Hardware and Software Requirements for BizTalk Server 2020

Hardware requirements

The following table lists the minimum hardware requirements for your BizTalk Server computer. In a production environment, the volume of traffic may require greater hardware requirements for your servers.

  • Computer and processor: A computer with an Intel Pentium-compatible CPU that is:

    • 1.4 GHz or higher

    Hyper-threading and multi-core processors are supported.

    The 64-bit versions of BizTalk Server require a 64-bit operating system running on an x64-based system. Computers based on CPUs that are compatible with the AMD64 (x86-64) and Extended Memory 64-bit Technology (EM64T) processor architecture are considered x64-based systems.

    BizTalk Server is not supported on Itanium-based systems.

  • Memory: 4 GB or more

  • Hard disk: 10 GB of available hard disk space for a complete installation, including the operating system and all prerequisite software. The hard disk must be NTFS formatted.


The hardware requirements listed are the minimum. Every environment is different and there's a very good chance that your environment may need more depending on your throughput requirement and load. See Recommendations for Installing, Sizing, Deploying, and Maintaining a BizTalk Server Solution. Also refer to Windows System requirements for Windows Server 2016 and Windows Server 2019.
