Agenda
3 IT Architecture
IT Services
• 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
Why Architecture?
4 IT Architecture
IT Services
• 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)

Data Architecture Principles• subset of EA principlesEnterprise Information Model• based on semantic model• business entitiesLogical Data Models• hierarchy of models• includes COTS• use data dictionaryPhysical Data Models• tables, rows, columns, keysData Management Policy• information life cycle• data quality – active

Focus on System Life Cycle
12 IT Architecture
• 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)

Process
13 IT 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 thereafterArchitecture 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
Architecture Board
Solution ArchitectureWork-off list
IT Services
• 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

Non-Functional Requirements
15 IT Architecture
Quality Perspective Definition Measurement
Performance System response time for defined functions or use-cases.
L = latency – response timeJ = jitter - % variation in LH = headroom - % available spare capacity.
ScalabilityAbility of a system to handle increasing or decreasing volumes within allocated resource limits (headroom).
SF = scalability factor in the range 0..1SL = scalability limit (point of diminishing returns)
Availability Ability of a system to function when required in spite of errors and failures.
% of target availabilitye.g. 99.98% of 24 x 7
Operability How well a system operates within the IT landscape. High – Medium – Low
Usability Ease of use, or conviviality of a system. High – Medium – Low
Security Ability to prevent unauthorised access to information. High – Medium – Low
Regulation Conformity with laws and regulations. High – Medium – Low
Flexibility Ease of change of a given system. High – Medium – Low
FeasibilityAbility of the organisation to deliver the system subject to constraints of available expertise, technology, time and resources.
High – Medium – Low
IT Services
• 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
Architecture Board
16 IT Architecture
IT Services
• 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
