This information is useful to ensure that your development environment is compatible with the deployment process and the Azure resources.
Previous knowledge of cloud-based development, and Microsoft Azure in particular, is valuable to get the most out of DXP. See [Microsoft Azure](🔗) to learn more.
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.
