In this chapter, we completed a Zabbix setup in a three-tier environment. This environment is a good starting point to handle all the events generated from a large or very large environment.

In the next chapter, you will go deep into nodes, proxies, and all possible infrastructure evolution, and, as you will see, all of them are an improvement on the initial setup. This does not mean that the extensions described in the next chapter are easy to implement, but all the infrastructural improvements use this three-tier setup as a starting point. Basically, in the next chapter, you will learn how to expand and evolve this setup and also see how the distributed scenarios can be integrated into our installation. The next chapter will also include an important discussion about security in a distributed environment, making you aware of the possible security risks that may arise in distributed environments.
