AmazonEC2RoleforSSM - This policy will soon be deprecated. Please use AmazonSSMManagedInstanceCore policy to enable AWS Systems Manager service core functionality on EC2 instances.
If EC2 instances are not exposed to internet and want to redirect them to look into S3 buckets which are publicly exposed, how can we do it? Created and attached IAM policy to the role but didn't help.
Patch manager adds more features such as patching many instances at the same time and ability to schedule patch operations to run during a maintenance window
