How to Create MongoDB Replication Clusters

Unlike relation database servers, scaling NoSQL databases to meet increased demand on your application is fairly simple – you drop in a new server, make a couple of config changes, and it connects to your existing servers, enlarging the cluster. All existing databases and collections are automatically replicated and synced with the other member nodes.

A replication cluster works well when the entire data volume of your database(s) is able to fit onto a single server. Each server in your replication cluster will host a full copy of your databases.

MongoDB is one of the most popular open source NoSQL database solutions available. Unlike relational databases that store rows of data, document oriented databases like this one store data as, you guessed it, documents. These types of databases are not constricted by rigid schemas. They also scale much easier and more efficiently than relational databases, meaning it is a lot easier to store once unthinkable amounts of application data.

MongoDB is able to achieve and maintain high performance – much greater than any relational database, such as Microsoft SQL – even while storing petabytes of data by offloading a lot of logic to your application. A relational database it is not, but this trade off gives are developers the flexibility they need to work with data in today’s high volume, big data world.
