Multi-AZ deployment: Production infrastructure — load balancer, application tier, database, and search — is deployed across multiple availability zones within each region. Stateful caches and network egress operate within the multi-AZ subnet group.

Zero-downtime deployments: Rolling updates for container services ensure deployments are carried out without downtime.

24/7 monitoring: Automated monitoring with on-call rotation. Critical alerts are delivered through redundant notification channels. Documented response SLAs apply to S1/S2 incidents.

Automatic pre-deployment snapshots: Before every production deployment, a database snapshot is automatically created to enable quick rollbacks.

Status page: Available for customer communication during incidents.

Maintenance windows: Database maintenance takes place within a defined off-peak maintenance window. Most deployments are interruption-free.
