[@gauravchoudhary3733]

I don't know why this channel has only 22+ K subscribers. This channel is one of the best in its class and Very crystal and clear explanation of each and every concepts, even for a single abbreviation as well. Rahul is a true AWS Community Builder. Kudos Rahul for all your efforts and covering/explaining some of the most useful and critical services of AWS.

[@RahulWagh]

Thanks for your kind words 😊

One of the best training channels. Great job Rahul. You are a trainer with great in depth knowledge. You are a master.

[@shaiksaif4982]

Thank you so much for detailed explaination and Steps for launching Application load balancers for EC2 with VPC and internet gateway this video helped me alot while doing my project.

[@RahulWagh]

You are most welcome

[@Anand-pb3nz]

i am still not able to understand why there are only around 37K subscribers. Too good Rahul. Keep going dude. Such a perfect and clear instructions.

[@RahulWagh]

Glad it helped!

[@deevelarajesh7872]

Really liked it. Everyone can easily understand the concept. Especially for beginners this tutorial is very useful👌👏

[@RahulWagh]

Glad to hear that

[@ShaikshaVali-wb9ko]

Super explanation sir..doing great work..

[@niroshthota5819]

Thanks again in detail, one Question, Can You please share if you written steps for all whenever we get time we can look into that so that it will make easy for us and not to forget

[@trishul_bawankar]

Every chapter has been made so easy to understand! :)

[@RahulWagh]

Thanks for stopping by on my channel and stay tuned there are more to come

[@dayanandthorat4213]

This content cleared my concept of ALB !!!! thank you so much for taking efforts making such content 🤩

[@songbaiyin7830]

Thanks for your sharing, it's concise and to the point. One thing about this one, per my understanding, the default security group associated with ALB could be removed becoz we have created our own one.

[@karthik.karunanithi]

Super tutorial, very good

[@RahulWagh]

Thank you! Cheers!

[@thapasujan07]

Beautifully executed Sir. ❤

[@RahulWagh]

Keep watching

[@theophilus4723]

Thanks

[@RahulWagh]

You made my day

[@dnyaneshwarmuley]

Thank you Rahul, it would be great if you could also share the purpose behind creating vpc, internet gateway , subnet etc

[@RahulWagh]

The reason is it’s not advisable to work in the default vpc, default subnet, you must always work within your own vpc otherwise it becomes messy and hard to manage resources

[@ashishpandey8766]

Thanks Rahul

[@RahulWagh]

You are welcome

[@bhardwaj_abhi3421]

Nice Explanation . You have mentioned terraform, helm chart etc at the end of video .. can you tell me where they are used in software development and what is advantage of learning them

[@AmarinderSandhu-sr3ij]

Thank you for the awesome explanation. I really appreciate your work.

[@RahulWagh]

Glad it was helpful!

[@Shrikanth134]

Thanks for the video. I am still starting with AWS, i had this question - it seemed like ALB implicitly took care of routing traffic from users to the target groups. Was there a need to explicitly define route tables and attach it to igw ? Wouldn't the setup have worked even without the route table ?

[@nirmesh44]

Best. explanation ever. great work.

[@RahulWagh]

You are welcome

[@cloudwithjd4068]

Hello Rahul I really impressed with your video and explanation. When I’m create on my EC2 instance . I’m able to install the Apache but I’m not able to print the EC2 instance hostname. When you have some free time can you share it with me the user data script which you used while creating the EC2 instance . Thank you Jagadeesh

[@godmoneyhateandlove9315]

Wonderful guy

[@sanketkale6384]

in video at time duration 17.32 you said we created public and private subnet but we have created public only.

[@shiv0096]

In alb some issues, instance can't reach the site , through public address

[@praveenagrahari4207]

Thank you so so much ....

[@RahulWagh]

You're most welcome

[@ShaikshaVali-wb9ko]

Hi sir..in my windows 10 lenevo laptop cant install putty and puttygen.. please help me..

[@ravikishore-cg9er]

17:23 you just said private subnet bro i think its public-subnet

[@mayankrawat5149]

Which script we have to copy in user data plz reply

[@sruthi2016]

Can you please share the same concepts using Terraform Example: how to serve an ec2 instance in a load balancer aws using terraform

[@RahulWagh]

It is progress but those session will be exclusive for youtube members of this channel. If you are interested then you can also join it - kzbin.info/door/7p4oXcPbgk_yTSHK7QlkSgjoin Hopefully in future i will make it available on youtube for everyone

[@ChandanKumar-xd1tg]

please make a video microservice two target group create

[@RahulWagh]

Thanks but didn’t understood your comment?

[@spartenmadhan141]

Hi Rahul, I have a doubt for one web application we are bundling the instance in target group and bind it to ALB. Then using ALB DNS link to access them. Lets say i have another similar instance in that case i have to create another ALB and do same steps?

[@smmrok]

I think VPC and more are better options which create subnet/RT/IG for you automatically

[@RahulWagh]

I couldn’t get your comment are you suggesting the default vpc creation where you get IG/subnet etc created for you instead of creating it manually?

[@smmrok]

@@RahulWagh - No ----- You created manually one VPC and Subnet/RT/IGW - you did all those after VPC creation- Instead if you select the (VPC and More) option when creating your own VPC then you can avoid all those manual steps- AWS will create all those secondary legs(subnet/RT/IGW..) attached to VPC for you in one shot -

[@yaseenbaba3389]

Excellent! Can we achieve the same using Terraform

[@RahulWagh]

Yes you can. Here is link of my another session where i have show how to do that - kzbin.info/www/bejne/paW0opdtfLeJgZI

[@ShreyaSingh-so6jg]

Hi Rahul, Why are we using default security group here along with the security group which we made for http request. I automated this project using terraform and everything worked well except the part where i had to include default security group in my target group. Without that my instances were in unhealthy state. Post applying the default sg, it worked smoothly. Please explain. Thanks, Shreya

[@RahulWagh]

The default security group in AWS is automatically created in each Amazon Virtual Private Cloud (VPC). Its purpose is to provide a baseline level of security by allowing all outbound traffic and denying all inbound traffic initially. It serves as a starting point, and users can modify its rules to meet specific requirements. The default security group ensures instances can communicate with each other within the same security group while restricting unauthorized access from external sources.

[@bharathraj8467]

I have one question, will we get the result if we use the linux instance in ec2.

[@RahulWagh]

I didn’t get your question

[@Shail786]

Hi Rahul, I am doing an AWS WAR activity for my company AWS account through AWS Partner. For security purpose Partner created Private VPC for server migration so that we can securely access the server through vpn only. After migrated the server from public to private, have created application load balancer in private vpc with single server only instead of 2 servers. Everything is properly created as required but my website is frequently giving 504 gateway timeout and sometimes 502 Bad Gateway error. So, can you please help me, what is wrong in my setup and why getting these errors?

[@user-lb1ed5jw4u]

lets say i'm hosting a website on aws and i used load balancer on my backend ec2 instance, as I have only 1 instance then how will the load-balancer handle it, it should run more instance of my backend server, but in your video it isn't happening

[@RahulWagh]

you need to create target group and then you can add either 1 ec2 or more than 1 ec2 instance. After that you can point load balancer to target group. There is no direct connection between loadbalancer and target group.

[@shubhamnikam1238]

Suppose I have a cluster with 2 instances on one I am running MySQL image and on one I am running spring boot API I have linked API with db. So while creating a target group do I need to add both db and API in one target group

[@RahulWagh]

No you do not need to add MySQL db into the target group

[@shubhamnikam1238]

@@RahulWagh I did create TG and added only API instance to the tg and then created load balancer. but tg is unhealthy with 401

[@RahulWagh]

@shubhamnikam1238 check the health endpoint of TG and ec2 health

[@shubhamnikam1238]

Here i already start the cluster and both db and API instance are running and afterwords I created TG and LB

[@pavanjoshi1]

can not we forward the request to private subnet?

[@hrushikeshborse]

for me-health checks are failing for the private instances while they are successful for the public ones

[@surajmane9090]

Application load balance is only for Public Subnet ? and why is not foe private subnet

[@RahulWagh]

Although in my session I showed it from the public subnet but you can configure it from the private subnet as well

[@ShaikshaVali-wb9ko]

Super explanation sir..doing great work..
