One or more computing devices, systems, and/or methods for cost optimized services for dynamic service levels are provided. Components of a service are hosted across a first set of infrastructure tiers that satisfy a service level of the service at a first point in time. Costs associated with levels of computing resources provided infrastructure tiers are monitored. The service is monitored to dynamically detect a current service level of the service at a second point in time. One or more of the components are migrated to a second set of infrastructure tiers based upon the current service level of the service and costs associated with the second set of infrastructure tiers.
