A distributed computing system provides at least one service, and the service is provided by resources of the distributed computing system. Resources are represented by a topology graph including storage, application and database server nodes joined by edges indicative of relationships between nodes. Predefined parameters are monitored that are indicative of operating characteristics of the distributed computing system when providing the service. Values of the predefined parameters are compared with respective predetermined performance threshold values. The performance threshold values are determined based on a service level agreement (SLA). The SLA includes a service level objective (SLO). The performance threshold values are indicative of the respective operating characteristics prior to an event. Rules are provided for selecting a combination of application, storage and database server nodes to meet the SLO for each parameter of the parameter. Data associated with the set of rules are stored in the computing system.
