Failure to deploy cluster template in AWS

[Vladimir]

Template keeps rolling back with this message:

Embedded stack arn:aws:cloudformation:us-east-1:256456036607:stack/Check-Point-Cluster-ClusterStack-Z9KT09CQRK20/9edef850-aa14-11e7-836b-503f23fb5536 was not successfully created: The following resource(s) failed to create: [ClusterRole, ClusterPublicAddress, AMI, InternalRoutingTable, MemberAPublicAddress, InstanceSecurityGroup, MemberBPublicAddress].

Are there any limitations that i am not aware of, (i.e. minimum subnet size, etc.), or am I missing something?

Sorry for repeatedly answering my own questions, but it may come handy for someone bumping into same issues.

The problem was caused by the AWS EIP limit of 5 per region.

If you are experiencing it in the lab environment, chose another region.

In production, contact AWS and request the limit increase.
