# Runtime Architecture (/docs/sombra/deploying/customizing-sombra/runtime-architecture)

Sombra is built to be run on x86-64 compute runtimes. There are ARM64 builds available for experimentation.

<Callout type="error" title="alpha-software-warning">
  ARM64-compatible Sombra builds are considered experimental, and not meant for Production usage. If you plan on using them in production deployments, please be aware of the limitations listed below.
</Callout>

## Limitations [#limitations]

ARM64 builds for Sombra have limitations around ODBC driver support for the following data systems:

1. IBM Db2
2. SAP Concur

If you require database connectivity to those database solutions, please use the production-ready x86-64 version of Sombra instead.

The experimental nature of ARM64 support also means that these builds are not tested as thoroughly as their x86-64 counterparts. As such, bugs are expected, and we might not always be able to address them, depending on the nature.

## Deployment [#deployment]

Simply add the `-arm64` suffix to the container image tag to pull the ARM64 image version.

```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
    name: sombra
    namespace: sombra
spec:
    template:
        spec:
            containers:
                - name: sombra
                  image: docker.transcend.io/sombra:latest-arm64
                  # Rest of the spec...
```

&#x20;When using the Transcend Helm Chart repository, set `image.tag: 'latest-arm64'` to pull ARM64 versions of the images.

<Callout type="warn" title="version-warning">
  Please be aware that Sombra container images older than October 2, 2026 (versions prior to v7.617.4) do not have ARM64 builds.
