The JSON protocol is the most common method software systems use to communicate with each other, but is it the best choice? This course will teach you about protocol buffers, a faster, more efficient, and more flexible system for inter-service communication.

Modern software systems rely on fast, efficient inter-service messaging to meet performance demands in distributed environments. In this course, Protocol Buffers Fundamentals, you'll learn to adopt this high-performance technology. First, you'll explore the secrets that protocol buffers so fast and efficient. Next, you'll discover how to construct your own messaging systems. Finally, you'll learn how to maintain your message definitions as your system's needs evolve. When you're finished with this course, you'll have the skills and knowledge of protocol buffers needed to build systems with blazingly fast and efficient messaging.
