In this blog post, we'll explore how to run self-hosted API Management (APIM) gateways in Azure Container Apps with Virtual Network (VNet) integration. This setup ensures secure and efficient API management within your network.

With Azure Container Apps we can run containerized applications, completely serverless. The platform itself handles all the orchestration needed to dynamically scale based on your set triggers (such ...

The part about Workload Profiles is particularly interesting - not everyone knows that you need to delegate the subnet to Microsoft.App/environments. Technical detail but fundamental!

A question for you: have you already tested this setup in multi-tenant scenarios or with APIs that handle unpredictable traffic spikes? It would be interesting to understand how auto-scaling behaves in real-world situations.

    Great questions—thanks for raising them!

    I’ve tested the setup under unpredictable traffic spikes using the scale-to-zero option, and it’s worked well so far. Azure Container Apps' dynamic scaling mixed with APIM’s resilience has handled bursty loads with minimal latency.

    I haven’t tested multi-tenant scenarios yet, but I agree—it’s a compelling angle. If you have a specific use case or architecture in mind, I’d love to explore it further.

    Appreciate the thoughtful feedback!
