Here at BigDoor we strive to ensure our API is always running at peak performance, and yesterday we got a great performance boost with one small infrastructure change.

AWS is constantly improving their service and the performance of their platform, and yesterday afternoon the BigDoor team upgraded our API’s HTTP layer to the latest generation of Compute Optimized instances.

This fleet update alone resulted in an approximate 100ms decrease in average response time across our API!


Even though we bumped the instance size from c1.xlarge to c3.2xlarge to keep the same vCPU count, the instances are still cheaper than our old C1 fleet, they have more memory, and the performance is clearly better.

We have seen similar boosts in performance and cost savings across our entire infrastructure when using the latest class of instances, so if you’re still using the older classes anywhere in your systems, upgrade now!
