Exercise: Writing an Inventory

Task

You need to come up with a hosts file (INI format) for an infrastructure project of a tech startup that needs to manage its IT infrastructure, with specific needs as listed below:

• A cluster of three database servers.
• A cluster of three load balancers.
• Two servers for managing caching services.
• Two servers for managing the messaging queue.
• Two web servers running Apache and one web server running NGINX.
• One server for monitoring and insight.
• One server for critical backups.

Based on these requirements, devise a suitable inventory for the project.

Note: Please include the relevant connection parameters for each host, like the username and the password. Also, assign the IP addresses in a sequential manner.
