 ## Selecting a service
 A key step in the development process is selecting a service to connect your devices to. There are two primary Azure IoT service options for connecting and managing devices: IoT Hub, and IoT Central. 
 
-- [Azure IoT Hub](../iot-hub/about-iot-hub.md). Use Iot Hub to host IoT applications and connect devices. IoT Hub is a platform-as-a-service (PaaS) application that acts as a central message hub for bi-directional communication between IoT applications and connected devices. IoT Hub can scale to support millions of devices. Compared to other Azure IoT services, IoT Hub offers the greatest control and customization over your application design. It also offers the most developer tool options for working with the service, at the cost of some increase in development and management complexity.

 - [Azure IoT Central](../iot-central/core/overview-iot-central.md). IoT Central is designed to simplify the process of working with IoT solutions.  You can use it as a proof of concept to evaluate your IoT solutions. IoT Central is a software-as-a-service (SaaS) application that provides a web UI to simplify the tasks of creating applications, and connecting and managing devices. IoT Central uses IoT Hub to create and manage applications, but keeps most details transparent to the user.
