Service API

Service Impl

• A Kapua Service exposes a interface and aobject model that conforms to a service blueprint

• Serializable Model Objects (JSON and XMLformats supported)

• Kapua Services can handle persistent entities• Kapua Services can raise/handle events for

choreography interactions• Support per tennant “scoped” configurations• Service implementations may optionally leverage

Kapua Commons Library to reduce the burdenof implementation

• A service defines a bounded context • All interactions between services are handled

through the Kapua Service interfaces• Can manage resources• No resource sharing between modules

Kapua Commons

Eclipse Kapua Deployment

• Applications provided:– Web Console– RESTful API– Multiprotocol Messaging– Service Event Bus[1]

• Provide extension points for:– Web Console– RESTful API

• Data tier:– NoSQL Schema Less Engine (Elasticsearch)– Multiple SQL DB Support – Support for Database Migrations

• Provides demo deployments for:– Plain Docker Containers– Orchestrated Dockers (OpenShift Origin)– Virtual Machines (Vagrant)

Message Broker

RESTful API

Admin Console

Event Bus[1]

• Note:

1. Available with next release (1.0.0)

OpenID Auth Providers

Message Routes

• The REST API allow programmatic access to theplatform. It exposes all the platform functionality,including, tennant management, devicemanagement and data management.

• The Message Routes allow routing of telemetrydata to a wide range of destinations.

• The Event Bus allow both backend services andexternal applications to react to relevant eventstriggered

• Kapua supports authentication via OpenID.OpenID service providers can be used out of thebox to provide authentication services

• Services advertise themselvesto the service discovery

• Service discovery is delegatedto the Locator

• Client code is agnostic of thelocation of the services it uses

• Client code is agnostic of theprotocol used to communicatewith the microservice

• Should have minimalassumptions on the containermodel

JMS 2.0 – AMQP 1.0

JMS 2.0 – AMQP 1.0

EventBus

• Backend services should be able to exchange Events to react tochanges in the global status of the backend

• Service Events are raised upon the execution of a servicemethod

• Event management guarantees that the global status of thesystem is eventually consistent
