1 Reference Architecture in Sweden

2 Reference architecture What is a reference architecture? A blueprint for an architecture that can be implemented in different ways (as long as you stay within the frames of the architecture). Guidelines A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. It also provides a common vocabulary with which to discuss implementations. [wikipedia]

3 Purpose of reference architecture Reference architecture = Building norm Rule set for development of integrations X Integration platform Reference architecture for integration describes the architecture in the grey box (as we want it to be).

4 Organizational needs 1. Kraven på att snabbt och säkert dela information mellan landsting och invånare ökar kontinuerligt, mycket på pga. den nationella IT- strategin (e-hälsa). Stora krav på realtidskommunikation online, synkron, stora krav på prestanda och stora krav på tillgänglighet samt krav på färskhet av data. T.ex. elektroniska sjukintyg, e-recept, mina vårdkontakter, nationell patientöversikt 2. Behoven på integration ökar även inom vår egen verksamhet (ÖLL, PDL, Socialstyrelsen etc) då landstinget använder IT i större uträckning ställer stora krav på att dela information mellan system.. T.ex. Labbsvar, kvalitetsregister, recept, medicinsk tekniska produkter (Dicom)

16 Services and contracts

17 What does a service contract consist of? Service contract description (eg. Service domain description) Template and instructions in RIV-method (Cehis web page) Documentation of all contracts Name, in and out messages Processing rules that need to be followed Technical definition per contract Instructions in RIV Technical Guidelines WSDL-file (metadata for envelope, communication protocol and security) XML Schemas (metadata for request and response messages) Exemple messages

18 Service interactions Service interactions are created from contracts Three types: Request-Response Response (most common) Synchronous service whole task is performed while waiting Spread information Asynchronous service Information is received, but is handled later Task Result Two way interaction Consumer gives producer a task (asynchrounously) Producer gives result by becoming consumer and consumer becomes producer (of result service) -> I.e. two service contracts that cooperate

19 What are RIV technical guidelines? Transport Today focused on SOAP-based web services over https: -Interop -Security Guideline -profile RIV Tekniska 2.0 Anvisningar - RIV Tekniska Basic Profile Anvisningar - Profil - Profil Message Envelope Header Technical aspects on content: -Interop -Versioning Guideline Service schema 2.0 Body

21 Maintenance and support Maintained by Cehis Maintenance conducted openly at EU:s project place for open source All work results are Public Domain Different types of support Help forum Service contract generator on the web

22 Versioning Forward-backward-compatibilitycompatibility - mechanisms Namespace controls main version Schema name (file) and version attribute controls minor version Extension element (any-element) last in every sequence Forward/backward compatible change New, non-mandatory element in a structure Non-compatible change Mandatory elements needed Schema is unchanged but sematics different I.e. other rules for what consumers / producers must do

24 Integration methodology National architecture ÖLL BP Business plan National BP Business plan ÖLL IT-strategi ÖLL needs Direct/ Indirect requirements Business Strategy for integration Principles, goals, maturement step Reference architecture SAD Goals Logical(information) & Technical view: Patterns, Platform, Architecture principles Use cases Concrete & clear goals Clarify ref. arch. Organization ICC Roles Competence, Support processes and Routines Security/IT- infrastructure Non functional req. Topology, DMZ Detailed req. spec. Clear req., generic ESB Current situation Operation, etc Gap analysis: Current situation vs. needs, Strategy, Architecture, Requirements Product choice Other critera for evaluation Competence, product strategy, simplicity, other regions, cost etc Action plan Introduction of new product, update organization, introduction plan, budget

25 Integration strategy No standard exists today Differs per company, authority, county council But there is a red thread Focus on product strategy e.g. Biztalk Focus on architecture e.g.. ESB, service orienterad, patterns Focus on technology e.g. security Focus on business Focus on rules, integration principles Focus on action plan, roadmap, maturement step Focus on strategic decisions Focus on work methodology, processes Focus on economy model Focus on business needs

26 Purpose for an integration strategy 1. Management: Long term plan for handling integration control on costs and delivery regarding integration 2. Maintenance/architecture/development: Mainly a guidance document for developers and architects = forces the management to make decisions on principles and policies. Necessary to be able to succeed with introducing an integration platform or to introduce an organization for integration.

32 Main pattern SOA ( online services ) SOA = Service-oriented architecture

33 Main pattern EDA ( subscription services ) EDA = Event-driven architecture

34 ESB Support for technical integration patterns. Routing Enterprise Service Bus Transformat ion Integration logic Aggregator Enrichment Support for synchronous and asynchronous connections of building blocks to integration flows that implement integration services. Here prerequisites are created for BAM and statistics for SOA Governance. Technical connection WS SFTP ODBC HTTPS Adapters Clinical portal Care system Data warehouse Support service Service consumers and producers that are connected through the ESB s technical adapters

35 Integration platform as receipient of integration components of the five different types Every integration service becomes an integration component in the platform. The blueprint controls how the architecture becomes in the platform (what components are developed and how the interact)
