Governance & Control, Challenges & Approaches for SOA using testable architectures Published paper on use of testable architectures and modelling to address in design time and run time challenges in services oriented architectures 
Build SAVARA from Source Building Savara SAVARA is built using Maven. Specifically version 3 of maven is required, as the build uses the Tycho maven plugins to create the Eclipse features/plugins and update site. 1. Check out... 
TAM BA Define Participants The participants in this example are Buyer, Store and Credit Agency. The business analyst will work with the business user to understand the different parties that will be involved in the business process. Depe... TAM BA Outline Scenarios Define a set of scenarios to represent each path through the business process, spanning the relevant participants that may be involved. At this stage, each interaction may be specified just as a line between th... TAM BA Message Examples Examples of the message content that will be associated with each interaction should be defined and linked to the relevant scenario interactions. Where existing schema is being used, then the messages should be... TAM Arch Information Model Where message types do not have an existing schema (or information model), or where the message content extends existing schema, the architect may want to begin the creation of new schema definitions created using the... TAM Arch Choreography Model The Choreography Model provides a global perspective over the interactions that can occur between a collection of participants in an architecture in order to achieve a common goal. It captures the interactions in whic... TAM Arch Deployment Model <Need to define what is required by an outline deployment model, and how it relates to the other models in this architectural phase> Details Repo: Create outline deployment model and stored in repo... TAM SA Locate Existing Services Before creating a new service, try to determine if an existing service meets the requirements. This task is best supported by a Service Repository. Examine information in the Service Repository to determine if t... TAM SD Service Model Create or refine the model of the service in Project SAVARA modeling tool and or Service Repository. Provide meta-data to define the high level properties of the service, and the link(s) to relevant artifacts that can... TAM SD Design Service Contract and Message Schema In his book SOA Design Principles [Erl 2008] Erl promotes the principal of Standardized Service Contracts. “Services within the same service inventory are in compliance with the same contract design standards. .... TAM SD Design Service Logic At this stage it is appropriate to define the internal logic for the candidate services. The way in which this is achieved may be specific to the nature of the service, and the runtime technology selected to implement... TAM Service Development The choice of implementation technology (and language) will be varied, and the methodology should not restrict the choice in anyway. However, the choice may determine how sophisticated the validation may be bet... TAM TS Service Unit Testing The primary source of test cases for a service will be the scenarios defined in the requirements gathering (and potentially SOA Analysis) phase. These scenarios provide the interaction ordering, and example message co... TAM TS Integration Testing Although individual services can be tested against the scenarios, to ensure they individually meet the business and service analysis requirements, the final test of a system will be full integration testing, to ensure... TAM Service Deployment <GPB: Not sure deployment is relevant to the methodology? As opposed to part the tooling?> Details Deployment packages (e.g. archives) and source artifacts can be stored in the SOA repository with ... TAM MS Continuous Conformance Checking The production environment can be monitored against the choreography models, to ensure that the interactions between the various system components (i.e. services) conform to the original business requirements. ... TAM Service Monitoring TODO: Monitoring of policies in the choreography and service contracts/designs needs to be discussed. The steps in this phase are: Continuous Conformance Checking Business Activity Monitoring
