Cloud Resiliency

Practical Patterns for Real-World Outages

Cloud reliability is not a tool. It is an architectural discipline. The right mix of multi-availability-zone (multi-AZ) and multi-region deployments, thoughtful failover at the DNS and data layers, and routine game-days turns incidents into non-events.

This month’s picks focus on clear, vendor-backed guidance you can act on right away, plus a couple of books your leaders can use to set a durable playbook.

Reliability Pillar – AWS Well-Architected Framework

By AWS Well Architected

The AWS Well-Architected Framework helps you understand the pros and cons of decisions you make while building workloads on AWS. The Framework shows architectural best practices for designing and operating reliable, secure, efficient, cost-effective, and sustainable workloads in the cloud.

It provides a way to consistently measure your architectures against best practices and identify areas for improvement. This paper focuses on the reliability pillar and how to apply it to your solutions.

Disaster Recovery Planning Guide

By Google Cloud Architecture Center

This document provides an overview of the Disaster Recovery (DR) planning process.

Service-interrupting events can occur at any time — from network failures and software bugs introduced during an application deployment to large-scale natural disasters. A well-designed and thoroughly tested DR plan ensures the organization can respond effectively to these and other potential service disruptions.

What is Azure Reliability Documentation?

By Microsoft Ignite

The Azure reliability documentation provides service-specific guides on how each Azure service supports those platform reliability capabilities, such as transient fault handling, availability zones, multi-region support, and backup support.

To see the current list of reliability service guides, see Reliability guides by service.

Building Resilient Applications and Environments: Is Less More?

By Michael Cade

This concise 45-minute video covers application and environment resiliency. Even with the high availability and reliability of AWS, simply migrating or modernizing an application in the cloud does not guarantee resilience.

This demo-driven session illustrates what true data resilience looks like and how to build it. It goes beyond basic backup strategies to show how to create a resilient environment that enhances efficiency and security.
