Building Production-Grade Backend Systems - Advanced Systems (Book 2)

Building Production-Grade Backend Systems - Advanced Systems (Book 2)Design Microservices, Build Integrations, and Scale Backend InfrastructureModern applications need more than working code-they need backend systems that can communicate reliably, integrate with external services, handle failures, and scale as demand grows. Building Production-Grade Backend Systems - Advanced Systems (Book 2) provides a practical guide to designing and building advanced backend architectures with a strong focus on microservices, integrations, resilience, and scalability.Written for developers who want to move beyond basic API development, this book explains how independent services communicate, how distributed systems manage data, and how backend applications connect with the tools and platforms businesses rely on every day.What You Will LearnMicroservices Architecture: Understand service boundaries, architectural principles, communication patterns, service discovery, load balancing, and database strategies for distributed applications.Messaging and Distributed Communication: Build systems using synchronous communication, asynchronous messaging, message queues, event-driven architecture, REST APIs, gRPC, and Protocol Buffers.API Gateway and Service Infrastructure: Learn practical API Gateway patterns, service discovery, traffic management, and infrastructure approaches for reliable microservice environments.Data Management: Work with polyglot persistence, data consistency challenges, Saga patterns, database replication, and architecture decisions for distributed systems.Real-World Integrations: Build backend connectors and integrations with SMTP/email services, Slack, Jira, Notion, Gmail, AWS S3, Google Cloud, Azure Blob, payment gateways, and third-party SaaS platforms.Reliability and Resilience: Implement rate limiting, quota management, error handling, retry strategies, circuit breakers, fallbacks, and webhook handling for dependable production systems.Scalability: Understand horizontal scaling, vertical scaling, load balancing, database replication, performance optimization, and the architectural trade-offs involved in growing backend infrastructure.Practical Project: Apply the concepts in a real-world project focused on building a multi-service integration platform, bringing together microservices, external APIs, messaging, integrations, resilience, and scalable infrastructure.Who This Book Is ForThis book is suitable for backend developers, full-stack developers, software engineers, API developers, system architects, DevOps-oriented developers, and technology professionals who want practical knowledge for building production-grade backend systems.About the AuthorIsrael Joshua Chukwubueze, formerly known as Christopher Ekene Okade, has over 14 years of experience in web and mobile application design and development. His passion for technology, writing, teaching, and sharing practical knowledge inspired him to create this book as a valuable resource for developers building modern software systems.Whether you are strengthening your backend skills or working toward enterprise-level application development, this book gives you practical concepts and architectural patterns you can apply to real software projects.
