AWS VPC Security Group Naming Convention

Does anyone see any potential issues with this naming convention for EC2 security groups?

Security Group Name - EU-P-LWA001
AWS Region ( 2 char ) = EU, VA, CA etc
Environment Code (1 Char)  = P-Production , Q-QA, T-testing, D-Development etc
OS Type (1 Char)= L -Linux, W-Windows etc
Tier (1 Char)= W-Web, A-App, C-Cache, D-DB etc
Application Code ( 4 Chars) = A001

Does this help to solve the logical separation by service? For instance, logstash server vs. elasticsearch server?

Security groups can also have tags, which you can use as filters. See e.g. http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-security-groups.html

tag-key - The key of a tag assigned to the security group. tag-value - The value of a tag assigned to the security group.

You might have a more functional system if you use these tags in addition to your cryptic names, because then there will be a standard syntax that you can use to filter for groups that have specific properties - including perhaps properties not yet anticipated in your naming scheme.
