Let’s Architect! Creating resilient architecture

{"value":"The [AWS Well-Architected Framework](https://aws.amazon.com/architecture/well-architected/) defines resilience as “the capability to recover when stressed by load (more requests for service), attacks (either accidental through a bug, or deliberate through intention), and failure of any component in the workload’s components.”\n\nThe need for resilient workloads transcends all customer industries, but it can often can be misunderstood, which can lead to workloads that do not incorporate resilient architecture at all or workloads that are over-engineered.\n\nResilience is a technical problem, but it’s also about people and culture. It’s a continuous process that requires us to learn by iterating. Customers need to understand, from a business perspective, what their SLA requirements are, and from technical perspective, how they achieve this with their architecture. In this post, we share resources to help you build resilience into your AWS architecture.\n\n\n#### **[Amazon’s approach to building resilient services](https://www.youtube.com/watch?v=KLxwhsJuZ44)**\n\n\nBuilding a resilient architecture is not only about the technical implementation of the system, but also about the solutions for observability, operations, and people.\n\nThis video shows the Amazon approach for designing resilient systems, where individual teams build and own a service. This way, everyone has operational responsibility. You’ll learn how to deploy often, move fast, and design solutions for automatic rollback, which allows teams to revert their workload to a previous iteration if needed.\n\n[](https://d2908q01vomqb2.cloudfront.net/fc074d501302eb2b93e2554793fcaf50b3bf7291/2022/05/19/The-pillars-adopted-by-the-engineering-teams-building-services-at-Amazon.jpg)\n\nThe pillars adopted by the engineering teams building services at Amazon\n\n\n#### **[Five design patterns to build more resilient applications](https://www.youtube.com/watch?v=CDX7oQkuf3A)**\n\n\nResilience is an important consideration for developers. For instance, if a downstream service is not available, how can the software handle the situation? Which mechanisms should you use to implement retries? How can you prevent overloading the downstream service?\n\nThis video focuses on five strategies and design patterns that developers can use to build resilient applications. You’ll learn how to add timeouts, retries, exponential backoff with randomness, and circuit breakers into your code. These patterns are powerful because they can be abstracted and implemented in different scenarios.\n\n[](https://d2908q01vomqb2.cloudfront.net/fc074d501302eb2b93e2554793fcaf50b3bf7291/2022/05/19/Software-developers-can-implement-different-strategies-in-their-application-code-to-design-for-resiliency.jpg)\n\nSoftware developers can implement different strategies in their application code to design for resiliency\n\n\n#### **[Building Resilient Well-Architected Workloads Using AWS Resilience Hub](https://aws.amazon.com/blogs/architecture/building-resilient-well-architected-workloads-using-aws-resilience-hub/)**\n\n\nThis blog post shows you how [AWS Resilience Hub](https://aws.amazon.com/resilience-hub/) can help you evaluate the resilience of your architecture. It gives you a central place to monitor, track, and evaluate your application’s resiliency based on your business goals. For example, after you define your RPO and RTO SLAs, Resilience Hub will evaluate your current architecture against them and show you whether you’ve met your goals. If you haven’t met your goals, it recommends changes to help you meet them.\n\n[](https://d2908q01vomqb2.cloudfront.net/fc074d501302eb2b93e2554793fcaf50b3bf7291/2022/05/19/Multi-AZ-architecture-incorporating-data-backup-features.jpg)\n\nMulti-AZ architecture incorporating data backup features\n\n\n#### **[Incorporating continuous resilience in your development ecosystem](https://www.youtube.com/watch?v=pbXEH96zhUg)**\n\n\nResilience encompasses a broad range of considerations, including infrastructure, application patterns, data management, and application building and monitoring. And after you incorporate resilience, it is essential to continuously maintain it.\n\nThis video provides useful principles for building continuous resilience in your applications. It also explores various considerations for implementing processes designed to provide continuous improvement through a DevOps methodology and shows you services you can use to incorporate resilience in the development process in a nearly continuous manner.\n\n[\n](https://d2908q01vomqb2.cloudfront.net/fc074d501302eb2b93e2554793fcaf50b3bf7291/2022/05/19/Software-architects-can-implement-several-patterns-to-prevent-failures-or-being-fault-tolerant.jpg)\n\nSoftware architects can implement several patterns to prevent failures or being fault-tolerant\n\n\n#### **See you next time!**\n\n\nThanks for joining our discussion on resilient architecture!
