Available versions of MongoDB 4.x

There are a number of versions of MongoDB 4.x available, including the following:

• MongoDB Atlas and Stitch for the cloud environment
• MongoDB Enterprise Edition
• MongoDB Community Edition

The last product listed is free and tends to have a faster release cycle. Interestingly, MongoDB asserts that the Community Edition, unlike the model used by other open source companies, uses the same software pool for its beta versions as does the Enterprise Edition. The Enterprise Edition, when purchased, also includes support as well as advanced security features, such as Kerberos and Lightweight Directory Access Protocol (LDAP) authentication. 

Let's now look at the RAM, CPU, and storage requirements.
