AWS architecture diagram

1. If you have a CloudFormation template, then you can load that up in the CloudFormation Console and click on 'View in Designer' on the home page, which will provide you the architecture, and the relationship between each resources as per your CF template. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/working-with-templates-cfn-designer.html
2. For viewing the processor details, you can either do via the console or CLI. If via the console, then go to the EC2 console, by searching for EC2 in the AWS management console, and then click on instances, which should list all your instances in the region. Click on preferences and make sure you have selected the 'Instance Type'. This should give you the details of the instance type which you can use to derive the vCPU's, cores etc. If you are doing it via CLI, then use $ aws ec2 describe-instances and this must list all your instances along with instance types. Use the instance type against https://aws.amazon.com/ec2/instance-types/ to validate the details

No, it's not possible to create a diagram of your architecture in one click. However, there are various tools and services that can help you create architecture diagrams, such as AWS CloudFormation Designer, Lucidchart, and Draw.io.

To get the full description of an instance, you can use the AWS CLI or AWS Management Console. In the AWS Management Console, go to the EC2 Dashboard, select the instance you want to view, and click on the "Description" tab to see details such as instance type, vCPU, memory, and storage.
