Over the past few years I have focused much of my learning and work choices around learning about the design of sociotechnical systems?—?how how to design software architectures and organise teams around them. As part of good design, we should consider the effects of changing all of these variables.

OS X, which used to trumpet “It just works,” has evolved to “it used to just work”; the most user-centric Unix-like system ever built now staggers under the load of new and poorly thought-out features. Most professional programmers work on large systems that can consist of thousands of functions and millions of lines of code.

Traditional monolithic architectures are built around the concept of large applications that are self-contained, independent, and incorporate myriad capabilities. As developers move to microservice-centric designs, components are broken into independent services to be developed, deployed, and maintained separately. Easier to develop.

This kata is split into four sections that address different aspects of architecting software systems. First with a domain quiz, and then by slicing up the provided event storm into domains.

Designing the prompts to get DALL-E to do something extraordinary requires a new kind of technique that’s very different from understanding pigments and brushes. Machine language is reserved for a few people who need to work on some specialized areas of operating system internals, or who need to write some kinds of embedded systems code.

The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed.

Building on the Queue-Based Load Leveling Pattern , the Competing Consumer Pattern enables a system to process multiple messages concurrently to optimize throughput, to improve scalability and availability, and to balance the workload. To handle this fluctuating workload, the system can run multiple instances of the consumer service.

One of the biggest time costs in software development is understanding how a system works. Systems are getting more complex yet our ability to understand them doesn’t seem to be growing at the same rate. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it.

Technology systems are difficult to wrangle. Our systems grow in accidental complexity and complication over time. Architecture begins when someone has a nontrivial problem to be solved. The product management team states what must be done to solve the problem, and the architect describes how to realize that vision in a system.
