Managing Diverse IT Infrastructures

Outsourcing the IT Function


Building an it infrastructure
Building an IT Infrastructure

  • Every organization developed its own communication infrastructure

  • Technologies did not interoperate well

  • Reliance on proprietary organizations meant that companies were locked in to a specific vendor technologies

Performance and reliability problems


Internet technologies and open standards
Internet Technologies and Open Standards

  • Organizations can share a communication infrastructure common to all business partners and customers

  • Communication technologies incorporate well due to TCP/IP standards

  • Organizations are less locked in to specific vendor technologies

Combine technologies from numerous vendors and expect them to interconnect seamlessly


Incremental service providers and common infrastructures
Incremental Service Providers and Common Infrastructures

  • As communication technologies improve and become more compatible and modular, businesses can obtain smaller increments of service from outside vendors with shorter lead times and contract durations

    • Pay for what you need

  • Service partners and new business models

    • Outsource services that are needed

    • Leads to diverse IT infrastructures

    • Managing service provider relationships becomes important

      • Virtual integration


New service models and benefits opportunities
New Service Models and BenefitsOpportunities

  • Overcome the shortage of specialized skills by reducing the need for internal staff

  • Network-based service delivery models help businesses quickly develop new capabilities

  • Service providers can quickly achieve economies of scale in IT investments to maintain highly available and reliable systems

  • Improves cash-flow by reducing the initial (costly) IT investments

  • Upgrades performed centrally and timely

  • Services available anywhere, anytime over the Net

On Demand, Utility and Grid Computing Models

Common attributes

  • Financial models that make IT services easier and less risky to procure and manage

  • Restructuring and reengineering of existing application s to make them easier to manage and use

  • Enhancements to infrastructure to improve interoperability and efficiency in use of computing assets



Grid computing
Grid Computing

  • “A computational grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities.” Foster and Kesselman, 1998


Grid checklist characteristics of a grid foster 2002
Grid Checklist: Characteristics of a GridFoster, 2002

  • Coordinates resources that are not subject to centralized control

    • Integrates and coordinates resources and users that live within different control domains

  • Standard, open, general-purpose protocols and interfaces used

    • Built from multi-purpose protocols and interfaces that address fundamental issues (i.e., authentication, authorization, resource discovery, resource access)

  • Deliver non-trivial qualities of service

    • Allow constituent resources to be used in a coordinated fashion to deliver various qualities of service to meet complex user demands

Grid computing1
Grid Computing

  • Application layer includes all different user applications (science, engineering, business, financial), portals and development toolkits supporting the applications. This is the layer that users of the grid will "see".

Grid computing2
Grid Computing

  • Middleware layer provides the tools that enable the various elements (servers, storage, networks, etc.) to participate in a unified Grid environment. The middleware layer can be thought of as the intelligence that brings the various elements together - the "brain" of the Grid!

Source: gridcafe.web.cern.ch/gridcafe/


Grid computing3
Grid Computing

  • Resource layer, made up of the actual resources that are part of the Grid, such as computers, storage systems, and electronic data catalogues which can be connected directly to the network

  • Network assures the connectivity for the resources in the Grid

Source: gridcafe.web.cern.ch/gridcafe/

Grid Computing, Another View

  • User Applications

    • Obtain the necessary authentication credentials to open the files (resource and connectivity protocols)

    • Query an information system and replica catalogue to determine where copies of the files in question can currently be found on the Grid, as well as where computational resources to do the data analysis are most conveniently located (collective services)

    • Submit requests to the fabric - the appropriate computers, storage systems, and networks - to extract the data, initiate computations, and provide the results (resource and connectivity protocols)

    • Monitor the progress of the various computations and data transfers, notifying the user when the analysis is complete, and detecting and responding to failure conditions (collective services).

Grid computing another view1
Grid Computing, Another View

  • Collective Services

    • Keep directories of available resources updated at all times

    • Broker resources (which like stock broking, is about negotiating between those who want to "buy" resources and those who want to "sell")

    • Monitor and diagnose problems on the Grid

    • Replicate key data so that multiple copies are available at different locations for ease of use

    • Provide membership/policy services for keeping track on the Grid of who is allowed to do what, when.

Grid Computing, Another View

  • Resource and connectivity protocols handle all "Grid specific" network transactions between different computers and other resources on the Grid

  • Fabric - all the physical infrastructure of the Grid, including computers and the communication network

Types of grids source grid cafe
Types of GridsSource: Grid Cafe

  • National Grids - couple high-end resources across a nation

  • Private Grids - characterized by a relatively small scale, central management and common purpose

  • Project Grids - created to meet the needs of a variety of multi-institutional research groups and multi-company "virtual teams", to pursue short- or medium-term projects (scientific collaborations, engineering projects)

  • Goodwill Grids - for anyone owning a computer at home who wants to donate some computer capacity to a good cause


Types of grids source grid cafe1
Types of GridsSource: Grid Cafe

  • Peer-to-peer - depends on people sharing data (like the now defunct Napster and its many subsequent imitators) between their computers

    • No central control

  • Consumer Grid - resources are shared on a commercial basis, rather than on the basis of goodwill or mutual self-interest

    • Companies or other organizations rent distributed resources, and the owners of these resources are paid for the computing power or data storage capacity they contribute, by a "middleman" in charge of the middleware


Managing risk through outsourcing internal vs external service delivery
Managing Risk Through OutsourcingInternal vs. External Service Delivery

  • If unique and provide a significant advantage, don’t outsource

  • IT services essential for running a business but common across competitors can be outsourced

Keep internal

Is external deliveryreliable and lower cost?

Does service offer a competitive advantage?

Outsource

Keep internal


Incremental outsourcing and managing risks
Incremental Outsourcing andManaging Risks

  • Outsourcing a particular function rather than the entire operation

  • Consequences of mismanagement are not as far-reaching

  • Offers new and attractive choices to managers seeking to improve the IT infrastructure
