# VFX Reference Platform compatibility The VFX Reference Platform is a common target platform for the VFX industry. To use the standard service-managed fleet Amazon EC2 instance running Amazon Linux 2023 with software that supports the VFX Reference Platform, you should keep in mind the following considerations when using a service-managed fleet. The VFX Reference Platform is updated annually. These considerations for using an AL2023 including Deadline Cloud service-managed fleets are based on the calendar year (CY) 2022 through 2024 Reference Platforms. For more information, see [https://vfxplatform.com/](https://vfxplatform.com/). **Note** If you are creating a custom Amazon Machine Image (AMI) for a customer-managed fleet, you can add these requirements when you prepare the Amazon EC2 instance. To use VFX Reference Platform supported software on an AL2023 Amazon EC2 instance, consider the following: + The glibc version installed with AL2023 is compatible for runtime use, but not for building software compatible with the VFX Reference Platform CY2024 or earlier. + Python 3.9 and 3.11 are provided with the service-managed fleet making it compatible with VFX Reference Platform CY2022 and CY2024. Python 3.7 and 3.10 are not provided in the service-managed fleet. Software requiring them must provide the Python installation in the queue or job environment. + Some Boost library components provided in the service-managed fleet are version 1.75, which is not compatible with the VFX Reference Platform. If your application uses Boost, you must provide your own version of the library for compatibility. + Intel TBB update 3 is provided in the service-managed fleet. This version is compatible with VFX Reference Platform CY2022, CY2023, and CY2024. + Other libraries with versions specified by the VFX Reference Platform are not provided by the service-managed fleet. You must provide the library with any application used on a service-managed fleet. For a list of libraries, see the [reference platform](https://vfxplatform.com/).
