MODELING DISTRIBUTION AND FAILOVER DATABASE CONNECTIVITY BEHAVIOR

Aspects of the subject matter described herein relate to database connectivity behavior. In aspects, an entity seeking to access data that is replicated via instances of a database follows a plan. The plan provides information as to which instance(s) the entity is to attempt to access the data from. The plan may include connection data that indicates parameters the entity is to use in connecting to the instance(s). The plan may also indicate one or more other instances from which the entity may attempt to access the data if the client is not able to access the data from initial instance(s).
