This project is an Event server designed to be deployed to a Google Compute Instance and handle
websocket connections.

You can run it directly in your IDE by creating a run configuration that uses the main class `io.vertx.core.Launcher`
and passes in the arguments `run com.universeprojects.eventserver.MainVerticle`.

The build.gradle uses the Gradle shadowJar plugin to assemble the application and all it's dependencies into a single "fat" jar.

To build the "fat jar"

    ./gradlew shadowJar

To run the fat jar:

    java -jar build/libs/gradle-verticle-3.3.3-fat.jar

(You can take that jar and run it anywhere there is a Java 8+ JDK. It contains all the dependencies it needs so you
don't need to install Vert.x on the target machine).

Now point your browser at http://localhost:8080

Writing code in verticles allow you to scale it more easily, e.g. let's say you have 8 cores on your server and you
want to utilise them all, you can deploy 8 instances as follows:

java -jar build/libs/gradle-verticle-3.3.3-fat.jar -instances 8

You can also enable clustering and ha at the command line, e.g.

java -jar build/libs/gradle-verticle-3.3.3-fat.jar -cluster

java -jar build/libs/gradle-verticle-3.3.3-fat.jar -ha

Please see the docs for a full list of Vert.x command line options.
