Stepping back from the cluster

To avoid this situation we can separate our application away from the data cluster through the use of a thin client driver that looks and appears very similar to a direct Hazelcast instance; however, in this case, the operations performed are delegated out to a wider cluster of real instances. This has the benefit of separating our application away from the scaling of the Hazelcast cluster, allowing us to scale up our own application without having to scale everything together, maximizing the utilization efficiency of the resources we are running on. However, we can still scale up our data cluster by adding more nodes which will lead to a bottleneck, either for memory storage requirements or performance and compute necessities.

If we create a "server side" vanilla instance to provide us with a cluster of nodes we can connect out to from a client.

public class VanillaInstanceExample {
  public static void main(String[] args) {
    Config conf = new Config();
