An update system is provided that generates a service list of services and sorts the services in the service list from least dependent services to most dependent services. Services that are unaffected by updates as determined based on the sorting are removed. An update runbook is generated with steps for updating the services. An order of the steps is based on the sorted service list, and the steps indicate target services, hosting machines and actions to perform on target services.

Updating dependent services

An update system is provided that performs a stop of that service at each machine that hosts that service such that a service that is dependent on another service stops before that other service starts performing a stop. After a machine hosting a service stops, the update system performs an update of that service on that machine. The update system then performs a start of that service at each machine that hosts that service such than a service that another service depends on starts before that other service starts performing a start.
