  • General

    Can STACKIT Application Load Balancer run in networks without internet connection?

    No, STACKIT Application Load Balancer instances require network connectivity to the load balancer control plane via public endpoints.

  • Configuration

    Can I use a load balancing method other than Maglev?

    No, Maglev is the only supported load balancing method for STACKIT Application Load Balancer.

    Can I add an external service or a service from another project as a target?

    Yes, you need to set the disableTargetSecurityGroupAssignment option. You can find more details for target security groups in “basic concepts of the ALB”.

    Can I configure multiple listeners or ports?

    Yes, STACKIT Application Load Balancer supports multiple HTTP and HTTPS listeners on one assigned IP address.

    Can I use another load balancer in my project as a target?

    No, this is not supported due to internal design.

    Can targets in one target pool use different ports?

    No, all targets in a pool must use the same port.

  • Observability

    Is there logging and metrics for load balancers?

    Yes, log streaming is fully functional and supported for both the STACKIT Application Load Balancer (ALB) and the STACKIT Network Load Balancer (NLB). Read the Observability documentation to learn more.

    What types of logs can I expect to see from my load balancer?

    Standard outputs consist primarily of underlying Envoy proxy system logs. These include if envoy just started, if it stopped and if its healthy.

    Do you support logs for the Application Load Balancer firewall?

    Yes we do but for that, observability needs to be enabled first.

    Are logs generated specifically when an Application Load Balancer firewall rule is triggered?

    Yes. When an ALB Web Application Firewall (ALB WAF) reference is set on your listener, logs are dispatched every single time an enabled rule or log only rule is triggered by incoming traffic.

    Does the credentials reference lock me into using STACKIT Observability?

    No, there is absolutely no platform vendor lock-in. While the documentation deployment examples use STACKIT Observability profiles to highlight the native cross platform support, the underlying architecture relies on standard basic authentication. You can provide credentials and a custom PushURL for any target telemetry backend that accepts basic authentication, such as open-source Grafana Loki for logs or Prometheus for metrics instances.

    Do you provide some kind of dashboard for metrics?

    Yes, when setting up STACKIT Observability, you receive a Grafana Dashboard which you can directly access with your Project in the Portal.
