Abstract
Distributed data-intensive systems are increasingly designed to be only eventually consistent. Persistent data is no longer processed with serialized and transactional access, exposing applications to a range of potential consistency and concurrency anomalies that need to be handled by the application itself. Controlling concurrent data access in monolithic systems is already challenging, but the problem is exacerbated in distributed systems. To make it worse, only little systematic engineering guidance is provided by the software architecture community regarding this issue.
Susanne shares her experiences from different case studies with industry clients, and novel open access design guidelines developed using action research. In this talk you will learn settled and novel approaches to tackle consistency- and concurrency related design challenges.
Topics
QCon London 2023 is a three day conference for senior software engineers, architects and team leads. An international program committee of working engineers selects every session. Patterns and practices, not products and pitches.

10:35 Fleming (3rd Fl.) Session consistency Eventual Consistency – Don’t Be Afraid! Susanne Braun Principal Tech Lead @SAPSignavio Distributed data-intensive systems are increasingly designed to be only eventually consistent. 11:50 Fleming (3rd Fl.) Session cloud native The Commoditization of the Software Stack: How Application-first Cloud Services are Changing the Game Bilgin Ibryam Principal Product Manager @Diagrid, Co-author of “Kubernetes Patterns“, Previously Architect @RedHat The runtime boundaries between applications and the cloud are shifting from virtual machines to containers and functions. The integration boundaries are moving away from pure data access to one where the mechanical parts of the application are running within the cloud. 13:40 Rutherford (4th Fl.) Unconference Unconference: Building Modern Backends Shane Hastie Global Delivery Lead @SoftEd, Lead Editor for Culture & Methods @InfoQ What is an unconference? An unconference is a participant-driven meeting. Attendees come together, bringing their challenges and relying on the experience and know-how of their peers for solutions. 14:55 Churchill (Ground Fl.) Session OpenTelemetry Effective and Efficient Observability with OpenTelemetry Daniel Gomez Blanco Principal Engineer @Skyscanner Modern architectures require effective observability solutions to be able to monitor their health and understand how system changes affect operations distributed across multiple services. 16:10 Fleming (3rd Fl.) Session api Connecting the Dots: API Design in a Distributed World Ben Gamble Adviser, Architect & Speaker About Interactive Technology, Startups & Event Driven Systems As we’ve gone from building monoliths to building microservices, the number of APIs we’ve got to manage has gone from just the database and front end, to at least one per service. 17:25 Churchill (Ground Fl.) Session Data What is Derived Data? (And do You Already Have Any?) Felix GV Principal Staff Engineer @LinkedIn There is a growing trend of databases specializing in derived data ingestion and serving. They complement more traditional “primary data” (or “source of truth”) systems.
