Introduction

Overview​

Klutch is a Kubernetes-native platform that simplifies the orchestration of resources and data services across diverse cloud environments and multiple Kubernetes clusters. It enables on-the-fly provisioning of services by multiple application Kubernetes clusters using a declarative interface. It caters to both the needs of platform operators and application developers, as it simplifies both the hosting as well as the consumption of data services.

Key Features​

  • Multi-cluster Management: Orchestrate resources and data services across many Kubernetes clusters.
  • On-demand Provisioning: Allow App Clusters to provision services dynamically as needed.
  • Declarative Interface: Utilize a unified Kubernetes-native declarative approach for data service provisioning and consumption.
  • Unified Control: Manage resources and data services across multiple environments from a single point.
  • Dual-focused Design: Simplify operations for both platform operators and application developers.
  • Extensible Architecture: Plugin-based architecture facilitates easy integration of new resource types and cloud providers.

Overview of System Architecture and Developer/Operator Interactions​

  1. Developers

    • Interact with their Kubernetes clusters to request and use remote resources.
    • Define data service requirements using Custom Resources, initiating automated provisioning and deployment processes.

  2. App Clusters

    • Request services from the Control Plane Cluster.
    • Utilize Klutch-bind to subscribe and enable usage of Klutch's APIs across different Kubernetes clusters.
    • Synchronize resource specifications, status, and additional information with the Control Plane Cluster.

  3. Platform Operators

    • Configure and manage available remote resources through the Control Plane Cluster.
    • Oversee the entire system, ensuring smooth operation.

  4. Control Plane Clusters

    • Manage the entire ecosystem using the centralized control plane.
    • Process service requests from App Clusters.
    • Utilize Crossplane for managing and provisioning cloud-native resources across multiple cloud providers and on-premise environments.
    • Manage bidirectional synchronization of resource specifications, status, and additional information with App Clusters.
    • Key functionalities include:
      • Maintain a list of available resources.
      • Handle the actual provisioning of resources in target environments.
      • Provide system-wide observability.

  5. Cloud Providers & On-Premise Infrastructure

    • Serve as the actual environments where resources are provisioned.
    • Support hybrid and multi-cloud deployment models.
