Experiments with different methods to proxy requests in Go to upstream URL

Experiments

Deploy a sample

Deploy a Golang HTTP function, which has the highest throughput. One exists already (alexellis2/gofast30-5-18):

faas deploy --image=alexellis2/gofast30-5-18 --name=gofast30-5-18

Also pass --gateway=$GW_URL

Deploy the proxy

Deploy the go-proxy-experiment on Kubernetes.

kubectl apply -f ./yaml/dep.yaml

Then pick a NodePort or LB:

kubectl apply -f ./yaml/nodeport-svc.yaml

# or

kubectl apply -f ./yaml/lb-svc.yaml

Collect results

Now try each variation of the proxy via a different route.

The $URL variable is the NodePort:31115 or LB:8080

Use http.Post

~/go/bin/hey -d "" -m POST -c 200 -n 20000 http://$URL/http-post?fn=gofast30-5-18.openfaas-fn.svc.cluster.local.:8080 -d test -m POST

Reuse the same client instance with http.NewRequest/http.Do:

~/go/bin/hey -d "" -m POST -c 200 -n 20000 http://$URL/client-post?fn=gofast30-5-18.openfaas-fn.svc.cluster.local.:8080 -d test -m POST

Use the reverse proxy implementation in OpenFaaS based upon http.NewRequest/http.Do:

~/go/bin/hey -d "" -m POST -c 200 -n 20000 http://$URL/faas-post?fn=gofast30-5-18.openfaas-fn.svc.cluster.local.:8080 -d test -m POST
