Motivation
Runtime architecture
© sebis171108 Schäfer, Patrick - Master's Thesis final presentation 4
Necessity of knowledge about runtime architecture
▪ Detecting deviations from modeled architecture
▪ Compliance violations / SLA violations
▪ Semi-automated root cause analysis
▪ Semi-automated Impact analysis

Motivation
Problem statement
© sebis171108 Schäfer, Patrick - Master's Thesis final presentation 5
Problem:
Current discovery solutions don‘t own knowledge about the entire architecture including
dependencies between and within the architectual layers
Consequences
▪ comparison of modeled and runtime architecture
not possible across all layers
▪ root cause analysis is challenging and time consuming
▪ Incomplete impact analysis
Objective
▪ a system, that owns knowledge about all
realtime architecture components as well as
their inter- and intralayer dependencies

How to discover the Microservice Architecture by applying
distributed tracing?
What are component relationship types and how to discover them
automatically?
How to discover concurrency and synchronization?
How to recognize changes in the Microservice Architecture?
How to provide a smart user interface for adding business
semantic on top of business services?
