2 Abstract Endrings- og konskvensanalyse i moderne arkitekturelle rammeverk [Impact and Consequence Analysis in Modern Architectural Frameworks] Vi skal se på hvordan nyere arkitekturelle prinsipper kan hjelpe analysere konsekvenser av design/arkitekturer, samt konskevenser av endringer på eksiterende design/arkitektur. Mer spesifikt, skal vi se på det som er med på å gjøre slike konsekvensanalysene letter i disipliner som forretningsarkitektur(business Architecture, BA), forretningsprosesstyring (Business Process Manager, BPM), og tjenesteorientert arkitekur ( Oriented Architecture, SOA). [We will be looking at how newer architectural principles may help analyze consequences of a design/architecture, as well as the potential impact of changes on existing design/architecture. Specifically, we will be looking at the enablers inherent in Business Architecture (BA), Business Process Management (BPM) and Oriented Architecture (SOA).]

3 Keywords - Impact & Consequence Analysis or CHANGE as a non-functional (f. ex. System Quality) requirement Planning for CHANGE, managing CHANGE Impact management (part of change management) Example: down-time minimization, non-invasive and/or nondisruptive change implementation... Impact analysis (also simulation, estimation) Change control Change anticipation, prediction, risk planning (part of risk management) Requirements/prerequisites for change planning & management: Where is the information we need for predicting/estimating & managing change?

4 Road Blocks What does NOT help us realize predictability, impact analysis, change management, system quality assurance/control etc? COMPLEXITY... Difficult-to-master technologies Sheer size, large number of (un-documented) relationships Systems implemented using technologies (with their implied architectures) that do not expose their logic (or their lack of logic), their assets and relationships between their assets Hard-wired systems (i.e., systems that do not lend themselves to change & interoperability easily) Lack of standardization

21 The Cloud: One of many definitions Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models. Benefits? On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Measured Cloud from a s Point-of-View? IaaS, PaaS, SaaS Cloud Deployment Types?
