Having looked at all the basic services of OpenStack in the previous chapters, in this chapter we have discussed some optional services such as orchestration (using Heat) and metering (using Ceilometer), which will definitely be the next step for any enterprise when adopting OpenStack.

There are several other modules that are available in Juno, but we haven't discussed them here. These modules include Designate, Manila, and so on, which can be explored as you start playing with your OpenStack installation and get more comfortable.

With this, we come to the end of the installation and configuration of OpenStack components. In the next chapter, we shall look at various distributions and use cases of OpenStack.
