This will be a documentation of moving a website from GoDaddy shared hosting to Digital Ocean droplet.  Any other cloud hosting service should work with variation in the server creation on the cloud system.  For example other services such as Linode etc.  Note that Digital Ocean calls their virtual machines droplets, other providers will have a different name.

While documenting this process I moved the domain 09flhrc.com from GoDaddy shared hosting to a Digital Ocean Droplet. The IP address assigned to the droplet is 143.110.204.149

The Linux kernel includes the Netfilter subsystem, which is used to manipulate or decide the fate of network traffic headed into or through your server. All modern Linux firewall solutions use this system for packet filtering.

The kernel’s packet filtering system would be of little use to administrators without a userspace interface to manage it. This is the purpose of the **iptables** utility: when a packet reaches your server, it will be handed off to the Netfilter subsystem for acceptance, manipulation, or rejection based on the rules supplied to it from the userspace (via iptables). Thus, iptables is all you need to manage your firewall, if you’re familiar with it, but many are available to simplify the task. We’ll take a look at the default frontend used in Ubuntu here.
