A good strategy for resilience will include operating with high availability and planning for business continuity. It also accounts for the incidence of natural disasters, such as earthquakes or floods and technical failures, such as power failure or network connectivity. AWS recommends a multi-AZ strategy for high availability and a multi-Region strategy for disaster recovery. […]

This post was co-written with Luke Sudgen, Lead DevOps Engineer Post Trade, and Padraig Murphy, Solutions Architect Post Trade, from London Stock Exchange Group. In this post, we’ll discuss some failure scenarios that were tested by London Stock Exchange Group (LSEG) Post Trade Technology teams during a chaos engineering event supported by AWS. Chaos engineering […]

What is “resiliency”, and why does it matter? When we discussed this topic in an early 2022 edition of Let’s Architect!, we referenced the AWS Well-Architected Framework, which defines resilience as having “the capability to recover when stressed by load, accidental or intentional attacks, and failure of any part in the workload’s components.” Businesses rely […]

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, […]

As we wrap up 2022, we want to take a moment to shine a bright light on our readers, who spend their time exploring our posts, providing generous feedback, and asking poignant questions! Much appreciation goes to our Solutions Architects, who work tirelessly to identify and produce what our customers need. Without any further ado, […]

NoSQL databases are an essential part of the technology industry in today’s world. Why are we talking about NoSQL databases? NoSQL databases often allow developers to be in control of the structure of the data, and they are a good fit for big data scenarios and offer fast performance. In this issue of Let’s Architect!, […]

The following is an early preview of new guidance to be published as part of updates to the AWS Well-Architected content: Chaos Engineering enables us to find shortcomings before our customers find them and therefore, provides us with the opportunity to create a better customer experience. Chaos Engineering does not introduce chaos into your systems, […]

As customers commit to a DevOps mindset and embrace a nearly continuous integration/continuous delivery model to implement change with a higher velocity, assessing every change impact on an application resilience is key. This blog shows an architecture pattern for automating resiliency assessments as part of your CI/CD pipeline. Automatically running a resiliency assessment within CI/CD […]

In Part 1 of this series, we built a foundation for your multi-Region application using AWS compute, networking, and security services. In Part 2, we integrated AWS data and replication services to move and sync data between AWS Regions. In Part 3, we cover AWS services and features used for messaging, deployment, monitoring, and management. […]

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 […]
