KEDA

KEDA (Kubernetes Event Driven Autoscaling) is a CNCF graduated application autoscaler that drives scaling of any container in Kubernetes based on the number of events needing to be processed. It extends Kubernetes with custom resources for defining scaling behavior and supports over 50 built-in scalers for event sources including Kafka, RabbitMQ, AWS SQS, Azure Service Bus, and Prometheus.

KEDA publishes 2 APIs on the APIs.io network: Metrics API and CloudEventSource API. Tagged areas include Autoscaling, CNCF, Event-Driven, Graduated, and Kubernetes.

The KEDA catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 2 Spectral governance rulesets.

KEDA’s developer surface includes authentication, documentation, getting-started guide, engineering blog, changelog, Stack Overflow tag, and 12 more developer resources.

  name: KEDA Metrics API
  description: External metrics API server that exposes event-driven metrics from configured scalers to the Kubernetes Horizontal
    Pod Autoscaler. It implements the Kubernetes external metrics API interface, allowing the HPA controller to query scaler-derived
    metrics when making scaling decisions.

  name: KEDA ScaledObject API
  description: The ScaledObject custom resource defines the mapping between an event source and a Kubernetes Deployment, StatefulSet,
    or custom resource that should be scaled based on event metrics. It specifies trigger scalers, scaling thresholds, min/max
    replica counts, and cooldown periods for workload-based autoscaling.

  name: KEDA ScaledJob API
  description: The ScaledJob custom resource defines the mapping between an event source and Kubernetes Jobs that should be
    created in response to events. Unlike ScaledObject, ScaledJob creates new Job instances to process each unit of work rather
    than scaling existing long-running deployments, making it suited for batch workloads.

  description: The TriggerAuthentication and ClusterTriggerAuthentication custom resources define authentication parameters
    for KEDA trigger scalers, allowing credentials to be sourced from Kubernetes Secrets, environment variables, pod identity
    providers such as AWS IRSA or Azure Workload Identity, or HashiCorp Vault without embedding them in the ScaledObject.

- aid: keda:keda-cloud-event-source-api
  name: KEDA CloudEventSource API
  description: The CloudEventSource and ClusterCloudEventSource custom resources define HTTP or Azure Event Grid destinations
    where KEDA delivers CloudEvents when scaling events occur. Events follow the CloudEvents specification v1.0 and carry
    reason codes and messages for events such as ScalerError, ScaledObjectReady, ScaledObjectDeleted, and AuthenticationFailed.
    Optional event type filters allow consumers to subscribe to only the events they care about.
