Recently got introduced to Your channel n am enjoying learning .. complex concept explained with simplicity 👏🏻👏🏻.. keep making such videos !! Thank you 🙏🏻

[@knowledgeindia]

Thank you. You can share it with your circle and help more people to learn easily

[@pranaytonpay1246]

why did it take me so long to reach this channel ? the videos are awesome !!!!

[@knowledgeindia]

Glad it helped you.. You can share our channel on LinkedIn/Facebook to let others learn from out tutorials as well.

[@pranaytonpay1246]

Sure,,, are they any videos that talk about API gateways ? i could not find any

[@Gionawii]

How is Instances live in a private subnet get internet from the ELB even if the instances in the private subnet do no have ip address. Isn't the instances in the private subnet are registered to the ELB and the ELB uses its private ip?

[@getevivek]

Any reason why NAT Gateway have to be placed in the Public subnet? Can it also be placed in the Private subnet?

[@knowledgeindia]

no. Because NAT Gateway should be able to to talk to Internet directly using its Public IP. please check out our playlists for more -- kzbin.infoplaylists

[@mangeshjoshi8875]

Very well explained, really appreciated

[@jonathanchan564]

Thanks for such a great explanation!

[@knowledgeindia]

I am glad it was helpful. There is more on our channel, please check the AWS playlists on our channel.

[@bhushanamrajendraprasad9821]

Hi, I have doubt, you have mentioned in video, In private subnet created the ec2 instances in A.Z 1, will same ec2 instances in A.Z 1 will automatically reflected in A.Z 2 in private subnet for High availablity ?

[@ravi20670]

Here traffic generated from internet goes through ELB where it distributes to the web server placed in private network. once it gets the requested input from webserver will it go through ELB again ??? As explained here local ips in private subet need to have NAT placed in public subnet when they want to access internet or any outbound traffic.

[@knowledgeindia]

for the first thing, yes the reply goes back via ELB. NAT would come into picture when traffic is initiated by private instances e.g. Access a third party AP.

[@knowledgeindia]

e.g. Accessing a third party API

[@srinivasan3078]

Nice one with crisp explanation for easy understanding.Am also interested to know any videos for IAM & AD Am a starter in AWS and crawling in learning and videos are useful too , Keep up this good work !

[@akash532]

Sir, you make it really easy with your explanation, thanks for the wonderful knowledge share !!!

[@knowledgeindia]

Thanks Akash. You can support us by sharing our AWS videos with your friends / colleagues.

[@farwanqv]

I am clear about auto-scaling and ELB. However ELB is a seperate service in AWS where as Auto-Scaling is an option within EC2 service. How are both of them different i.e. Auto-Sclaing within EC2 and ELB as seperate service? I understood that Auto-Scaling is achieved by creating Auto-Scaling Groups and Launch Configuration. But that is not enough unless we create load and associat Auto-Scaling Groups+ Launch Configuration to ELB. However I always get confuse when I am trying to answer MCQ's for exams that focus on Auto-Scaling as feature etc.

[@knowledgeindia]

Its simple. ELB is there to distribute traffic/load to n number of instances. Auto scaling group is there to keep the desired number of instances in running state; and also increase or decrease the number of instances, based on the need. Check our Auto scaling video and ELB playlist..

[@farwanqv]

@@knowledgeindia Thanks so ELB is an AWS service and Auto-Scaling is a feature.

[@mishrahimanshu12]

Just a feedback - at 5:00 you say "even when they don't have private IP" I think it should be public IP?

[@knowledgeindia]

That's right. I have updated in the description now.

[@bhavyasreethakur6634]

Thank you Sir But have a doubt related to this.. You said Nat Gateway can’t span AZ’s , but from the diagram show in this video, Request from instances in other AZ’s also directing to NAT. Will this serve the purpose in Real time or need Another NAT in other AZ ??

[@knowledgeindia]

Serving traffic from another az is one thing, but it exists in only one az and hence if that az goes down there would be a problem ..

[@ssapre65]

Thank you for crisp and easy to understand explanation.

[@akshaygupta8723]

Great Video. You mentioned having 1 NAT per AZ for HA. But how will my private EC2 traffic route to the second NAT incase one goes down. Is there any config we need to do?

[@knowledgeindia]

You will have to put 2 Route tables for 2 different private subnets and in that point to 2 different NAT gateways. Please support us by SHARING our videos. Thank you.

[@SwatiMishra-nw8td]

If the ELB is placed in the private subnet, how then the internet traffic is routed to the ELB?

[@knowledgeindia]

Hi Swati, If you place ELB in private subnet it won't be reachable from internet. We normally keep ELB in private for the internal purposes e.g. ELB between Web and App tier (in 3 tier architecture). If you want to keep ELB in front of Web tier, it should be there in Public subnet only -- kzbin.info/www/bejne/qqm3gaWDatWlpbM Please let me know if it is not clear still. Here is the link for live streaming event on coming Saturday (9PM IST) --- kzbin.info/www/bejne/Z2nVeH5onKp_fKM Hoping to solve some of your questions on AWS.

[@SwatiMishra-nw8td]

Thanks, I got your point. Thanks for the link, looking forward to it. Also, it will be really helpful if you could discuss about cloudformation service in detail, brief about template designing etc. Thanks.

[@knowledgeindia]

Thanks Swati. Have you watched this video already - kzbin.info/www/bejne/rnSoY6alrNegj5I Please let me know some of your doubts or things which are not clear on CloudFormation.

[@SwatiMishra-nw8td]

Sorry, I didn't. I'll watch it straight away. :) I came across your channel only recently. Have been glued to my computer since then. You have some pretty great videos. I'll definitely watch them all and share with my friends and colleagues. Thanks for all your help and keep up the great work.

Nicely Explained. :)

[@venkatesh9290]

Hi Sir what is the difference between NAT and NAT instance.

[@knowledgeindia]

NAT is concept. could be achieved using NAT instance or NAT gateway. Differences are given on AWS website and some of my videos as well.

Good explanation. Have been watching your videos...We'd request you how to prepare resume for freshers as a solution architect, a good example of demo resume.

[@knowledgeindia]

i will try

[@glibmar]

NAT is very expensive. Make sure that you really need it before using. You need to use VPC Endpoint service if you need to have access to AWS services (S3 for example)
