Beginning Ballerina Programming: From Novice to Professional

Discover the Ballerina programming language for next-generation microservices and native cloud application development. This book shows you that Ballerina is a cutting-edge programming language, which incorporates many of the latest technological advancements in programming language theory. You'll learn variables and types, modules and functions, flow control, error handling, concurrency, I/O, cloud/network programming, persistence and data access, security and more.
Additionally, Beginning Ballerina Programming introduces many foundation computer science topics along the way and doesn't assume much prior knowledge. For example, when introducing transport-level security, you will get a brief introduction to public-key cryptography, how it is different from private-key cryptography, and why we need it. This provides an added bonus for you to learn something new and general in computer science.
After reading and using this book, you'll be proficient with Ballerina and cloud-first programming and apply these concepts and techniques to your next cloud application developments.

What You'll Learn

• Start programming with Ballerina
• Gain the basics of network communication and programming
• Obtain a solid understanding of services/API development and resilient communication
• Discover cloud-native technologies using Ballerina
• Deploy to the cloud using Ballerina

Who This Book Is For
Absolute beginners in computer programming: No prior experience with computer programming is expected. This can also be a reference book for experienced developers in other languages, who want to learn a modern programming language.

探索Ballerina程式語言，用於下一代微服務和原生雲應用程式開發。本書向您展示Ballerina是一種尖端的程式語言，融合了許多最新的程式語言理論技術。您將學習變數和類型、模組和函數、流程控制、錯誤處理、並行處理、I/O、雲端/網路程式設計、持久性和資料存取、安全性等等。

此外，《Beginning Ballerina Programming》在介紹的過程中還引入了許多基礎的計算機科學主題，並不假設您有太多先備知識。例如，在介紹傳輸層安全性時，您將獲得對公鑰加密的簡要介紹，以及它與私鑰加密的區別以及為什麼我們需要它。這為您學習計算機科學中的新知識提供了額外的好處。

閱讀並使用本書後，您將熟練掌握Ballerina和以雲為先的程式設計，並將這些概念和技術應用於下一個雲應用程式開發中。

您將學到什麼：
