The AWS learning challenge continues. This week was about Route53 which is literally the first time I touch this service and then some deeper dive into VPCs. Route53 gives a lot of flexibility and customisation but it is quite expensive for buying new domains and also you have to pay to transfer your domain which was a bummer. Nevertheless I gave it a try and it now makes a lot of sense.
Afterwards, in the VPC section there were some a bit advanced topic which I have to admit are difficult to make sense in a tweet. One of the biggest advantages I have seen so far is that it is a lot easier to follow devops related conversations and understand why certain decisions were made. Enough with me blabbing let’s go to the content.
Let’s talk about AWS Route53
It is a managed DNS (Domain Name System) service which contains a collection of rules and records for reaching a server through its domain name
The most common records include
Let’s do a comparison of when to use CNAME vs Alias in AWS Route53
AWS resources expose a hostname that looks like
http://abc-123.eu-west-2.elb.amazonaws.com. You want that to point to http://yoursite.example.com
The CNAME points a hostname to another hostname. Only for non root domains
