i have a very dump question to ask.. If i buy 2 domains one hosted in go daddy and another in Route 53, how its been rightly routed to the particular vendor to get the IP. Is there again a common third party who says this domain is registered in route53 and redirect the request to it??

good explanation. I have a doubt. At 8:56, when a user(browser) makes a http request to web application , how does the browser(client) know that this web application is registered with Route 53. It could have registered its domain with godaddy or with google domain or with azure dns service. How does the browser know which dns server to hookup with in the first place (before caching takes place). I guess this is related to dns propogation and all the isp dns server knows all the url to ip mapping of all the domains in the world. Can you elaborate

Hi ! I have a question, according to the Aws Documentation, they say that Route 53 operates from Edge Locations : "Additionally, you can leverage AWS services that operate from edge locations, like Amazon CloudFront and Amazon Route 53, to build comprehensive availability protection against all known infrastructure layer attacks. Using these services-which are part of the AWS Global Edge Network-can improve the DDoS resilience of your application when you serve web application traffic from edge locations distributed around the world" . So my question is, in which moment Route 53 operates from Edge locations? Could you give us a practical example? Thanks!
@Pythoholic3 жыл бұрын
The first point of contact for the users will be route53 for DNS resolution then it moves to cloudfront.

Anoter thing i read is that "Edge locations serve requests for CloudFront and Route 53 "
@Pythoholic3 жыл бұрын
Yeah it does because when ever u use a CDN it has to be resolved first with the domain controller that resides in route53 post which it's destination is determined. As you know CDN provides edge caches for the data to be cached. The access point will still remain for the Aws service that holds the data if the data is not cached.

TTL max is 2 days. Also, at 10.22 you said Response IP (URL to IP changes), isnt the resolved IP pointing to a specific resource such as ELB or cloud front serving the browser? If the IP changes next time, then wont the request fail?
@Pythoholic4 жыл бұрын
Thanks for the query, per my understanding and what i had read in the documentation it was mentioned that in a example “if i set for example a longer duration of TTL of 2 days and not exactly as max that can be set is only for 2 days” Here also i am referring to a max value of 24 hr or 1 day as and example and not that its the aws set max value. Second question: when we configure the Route 53 let suppose we have this in the scenario, so when i say URL to IP and when i say it changes then it means there can be a load balancer that sets the precedence of which instance is currently active. The DNS set at the client side is a provision by TTL set by us, and if it changes then it should reflect back to the user as well. And answering the question of failures, that is highly unlikely, but within the TTL period all the users get the cached version of the website. this was over all a simple example of TTL. At this time i hadn’t covered cloud front or ga, so it would have been confusing.

Hi , @14:19 it says ....You can create a CNAME for pythoholic.com(rootdomain) but you can't create matching record for the rootname using cname.Little confusion .Can you please explain it with example.
@Pythoholic4 жыл бұрын
So what it meant was that : We can create a CNAME record *using* with the zone apex/root domain -- let suppose zone apex is *target.com* , then we can create CNAME as *apps.target.com* or *dev.target.com* but not same as target.com itself. *Mostly as i have worked with :* A Records have been like : 10.2.11.11 CNAME : dev.domain.com ie the canonical name. that generally we as developers provide to have a meaningful name.

@Pythoholic4 жыл бұрын
@@ranjeethnadella643 So DNS resolves the IP based on mapping, let suppose we have a site www.abc.com , and internally it's balanced with load balancer, then the load balancer IP will be mapped to the Route53, so it doesn't depend on what the host has, it depends on what is mapped with Route 53, if its an elastic IP , only one IP will be returned, if there are multiple IPS, then TTL holds it for the period it is assigned. as there are multiple ways to map Route 53 to IPs. like CNAME, AAAA, A-Record etc. So yes if you have a single IP and that ip is mapped to Route 53, it will return that same IP.
