Introduction As I am presently learning about MongoDB, I wanted to get some practice with the sharding and replication features of the database, which would require access to at least two running instances of MongoDB. Rather than running two seperate machines or doing something with virtualization, I wanted to keep it simple and get two instances running locally on my Fedora laptop. Here are the steps that I followed to get this working. Note that this tutorial assumes you already have one instance of MongoDB already installed, see my guide here for instructions on that. 1.

NoSQL

Why NoSQL? With the increase in web, mobile and IoT applications creating new classes of data, you as a developer would be re-evaluating how your data is stored and managed.

Irrespective of your company size, NoSQL as a database choice is growing by the day. NoSQL is simply the term used to describe a family of databases that are all non-relational. There are four types of NoSQL databases: Key-value stores, Graph stores, Column stores, and Document stores. The common thread amongst these NoSQL databases are: flexibility, scalability, availability, lower costs and special capabilities. The right NoSQL database can act as a viable alternative to relational databases or can be utilized in a complementary fashion along with existing systems.
