How Can I Run Serverless Integrations in Kubernetes?

+1 for Knative Serving! It's super effective for your use case, especially with the recent release supporting scale-to-zero natively with HPA. Definitely give it a look!

Knative and OpenFaaS are excellent solutions for what you’re trying to achieve. They both support serverless functions that can scale to zero when idle, which fits your needs perfectly.

Yes, you can definitely do this! The most common options are Knative and KEDA. Knative Serving is designed for this purpose, automatically scaling to zero for HTTP requests. If an incoming request comes in and there are no pods running, it'll queue it, start a pod, and then redirect traffic once it's ready. KEDA is more event-driven but has an HTTP add-on that works similarly. Just a heads-up: while your Go services start instantly, Spring can take longer to boot up, so consider looking into GraalVM native images to speed that up. For your rolling deploys, you can automate the process: deploy a service, trigger it, test it, and let Knative or KEDA scale it back down once idle before moving on to the next service.

Knative is a great choice! In version 1.36, they will officially support scaling to zero naturally. It seems like it could work well for your scenario too.

For your setup on AKS, KEDA is often the simplest solution since you can use HTTP triggers to start pods as needed and scale down to zero when they’re not in use. Knative offers more traditional serverless features with request-based autoscaling. It's worth exploring both options depending on your specific needs!

You should check out KEDA; it allows you to scale based on requests. It provides a nice way to handle scaling in Azure Kubernetes Services. Here's a good starting point for KEDA: [Learn More About KEDA](https://learn.microsoft.com/en-us/azure/aks/keda-about).
