1 IT Services IT Architecture at Birmingham RUGIT March 2012

2 IT Services Architecture at Birmingham Architecture at Imperial Anti-Architecture at Warwick Group discussion Agenda 2 IT Architecture

3 IT Services Why Architecture? What is Architecture? Enterprise Architecture Framework Principles Process Governance Funnel Questions Agenda 3 IT Architecture

4 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

5 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) What is Architecture? 5 IT Architecture

11 IT Services Architecture Principles 11 IT Architecture

12 IT Services 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)

13 IT Services Start-upInitiationImplementationClose- down Post Project Actions PoC / Investigation Iterations Change control Artefacts Change requests Outcomes Project Approval ClosureConfirmation of benefits 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 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 Architecture Board Solution Architecture Work-off list

14 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 1 st cut sizing Key Non-functional Requirements – how they will be met Data – use/creation of enterprise data Solution Architecture Description 14 IT Architecture

15 IT Services Non-Functional Requirements 15 IT Architecture Quality Perspective DefinitionMeasurement Performance System response time for defined functions or use-cases. L = latency – response time J = jitter - % variation in L H = headroom - % available spare capacity. Scalability Ability of a system to handle increasing or decreasing volumes within allocated resource limits (headroom). SF = scalability factor in the range 0..1 SL = scalability limit (point of diminishing returns) Availability Ability of a system to function when required in spite of errors and failures. % of target availability e.g % 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 Feasibility Ability of the organisation to deliver the system subject to constraints of available expertise, technology, time and resources. High – Medium – Low

16 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

17 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 Changes 17 IT Architecture
