In this chapter, we will discuss operational aspects of MongoDB. Monitoring, backup, and security should not be an afterthought but rather a necessary process before deploying MongoDB in a production environment. In addition, monitoring can and should be used to troubleshoot and improve performance at the development stage.

Having a backup strategy that produces correct and consistent backups as well as making sure that our backup strategy will work in the unfortunate case that it is needed will be covered in this chapter. Finally, we will discuss security for MongoDB from many different aspects such as authentication, authorization, network level security, and how to audit our security design.
