Resilience in AWS Private 5G

The AWS global infrastructure is built around AWS Regions and Availability Zones. Regions provide multiple physically separated and isolated Availability Zones, which are connected through low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure.

You are limited in what you can do to improve resiliency of your Private 5G network. Spectrum Access System (SAS) is the cloud service that provides spectrum grants in Citizens Broadband Radio Service (CBRS). If SAS goes down, your network cannot operate. AWS performs on-going maintenance during maintenance windows. During these maintenance windows, your Private 5G network may become unavailable for short periods of time. For more information, see Spectrum Access System (SAS) and Network maintenance for AWS Private 5G.
