Overview

Reviews

In this course, you will examine ways to architect, design, and build software —particularly distributed systems—for the muck and mire of the real world. You will prepare for the armies of illogical users who do crazy, unpredictable things. Your software will be under attack from the moment you release it. It needs to stand up to the typhoon winds of flash mobs or the crushing pressure of a DDoS attack by poorly secured IoT toaster ovens. You’ll take a hard look at software that failed the test and find ways to make sure your software survives contact with the real world. The course is divided into four parts, each introduced by a case study. In Part I: Create Stability you’ll see how to keep your systems alive, maintaining system uptime. In Part II: Design for Production, you’ll see what it means to live in production. In Part III: Deliver Your System, you’ll look at deployments. In Part IV: Solve Systemic Problems, you’ll examine the system’s ongoing life as part of the overall information ecosystem.
