This information is useful to ensure your development environment is compatible with the deployment process and the Azure resources.

## What should I know before using DXP?

- See [Microsoft Azure](https://azure.microsoft.com/en-us/) to gain knowledge of cloud-based development, particularly Microsoft Azure, which is valuable for getting the most out of DXP.
- Ensure that you use [compatible versions of software, services, and tools](docId\:EbFCNo6K0wQHK--V4b_tz)  for a smooth deployment procedure.
- [Create an Optimizely cloud account](docId\:X-MjgQs-93BregnBOiaQI) to access the [self-service capabilities for DXP](docId\:O4YrBd-sHXoEQsTLu6v-z) and information about your [projects in the Azure portal](docId\:BNuzWffvzlfed0Yyu5u9l).
- Check the [system requirements](docId\:EbFCNo6K0wQHK--V4b_tz) before installing. Easy [installation](docId\:VuiU-K4aAR6ISGicFg4lk) and service onboarding, sample templates, and Visual Studio extensions help you get your development projects up and running. With Optimizely's continuous releases, see [Optimizely Release Notes by Product](docId\:HGD5VgCYvoRctY9RmhkMD) to keep projects up-to-date with a shorter time-to-market for customer solutions.

* **Note**
  You can run *only one Web Application* (ASP.NET Web Application project) in your DXP solution. However, you can have unlimited number of *sites* in that application.
* To ensure maximum availability and scaling flexibility, Optimizely Search & Navigation (formerly Find) uses dynamic IP ranges. For example, if you require approval lists for IP addresses in the firewall, make sure that your firewall supports domain-based approval lists.

The following overview shows the **minimum required versions** for Optimizely products and modules, and tools and services for deploying to the integration environment.
