AWS EC2 Instance Metadata || Difference between IMDSV1 and IMDSV2 || EC2 Security || Configure IMDS

Hello Dear All, my name is Amit. I am here to give some tips and tricks about cloud learning and some day to day problem solving methods. I'm an professional cloud engineer, working in this fields for 12+ years.
If you have any queries regarding AWS issues... feel free to reach out to me.

In this video, I have discussed EC2 Instance Metadata which is, data about your Amazon EC2 instances that you can use to configure and manage your instances. It is accessible from within the instances and can be used to retrieve information such as the instance's public IP address, IAM role, and other metadata.

EC2 Instance Metadata is available in two versions, version 1 (v1) and version 2 (v2).

EC2 Instance Metadata v1 provides access to basic instance metadata and user data, but has a few limitations. It only provides data over HTTP, and the available data is limited.

EC2 Instance Metadata v2 provides a more comprehensive and secure way of accessing EC2 instance metadata. It provides the same information as v1, but also includes data on instance identity and access to the EC2 Instance Connect API. It provides data over both HTTP and HTTPS and includes improved security features such as signature verification and token-based access.

In conclusion, EC2 Instance Metadata v2 provides a more comprehensive and secure way to access EC2 instance metadata compared to v1. It is recommended to use v2 whenever possible, especially for use cases that require higher security.

Thanks for the video. I don't understand how the V2 is more secure than V1 if we can get the access key ID, secrete access key and session token on both versions? Very long details but I missed the crucial point

[DeepakShaktivel]

If generating a token is the same procedure, then anyone can generate a token and will share the information.
kindly explain me if am wrong?

In my Env all servers are using pvt network not public, Is this required to update the imdv2 and how it will be access to other users, As in your case you are using public ipv address, Please suggest on this.
