The document describes the DBE Execution Environment, which is a platform for small and medium-sized businesses across Europe. It consists of an integrated, distributed network of local digital ecosystems that allow businesses and local governments to cooperate by exchanging resources, applications, services, and knowledge dynamically. The environment is self-managed without a single owner or point of failure. It uses game theory, diffusion-reaction models, and other techniques to emerge organically. Services are deployed in containers called ServENTS that provide security, filtering, and other capabilities.
