#Loadtest
#LoadAndPerformanceTesting

I was at some point looking for a way to loadtest some of my environments, staging initially, but including production as well, ultimately, to ensure our ability to scale when facing sudden bursts of requests, and understand how it would impact our load balancers, our instances, our database server... etc.

I came across Loader.io , a service by SendGrid labs which not only allowed my team and I to loadtest our API endpoints but also simulate actual user traffic on our website.
