Resilient by Default: Highly Available Cloud Patterns

Failure is inevitable—resilience is a choice. Resilient by Default is a cloud computing book devoted to designing systems that remain available, responsive, and trustworthy even when components fail.
The writing reframes resilience as a design principle, not a reaction. Readers explore how cloud-native patterns—redundancy, isolation, graceful degradation, and automated recovery—turn failure into a manageable event rather than a catastrophe.
Rather than focusing on single techniques, the book emphasizes system thinking. It explains how availability emerges from architecture, not heroics, and how trade-offs between cost, complexity, and reliability must be made consciously. Each chapter shows how resilient systems fail safely, recover quickly, and protect user experience.
The tone is structured and practical, aimed at architects and engineers responsible for uptime. Language remains precise and actionable, translating reliability goals into architectural patterns.
Resilient by Default moves through multi-zone design, fault isolation, load management, monitoring, and recovery strategies—demonstrating how resilience is engineered upfront.
Key themes explored include:
• High availability patterns
• Designing for failure
• Fault tolerance and isolation
• Graceful degradation
• Reliability as architecture
Resilient by Default is for teams building trust—offering a blueprint to ensure systems stay available when it matters most.
