Agenda
The IBM Bluemix platform provides many tools and services for a modern IoT developer. I will showcase an application with simulated connected cars displayed on a map. I will also demo the geospatial analytics service and a simple node-red app for analytics.
IBM Bluemix
Bluemix is an open-standard, cloud-based platform for building, managing, and running applications of all types (iot, web, mobile, big data, cognitive, new smart devices, and so on).
Bluemix is an implementation of IBM's Open Cloud Architecture based on Cloud Foundry, an open source Platform as a Service (PaaS). Bluemix delivers enterprise-level services that can easily integrate with your cloud applications without you needing to know how to install or configure them.
For developers, Bluemix further optimizes the time you spend creating cloud application. You no longer have to be concerned about installing software or having to deal with virtual machine images or hardware. With a few clicks or keystrokes, you can provision instances of your applications with the necessary services to support them. This streamlining translates countless hours of setting up, configuring, and troubleshooting into time spent rapidly innovating and reacting to never-ending requirement changes.
Watson IoT Platform
Watson IoT Platform provides powerful application access to IoT devices and data to help you rapidly compose analytics applications, visualization dashboards, and mobile IoT apps.
With it you can perform powerful device management operations, and store and access device data, connect a wide variety of devices and gateway devices. Watson IoT Platform provides secure communication to and from your devices by using MQTT and TLS.
Watson IoT Architecture
Node-Red
Node-RED is a visual tool for wiring the internet of things – connecting hardware devices, APIs and online services in a new and interesting way. Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range nodes in the palette. Flows can be then deployed to the runtime in a single-click.
The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud.
Demo Introduction
The Connected Vehicle application we will configure and deploy has three components:
Node.js vehicle simulator HTML5 Map app HTML5 Tester app These three components use the IBM Internet of Things
Foundation (IoT Foundation) for real-time publish/subscribe messaging with the MQTT protocol. The simulated vehicles publish telemetry data frequently (two messages per second) and subscribe to a command topic whereby they accept commands (for example, "set speed to 60") from the tester application.
The Map app subscribes to the vehicle telemetry topic to display position and status in real time. The Tester app enables you to publish control commands to the vehicles and notifications to the Map app.
This overview diagram shows the relationships among the application's components:
