Monitoring, backup, and security should not be an afterthought, but 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.

In this chapter, we will discuss the operational aspects of MongoDB. 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 a backup is needed, will be covered in this chapter. Finally, we will discuss security for MongoDB for many different aspects, such as authentication, authorization, network-level security, and how to audit our security design.

This chapter will focus on the following three areas:

• Monitoring
• Backup
• Security
