The following list summarizes VPC best practices:
- Before starting to design and implement AWS VPC, it is essential to understand present and future needs. It is recommended that you plan your VPC architecture, considering the minimum requirement for the next two years. Once the infrastructure is created on a VPC, making any changes in the VPC requires redesigning and recreating infrastructure. Lateral changes in the design and infrastructure can be very time-consuming and expensive.
- It is suggested that you use a CIDR range as per RFC 1918. Also, make sure that a sufficient number of IP addresses are available in each subnet to match with present and future needs. Ensure that the CIDR range in AWS does not conflict with the CIDR range used in any other data center or VPC where you may have to establish a VPN or Direct Connect connection.
- Remember, AWS reserves...
