How do I find the current versions of the AWS services that I am consuming as an organization

Hi,

I think that AWS Config is what you want: https://aws.amazon.com/config/

AWS Config is a fully managed service that provides you with resource inventory, configuration 
history, and configuration change notifications to use security and governance. With AWS Config, 
you can discover existing AWS resources, record configurations for third-party resources, export a 
complete inventory of your resources with all configuration details, and determine how a resource 
was configured at any point in time. These capabilities use compliance auditing, security analysis, 
resource change tracking, and troubleshooting.

The above is first question in FAQ: https://aws.amazon.com/config/faqs/

Best,

Didier
