Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Rancher

  • Another platform to run and keep available, and an outage in it affects access to everything it manages
  • Meaningful overhead if you only operate one or two clusters
  • Version compatibility between Rancher and managed Kubernetes versions needs watching during upgrades
  • Support requires a SUSE subscription; the project itself is community-supported

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier
