As we can see, this is a technology that deals with many aspects of distribution, be it data persistence or even computation. By leveraging these capabilities into our architecture, we are providing ourselves with a very simple scaling mechanism— just add more nodes. We are scaling up multiple aspects of our application simultaneously; in this way, we should hopefully not introduce any scaling imbalances that might have been present if we had just scaled one aspect independently.
In the next chapter, we will examine the different architectural setups that Hazelcast can operate in, the situations that suit the various options, and how to use them.
