This open access book provides an overview of the work developed within the SODALITE project
which aims at facilitating the deployment and operation of distributed software on top of
heterogeneous infrastructures including cloud HPC and edge resources. The experts
participating in the project describe how SODALITE works and how it can be exploited by end
users. While multiple languages and tools are available in the literature to support DevOps
teams in the automation of deployment and operation steps still these activities require
specific know-how and skills that cannot be found in average teams. The SODALITE framework
tackles this problem by offering modelling and smart editing features to allow those we call
Application Ops Experts to work without knowing low level details about the adopted
potentially heterogeneous infrastructures. The framework offers also mechanisms to verify the
quality of the defined models generate the corresponding executable infrastructural code
automatically wrap application components within proper execution containers orchestrate all
activities concerned with deployment and operation of all system components and support
on-the-fly self-adaptation and refactoring.
