Hi,

I know about user data, which will be provided by the user at the time of booting instance in order to excute script and change host name etc.

I have few questions about metadata? 1. who will provide the metadata? 2. AFAIK metadata is instance specific data that means is VM ram, vcpu, harddisk etc? is it correct and if wrong please correct me what is instance specific data? 3. what is the use case for metadata?
