Architecture Failover Whitepaper

Figure 2 shows the four strategies for DR that are highlighted in the DR whitepaper. All requests are now switched to be routed there in a process called “failover.” For tighter RTO/RPO objectives, the data is maintained live, and the infrastructure is fully or partially deployed in the recovery site before failover.

Route 53 Private Hosted Zones (PHZs) and Resolver endpoints on AWS create an architecture best practice for centralized DNS in hybrid cloud environment. This blog presents an architecture that provides a unified view of the DNS while allowing different AWS accounts to manage subdomains. Architecture Overview.

The architecture in Figure 2 shows you how to use AWS Regions as your active sites, creating a multi-Region active/active architecture. To maintain low latencies and reduce the potential for network error, serve all read and write requests from the local Region of your multi-Region active/active architecture. DR strategies.

By using the best practices provided in the AWS Well-Architected Reliability Pillar whitepaper to design your DR strategy, your workloads can remain available despite disaster events such as natural disasters, technical failures, or human actions. Failover and cross-Region recovery with a multi-Region backup and restore strategy.

The left AWS Region is the primary Region that is active, and the right Region is the recovery Region that is passive before failover. When a disaster occurs, successful recovery depends on detection of the disaster event, restoration of the workload in the recovery Region, and failover to send traffic to the recovery Region.

In this blog, we talk about architecture patterns to improve system resiliency, why observability matters, and how to build a holistic observability solution. Minimum business continuity for failover. Current Architecture with improved resiliency and standardized observability. Predictive scaling for EC2. Conclusion.

The Availability and Beyond whitepaper discusses the concept of static stability for improving resilience. What if the very tools that we rely on for failover are themselves impacted by a DR event? Failover plan dependencies and considerations. Relying on an automated health check to control Regional failover can be tricky.
