Keptn

Keptn is an open-source cloud-native control plane for automating delivery, operations, and remediation workflows for modern applications and infrastructure (categories: deployment automation, Site Reliability Engineering (SRE), observability, DevOps orchestration).

• Event-Driven Orchestration (EDO) of delivery, quality evaluation, and operations workflows across tools and services (DevOps orchestration).
• Automated quality gates based on service-level objectives and metrics from observability systems (SRE, observability).
• Progressive delivery support, including controlled rollouts and automated promotion or rollback decisions (deployment automation).
• Declarative configuration of sequences, tasks, and integrations via uniform specifications and shipyard definitions (configuration management).
• Extensible integration model via a cloud-native event protocol, enabling connection to Continuous Integration and Continuous Deployment (CI/CD), monitoring, and incident management tools (toolchain integration).

More About Keptn

Keptn addresses the problem of coordinating delivery, reliability, and remediation activities across heterogeneous DevOps and SRE toolchains. It functions as a cloud-native control plane that uses an event-driven model to orchestrate deployment pipelines, quality evaluations, and operational workflows. Instead of embedding logic directly into each tool, Keptn centralizes workflow definitions and delegates execution to integrated services through a standardized event protocol, which reduces coupling between pipelines and underlying platforms.

At the core of Keptn is its concept of “sequences” and “tasks” defined declaratively in a shipyard file (configuration management). This model allows platform and SRE teams to describe stages such as delivery, testing, evaluation, and remediation in a structured way. Keptn then emits and consumes events following its cloud-native event protocol (DevOps orchestration), coordinating specialized services for deployment, testing, metrics ingestion, and notification. This architecture separates control logic from execution and enables teams to replace or extend tooling without redesigning workflows.

Keptn provides automated quality gates based on service-level objectives and metrics collected from observability platforms (SRE, observability). The quality evaluation capability compares observed metrics against predefined thresholds or objectives and generates a score or evaluation result. This result can drive automated promotion, rollback, or additional testing steps in a progressive delivery scenario. Enterprises use this to standardize release criteria and to enforce consistent reliability checks across multiple services and environments.

In enterprise environments, Keptn operates as an integration and orchestration layer for CI/CD, monitoring, and incident management tools (toolchain integration). It connects to deployment systems, test tools, metrics backends, and collaboration platforms via services that implement the Keptn event protocol. This model supports scenarios such as blue/green or canary rollouts, automatic remediation actions triggered by failing SLOs, and coordinated incident workflows. Keptn is designed to run on Kubernetes and aligns with cloud-native practices (cloud-native infrastructure).

From a directory and taxonomy perspective, Keptn fits into categories such as deployment automation, DevOps orchestration, SRE automation, and observability-driven operations. Its capabilities center on defining and executing declarative sequences for software delivery and operations, integrating with external systems through events, and enforcing SLO-based quality checks. This positions Keptn as a control plane that enterprises can use to standardize and automate reliability-aware delivery processes across distributed microservices and multi-tool environments.
