This short paper is an extension of my last article on ―Workload Analysis‖.
In addition to the workload distribution pattern, it‘s vital for a Performance Analyst to understand the topology-flow for all transaction types in-scope for performance testing. By now, you know that a transaction can be broadly classified as Online or Offline type. Online transactions are basically th e user interact ions with System Under Test (SUT) over the internet or intranet whereas some of the Offline transactions could refer to:
•
System background processes
•
Scheduled batch job
•
BOD / EOD executions
•
Any ETL processes
By topology-flow, what I mean is to be aware of various infrastructural components a business transaction interacts with from the time it gets into SUT as input till it is delivered as an output to the end user or client.
