 # What Azure technologies and services can you use to create IoT solutions?
 
 Azure IoT technologies and services provide you with options to create a wide variety of IoT solutions that enable digital transformation for your organization. For example, you can:
 
-* Use [Azure IoT Central](https://apps.azureiotcentral.com), a managed IoT application platform, to build and deploy a secure, enterprise-grade IoT solution. IoT Central features a collection of industry-specific application templates, such as retail and healthcare, to accelerate your solution development process.
+* Use [Azure IoT Central](https://apps.azureiotcentral.com), a managed IoT application platform, to evaluate your IoT solution.
 * Use Azure IoT platform services such as [Azure IoT Hub](../iot-hub/about-iot-hub.md) and the [Azure IoT device SDKs](../iot-hub/iot-hub-devguide-sdks.md) to build a custom IoT solution from scratch.

 # What is the right IoT solution for your business?
 
-To build an IoT solution for your business, you typically choose to use either the *platform services* or the *managed app platform* approach.
+To build an IoT solution for your business, you typically evaluate your solution by using the *managed app platform* approach and build your enterprise solution by using the *platform services*.
 
-Platform services provide the building blocks for customized and flexible IoT applications. You have more options to choose and code when you connect devices, and ingest, store, and analyze your data. Azure IoT platform services include the products Azure IoT Hub and Azure Digital Twins.
+Platform services provide all the building blocks for customized and flexible IoT applications. You have more options to choose and code when you connect devices, and ingest, store, and analyze your data. Azure IoT platform services include the products Azure IoT Hub and Azure Digital Twins.
 
-A managed app platform lets you get started building apps more quickly than platform services by reducing the number of decisions needed to achieve results. The managed app platform takes care of most elements of your solution, so you can focus on adding industry knowledge, and scaling and connecting devices. Azure IoT Central is a managed app platform.
-
-To choose between these two approaches, you should consider:
-
-- How you want to manage your solution.
-- What level of customization and control you want over your solution.
-- What pricing structure you want.
+A managed app platform lets you quickly evaluate your IoT solution by reducing the number of decisions needed to achieve results. The managed app platform takes care of most infrastructure elements in your solution, so you can focus on adding industry knowledge, and evaluating the solution. Azure IoT Central is a managed app platform.
 
 ## Management
 
-Where do you want to spend your system management time and resources? 
+The platform services give you full control over the underlying services in your solution. For example:
 
-- Choose the platform services approach to have full control over the underlying services in your solution. For example, you want to:
+- Scaling and securing services to meet your needs.
+- Using in-house or partner expertise to onboard devices and provision services.
 
-    - Manage scaling and securing services to meet your needs.
-    - Make use of in-house or partner expertise to onboard devices and provision services.
-
-- Choose the managed app platform approach to take advantage of a platform that handles scale, security, and management of your IoT applications and devices.
