PHP and Microservices: Architecture, Development, and Deployment

The world of PHP development is changing rapidly. Monolithic applications are giving way to flexible, scalable microservice architectures. The book "PHP and Microservices" is a practical guide that will take you through all stages of transformation: from the first decomposition of a monolith to production deployment in Kubernetes.

What is this book about?

This is not another syntax reference. It is a road map for architects and Senior developers. You will learn:

• How to properly "slice" business logic into independent services without creating a "Big Ball of Mud".
• Methods of inter-service communication: synchronous (REST, gRPC) and asynchronous (RabbitMQ, Kafka).
• Fault tolerance patterns: Circuit Breaker, Retry, Timeout, Bulkhead.
• Working with data: Database per Service, Saga Pattern, and CQRS.
• Containerization and orchestration: Docker Compose for local development and Kubernetes for production.
• API Gateway and Service Mesh using Envoy as an example.
• CI/CD pipelines for microservices.
• Monitoring, logging, and tracing (OpenTelemetry).

Who is this book for?

The book is intended for practicing PHP developers at the Middle+ and Senior levels who have already worked with frameworks (Laravel, Symfony) and want to move to the next level — designing distributed systems. It will also be useful for tech leads and architects looking for proven recipes for transitioning from a legacy monolith to a modern architecture.

What will you learn?

• Designing service boundaries using Domain-Driven Design (DDD).
• Implementing asynchronous interaction with queues.
• Configuring Service Discovery and load balancing.
• Writing tests for distributed systems (integration and contract tests).
• Deploying microservices in the cloud and managing configurations.

Each chapter contains real PHP code examples ready for use in your projects. You will get not just theory, but working tools for creating reliable and scalable applications.

The book "PHP and Microservices" will be your navigator in the world of distributed systems. Discover a new level of development — without fear of complexity, with a clear understanding of every step.
