Appendix: Reliability

How do you manage service quotas and constraints?

  • Be aware of service quotas and constraints
  • Manage service quotas across accounts and regions
  • Accommodate fixed service quotas and constraints through architecture
  • Monitor and manage quotas
  • Automate quota management
  • Ensure that a sufficient gap exists between the current quotas and the maximum usage to accommodate failover

How do you plan your network topology?

  • Use highly available network connectivity for your workload public endpoints
  • Provision redundant connectivity between private networks in the cloud and on-premises environments
  • Ensure IP subnet allocation accounts for expansion and availability
  • Prefer hub-and-spoke topologies over many-to-many mesh
  • Enforce non-overlapping private IP address ranges in all private address spaces where they are connected
