Abstract: A disclosed example method to update a virtualized service involves comparing at least one node of a first service schema to at least one node of a second service schema based on at least one criterion, and finding at least one change in the at least one node of the second service schema relative to the at least one node of the first service schema based on the at least one criterion. The example method also involves updating a first node of a first virtualized service with a processor and without user intervention based on the at least one change while maintaining an association between the first node of the first virtualized service and data previously associated with the first node.

Abstract: A method for generating a performance simulation of a real service can include scheduling a time for a number of responses to be sent based on a number of response time metrics and determining a delay for the number of responses based on a number of data throughput metrics. The number of responses can then be sent based on the time and the delay.
