Introduction

MongoDB is a document data store that has been around for almost a decade already. During the past five years MongoDB evolved into a mature product that features enterprise grade features like scalability (sharding), security and resilience. Not all of these features in the MongoDB Enterprise version are generally available for the public. However with the recent improvements made on the Percona version of MongoDB, some of these feature are now available. With the addition of third party components and storage engines, like RocksDB, the ecosystem of MongoDB has become a flourishing one.

In this whitepaper we will shed a light on choosing the right version for your cluster and cover the basics of preparing MongoDB for production.
