Overview of this book

Awarded as one of the best books of all time by BookAuthority, Cloud Native Programming with Golang will take you on a journey into the world of microservices and cloud computing with the help of Go. Cloud computing and microservices are two very important concepts in modern software architecture. They represent key skills that ambitious software engineers need to acquire in order to design and build software applications capable of performing and scaling. Go is a modern cross-platform programming language that is very powerful yet simple; it is an excellent choice for microservices and cloud applications. Go is gaining more and more popularity, and becoming a very attractive skill. This book starts by covering the software architectural patterns of cloud applications, as well as practical concepts regarding how to scale, distribute, and deploy those applications. You will also learn how to build a JavaScript-based front-end for your application, using TypeScript and React. From there, we dive into commercial cloud offerings by covering AWS. Finally, we conclude our book by providing some overviews of other concepts and technologies that you can explore, to move from where the book leaves off.

DynamoDB 


DynamoDB is a very important part of the AWS ecosystem; it typically serves as the backend database for numerous cloud native applications. DynamoDB is a distributed high-performance database hosted in the cloud, which is offered as a service by AWS. 

DynamoDB components

Before we discuss how to write code that can interact with DynamoDB, we will need to first cover some important concepts regarding the database. DynamoDB consists of the following components:

  • Tables: Like a typical database engine, DynamoDB stores data in a collection of tables. For example, in our MyEvents application, we can have an events table that would store events information such as concert names and start dates. Similarly, we can also have a bookings table to host booking information for our users. We can also have a users table to store our users information.
  • Items: Items are nothing more than the rows of the DynamoDB tables. Information inside an item is known as attributes. If we take the events table...
