All YaCy components are microservices which can be deployed i.e. using Docker or other application hosting methods which are provided as cloud services from many different providers. A YaCy grid will scale with the number of microservices that connect to a common broker. That broker is the MCP, this application. For a full enterprise-integration installation, the operator has to start and support a ftp server, a rabbitmq and an elasticsearch. However, all of them can be omitted and the MCP will provide all of these services with built-in functions. For database operations and message storage a MapDB is used, asset files are stored in a local data directory.
