Architecture

Istio traffic shifting/routing

• K8S native RR routing

make demo1-weight-native                # run to deploy
make demo1-weight-native-clean          # run to remove

• Istio weight routing for backends system (REST)

make demo2-weight-identity-istio       # run to deploy
make demo2-weight-identity-istio-clean # run to remove

• Istio weight routing for frontend SPA, Static HTML, etc..

make demo3-weight-nvui-istio           # run to deploy
make demo3-weight-nvui-istio-clean     # run to remove

• Istio routing based on HTTP headers

make demo4-routing-header              # run to deploy
make demo4-routing-header-clean        # run to remove

• Istio Load balancer - Consistent Hash (header/source ip)

make demo5-lbhash                      # run to deploy
make demo5-lbhash-clean                # run to remove
# for testing: uuidgen
# for testing: watch -n0.5 -d -c "curl -H 'x-app-test: REPLACE_WITH_UUID' -s http://identity.nemo/v1/system/info | jq . -C "

Istio traffic resilience

• Istio fault injection - delays

make demo6-delay                       # run to deploy
make demo6-delay-clean                 # run to remove

• Istio fault injection - abort

make demo7-abort                       # run to deploy
make demo7-abort-clean                 # run to remove

• Istio circuit breaker

make demo8-cb                          # run to deploy
make demo8-cb-clean                    # run to remove

• Istio traffic mirroring & debugging

make demo9-mirror                      # run to deploy
make demo9-mirror-clean                # run to remove

Istio authorization

• RBAC

make demo10-rbac                       # run to deploy
make demo10-rbac-clean                 # run to remove

Istio Envoy filters

• Envoy Lua filter

make demo11-filters                    # run to deploy
make demo11-filters                    # run to remove
