You’re forgetting in the explanation that a domain can have multiple A records so if one server of the IP pool is down, the traffic will go to the second A record. And in some cases, banks use www# instance, it’s because of the service type for not mixing systems, for example www2 is for personal banking system, www3 is for enterprise banking system and so on.

@@tripplefives1402 this isnt really true load balancing but rather a round robin rotation of the entries. there are global load balancers that utilize DNS and act as a nameserver but this is for very large global environments. As for taking hours to days this isnt entirely accurate either. DNS zones are configured with a TTL or time to live. Most places doing global load balancing will have extremely short or the load balancer will manage the TTL intelligently. I have a large knowledge of DNS as I was a DNS admin.

@@tripplefives1402 incorrect I was actually referencing GSLB via F5 GTM Load balancing. GTM uses a delegated DNS zone to modify DNS entries depending on backend web servers, for example GTM in western US goes down a GTM in eastern US will take over. it is way more effective and intelligent. DNS round robin doesnt know if a site is completely dead so if a webserver isnt responding DNS will still happily reply with its address because it was told to do so.
@NillKitty3 жыл бұрын
@@DeadlyDragon_ GSLB is not just for "very large global environments". It's used any time you want to load balance without the traffic going through the load balancer. It's absolutely required for some things that cannot be proxied or NAT'ed easily, traffic that is destined for different datacenters, or load balancing of things based on other types of records (e.g. MX records mapping to a series of mail servers). GSLB is just "DNS with smarts". There are cases where you might use GSLB even if you're not load balancing, and you just want the DNS response to be subject to health checks/server availability.

Some load-balancers support "sticky sessions" and always redirect the same user/context to the same server. Perhaps www1,2,3 is an old-school easier way to make sure each subsequent request stays on the same server.
@mihiguy Жыл бұрын
not necessarily oldschool, when your website/webapp is hosted at multiple sites and you try to route your session to the fastest server - DNS does not in general do this well if you need sticky sessions even if the user changes network (e.g. wifi to mobile) which may change location-based DNS results. You can work around this on the server, but why do you need to hide it? If you use sticky sessions, the session ID will in any case have some "worker ID" embedded, so technical people can always find out whether their session is on the same server or not.

Few things that are a little wonky in this: • The misspelt domain is an ad domain so not really owned by the true company. • A records can be used to load balanced, either by having multiple entries, changing responses (using something like AWS’ Route5) and an IP can go to multiple servers/data centres. This is how services like Cloudflare DNS and Google DNS (shown as example IPs in the video) work. Any cast IP systems allow for this hence how you can always use 1.1.1.1 for CF, though they are not a default option a lot of the time and tend to be used by large enterprises/infrastructure systems.

It’s a completely optional subdomain that *was* a common convention but nowadays is mostly only used so that people who stubbornly type it in don’t receive an error page. And it’s not the browser doing the redirect, it’s the server. The load balancing can also happen at the IP level (the actual server exposed through an IP address can change).

A bit of clarity, backup and load balancing are different practises, load balancing a group of servers share the work through some rerouting, and backup servers pick up the load when a primary server is unavailable. I suspect backup servers are less frequent now on large systems, load balancing sorting out fail over. But a large project may not want to roll out updates to all their servers at once, exposing them to loss of service if there are any problems.
