How to Setup Nodejs Mongodb in Production server on Ubuntu 18.04 in AWS, GCP, Azure, Digital Ocean Cloud Instance or Locally

Talking of DevOps practices like infrastructure automation,there are lots of great tools out there for large enterprise applications. However, for small applications, it would be an overkill like using a sledge hammer for a fly. So why would I use Infrastructure as Code System such as Terraform, or Configuration Management System Chef, Ansible, Puppet; when I can simply fly with this 5mins installation guide 😜 (just kidding, I am learning them πŸ“š)

I regularly update the installation steps so get the Github gist for the most recent.

# Steps to write and execute a script
# Open the terminal. Go to the directory where you want to create your script.
# Create a file with . sh extension.
# Write the script in the file using an editor.
# Make the script executable with command chmod +x <fileName>.
# Run the script using ./<fileName>.
