What is MongoDB?

MongoDB is an open-source document-oriented database. MongoDB is a NoSQL database. It is written in C++. MongoDB is a free and cross-platform database. The community version of MongoDB is free and do not need to pay for the license. The paid version gives you support and access to some proprietary tools that makes it easy to work with the database.

Features of MongoDB are:

  1. Distributed database
  2. Highly available NoSQL database
  3. Supports horizontal scaling (Different parts of database table are distributed across multiple mongodb instances and load balanced)
  4. Geographic distribution is built-in and easy to use

MongoDB stores data in flexible format JSON-like documents. This means fields can vary from document to document, and data structure can be changed over time. Instead of using tables and rows like in a relational database, MongoDB architecture consists of collections and documents. Each database contains collections, each collection contains one or more documents. Each document can be different with varying number of fields.

How does a collection differ from a table?

Instead of tables, a MongoDB database stores its data in collections. A collection holds one or more BSON documents.

Documents are similar to records or rows in a relational database table. Each document has one or more fields, fields are similar to columns in a relational database table.

MongoDB licenses – Community versus Enterprise

You need to pay for the license for business use. Copyrights of source code are with the company.

Powershell – Remoting over HTTP

By default, remoting will use WMI for communications using ports 5985 and 5986

If for some reason, you cant use WMI, say server is in DMZ. You can specify to use HTTP for remoting instead of WMI, which will use ports 80 and 443.

To use these listeners, WinRM needs to be configured to listen on ports 80 and 443 using the WinRM command or group policy. Once enabled, remoting works as normal.

How do you turn ON remoting in older machines (older than windows server 2012)?

Remoting is enabled by default on Windows 2012 and above. Older versions of windows need to have remoting enabled on the server.

On the machine which will receive commands, run Enable-PSRemoting

One could also push out the enable switch via GPO, this method can be a quick and easy way to enable remoting on all servers within the Active Directory domain.
