Hands-On Software Engineering with Python

By: Brian Allbee, Nimesh Verma

Overview of this book

Software Engineering is about more than just writing code—it includes a host of soft skills that apply to almost any development effort, no matter what the language, development methodology, or scope of the project. Being a senior developer all but requires awareness of how those skills, along with their expected technical counterparts, mesh together through a project's life cycle. This book walks you through that discovery by going over the entire life cycle of a multi-tier system and its related software projects. You'll see what happens before any development takes place, and what impact the decisions and designs made at each step have on the development process. The development of the entire project, over the course of several iterations based on real-world Agile iterations, will be executed, sometimes starting from nothing, in one of the fastest growing languages in the world—Python. Application of practices in Python will be laid out, along with a number of Python-specific capabilities that are often overlooked. Finally, the book will implement a high-performance computing solution, from first principles through complete foundation.

The Artisan Gateway Service

In order to implement the end user and Gateway-daemon communications, we need to examine and make some decisions on several operational aspects of the daemon  how it's going to work, how data gets sent and received, and how that data is acted upon. In this chapter, we'll examine that in detail, and write code to implement processes based on those decisions.

The chapter covers the following topics:

  • Defining what the data structure (messages) being sent back and forth looks like, and what it needs to provide, including a signed-message implementation that should work no matter what mechanism is used to send the data
  • Examining two fundamental options for sending and receiving data: message queues and web services
  • How messages will be handled, independently of the transmission mechanism
  • The basic structures needed to implement...
