The son of Hermes and LaBarbara Conrad, also an Openresty dynamic router.

Dwight Conrad

Dwight is 3scale answer to the need of routing HTTP/HTTPS traffic between different stacks. It is also used when we need to release new features to a selective group of users or when we need to move certain percentage of our customers to a new stack for maintenance reasons without losing the power to send them back to the old one. Heavily based on Openresty DynamicRoutingBasedOnRedis

Dwight is also the smallest son of Hermes Conrad, our Routing system on APItools, which is in charge of routing traffic between Docker Containers.
