+# Palladio
+
+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. 
+Construction rules are automatically checked by Palladio and thus allow optimal software architectures without costly trial-and-error-cycles. 
+Like in other engineering disciplines, Palladio enables software engineers to construct software straight and in the right way.
+
+Palladio comprises:
+
+* The Palladio Component Model (PCM), a detailled meta-model of component-based software architectures.
+* A component-based software development process (PDF). 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.
+You can easily derive the right software architecture design decisions using Palladio. 
+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. 
+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).
