RES05-04 Reserving IP Resources for Expansion and HA

The cloud networks must support scalability and high availability to provide sufficient resources during automatic scaling or service expansion on the cloud.

  • Risk level

    High

  • Key strategies

    The cloud network planning and design must meet the following requirements:

    • Plan separate VPCs for each region based on service needs. Assign independent address spaces to each VPC. Reserve IP address spaces for creating VPCs.
    • Plan subnets and IP address spaces for each VPC based on service needs. Reserve IP address spaces for creating subnets.
    • Reserve IP address spaces for each subnet for network capacity expansion.
    • Connect your network to others like VPCs, IDCs, or other clouds only if their IP address spaces do not conflict.
