AWS Regions provide fault isolation boundaries that prevent correlated failure and contain the impact from AWS service impairments to a single Region when they occur. You can use these fault boundaries to build multi-Region applications that consist of independent, fault-isolated replicas in each Region that limit shared fate scenarios. This allows you to build multi-Region […]

2023 was a rollercoaster year in tech, and we at the AWS Architecture Blog feel so fortunate to have shared in the excitement. As we move into 2024 and all of the new technologies we could see, we want to take a moment to highlight the brightest stars from 2023. As always, thanks to our […]

Welcome to the third post of a multi-part series that addresses disaster recovery (DR) strategies with the use of AWS-managed services to align with customer requirements of performance, cost, and compliance. In part two of this series, we introduced a DR concept that utilizes managed services through a backup and restore strategy with multiple Regions. […]

This post was originally published in June 2022 and is now updated with more information on efficiently architecting resilient patterns in the cloud. Architecting workloads for resilience on the cloud often need to evaluate multiple factors before they can decide the most optimal architecture for their workloads. Example Corp has multiple applications with varying criticality, […]

In part 1 of this series, we introduced a disaster recovery (DR) concept that uses managed services through a single AWS Region strategy. In part two, we introduce a multi-Region backup and restore approach. With this approach, you can deploy a DR solution in multiple Regions, but it will be associated with longer RPO/RTO. Using a […]

The Availability and Beyond whitepaper discusses the concept of static stability for improving resilience. What does static stability mean with regard to a multi-Region disaster recovery (DR) plan? What if the very tools that we rely on for failover are themselves impacted by a DR event? In this post, you’ll learn how to reduce dependencies […]

Data is at the center of stateful applications. Data consistency models will vary when choosing in-Region vs. multi-Region. In this post, part 2 of 3, we continue to filter through AWS services to focus on data-centric services with native features to help get your data where it needs to be in support of a multi-Region […]

Many AWS services have features to help you build and manage a multi-Region architecture, but identifying those capabilities across 200+ services can be overwhelming. In this 3-part blog series, we filter through those 200+ services and focus on those that have specific features to assist you in building multi-Region applications. In Part 1, we’ll build […]

This 3-part blog series discusses disaster recovery (DR) strategies that you can implement to ensure your data is safe and that your workload stays available during a disaster. In Part I, we’ll discuss the single AWS Region/multi-Availability Zone (AZ) DR strategy. The strategy outlined in this blog post addresses how to integrate AWS managed services […]

Voice calling systems are prevalent and necessary to many businesses today. They are usually designed to provide a 24×7 helpline support across multiple domains and use cases. Reliability and availability of such systems are important for a good customer experience. The thoughtful design of a cost-optimized solution will allow your business to sustain the system […]
