Resilience patterns and trade-offs

Understand resiliency patterns and trade-offs to architect efficiently in the cloud

Architecting workloads to achieve your resiliency targets can be a balancing act. Firms designing for resilience on 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, and each of their applications have different needs in terms of resiliency, […]

Multi-Region backup

Disaster recovery with AWS managed services, Part 2: Multi-Region/backup and restore

In part I 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 […]

Minimizing Dependencies in a Disaster Recovery Plan

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 […]

Building an application with AWS multi-Region services using services covered in Part 1

Creating a Multi-Region Application with AWS Services – Part 2, Data and Replication

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 […]

Creating a Multi-Region Application with AWS Services – Part 1, Compute, Networking, and Security

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 […]

Single Region/multi-AZ with secondary Region for backups

Disaster Recovery with AWS Managed Services, Part I: Single Region

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 […]

Disaster Recovery (DR) for a Third-party Interactive Voice Response on AWS

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 […]

DR implementation architecture on multi-Region active-passive workloads

Implementing Multi-Region Disaster Recovery Using Event-Driven Architecture

In this blog post, we share a reference architecture that uses a multi-Region active/passive strategy to implement a hot standby strategy for disaster recovery (DR). We highlight the benefits of performing DR failover using event-driven, serverless architecture, which provides high reliability, one of the pillars of AWS Well Architected Framework. With the multi-Region active/passive strategy, your workloads […]

Disaster Recovery (DR) Architecture on AWS, Part IV: Multi-site Active/Active

In my first blog post of this series, I introduced you to four strategies for disaster recovery (DR). My subsequent posts shared details on the backup and restore, pilot light, and warm standby active/passive strategies. In this post, you’ll learn how to implement an active/active strategy to run your workload and serve requests in two […]

Disaster Recovery (DR) Architecture on AWS, Part III: Pilot Light and Warm Standby

In this blog post, you will learn about two more active/passive strategies that enable your workload to recover from disaster events such as natural disasters, technical failures, or human actions. Previously, I introduced you to four strategies for disaster recovery (DR) on AWS. Then we explored the backup and restore strategy. Now let’s learn about […]
