  • Process
  • Governance
  • Funnel
  • Questions

IT Architecture

why architecture
Why Architecture?
  • Enterprise Architecture – a holistic approach to IT
    • Principles to drive realisation of IT Strategy
    • Rational approach to prioritising technology investment
  • Seeks benefits across the University as a whole
    • Simplify – reduce complexity (and associated costs)
    • Standardise – define and comply with standards, achieve economies of scale
    • Rationalise – eliminate duplication, maximise reuse
  • Architecture Governance
    • ITIL compatible – dovetails into existing IT Governance
    • Validates compliance so that benefits are actually achieved

IT Architecture

what is architecture
What is Architecture?
  • Policies
    • Security – IAM, encryption
    • Green IT – carbon counting, efficient use of resources
    • Services – loosely coupled components that implement services
  • Standards
    • SIB – a published Standards Information Base
  • Procedures
    • Architecture Process – covers entire system life cycle, includes:
    • Architecture Governance – extension of IT governance
  • Guidelines
    • Principles – based on IT Strategy + industry best practice
    • Patterns – reusable designs (benefit from experience)
    • TAM – Target Architecture Model (what we are aiming for)

IT Architecture

architecture framework
Architecture Framework

IT Architecture

data architecture
Data Architecture
  • Data Architecture Principles
  • subset of EA principles
  • Enterprise Information Model
  • based on semantic model
  • business entities
  • Logical Data Models
  • hierarchy of models
  • includes COTS
  • use data dictionary
  • Physical Data Models
  • tables, rows, columns, keys
  • Data Management Policy
  • information life cycle
  • data quality – active management

IT Architecture

focus on system life cycle
Focus on System Life Cycle
  • System Life Cycle Process extends over entire life cycle of a system
  • Architecture Process supports entire system life cycle
  • Support model
  • Retirement (or Exit if system is externally managed service)

IT Architecture

process
Process

Architecture Board

Work-off list

Solution Architecture

  • Solution Architecture
  • summarise architecture decisions and known facts
  • high-level business, application, data and technology description
  • produced by architects + project team
  • defines what will be delivered - changes subject to change control
  • delivered with PID, or shortly thereafter
  • Architecture Board
  • held before go-live (more if necessary)
  • assures solution is fit for purpose and Solution Architecture has been delivered
  • may result in work-off list, or delay go-live

IT Architecture

solution architecture description
Solution Architecture Description
  • A short document that summarises the proposed solution
    • Not a design document (does not cross boundary between architecture and design)
    • Delivered with, or shortly after, PID
  • Contents:
    • Background + high-level architecture overview
    • Architecture Principles – how the solution will address them
    • Assumptions – major assumptions only
    • Decisions – technology choices etc.
    • Technology Stack – hardware, software, versions
    • Protocol Stack – which protocols used and where
    • Environments – (e.g. Development, Test, Production) with 1st cut sizing
    • Key Non-functional Requirements – how they will be met
    • Data – use/creation of enterprise data

IT Architecture

architecture board
Architecture Board
  • Technical meeting chaired by IT Architect
  • Reviews solution architecture for:
    • Overall fitness for purpose
    • Adherence to Architecture Principles, Standards
    • Security – conformity with security policy, addresses specific risks
    • Information – access to / impact on the university’s enterprise data
    • Architecture Concerns – technical risks, issues etc.
  • Approves solution
    • May request / impose remedial action as necessary
    • Delay project close-down if outstanding major issues
    • Delay go-live if major risks to the university

IT Architecture

changes
Changes
  • Architecture Compliance Form
    • Summary of system architecture
    • Check list – Principles, Requirements, Standards, Technology, Environments
  • Operational Testing – new focus
    • To show compliance with non-functional requirements
  • Architecture Compliance Review
    • Held before go-live
    • Based on Compliance Form
  • Architecture Authority process
    • Oversees architecture governance
