Inter-Service Communication with Go
Communication is simple if you know the right way KEY FEATURES ● Understand the core concepts related to inter-service communication. ● Learn and understand different inter-service communication approaches through practical examples. ● Recognize the most suitable communication concept for your software solution. DESCRIPTION This book will cover different concepts of inter-service communication. They will be demonstrated through the Go programming language, its standard library, and popular third-party packages for concepts. Begin by understanding basic concepts such as clients, servers, and communication methods. Explore RESTful APIs and HTTP, the backbone of many systems. Learn about protocol buffers and gRPC for efficient data exchange. For asynchronous communication, discover message queuing with RabbitMQ and event-driven patterns with Redis. Lastly, explore event-driven architecture (EDA) and Apache Kafka for implementing this style of communication. After reading this book, a reader can determine which communication concept is most suitable for the software solution based on software solution requirements. WHAT YOU WILL LEARN ● Decide which inter-service communication concept is most suitable for a particular software solution. ● Implement different communication approaches with the Go programming language. ● Utilize implementations from the Go’s standard library and third-party packages. ● Use API design best practices. ● Avoid issues that can arise from the wrong choice of communication concept. WHO THIS BOOK IS FOR It caters to developers, software engineers, and architects looking to master inter-service communication for their Go projects. TABLE OF CONTENTS 1.

Programming Backend with Go
This book takes its time to go over every important aspect of backend programming, from the fundamentals to more advanced techniques, so that you can become experts in Go scripting and all the things Go can do. Quickly introducing readers to Go and its ecosystem, the book walks them through installing the language and creating a development environment with Visual Studio Code. Next, it takes a baby step into learning the basics of building web servers with the net/http package, going over topics like routing, handling various HTTP methods, and the structures of requests and responses. Path variables, regex-based routing, custom handlers, and middleware are some of the advanced routing topics covered, which uses the robust gorilla/mux package. After introducing session and cookie management, the book moves on to user authentication, covering topics such as OAuth2 integration, JWT for secure APIs, and more. The book then teaches various aspects of database integration with GORM, covering topics such as connecting to SQL databases, performing CRUD operations, managing migrations, and handling transactions and concurrency control. The Gin framework for designing and implementing microservices, REST and gRPC for inter-service communication, and Kubernetes for containerizing applications are also covered in detail. Also covered is message brokering with Apache Kafka and NSQ for asynchronous systems, which guarantees resilient systems and efficient message delivery. Secure coding practices, HTTPS with crypto/tls, avoiding SQL injections and XSS attacks, and configuration management with Viper are also one of the main goal of the book. Last but not least, the book covers testing and debugging with tools such as Delve, Testify, and GoMock. It then teaches readers through various deployment strategies, such as blue-green, canary, and rolling deployments with AWS CodeDeploy. Utilizing Go's robust features and clean scripting capabilities, this book provides you with the necessary knowledge and skills to develop secure, scalable, and resilient backend systems. Key Learnings Get to know Go's ecosystem and tools to set up and configure backend development efficiently. Web servers can be easily built and managed using Go's net/http package for dynamic content delivery. Use gorilla/mux to implement advanced routing techniques for flexible URL handling. Implement strong API security with user authentication using OAuth2 and JWT. Make use of GORM's advanced capabilities of migrations and transactions, to integrate SQL databases. Use Gin, Kubernetes, and gRPC to build and launch scalable microservices. Make use of NSQ and Kafka for asynchronous processing. Prevent frequent vulnerabilities of SQL injection and XSS attacks. Use Testify, GoMock, and Delve to streamline testing and debugging. Use AWS CodeDeploy with blue-green and canary deployment strategies to deploy applications. Table of Content Understanding Go for Backend Development Building a Basic Web Server with net/http Advanced Routing with gorilla/mux User Authentication with Oauth2 and JWT Integrating Databases with GORM Creating Microservices in Go Message Brokering with NSQ and Apache Kafka Securing Go Applications Testing and Debugging Go Applications Deploying Go Applications Must Read by: Web developers, non-Go programmers, full-stack developers, and anyone else interested in learning the ins and outs of backend development with Go will find "Programming Backend with Go" to be an incredibly practical, use-case oriented, and illustrated learning resource.
