"Practical C++ Backend Programming" is a comprehensive walkthrough that provides readers with the necessary tools and knowledge to become proficient C++ backend developers. With a strong focus on real-world application and practical implementation, this book takes readers on a journey through the multifaceted landscape of backend development, making it an essential resource for any aspiring or current backend developer.Starting with the basics, the book introduces C++, providing a solid foundation in the language, its structure, and core concepts with regards to backend programming. From there, readers dive into the more complex elements of backend development. Through our engaging sections, use-cases and sample examples, readers are introduced to advanced topics such as concurrent programming, exploring threading and multiprocessing to handle intensive computational tasks, thus laying the groundwork for scalable applications.This book offers an in-depth look into APIs, specifically gRPC, along with caching strategies, and database management, using MongoDB as a NoSQL database of choice. All the while, readers will learn to implement these technologies in a practical context, building a blog application from scratch, thereby bridging the gap between theory and practical implementation. An entire section is dedicated to securing applications, wherein the book teaches authentication, authorization, and database security, and demonstrates how to implement these measures in the blog application.Another utmost important part of this book is to cover testing strategies, teaching the reader how to employ Google Test (gtest) to create robust and fail-proof backend solutions. Finally, the journey culminates in a step-by-step walkthrough to deploying applications on AWS, ensuring the reader is equipped with the necessary skills to take their applications live.Key LearningsDetailed overview of C++ programming, catering to both beginners and experienced coders.Practical exploration of concurrent programming for scalable and efficient application design.Comprehensive understanding of API usage, specifically using the gRPC framework.Deep dive into MongoDB for effective NoSQL database management and operations.Thorough walkthrough to implementing caching strategies for performance optimization.Strategic use of Nginx for handling web server needs including load balancing.Hands-on guide to implementing security measures for databases, APIs, and web servers.Instruction on employing Google Test for robust application testing and debugging.Step-by-step guidance for deploying applications on AWS, ensuring real-world readiness.Practical application of concepts via building and refining a blog application.Table of ContentIntroduction to Backend DevelopmentC++ Refresher and EssentialsDeep Dive into AlgorithmsMastering Version Control - Git and GitHubManaging Database Operations with MongoDBCrafting Rest APIs with gRPCDealing with Client-side and Server-side CachingManaging Web Servers with NginxTesting Your C++ BackendSecuring Your C++ BackendDeploying Your ApplicationAudienceThis book is appropriate for readers with some background in C++ and nothing about back-end development. It's great for those just getting their feet wet in back-end, as well as seasoned pros looking to hone their craft and learn something new. Whether you're a student, or professional this book will teach you everything you need to know to master the art of C++ back-end development.

This second edition teaches C++ programmers the practical skills and modern strategies they need to build strong backend systems. All you need is some basic knowledge of C++, and this book will teach you everything else you need to become a backend developer. Each chapter shows you step-by-step examples, real code, and workflows that you can follow to get results. The book starts with the basic structure of backend systems and shows how APIs are the most important way of communicating and how to use high-performance solutions like gRPC to go beyond REST. It will teach you to use, test and improve API endpoints in realistic C++ projects. This will help you to feel more confident in designing contracts first and in real-time data flows. The key parts of the book teaches you to cache things, to make sure your data is correct and to avoid common problems with correct troubleshooting. A big part of the book looks at how to set up and manage modern web servers. It teaches you to use C++ applications with Nginx, SSL, reverse proxies and load balancers in a way that's easy to understand. We then move on to more practical chapters on automated testing, including both unit and integration tests. You get to learn about containerisation, cloud deployment using AWS Elastic Beanstalk, environment configuration, monitoring, and scaling, and all this is taught step-by-step. The book makes use of simple and clear to teach network programming, how things are set up, and the important patterns that are used in today's distributed systems. While you learn, you please make a note that this edition is focused on practical scenarios and does not attempt to cover highly complex or edge-case architectures.Key Features Learn to design APIs and high-performance gRPC endpoints and services. Create and protect backend apps using environment variables, secrets, and strong configuration management. Use advanced caching strategies, including in-memory, Redis, and custom eviction for scalable backends. Set up and optimise Nginx as a web server, reverse proxy, and SSL-enabled application gateway. Use Google Test to perform unit and integration testing. Use Docker to create containers. Use AWS Elastic Beanstalk to deploy backends into production. Use AWS CloudWatch, alarms, and custom log analytics to check the health of apps and resources Set up ways to integrate and migrate databases with no deployment errors. Keep systems updated, roll back if necessary, and make customizations to respond changing traffic and business demands.Table of Content Introduction to Backend Development C++ Refresher and Essentials Deep Dive into Algorithms Mastering Git and GitHub Managing Database Operations with MongoDB Crafting REST APIs with gRPC Dealing with Client-Side and Server-Side Caching Managing Web Servers with Nginx Testing C++ Backend Deploying Application
