Hi Anthony1db
Hoping you are doing well!
Well They are both user for Performance Testing, buy PC isthe Enterprise Version of LoadRunner, So it suits tlarge companies who need to run performance testing for mutiple projects at the same time without the poblem of shareing a Controller or purchasing duplicate licences.
LoadRunner Controller(s) ca be standalone or act as a Controller node as part of a larger performance center architecture. Performance Center replaces your user interface with a web-based console for your activities.
Also Performance Center is simply Loadrunner wrapped up in a web front end. By wrapping up the LoadRunner components into a web front end it means the service can almot be treated as a Software as a Service.
Approaches:
1. Anyone within a organisation can gain access to the software, particularly useful if you are a global and distributed entity.
2. Reduce the license costs of implementing LoadRunner within large organisations.
3. Allow global Centers of Experience to standardise approaches and consolidate hardware.
4. The HP Performance Center software can be centrally administrated.
A main advantage of HP Performance Center over LoadRunner mainly reduce the cost. So installing LoadRunner on 'x' performance testers PC's will be a lot more expensive than sharing it as a resource between them through Performance Center.
Please let us know if this information was useful.
Thanks and Regards,
