RECOMMENDATION: We recommend running Sitefinity CMS in a 64-bit IIS application pool when deploying your project.
When running Sitefinity CMS as a 32-bit process, by default, your application has a limit of 2GB virtual memory space. Under continuous high load, virtual space fragmentation can cause out of memory exceptions, forcing a recycle before the committed physical memory of the application reach the 2GB mark.

Run your Sitefinity CMS website in a cloud environment

You can run your website in any cloud environment that supports Windows Server role instances, such as Rackspace and Amazon AWS. In these scenarios, you can set up your website as part of a load balanced environment.

Auto-scaling in load balanced scenarios without the need to configure Sitefinity CMS is supported only for Azure App Service. In all other cloud IaaS providers, Sitefinity CMS supports Auto-scaling by utilizing Redis service.

For more information, see Deploy projects to Azure App Service and Load balancing.

Geolocation service

If you want to use Geolocation API, you must use Microsoft SQL Server or SQL Server Express.
