ADVREL07-BP01 Design your workloads to withstand failures of individual components, such as compute instances, queues, databases, and caches

Build building resilient advertising systems by identifying critical components, and implement fault tolerance through cell-based architectures and distributed resources across Availability Zones.

Implementation guidance

Determine which components of your workload are in a critical path to maintain operations for real-time bidding, ad serving, and other crucial functions. Identify AWS services that provide built-in fault tolerance mechanisms which are within your workload's response time, RTO, and RPO targets. Use cell-based architectures, with resources spread across multiple availability zones, to reduce the scope of a disruptive event. Where consistent communications are necessary, implement static stability mechanisms to reduce the dependency on control plane actions.
