Can JMeter replace LoadRunner?

Putting price aside (LoadRunner having rather hefty licensing fees), many other reasons exist for retiring your LoadRunner tests and moving to JMeter.

Thick Client Required
LoadRunner requires a traditional, thick-click, Windows-only, IDE. Something else to install, manage and license by machine.

Have enough hardware on hand and available?

Beyond test creation, how about Load Generators? With LoadRunner, you have to create your own Load Generator infrastructure or lab.

Test Portability
LoadRunner tests, when not exported and re-compiled as Java (using yet another thick-click IDE), are in a proprietary format. You license expires? Maybe you can run using the community version—unless they require update—then you need the licensed version again to make modifications.

Appvance UTP Performance Cloud

Cloud-based Creation and Execution
The cloud-based platform provides browser-based test creation and management. Setup tests to execute and review results all from the same interface.

Cloud-based Load Generators
Forget about procuring your own Load Generators. Based on specified load, the appropriate number of Load Generators are spun up in Amazon EC2, Amazon’s cloud-based virtual servers. After tests run, and the systems are no longer needed, they stop until needed again.
Open Source Format

JMeter is Open Source, and continues to evolve with contributors around the world. The JMeter test format is also light weight, platform agnostic, and offers extensive protocol testing support.

Beyond JMeter
Pairing JMeter with Appvance UTP Cloud provides a cloud-based solution wiht increased scalability and in-depth reporting, but also provides browser-based recording for JMeter, UX Performance and Mobile Load tests.
