RedLine13 brings load testing to the Cloud. It provides a free (almost) service that helps to setup and deploy load testing instances in Amazon account. Payment has to be done for the load testing part of this on the spot instances - hence the ‘almost’. For example, when running a load test with 200 m1.small Load Agent Servers, hitting the application or site, you can manage them as spot instances and it will cost about $2.00 for an hour. This will allow you to emulate 50,000 users continuously, providing load. RedLine13 provide you with real-time graphs and reports for which no payment is required.
This user guide explains how developers and testers can perform load testing of their applications using RedLine 13 tool. It also addresses, how JMeter can be interested with RedLine13.
