+# Palladio  - Modeling and Simulating Software Architectures
+
+Palladio is a software architecture simulation approach which analyses
+your software at the model level for performance bottlenecks,
+scalability issues, reliability threats, and allows for a subsequent
+optimisation. Palladio requires neither buying expensive executions
+environments nor fully implementing a software product.
+
+Palladio comprises:
+
+* The Palladio Component Model (PCM), a detailed meta-model of
+  component-based software architectures.
+* A component-based software development process. Palladio is aligned
+  with this process and enables distributed modeling for
+  component-based software development scenarios.
+* A software architecture simulator: Multiple performance,
+  reliability, maintainability, and cost prediction approaches are
+  combined. The approaches, by means of analysis or simulation,
+  calculate metrics (e.g. response time) from Palladio models
+  (instance of the PCM).
+* Tool support, the Palladio-Bench implements all aspects of Palladio.
+  The Palladio-Bench is extendable such that it can serve as
+  implementation base for new scientific directions.

+
+## Analysis
+Palladio supports a broad range of analysis scenarios. Each scenario
+can be analysed with respect to performance, reliability,
+maintainability, and costs. Palladio reduces the risks and implied
+costs of picking the wrong design decisions by a model-based
+engineering approach.
+
+Typical software architecture analysis scenarios are:
+* Sizing
+* Scalability
+* Load Balancing
+* Configuration Optimization
+* Design Alternatives
+* Extension of Legacy Software
+
+
+## Tools
+We have implemented an integrated modelling environment (called
+Palladio-Bench) based on the Eclipse IDE. It enables developers to
+create Palladio Component Model (PCM) instances with graphical editors
+and derive performance, reliability, maintainabilty, and cost metrics
+from the models using analytical techniques and simulation. The
+Palladio Component Model (PCM) is implemented using the Eclipse
+Modeling Framework (EMF). Using the Palladio-Bench, you model PCM
+instances, simulate models, view simulation results, and derive
+software design optimisations.
+
+The best way for getting started with the Palladio-Bench is looking
+through the screencasts and tutorials provided on our [official
+website](https://www.palladio-simulator.com/).
+
+## Research
+Palladio is a well-validated approach for the prediction of Quality of
+Service (QoS) properties of component-based software architectures. It
+enables the creation of high quality software architectures with
+dependable quality properties.
+
+Numerous publications demonstrate the applicability of Palladio for
+scientific and real-world industrial scenarios of different domains.
+The book ["Modeling and Simulating Software Architectures -- The
+Palladio Approach"](https://www.palladio-simulator.com/the_book/)
+presents the underlying methodology and background. Ongoing
+development effort and the continuous integration of latest scientific
+trends provides cutting-edge features to researchers and
+practictioners. More information on the scientific background of
+Palladio and developer information can be found in the [Palladio
+Developer
+Wiki](https://sdqweb.ipd.kit.edu/wiki/Palladio_Component_Model).
