Environment architecture considerations
Consider the following criteria in deciding how to configure your environment and architecture.
Will your virtual data center connect back to your corporate network?
Do you have an existing AWS DirectConnect service or do you require a new DirectConnect service?
Do you have an existing VPN connection or do you require a new VPN service?
What is the available CIDR block range of internal addresses that you could allocate? (/16 recommended, must not overlap corporate network ranges)
Will your virtual data center require internet access?
Which Region(s) do you intend to use? (Sydney/N. Virginia/Dublin)
Will you require a Shared Services subnet to host applications that have connectivity to all other subnets?
What are your organizational divisions that you would like to be hosted as separate subnets. For each:
What connectivity to other subnets do you need?
Does the subnet require Internet access?
Are there any application deployment restrictions to that subnet?
Are there any particular network requirements for that subnet?
Would you like separate development and/or test environments? (Will include shared services duplicate for anytime access)
What are your snapshot backup requirements?
Do you have an existing maintenance process or patch window(s) that you would like to keep?
What are your domain registration requirements?
Do you have any single sign-on requirements? (e.g., AD, LDAP)
What are your overall expected operating system and anticipated capacity requirements?
