The Grid Computing Now! Knowledge Transfer
Network

• Grid Computing Now! KTN is aimed at championing
  Grid Computing to UK plc. See www.gridcomputingnow
  .org
• Project launched, February 2005. Now funded by
  the Technology Strategy Board, sponsored by DIUS.
• Collaboration with the National eScience Centre,
  Edinburgh, leading IT suppliers and CNR Ltd.
• Web platform industry news events webinars
  user case studies active engagement and regional
  programme.
• Loose definition of Grid Computing Technologies
  mainly focused on Virtualisation and Service
  Orientation.

  iceberg. Were moving to a future state where
  everything will be delivered to you as a
  service."

Sustainability and IT

• Not our problem, right?
• Average utilisation of equipment in the Data
  Centre is 10-15
• Worse with redundancy
• Powering processors consumes about 6-10 of the
  Data Centre budget.
• The rest goes on UPS Lighting Cooling ACDCAC
  
• Total carbon emissions is estimated at around
  2-3 and rising
• And energy costs will continue to rise too!

Modern Processor Architectures
EC Code of Conduct for Data Centres

• Increased efficiency through-
• Multiple cores
• Greater processing capacity
• Lower clock speed
• Lower power consumption
• Less heat generated
• Less cooling required
• Variable power utilisation
• Reduced idle power
• Remote LAN switching
• The battle is joined

Standard Building Blocks

• Cloud is a business model Grid is an access
  model
• Both are implemented using similar (or even the
  same) technology components, which can be thought
  of as building blocks
• These building blocks are used to build Clouds or
  Grids depends on what you need
• So if a standard exists for a particular Grid
  building block, it might be applicable to
  building Clouds

Is Cloud Disruptive?

• Definitely! But not a technology disruption. Its
  a disruptive business model.
• Cloud is characterized by services made available
  on-demand, and payment for these services based
  on actual usage.
• Some say Grids evolve to Clouds, others say
  Clouds are completely different from Grids
• Either way we have learned a lot about
  distributed computing thus far and this should
  help

20
Are We Done?

• While the referenced set of specifications
  provide some significant building blocks, others
  still need definition
• Term languages for describing Cloud resources and
  QoS constraints
• Extend Basic Execution Services state model to
  accurately describe VM instance lifecycle
• New information attributes for describing Cloud
  services and applications
• And the list goes on.

What is ..?

IT as a Service!
Todays world
Service Oriented Enterprise


Business scenarios definedwithin applications
Event Driven Business Scenario
Assembly of Services
Services
Applications

• Extraction of business scenarios and processes
  from application landscape
• Clear focus on defined services, which are
  reusable through an assebly of services
• Internal and external users get better access to
  data in different systems

• Processes and business scenarios hard-wired
  within applications
• Hard to make business connections necessary to
  change and improve processes
• ITs speed of change is limiting factor on
  business speed of change

25
Open Standards are available

• Key Standards for SOA
• Web Services Definition Language (WSDL)
• Simple Object Access Protocol (SOAP)
• Business Process Execution Language (BEPL)
• Universal Description Discovery Integration
  (UDDI)
• Web Service Choreography Interface (WSCI)
• Blocks Extensible Exchange Protocol (BEEP)
• Web Services Addressing (WS-Addressing)
• Security Assertion Markup Language (SAML)
• Web Services Distributed Management (WSDM)
• Web Services Trust Language (WS-Trust)

• Open Standards a reality, developing faster,
  supported of by technology industry and users
• Open Source a mainstream method for sharing
  common software and software licence reform
• Open Convergence of technology vendors and users
  to design new types of interactive process flows

Future of Applications

• Growth of Software as a Service
• on-demand access
• no time/need to buy and install
• Information as a service
• In-sourcing industry and environmental data
• Ad-hoc assembly of services and owned
  applications to meet business needs
• End user programming
• Eg.iGoogle,BPEL applications

Implications for IT Organisations

• Widespread diversity and integration of services
• A moving feast of service providers
• Dynamic reconfiguration of infrastructure
• License/Asset Management
• Virtual server sprawl
• Reliance on automated tools
• New types of users web hackers social
  networkers
• New types of problems mash-ups service rogues
  service storms
• Resolving faults in distributed environments
• IT will be the last to find out

32
Summary

• Cloud-based/Utility computing is coming of age
• It lies at the heart of the most innovative web
  services delivered today
• It provides cheap and easy access to
  infrastructure
• It provides a platform which is ideal for service
  delivery
• Software distribution and use models are changing
• Legacy hardware and applications present some
  obstacles
• Energy concerns represent a threat and an
  opportunity
• The IT function is poised for radical change!

Bill Gates, Microsoft, at TechEd, June 3rd 2008

• We're taking everything we do at the server
  level, and saying that we will have a service
  that mirrors that exactly. The simplest one of
  those is to say, okay, I can run Exchange on
  premise, or I can connect up to it as a service.
  But even at the BizTalk level, we'll have BizTalk
  Services. For SQL, we'll have SQL Server Data
  Services, and so you can connect up, build the
  database. It will be hosted in our cloud with the
  big, big data center, and geo-distributed
  automatically. This is kind of fascinating
  because it's getting us to think about data
  centers at a scale that never existed before.
  Literally today we have, in our data center, many
  hundreds of thousands of servers, and in the
  future we'll have many millions of those servers.
