Load generation from Australia

A few days ago Amazon announced the availability of its new AWS data center in Sydney, Australia. We here at Load Impact are now happy to announce that we have implemented support for load tests from the Sydney data center.

This means that we are now able to generate simulated user traffic from 8 different locations around the globe:

  • Palo Alto, California, USA
  • Portland, Oregon, USA
  • Ashburn, Virginia, USA
  • Sao Paolo, Brazil
  • Dublin, Ireland
  • Singapore, Singapore
  • Tokyo, Japan
  • Sydney, Australia

You are of course also able to use multiple locations where your traffic is generated, in a single load test. This is something unique to Load Impact that other services don’t offer.

Some other new things we have released recently include:

  • Parallel deployment of test configurations for large tests – This will drastically reduce the time it takes to start larger load tests. Where previously we configured all involved load generator cloud instances in a load test sequentially, we now configure them in parallel.
  • Graceful test shutdown – Previously, when a test was completed, the load generator instances would be killed abruptly. This meant that tests usually ended at the exact moment they were supposed to, but it also meant that some transactions that were “in transit” would never be recorded by Load Impact, even though they might appear in the logs on the web server. To make this less likely to happen, we have now started shutting down tests more gracefully than before, waiting a little bit for all simulated clients to be done with their current transactions. This means that while earlier, all clients in a test would just disappear when the test ended, you will now see a short ramp-down period where the number of clients ramps down quickly from whatever level you were at, to zero.
  • Various bug fixes and improvements – We have implemented lots of smaller bug fixes and improvements, for example in script validation, script conversion, user session handling, etc.
