7. VisualisationTo visualise the collected architectural information about the IT systems, the following three types of viewpoints have been identified:
• A global overview of the services and application components (land-scape viewpoint).
• Insight into the support of processes (process support viewpoint).
• Insight into the relations between applications, services, logic, and data(coherence and dependency viewpoint)

8.Concepts and their visual representation

9.Tool Design

Infrastructure UsageThe next step is to take a closer look at the infrastructure support for the application architecture. We first illustrate the modelling approach for the ‘Medium-independent processing’. A layer of infrastructure services supports the various application functions. We distinguish three types of infrastructural services:
• Data storage and access services; • Processing services; • Communication services

10.Performance Analysis
![Page 18: Case studies](https://reader034.fdocuments.in/reader034/viewer/2022051517/56815a69550346895dc7bbef/html5/thumbnails/18.jpg)
Analysis Approach
For the given type of analysis, the following input data is required:
• For each trigger the arrival frequency (average and possibly also peaks).
• For each process, function, or service the average service time.
• For each actor, component, or device the capacity.

Analysis ApproachGiven these inputs, we can estimate the following
performance measures:• For each concept in the model (service, process,
function, and resource) the throughput: the number of inputs/outputs that is to be processed per time unit. This is the workload that is imposed by the processes.
• For each actor, component, and device its utilisation: the percentage oftime that it is active.
• For each process, function, and service the average processing time and response time.
• For each client-to-client process the average completion time.
