Use your own domain name with cloud services with proper TLS certificate from Let's Encrypt

Use your own domain name with cloud services with proper TLS certificate from Let's Encrypt

As you well know, domain names are the handiest way to have an online presence. If there wasn't a way to register domain names and manage what resources they refer to, we'd all have to use IP addresses to get where we wanted to go. No typing google.com or amazon.com. Instead you'd have to remember that Google resides at 216.58.193.78 and Amazon is at 54.239.17.6.

This is where the Domain Name System (DNS) comes into play. Verisign has a good infographic on how a DNS query works. In short, DNS is a worldwide service that can resolve any registered domain name to an IP address that your browser or SSH session, for example, can route to. I will cover DNS more comprehensively in a later lesson.

Purchasing a Domain Name

Domain names can be cheap or very expensive. I suggest you search for $1 domain name on google and you are very likely run into an advertisement from companies like godaddy who offer $0.99 domains. You may want to also check other places like namecheap.com as they may also have affordable offerings. Something to note is that all domain name registrars have access to the same domain names, though naturally you may find someone has already purchased rights to the domain you're looking for. These domain name sellers are centrally controlled and managed by The Internet Corporation for Assigned Names and Numbers
