"Designing Scalable APIs with AppSync"
"Designing Scalable APIs with AppSync" is a comprehensive guide to architecting, deploying, and operating robust GraphQL APIs using AWS AppSync. Beginning with the evolution from REST to GraphQL, the book provides a clear foundation in modern API design and delves into the nuances of the GraphQL specification, real-time subscriptions, and event-driven patterns. Readers are introduced to AppSync's core architecture and its seamless integration with the AWS ecosystem, all while emphasizing best practices for scalability, modular schema engineering, and schema-driven development workflows.
The book meticulously explores the intricacies of resolver development, including advanced mapping templates, batching strategies, and Lambda integrations, ensuring performant and maintainable data access. It presents in-depth strategies for securing APIs at every layer—covering authentication, fine-grained authorization, encryption, and attack mitigation—while addressing audit, monitoring, and observability through AWS-native tools. Real-world operational concerns are demystified, with actionable guidance on CI/CD pipelines, safe deployments, disaster recovery, testing frameworks, and cost optimization to ensure high availability and resilience in demanding production environments.
Designed for architects, backend engineers, and API developers, "Designing Scalable APIs with AppSync" goes beyond the basics to cover multi-source federation, orchestrated workflows, hybrid and legacy integrations, and the latest trends in API mesh, edge computing, and AI/ML-powered use cases. The final chapters equip teams with production-proven patterns, anti-patterns to avoid, and a look towards the future of API ecosystems. With practical patterns and deep technical insights throughout, this book is an indispensable resource for building enterprise-scale, future-ready APIs on AWS.
