Modeling and Simulating Software Architectures: The Palladio Approach

understanding their internals

quality metrics are evaluated using probability distributions.

we need information about three properties of a system: first, the structure of the system, including components, interfaces, and their dependencies; second, the deployment describing the mapping of components and connectors to virtual or physical resources, including a description of these resources; third, the control and data flows through the s

Usage Model: The Usage Model defines how users interact with a system.

Component Allocation Model: The Component Allocation Model describes how components are deployed on hardware nodes.

Palladio is a software component modeling approach that focuses on the prediction of quality attributes of a software architecture.

Failure rate:

software design. It presents a language to describe software architectures and a simulator to make predictions of the influence of the architecture on performance and reliability.

Execution Environment Model: The Execution Environment Model defines hardware nodes and network and is described by the component deployer.
