Another round of team health checks is upon us

And I've learned a few things...

Terraform/Jmeter performance testing - practical experience

Over the last while we've had the opportunity to put our new Jmeter learnings to work.

Bug came up that was only evident under load - we were able to reproduce it in our dev environments!  The dev ran Jmeter off his laptop, and it was enough load to generate the bug.I think I mentioned last time about how the simple act of mapping out a Jmeter script revealed excess calls to our middleware - tickets were created to address this.QA has used it to help draw out issues with a new production environment, but... ...the other day they ran out of steam on their laptops.  So we got to come back to the Terraform/Jmeter setup we built a few months back.  Thankfully everything still worked, and we were quickly (15m) on our feet with 1 master and 6 slaves (c4.large) raising heck.
This is where I will talk about the lessons we learned today... Terraform is amazing and was totally worth the time investmentIf you are testing a cold production environment - ASK ABOUT HOSTS FILE CHANGES!!  We hammer…
