Ok, I have my server built on ec2. My stack is Nginx as a load balancer, supervisord for managing processes for node.js i.e. one process for each cpu, and redis, master and slave on separate boxes. I have stress tested by testing failover and taking services offline. Using apache AB, on the server I can get up to 6500 QPS.
Now, I need to load test remotely. What are the best open source tools to accomplish this or even the most cost effective SaaS method to do this. I do expect 6500 QPS per server in production and need to extend the isolation of apache AB to remote testing. E.g. I will have servers in singapore and I need to test 6500 QPS from Japan and the effect of latency. I am aware of apache Jmeter but looking for a best practice solution.
Thanks
I have successfully used jMeter for load testing at significant scale.
If a single load generation client cannot output enough load, you can configure jMeter with multiple load generation clients, with the load coordinated by a master instance.
Using “open source tools” implies that you have the ability to spin up servers in the zones you’re interested in (e.g. Japan). If you locate a cloud provider in that region, you can spin up as many load generation instances as needed. You may, however, need quite a few instances depending on the network connectivity offered to individual instances. The nice thing about jMeter is that it can coordinate many load generation instances.
