@bin who do you use to host your kubernetes? Specialist provider or u just installed that stuff on regular VM?
I use Google Container Engine (GKE) which provides native Kubernetes. Prior to that I have used a VM at Digital Ocean. Also have a PC at home I use a as Linux server to run Kubernetes, where I run development, testing and other non-trading related containers as Wordpress and MySQL, etc. Google has a nice deal which you get to run VM or containers for free during 60 days. No strings attached, the deal terminates after the trial period and nothing is charged.
AWS comes in handy if you need to scale up in heartbeat and then scale back down in another heartbeat. For example, if you want to collect every tick and every order for every symbol like FINRA does...
