Make it web scalable

To handle a lot of clients we must use something web scalable. Everyone of course heard cool stories about node.js. Some big companies such as Wallmart, Ebay, Groupon already moved from slow, old, nonscalable java to modern, fast and web scalable node.js. They cannot be wrong. So, we must too move from java to node.js.

### Benchmarks

Look at this:

![benchmark](https://raw.githubusercontent.com/schfkt/FizzBuzzEnterpriseEdition/master/images/benchmark.png "Amazingly fast and scalable node.js can handle a lot of requests")

This is amazing! So fast and damn scalable!

For that benchmark I used Apache Benchmark tool:
```
ab -n 50000 -c 1000 http://127.0.0.1:1337/
```

Let's compare it with java:

```
> ab -n 50000 -c 1000 java
ab: invalid URL
Usage: ab [options] [http[s]://]hostname[:port]/path
 ....
```

Java version doesn't work! It cannot handle a lot of requests, in fact it can't handle even one!

So, it is obvious that our migration from java to node.js is right choice.
