  • This has to be much more widely distributed. As Cloud becomes more prevalent, there will be a much greater battle between the systems engineers and software engineers as greater attention to modeling and architectural modeling for each comes to the forefront, causing the lines between the two begin to blur. This will be most on display as mid to senior level technologists fight over the use of public vs. private clouds, with Hybrid Clouds being the likely long-term winner. Clouds typically mean Virtualization and SOA, and Architects are fighting to get their heads around these two technologies. When ArchiMate & TOGAF are applied to methodologies like IBM's CCRA and SOMF [each already borrows from TOGAF in their present form, but I mean specific to each individual project] and you bring in CBDI's SoaML mapping, you can actually come up with an entire enterprise model framework that makes sense and allows your application and infrastructure/technology architects [respectively] create models and artifacts that map to the enterprise architecture model AND the business need.

Type of Architecture? <ul><li>TOGAF (Types of Architecture) </li></ul><ul><ul><li>Business (or Business Process) Architecture – business strategy, governance, organization and key business processes </li></ul></ul><ul><ul><li>Data Architecture – logical and physical data assets </li></ul></ul><ul><ul><li>Applications Architecture – blueprint for individual application systems to be deployed </li></ul></ul><ul><ul><li>Technology Architecture – logical software and hardware capabilities required to support deployment </li></ul></ul><ul><li>SAE (View) </li></ul><ul><ul><li>Business - business needs and how the business operates in terms of goals and objectives, organizational structure, processes, information </li></ul></ul><ul><ul><li>Specification - software services from a platform independent perspective. Logical services and their interrelationships </li></ul></ul><ul><ul><li>Implementation - services packaged into automation units, dependencies between the automation units, implementation constraints that will govern the internal design and deployment of these units. </li></ul></ul><ul><ul><li>Deployment - deployment choices for run time services. Implementation view services mapped to deployment units and defined optimum configuration on the computing infrastructure. </li></ul></ul><ul><ul><li>Technology - technologies to enable the service lifecycle at all levels – from planning through specification, design and execution to retirement. </li></ul></ul>Information Systems Architecture Comment: A key aspect of SOA is the clear separation of logical services from implementation or the application architecture by contract based interface. TOGAF 8.1.1 does not define “service” as a first order concept, and it would be expected that this will change in TOGAF 9
