Mastering AWS Network Load Balancer | ALB vs NLB | Step by Step Tutorial - Part 18

[@SrinivasD-tr6eh]

Hello Rahul, I don't know how you have this much patience to explain everything in every video. This is the best channel I have seen in KZbin till date for AWS. Thank you for your efforts...!!!

[@Learn_IT_with_Azizul]

ALB VS NLB contents are very rare… thank you very much! Also, have a request to have another content on OpenShift in-depth hands on using AWS cloud. 🙏

[@RahulWagh]

Thanks let’s see how much time I get

[@efuchsman]

You are the man! Thank you so much for all of these videos!

[@RahulWagh]

Glad you like them!

[@fintech1017]

I appreciate the video, it helps with the overall understanding of the LBs in general. Couple of feedback that I would like to share: 1) Internet Gateways are VPC specific and not subnet specific so, possibly it will make more sense to attach it to the VPC rather then the Subnet. 2 ) Why not use Auto scaling group as it will help in a complete architecure set up and a good point of using LBs as well. Other than that, I really enjoy the video! Keep up the good work! Thanks

[@RahulWagh]

Thanks for the feedback i truly appreciate it.

27:14 - I was expecting after you chose TCP instead of HTTPS that the port to the right of the dropdown change: - from value: 80 (which is standard for HTTPS which was initially shown as pre-selected option in the dropdown) - to value: 443 (which is standard for TCP) Isn't that what should have happend? Also, you mentioned "" . So why is it that at 27:23 health check remains on HTTPS... and how come this didn't give any errors subsequently? I tried answering these questions on my own and I came up with: TCP & HTTPS are actually not "antonyms" let s call them. Actually TCP operates at layer 4 in the OSI ISO model and HTTPS operates at layer 7. Also HTTPS operates on top of TCP. Basically: when you access a website, your browser uses HTTP (Layer 7) to request web pages. HTTP uses TCP (Layer 4) to ensure the data is transmitted reliably. Also at 34:31 port 80 actually now shows up as port 81... was that something automatically done by AWS? other observations / questions: - 35:15 Application* Load Balancer just to make it crystal clear - 37:11 in other words: we are simulating our application has multiple responsibilities; and you are showing us how we can leverage ALB to basically separate these different responsibilities (2 responsibilities in our case) of our application across different endpoints (in our case they are actually different machines!!) of ours. Nice! - 45:55 why is weight 1 okay? Shouldn't we route 100% of requests whose ending path end in "foo" to that "foo-tg-alb" target group?

hi Rahul, i setup two EC2 webservers inside Private Subnets, then create NLB, but health check always fails. There is no NAT gateway for Private Subnet. Could you please point me to the right direction?

Hello. If u want to achieve the same thing with nlb, how will we do it?

ek hi machine bnaoge agar.... toh kya load balance kroge ??? target group bnadiye foo and bar ke ek hi machine par.... toh load balancer ka kya role rehgya esme ?? or ek yeh bhi ni btyaya ke ec2 ke ip ke sath bhi access ho rahi h website only load balancer se honi chahiye...... adhuri knowledge hai....

[@punkygamer7668]

This will be great for the modern applications which doesnot directly run Database server inside the same EC2 instance. But what if im using the database mysql server inside the same ec2 instance and it would be very difficult to keep both ec2 instance data updated as seperation of database is the only way to achieve this functionality. can you clear me more.

[@RahulWagh]

You should never use the mysql database and ec2 instance in the same server always go with separate ec2 and mysql database

[@sainathmandavilli6538]

correction: Internet gateway is supposed be on the vpc level in the diagram.

I will it into my list

[@fadi07full]

we are hosting a web scraping API on ECS EC2 mode and we want the scaling to be horizontal... in this scenario we should use ALB or NLB in front of ECS? as we need different ips to avoid ban.. but we faced header size restrictions in the ALB so far for some APis..

[@RahulWagh]

Go with NLB bcz it has higher throughput compared to ALB and you will not have problem of header restriction

[@kmadanofficial]

Excellent… can u please let me know how you are creating those architectural diagrams

[@RahulWagh]

I use power point to create the diagram

[@kmadanofficial]

@@RahulWagh in power point i dont find Aws related icons or designs

@@RahulWagh along with vedios...can you pls share the ppt also which you showed in the vedio

[@Giridhar_KS]

In my case, bar is working and foo is saying not found.. Could this be because bar TG is selected as the default in the ALB ??

hi rahul bro. If we use s3 for remote statefile, can we delete state file through same terraform code as well as s3 bucket. Not manually

In every lab why are you creating vpc

[@RahulWagh]

Because a lot of viewers does not watch the complete series they just directly jump to the topics in which they are interested, so if i do not show the VPC creation then there is no point in explaining the actual concept because VPC, Subnet are the backbone of the networking. I know it is annoying for the regular user who follow the the complete series but if you can directly refer to the timestamp(see description section) if you feel it boring and you know the vpc setup already
