The document provides an overview of the COLA project which aims to define a framework called MiCADO that supports optimal and secure deployment and run-time orchestration of cloud applications. The project has 14 partners from 6 European countries and will demonstrate the applicability of the MiCADO framework through large-scale pilots in SME and public sector use cases. It has a budget of 4.2 million Euros and runs from January 2017 to June 2019. The objectives are to design and test a set of services in the MiCADO framework, pilot and validate the technical and economic feasibility in case studies, and maximize impact through dissemination.
