Keda, short for Kubernetes-based Event-Driven Autoscaling, is an open-source project that provides event-driven autoscaling for your Kubernetes workloads.
It stands out in the cloud computing and DevOps realms due to its ability to scale applications in response to real-time events rather than just static metrics. This innovative technology allows Kubernetes clusters to efficiently manage resources, scaling workloads up or down based on actual demand, which can significantly optimize costs and performance.
Keda integrates seamlessly with a variety of event sources, including message queues, database changes, or even custom metrics, making it highly versatile and adaptable for different use cases. Its importance in modern cloud-native environments cannot be overstated, as it empowers developers and organizations to build more responsive, efficient, and cost-effective applications in Kubernetes.
This feature-rich autoscaler is a game-changer in the world of container orchestration, driving the evolution of cloud infrastructure towards more dynamic and intelligent resource management.
Orchestration systems decide where and when workloads run on a cluster of machines (physical or virtual). On top of that, orchestration systems usually help manage the lifecycle of the workloads running on them. Nowadays, these systems are usually used to orchestrate containers, with the most popular one being Kubernetes.
There are many advantages to using Orchestration tools:
