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
