rich clients, edge servers) • near target rather than all the way back to centralized servers (scale: supports more devices, connectivity: saves upstream bandwidth) • NB: Edge is essentially any device embedded in the network that can render the service, e.g. a PC; this is NOT ISP-server edge model • Ad-hoc networking (greater device “intelligence”, autonomy) • discovery, self-configuring: for scale and mobility • Data-centric model (user-centered, not device-centered data) • access same data from a variety of devices • Intermittent connectivity (local storage, caching) • devices move in and out of range, power down • caching, data and service proxies

  7. Fundamental Components/Principles • To realize the vision, scale from PAN to global grid, need: • virtualization of resources: cycles, storage, UI • resource discovery, dynamic configuration • ad-hoc networking, run-time binding, platform independence • aggregation and orchestration of resources • pooling, dispatching, synchronization • security, authentication • by ownership, proximity, organizational boundaries, intranet, Internet • DSL doing research and concept proofs of IDC fundamentals

  8. Industry Trends, Drivers • Demands for efficient use of computing resources • Utility computing • resource pooling and load balancing, dynamic allocation/provisioning of servers, storage • Autonomic computing • automated operation, self-management • Grid computing • share and amplify compute power, access to unique data • Real-world awareness, interaction • sensors, automation

  9. Requirements, Building Blocks for Future Environments • Pervasive/ubiquitous computing • scale++: Internet of things (devices, sensors, objects) • compute resources all around in the environment • initially islands of “smart spaces” • utility access gateways and servers – cache and stage data, conserve power on portable devices • users carry some of their compute/data, e.g. personal server, augment capabilities from the environment • Proactive computing • react to real-world stimuli, initiate actions based on user’s context (intent, activity, location)

  10. Assumptions and Design Implications • Connectivity – hybrid: wireless, wired (proxy) • wired connection (WAN), combined with short-range, high-bandwidth (Mbps+) wireless • aggregate bandwidth on edge >> backbone • Scale – number of devices • edge processing: process and filter near source vs. communication to remote, centralized servers • ad-hoc networking (mobility/wireless networks, too many devices to configure and keep up to date) • Users carry some of their compute/data, e.g. personal server, augment capabilities from the environment

  11. Backup

  12. Goal • Accelerate distributed computing on the Internet, increases end-user value (Biz and Consumer), Silicon use • Define and Extol IDC stack. • Enhanced Web Service Technology • Integrated Managed Run Time Environments • Provide a foundation for pervasive computing from a small-scale PAN to virtual, planetary grids.

  13. IDC Benefits for the World • Dynamic aggregation of resources for computing on demand. • Reusable SW and associated developer benefit. • Foundation for proactive and pervasive computing. • Reduce manageability cost and complexity. • More efficient use of computing resources. • Reliability, availability and scalability.
