Konnect Cloud

ServiceHub Overview

ServiceHub is a Konnect Cloud functionality module that lets you catalog all of your services in a single system of record. This catalog represents the single source of truth of your organization’s service inventory and their dependencies.

Using ServiceHub, you can catalog, manage, and track every service in your entire architecture.

Services in the ServiceHub catalog

Each entry in ServiceHub is called a Service. This is the abstraction of one of your own upstream services.

A Service in ServiceHub breaks down into multiple configuration versions, and can be implemented to route to any endpoint you like.

Konnect Service diagram

  • Service: The abstraction of one of your own services. For example, it might represent a data transformation microservice or a billing API.
  • Service Version: One instance, or implementation, of the Service with a unique configuration. A Service can have many versions, and each version can have different configurations, set up for a RESTful API, gPRC endpoint, GraphQL endpoint, and others.
  • Service Implementation: The concrete, runnable incarnation of a Service version. Each Service version can only have one implementation.
Note: Currently, the only supported implementation type is a Kong Gateway runtime.

The main attribute of a Service version is its Upstream URL, where the service listens for requests. You can specify the URL with a single string, or by specifying its protocol, host, port, and path individually.

Kong Gateway implementations

When configuring a Kong Gateway implementation of a Service, you’ll need to specify a Route. Routes determine how (and if) requests get sent to their Services after they reach the API gateway. A single Service version can have only one implementation, but potentially many Routes.

After configuring the Service, version, implementation, and at least one Route, you’ll be able to start making requests through Konnect Cloud.

Dev Portal

ServiceHub natively integrates the Dev Portal into Service configuration. Admins can publish Services directly from ServiceHub to the Dev Portal, where application developers can search, discover, and consume existing Services.

The Dev Portal in Kong Konnect contains an API catalog, allowing you to document all of your Services and their versions.

Through ServiceHub, publish your Service to the Dev Portal and set up the following for any Service:

  • Markdown documentation: A description of your Service. Applies to every Service version.
  • Version spec: An OpenAPI (Swagger) document in YAML or JSON format. Applies to a specific Service version.

Kong Gateway plugins

Plugins can be configured to run in a variety of contexts, ranging from a specific Service version or Route to all Service versions. Plugins can execute actions inside Kong Konnect before or after a request has been proxied to the upstream API, as well as on any incoming responses.
