you are great man, very nicely explained. i was just revising the topics before my upcoming exam and I came across your videos and they are best. hopefully will the exam now!
Thank You very much finally after wasting 3 hour found the solution. i was using aws s3 ls and it was not working i didn't new it was taking us-east-1 as default region for s3 i thought it would take ap-south-1 based on my region but i still didn't get why aws s3 ls didn't work. I have gone through many videos and everywhere it was working in my case it was not working don't know why?
Hi.. Thank you for such a detailed video. I can't explain how much you are helping me in learning AWS. Can you explain how resource based policy differs from IAM policy?
Resource based policy is attached to a resource and it tells us that what permission are provided on a Aws resource For example on s3 -- a policy can be that user a has the access to perform read operation Identity based policy tells us what permission does the identity have over a resource Like user-a can read on s3 The point to understand here is that the only difference is in the way we attach the policies.
I guess that's something you should try, Go to ur free tier account and allow read only for s3 to a user and Try and modify the s3 policy to allow this user to both read and write. Let me know what you find.
Hello @pythoholic, want to say thank you for the wonderful vpc masterclass video. Can I get the same full video for S3. Not able to find the whole series at once
Thanks for the wonderful presentation here:). Would you mind to share the tool that you used for nice AWS Architect design diagram that you draw here!. Regards, Ra
Can you show how S3 is conected using internet Gateway through S3 default dns name?I understood that there is IAM role attached to EC2 instance but where exactly S3 default DNS name coming in picture while communicating throug Internet gateway and where is it configured?
Thanks for the wonderful video. Question: Don't I need the private DNS name for the VPC Endpoints Service (interface) if I am deploying a completely private service? The service is required to be accessible only via API Gateway.
Do all services need internet Gateway to be accessed from with in VPC ?If I create RDS or any other service withi in VPC then I think it doesn't need internet gateway
All services need a connectivity it could be either a public access using internet gateway or by using private connectivity using endpoint services. if u wish to create a private connectivity to ur rds then u have to create rds within the scope of your private subnet or using direct connect if not then we can make use of bastions.
If we need to access S3 from a private instance then I believe it can be done by configuring NAT Gateway and then private instance can connect to S3 via internet gateway?
@@Pythoholic Thank you for the prompt reply and making those excellent videos available to us. I am prepping for SAA-S02 and your excellent course is way better than most paid for ones. Many thanks, again.

ENI is private IP linked to a particular EC2 instance .What if that instace is stopped and started.WIll this ENI be changed?If yes will Elastic VPC endpoint linked to that ENI still works?
In place of S3, can we access any service thru endpoint by changing policy.....u have to explain pricing of endpoint also....if we keep ON for 24hrs, will it bill more?
Yes, you can access various AWS services through an endpoint by adjusting your service policies. AWS allows you to set up endpoints to enable direct communication between your internal network and AWS services, bypassing the public internet. Examples of services you can access via endpoints include S3, DynamoDB, and various others like API Gateway, CloudWatch, etc. Each service comes with its own set of policies you can customize to fit your needs. For instance, with an S3 bucket policy, you can specify who has access and what actions they can perform. Similarly, you can change policies for other services when accessed via an endpoint. As for pricing, AWS charges for the usage of VPC Endpoints. Pricing is based on the number of hours that the endpoint is provisioned and available, the amount of data processed, and in the case of Gateway Load Balancer endpoints, the number of hours the endpoint network interfaces are provisioned and available. So yes, if you keep a VPC Endpoint ON for 24hrs, you will be billed for those hours, regardless of whether you are actively using the service or not. The bill will also depend on the data processed through the endpoint. Therefore, it is advisable to plan and manage your AWS resources wisely to control your costs. Please note that pricing varies by region and specific AWS service, and it is subject to change. You should always check the most up-to-date pricing information on the official AWS website. For further information on the use of VPC endpoints and pricing, refer to the AWS documentation or consider consulting with AWS support or a trusted advisor.
Hello in the gateway example schema, why is the internet gateway attach to aws instead of the vpc ? Does it mean the traffi leave aws network to go to the internet. ?
In the AWS infrastructure, an Internet Gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in a VPC and the Internet. When an Internet Gateway is attached to a VPC, it enables traffic to flow between the VPC and the internet. So to answer your question, in the gateway example schema, the Internet Gateway is attached to the VPC to enable communication between instances in the VPC and the Internet. It does not mean that traffic leaves the AWS network to go to the internet. Instead, it means that the Internet Gateway acts as a gateway for traffic going from the VPC to the internet, and vice versa. In summary, the Internet Gateway is attached to the VPC to provide internet connectivity to resources within the VPC, and it does not mean that traffic leaves the AWS network to go to the internet.
Choosing a public subnet instead of a private subnet while creating a gateway endpoint can have significant implications, particularly in terms of accessibility and security. Here's a breakdown of what this choice entails:Network Accessibility:Public Subnet: A public subnet is typically associated with resources that need to be accessible from the internet. When you place a gateway endpoint in a public subnet, it may be directly reachable from the internet, depending on your network access control lists (NACLs) and security group settings.Private Subnet: A private subnet is designed for resources that should not be directly accessible from the internet. Gateway endpoints in private subnets are typically used for internal services and are accessed through private network routes.Security Implications:Public Subnet: By placing a gateway endpoint in a public subnet, you potentially expose it to a wider range of security risks, as it could be accessible from any internet location. This requires stringent security measures like strong NACLs, security groups, and potentially additional firewall protection.Private Subnet: A gateway endpoint in a private subnet is generally considered more secure, as it is not exposed to the public internet. This reduces its vulnerability to external attacks, but it still requires proper internal security measures.
@@Pythoholic Many thanks for your explanation. I was wondering what are the use cases of placing gateway endpoint in a public subnet? Is it a common implication?
Hi, In this video you have used "--region" to list the s3 bucket with VPC endpoint enabled. I couldn't get that why did you specify the region since the S3 is global service.
@@Pythoholic yeah I got your point. But my understanding, S3 is just a collections of objects in buckets. If its required to mention buckets region how can it be a global service. Correct me if I am going wrong. Anyway all the buckets rely on S3 if S3 is global then the buckets should be expected as global.
The thing here is that even if s3 is global it means the bucket name should always be unique and it can be accessed by any other accounts in any region they are. But if I have to specify the buckets of my account in the region that I have created I have to use the command with the region name. It's not mandatory but I wanted to list it for the region I have created the buckets in. That's all. But mostly even if u don't specify it will list all s3 buckets. It's the same if u do as well. I hope ur doubt is cleared. Thanks for the query
Excellent video!.. And what if you're outside the VPC (for example a VPN that has a connection to that VPC where the Endpoint PrivateLink (gateway/interface) are), how do you use the aws s3 command to access ? If you create the Endpoint Interface, some ENI's with VPC ip's are created, but when I try to use them in the "aws s3 --endpoint url 10.1.1.53 ... " command, I get this error that the hostname is not valid (of course, because the u need to use a fqdn (s3.amazonaws.com, or something similar) instead of the IP-address). So, how to fix this? I'll try a local dns hosts file change , but is there another way? or it's just not possible to use the Endpoints outside the VPC ?. I'm doing a VPN over a DX connection (due to the Public IP's for the AWS-VPN), so my OnPrem LAN has access through it to the VPC (I can SSH to VPC's VMs). Thanks
Route 53 provides Resolver endpoints and Resolver rules so that you can use the Route 53 Resolver from outside your VPC. An inbound Resolver endpoint forwards DNS queries from the on-premises network to Route 53 Resolver. An outbound Resolver endpoint forwards DNS queries from the Route 53 Resolver to the on-premises network. If you configure private DNS for the inbound Resolver endpoint, requests from your on-premises network use the interface endpoint to access Amazon S3.

Actually I don't have it as of now because it is not allowing me to upload 45 hours of content at once
Scenario - Upload all the files and directories in a drive older than a day to AWS and delete them from the drive.
How do I write a script?
write a python script to locally delete the file based on a schedule or cron job
and using boto3 upload them to s3
what is the difference between endpoint & endpoint services?
Endpoint service provides you the endpoint or the means to create an endpoint

Route 53 provides Resolver endpoints and Resolver rules so that you can use the Route 53 Resolver from outside your VPC. An inbound Resolver endpoint forwards DNS queries from the on-premises network to Route 53 Resolver. An outbound Resolver endpoint forwards DNS queries from the Route 53 Resolver to the on-premises network. If you configure private DNS for the inbound Resolver endpoint, requests from your on-premises network use the interface endpoint to access Amazon S3.
