I'm building an Azure AI Foundry environment, but Anthropic models aren't available in my region. At the moment, the only regions I can find with availability are Sweden Central and East US 2. My understanding is that the newer Foundry experience has not rolled out Anthropic model access to many regions yet.
Would it be practical to deploy the Foundry resource in Sweden Central and access it from my normal Azure region? The broader design would involve running the Claude Agent SDK in Azure Container Apps locally, while using Foundry in Sweden Central for model access. I'd potentially move everything back to the local region once Anthropic models become available there.
I'm also trying to understand how this affects the Foundry Playground, API access, quota, networking, security, data processing, and data residency. In particular, I've heard that Sweden Central may only offer a Global deployment option, which could allow data to be processed outside Sweden, possibly including the United States. Quota and capacity also seem uncertain.
We are committed to Azure, so switching platforms is not ideal. Is the cross-region Foundry approach technically and operationally sound, or are there important limitations and compliance issues I should account for?

We considered using Sweden Central, but the available deployment was Global rather than Data Zone. That meant requests could potentially be processed outside Sweden, including in the United States, which was unacceptable for our clients. Capacity was also uncertain, and we had to use a different region for another model because the preferred region had no capacity. Make the residency and capacity checks a formal go/no-go requirement before building around this.
For projects where Anthropic is mandatory and the Azure deployment constraints cannot be accepted, another managed Anthropic service may be the more predictable option. That is difficult if the organization must remain entirely on Azure, but the trade-off is clearer than designing around a region that may lack capacity, require a reservation, or route data globally.
The bigger practical issue appears to be capacity and quota. Even in a supported region, availability may be limited and you may need Microsoft to approve quota or commit to reserved capacity. That makes Sweden Central a risky dependency for a production design unless you have written confirmation of model availability, capacity, and the data-processing behavior you require.
A cross-region setup may work technically, but the region where the model deployment lives is not the only location that matters. Check whether the deployment is Global or Data Zone. A Global deployment can route requests through other regions, so it may not satisfy strict residency or sovereignty requirements even if the Foundry resource itself is in Sweden Central. You’ll also need to confirm networking, logging, telemetry, retention, and the terms that apply to Anthropic models specifically.
Running the Agent SDK in Container Apps in your preferred region while calling a Foundry model deployment elsewhere is a reasonable architecture in principle. Treat the Foundry endpoint as a cross-region dependency, though: validate private connectivity, outbound access, latency, failure handling, identity, and where prompts, responses, diagnostics, and traces are stored. The Playground can be useful for a proof of concept, but it does not prove that the complete Agent SDK and production integration will meet your requirements.
That is the main constraint for us—we need to stay on Azure. I’m also confused by the differences between the older and newer Foundry experiences, since the older interface appears to allow a Sweden deployment even though the newer setup has much more limited regional availability.
