This is by far the best video I have come across on this topic! Well done, Amber! Thank you for lucidly explaining along. two questions: 1. At 13:00, if you kept hitting refresh, would it toggle the network traffic across the 2 instances in TG-2, or go to just that 1 instance? 2. How would you set this up so the network will randomly go to any of the instances across both the Target Groups? Thanks so much, Happy Holidays! 🙂

[@TinyTechnicalTutorials]

Thanks for the nice comment, @sraj7284, and Happy Holidays to you too! 🎅🎄😊 1. It would toggle the traffic across the 2 instances in TG-2. 2. I'm not aware of a way to set it up to randomly distribute traffic across Target Groups. In the rules, you have to specify the % distribution for traffic, so it would adhere to those numbers. Hope that helps! 🤓

[@sraj7284]

@@TinyTechnicalTutorials Looks like I did not ask the right question. What I really wanted to ask was, how to distribute load across different AZs, because it appears that the nodes in each AZ will send traffic to just its own target groups. Looks like there is a setting called "Cross Zone Load Balancing" that sends traffic to all AZs. Its enabled by default. You would have to go to each target group to take it out of the Cross Zone load balancing, if you didn't desire this setting. Wish you a very happy, healthy, prosperous and fulfuling 2024 ahead! 🙂

[@praveensequeira1525]

Hi, smooth as always, thank you! My questions for you: 1) If we add route 53 to the mix (referring to your video), will the DNS get resolved to the ip address of the load balancer or the actual instance that processed the incoming request? 2) My understanding is that we created the ALB nodes in multiple AZs - is this optional and for HA and fault-tolerance reasons. Or we could also choose to create a singular ALB node instance (in one of the AZs where our TGs/instances are running)? 3) If we chose to create ALBs (node) in multiple AZs, will the incoming traffic gets distributed to ALL of nodes (based on some algorithm) or is it only ONE node that still receives all the traffic and does the distribution to the TGs?

[@TinyTechnicalTutorials]

Hi Praveen! I haven't forgotten about this one! 😊 1) If you add Route 53, you'll want to create an "A" record/alias that points to the load balancer. While in theory you could point it to a specific instance if you knew the IP, the point of having a load balancer is so that IT can route traffic to the instances, it can do health checks, etc. (you can also set up an SSL certificate, use WAF on it, etc.). So pointing to the load balancer is the way to go. 2 & 3) For the application load balancer specifically (vs. network load balancer or classic load balancer), you're required to choose at least 2 AZs. There's a pretty good description/diagram here about how routing works across AZs: docs.aws.amazon.com/elasticloadbalancing/latest/userguide/how-elastic-load-balancing-works.html Hope that helps!

[@DM-ky4jw]

Hi, can we configure multiple target groups(different lambdas) in a single ALB and route traffic to secondary region for the failed target groups only

[@TinyTechnicalTutorials]

Hi DM! 😊 Load balancers are region-specific, so it's not possible to route to a second region with *just* a load balancer. To go cross-region, you'll need to use Route 53 (which is a global service, and can therefore route across different regions). Here's some more information: docs.aws.amazon.com/whitepapers/latest/real-time-communication-on-aws/cross-region-dns-based-load-balancing-and-failover.html

Do security groups still hang around after deleting the instance using it?

[@TinyTechnicalTutorials]

Ooh, good question! 🤓 Yes, they'll persist even after deleting the instance. You can have multiple instances using the same security group. So if Instance A and B were both using the same security group, you wouldn't it to be deleted if one of the instances was deleted.

Is it possible to create one ALB for all services? I mean using Wildcard ALB with certificate for every services?

[@TinyTechnicalTutorials]

Hi Ali! 👋 It's technically possible to do this, but could make it more difficult to identify and troubleshoot if there are issues. And obviously there would be a single point of failure. There are some good points here in this thread to consider as well: stackoverflow.com/questions/65447698/aws-alb-single-for-all-services. Hope that helps! 😊

@@TinyTechnicalTutorials Thank you very much for taking my question into consideration! I've checked the link you provided and I also want to extend my gratitude to them for sharing their ideas. I agree with you regarding the concern about a single point of failure. However, I also need to consider the trade-off between costs and complexity, as is often the case. Regardless, I greatly appreciate your videos and have learned a lot from them!

[@alishirdelan9488]

@@TinyTechnicalTutorials ‌Hello Amber, another question comes up: Consider this: I would like to use a single set of EC2 instances and assign them to two or more target groups for utilization across two or three ALBs. Each ALB would have its corresponding target group, as these instances are meant to be allocated to two or three different target groups. This setup ensures redundancy: if one of the ALBs becomes unavailable, the others can continue functioning. Furthermore, all EC2 instances should remain reachable. Is this scenario reasonable, or are there drawbacks to consider? Given that DNS (Route 53) is internet-facing and the ALBs must be positioned behind other ALBs, the question arises of which services or load balancers should be interposed between the ALBs and DNS. Is it advisable to use wildcard DNS? In this context, the query remains: How can incoming traffic from external sources navigate through DNS and then be accurately directed to the correct ALB with its associated target groups?
