6. At runtime each Role will execute on one or more instances A role instance is a set of code, configuration, and local data, deployed in a dedicated VM Roles are defined in a Hosted Service A role definition specifies: VM size Communication Endpoints Local storage resources etc.

26. More small instances == more redundancy Some scenarios will benefit from more cores Where moving data >$ parallel overhead E.g. Video processing, Stateful services (DBMS) Don’t just throw big VMs at every problem Scale out architectures have natural parallelism Test various configurations under load
