Configure Microsoft Defender for Cloud continuous export via Terraform
Microsoft Defender for Cloud supports the continuous export of a variety of data to Azure Event Hubs and Azure Log Analytics workspaces.

Implement rate limiting with Istio on Azure Kubernetes Service
In my last blog post I walked you through the setup of the rate limiting reference implementation: The Envoy Proxy ratelimit service. -> https://www.danielstechblog.io/run-the-envoy-proxy-ratelimit-service-for-istio-on-aks-with-azure-cache-for-redis/ Our today’s topic is about connecting the Istio ingress gateway to the ratelimit service. The first step for us is the Istio documentation. -> https://istio.io/latest/docs/tasks/policy-enforcement/rate-limit/ Connect Istio with the ratelimit service…

Run the Envoy Proxy ratelimit service for Istio on AKS with Azure Cache for Redis
The Istio sidecar proxy uses Envoy and therefore supports two different rate limiting modes. A local one targeting only a single service and a global one targeting the entire service mesh. The local rate limit implementation only requires Envoy itself without the need for a rate limit service. In contrast the global rate limit implementation…
