Keda
Keda (Kubernetes Event-driven Autoscaling) is an open-source platform that enables event-driven autoscaling for Kubernetes workloads. It automatically scales applications in a Kubernetes cluster based on events from various sources, such as message queues, databases, or custom metrics, without requiring manual intervention. This allows applications to efficiently handle varying loads by dynamically adjusting the number of pods.
Developers should use Keda when building microservices or serverless applications on Kubernetes that experience fluctuating traffic, as it optimizes resource usage and reduces costs by scaling down during low demand. It is particularly useful for event-driven architectures, such as processing data from Kafka or RabbitMQ, where scaling needs to respond to incoming events in real-time.
