Pros / Cons
  • Its modular and flexible approach allows us to adapt it to the real needs of our business without having to build security solutions from scratch.
  • The only thing that i don't like but is very understandable is that some advanced configurations require deep documentation digging.

  • The installation and maintenance process is straightforward, especially that they've provided a Helm chart that can be deployed directly to a Kubernetes cluster. When I first installed it, v1.15.8 required Elasticsearch. But in v1.16.0 and newer, Elasticsearch is optional so it's much easier to get started especially for those with less than 10,000 users.
  • difficult to deploy on k8s if we really need to expose it (we did not succeed in that; however it's no problem for us, because we don't expose fusionauth any more)
