Terms in this definition

• AKS

  Short for Azure Kubernetes Service, a managed Kubernetes offering that gives full control of clusters and node pools. Scaling uses the cluster autoscaler and Horizontal Pod Autoscaler; user sign-in is not built in.

• Ingress

  In Container Apps, turning this on exposes an app over TCP or HTTP, either to the internet or just within its environment, and no load balancer needs creating. AKS handles it differently: Ingress resources carry rules, and an ingress controller enforces them.

• Application Gateway

  Layer-7 load balancer deployed per region, offering URL-based routing, TLS offload, cookie-based affinity and an optional WAF.

• WAF V2

  Of the Application Gateway tiers, this one brings protection based on the OWASP Core Rule Set; Standard lacks any WAF, and the first-generation WAF tier reached retirement on 28 April 2026.

• MATCH

  Used in WHERE when querying SQL Graph, it describes how to walk from node to node through edge tables, with patterns written like p1-(f1)->p2.
