Terminal 1 (simple webserver)

cd static
./webserver # or ./webserver.darwin-amd64 on a mac

Terminal 2 (zuul)

cd zuul
./mvnw clean package
java -jar target/zuul-0.0.1-SNAPSHOT.jar 

Terminal 3 (gateway)

cd gateway
./mvnw clean package
java -jar target/gateway-0.0.1-SNAPSHOT.jar 

Terminal 4 (linkerd)

cd linkerd
java -jar linkerd-1.3.4.jar linkerd.yaml

Terminal N (wrk)

install wrk

Ubuntu: sudo apt install wrk

Mac: brew install wrk

NOTE: run each one multiple times to warm up jvm
