 ### VPC and Network Security Gotchas and Limitations
 
--	🔸Security groups are not shared across data centers, so if you have infrastructure in multiple data centers, you should make sure your configuration/deployment tools take that into account.
 -	🔸[VPC Endpoints](http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-endpoints.html) are currently only available for S3 and DynamoDB. If you have a security requirement to lockdown outbound traffic from your VPC you may want to use [DNS filtering](https://aws.amazon.com/blogs/security/how-to-add-dns-filtering-to-your-nat-instance-with-squid/) to control outbound traffic to other services.
 -	❗Be careful when choosing your VPC IP CIDR block: If you are going to need to make use of [ClassicLink](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-classiclink.html), make sure that your private IP range [doesn’t overlap](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-classiclink.html#classiclink-limitations) with that of EC2 Classic.
 -	❗If you are going to peer VPCs, carefully consider the cost of [data transfer between VPCs](https://aws.amazon.com/vpc/faqs/#Peering_Connections), since for some workloads and integrations, this can be prohibitively expensive.
