Istio Gateway vs Kubernetes Ingress
WHAT IT TESTS: edge traffic models. OUTLINE: Ingress is a simple built-in L7 entry abstraction; an Istio Gateway configures only ports and hosts at the edge while VirtualServices do routing, unlocking mesh features.
WHAT IT TESTS: that you know how each handles edge ingress and their division of labor. ANSWER OUTLINE: Ingress is a native Kubernetes resource bundling host and path routing plus TLS, implemented by a controller. An Istio Gateway only declares the ports, protocols and hosts to expose at the mesh edge; routing is delegated to VirtualServices, giving you weighted splits, retries and mTLS. Use Ingress for simple needs; use Gateway plus VirtualService when you already run Istio and want advanced traffic control.
