In more details:
We have 2 Windows Servers 2012 running SQL Server Web on Amazon EC2 in the same VPC.
Network adapters are configured with static private IP-s via AWS console.
At Widows level, however when you go to Network Adapter Properties/IPV4/Properties it shows:
Obtain an IP address automatically
Obtain DNS server automatically
So what happens is that each time network adapters receive the same IP dynamically (for instance, 10.0.0.20 for one server and 10.0.0.21 for another).
Are there any implications of having Windows Server (or SQL Server) configured that way?
Should I in addition to assignment via Amazon AWS also set the same static IP for network adapter at Windows level?
Or should I set it to dynamic as AWS level and assign static addresses at Windows level?
