Effective Microservices: Lessons Learned by Mark Richards

Microservices has been around for over a decade now. Over the years we’ve learned a lot, and have developed new practices, processes, techniques, and tools to wrangle this highly complicated architecture style. In this informative and entertaining session Mark Richards discusses the current state of microservices, including some of the lessons learned over the years. In the session he also talks about some of today's current techniques, tips, and practices to help maneuver around the complexity surrounding microservices.

Learning consistently with Bytesize Architecture Sessions by Andrea Magnorsky

Does your team suffer from: Inconsistent views of your systems? Producing incohesive solutions? Ineffective architecture practices and tools? Introducing Bytesize Architecture Sessions! Bytesize Sessions are a workshop format that enable collaborative and iterative knowledge sharing. This talk will inform you about how to run Bytesize Sessions resulting in the following benefits: improved systems thinking, enriching collaboration within the team, understanding architecture practices and tools in a safe environment, a feedback loop controlled by the team that produces better documentation across sessions, revealing the Bermuda Triangles!

A data-driven study of a large-scale micro component architecture Niklas Gustavsson

What does a large-scale micro component architecture look like in practice? In this talk we take a data-driven deep dive into Spotify’s 15 year old architecture. What patterns emerge across thousands of components (client features, services, data pipelines and websites) and their dependencies? By thorough instrumentation we collect data on what our architecture looks like in practice and can apply analysis on our software and social dependencies and measure how this class of architectures works at scale and speculate on how to scale them further.

Evolution Patterns of Sociotechnical Systems by Amal Tahri

Sociotechnical systems are nonlinear, dynamic systems that can exhibit complex and unpredictable behavior. These systems are constantly changing to provide value to customers, gain a competitive edge in the market or simply survive. Understanding the evolution patterns of sociotechnical systems is important to anticipate their behavior, designing improvement trajectory and managing change. In this talk, we explore evolution from real world use cases in its broadest scope, e.g., modernization, migration, adaptation, restructuring… We combine software evolution with the organization dynamics and people interactions to identify evolution patterns in sociotechnical systems. Finally, we study the impact of leadership and decision making on the success or failure of these cases.

Measurement as an Architectural Concern by Eoin Woods

Modern software engineering practices stress the need to optimise for learning throughout the software delivery process, which means that we need to create rapid feedback loops to allow this learning. Feedback loops work by allowing us to see how our work affects key measures such as quality, complexity, scalability, security, frequency of release, lead time, change failure rate and many other more specific measures for our individual situations. However the difficulty we often face is that it is difficult to measure many of the factors that we care about. This is often because we don't treat the ability to measure our systems as a requirement, but try to add measurement on-demand when needed. Would it not be better to treat measurement as an explicit architectural concern and incorporate it into our architecture practices? In this talk we will try to do just that, by examining what types of measurement we are likely to need, the techniques we can use to provide those types of measurement and how to incorporate consideration of measurement as an architectural concern into our work.

The Why & What of Observability in 2023 by Ben Evans

As applications move to containers and migrate to the cloud, they become ever more complex, and it's increasingly important to monitor, analyze, and diagnose their behaviour. Observability is a new way of thinking about monitoring and understanding your applications. It’s supported by a growing range of open source tools and standards - part of the new wave of technologies that modern developers need to go fully Cloud Native. Join Ben Evans to get the basics of Observability, including the fundamentals of metrics, logs, and tracing. You'll learn how to achieve observability using OpenTelemetry, the emerging Open Standard for Observability, and we'll meet several other related OSS libraries and tools along the way.
