App platform - load balancing tcp traffic

Hello everyone,

Recently I’ve started using digital ocean app platform for setting microservice based architecture for my startup but I’m having issues with horizontal scalling.

At the time I have:

  • 1 main api that sends TCP commands to microservice
  • 1 microservice, but scaled horizontally to two instances of container

They are communicating through TCP, but the problem is that only one instance of microservice is used to do the hard work, the second one never gets any traffic.

What can I do with this situation?

Hi there,

The load balancing that comes with the App Platform is a built-in part that can’t be configured.

It is distributing incoming requests evenly across all containers that pass a health check and are tasked with providing capacity to your service.

Can you confirm that both of your instances are with status healthy and are passing the health checks?
