Architectures and Simulation: Why Fault Tolerance is not at a Maximum Level?

Abstract: This paper is focused on difficulties in information technology (IT). Information technology has an important and stable place in the lives of people. A number of applications are installed on computers, mobile devices or tablets every day. There are verified methods and methodologies concerning optimal implementation. Although an appropriate interest is focused on architecture, major controversy still exists. Numerous surveys relate of problem with budgets, time, aims and quality. Even IT users prefer using MS Excel over complicated software. The high level of diversity and variety of relations are frequent issues. The software reflects the actual conditions recorded at a given moment into applications, although the real environment changes over time. The well-known object and multidimensional approach from the designing of information systems supports an active solution to this reality. Good experiences are achieved based on simulation with link to these approaches and intelligences as artificial, business, competitive, customer, swarm, and computational. This combination of objects, multidimensions, intelligences and simulations brings a higher level of fault tolerance in relation to mistakes and errors in the IT field. Simulation helps understand new conditions and changes. In simulation, all objects may be modified, new objects may be added, or certain objects may be dropped by preferences. The IT designers learn more about behavior in changed conditions, and unexpected relations are found.
