MongoDB, a popular NoSQL database, can be self-managed or hosted and managed by MongoDB. In this guide, we'll briefly explain both options and then focus on using the managed version provided by MongoDB.

Self-Managed MongoDB

With self-managed MongoDB, you are responsible for setting up, configuring, and maintaining the database on your own servers or cloud infrastructure. This option gives you more control and flexibility over your database, allowing you to customize configurations according to your specific needs. However, it also requires a good understanding of database administration and infrastructure management.

Managed MongoDB by MongoDB Atlas

Managed MongoDB, offered by MongoDB through MongoDB Atlas, provides a cloud-based, fully managed solution. MongoDB Atlas takes care of the infrastructure, scaling, backups, and other administrative tasks, allowing you to focus on building and managing your application. It's a great choice for beginners or those who want a hassle-free, scalable, and secure MongoDB experience.

In this guide, we'll focus on using MongoDB Atlas, the managed version of MongoDB, for its ease of use and convenience.
