Very useful thank you. It was helpful seeing how to verify by checking the route table after creating and seeing the example of successfully accessing the S3 bucket.

Thanks Nice explanation. I have one question. Suppose I have deployed my rest api in EC2 instance is running in private subnet and it is developed in ruby rails. Will API Private gateway will work? How Can I integrate with my Rest api server to API Gateway?
thanks for the clear explanation. liked and subscribed! had a question, from the private ec2 instance 10.100.1.6, when you did a wget to the S3 URL, it was not accessible because there is no route to the internet .. but how was it able to resolve the S3 URL to the public ip of 52.219.64.45? confused .. DNS should also not resolve correct? or was it cached from earlier maybe? thanks!
That’s interesting question. Basically AWS runs the Private DNS resolvers at VPC +2 IP address which will be 10.100.0.2 in your case. There is also a virtual IP 169.254.169.253 (if I am not wrong) for the same. All DNS resolutions happen using this DNS resolver. So it can still resolve the Public IPs of AWS services via this DNS resolver.
@@AWSwithChetan thanks a lot for the response. So DNS resolution for public DNS hostnames does not require internet access (via IGW or NAT?)? Sorry if the question is silly, i was still confused .. if you could tell me the flow of the resolution .. meaning, the query from the private ec2 instance travels to the VPC resolver at 10.100.0.2/169.254.169.253? .. from there..? thanks!!
@@bhakta_rg That's really a good question infact. Thanks for asking. Yes the Private EC2 instance can resolve the Public DNS. It does not need IGW or NAT. This is donw using Route53 DNS resolver which runs at VPC + 2 IP address.
What happened if we enable the vpc endpoint for public subnet and acess the s3 bucket 🪣, is the traffic still inside the AWS? Or the traffic will go outside to the internet?
If you have VPC gateway endpoint enabled for the subnet and subnet route table has a route then of course it will go over the VPC endpoint as that route will be more specific (longest prefix match) than the internet route.
@AWSTrainingCenter thanks very great question and answer I was having confusion with. One question what's those IPs in route table which got updated automatically on association ? Are these IPs constant for S3 ? Also security groups should be updated as well right ? Maybe in this example we don't have any on ec2 as well as endpoint ? I was thinking it's mandatory for vpce to have sg
AWS Training Center There is neither default route to IGW nor any route to NAT GW, NAT GW doesn't even exist. When I create VPN endpoint and attach to my custom VPC and associate my Private SN then only S3 access should work i mean my Bucket Access but yum commands like yum update, yum install httpd/vsftpd are also working but ping google.com or curl google.com are not working.
@@AWSwithChetan Sir, I may be somewhere wrong but have done this practice 4 times, also ping or curl google.com is not working but yum commands are working.
rajendrasati Your S3 bucket is private by default and no one can access any data. For vpc endpoint to access data you have to add corresponding permissions in the s3 bucket policy. If buckets are Public then its anyways accessible to everyone.
Sorry about that, google doesn’t pick my accent (blame me for that) so would have to generate captions manually. On my to-do list now! Thanks for bringing this up to me.
I have a comment for you. I was blind in AWS world and you have made clear all the concepts. Thanks , now learning like maid
Very useful thank you. It was helpful seeing how to verify by checking the route table after creating and seeing the example of successfully accessing the S3 bucket.
Crisp and to the point with a nice demo
This is a perfect and to-the-point video. Thanks so much. Subscribed to your channel.
Direct to the point. This is awesome Bro.
Appreciate it!
Super and Clear explanation. now i understood the concepts of Endpoint.
Nice and Very clear Explanation. Thank you bro....
many thansk for your explanation, one question which case of endpoint is it? interface endpoint or gateway endpoint
From VPC to S3, use Gateway endpoint. It doesn’t have additional cost.
@@chetanagrawal492 MAnY THANKS for your quick answer :)
Thanks for uploading. This was helpful.
Excellent video ! Thank you very much !
Very nice! Clear and concise!

what is sg of private subnet EC2 instance apart from SSH
awsome sir,please make more vedios
Thanks a lot sir. Very much informative.. Good job.
Thanks. Very clear
Excellent. thank you.

Could you please tell how security group of ec2 looks here ? How is it working without permitting all traffic having sg of vpc endpoint as source ?
Yes, same worked. but, Why yum commands work, we are only giving access to S3 only ?
yum should not work. Check if you are trying from private ec2 instance and subnet is really private with no route to igw

This is not possible Yashpal. Please verify step by step.

It is true. I have also tried it.
Thank you too much..very informative
nice hands-on video.
What is the security here? Anybody can create endpoint and access your S3? Isn't it any check where you approve any endpoint request?
rajendrasati
Your S3 bucket is private by default and no one can access any data. For vpc endpoint to access data you have to add corresponding permissions in the s3 bucket policy.
If buckets are Public then its anyways accessible to everyone.
Thanks a lot..
Why disable cc? Very awkward... couldn't watch video...
