Location: King's Suite - Balmoral Level: Advanced
Secondary topics:  Best Practice, Case Study

Who is this presentation for?

Architects, developers (senior), enterprise architects

Prerequisite knowledge

- Hands-on experience with software architecture in a landscape consisting of multiple applications - Some experience with project management for teams working on such a landscape

What you'll learn

- Realize how technical communication between systems in a landscape will influence communication between teams. - Get ideas on how such communication can be improved. - Get ideas on measurements that can be used to locate the bottlenecks. - Hear about case studies where large architectures were changed to better facilitate communication.


In recent years, software has become a lot more interconnected. Functionality is no longer delivered by monolithic systems, but by smaller systems and components that exchange data and communicate with each other. Developments like microservice architectures mean the notion of what can be considered a “system” is becoming both less clear and less relevant.

However, most teams applying software quality techniques still primarily focus on individual systems. While this is great to ensure the system remains maintainable and flexible, it would also be useful to focus on the maintainability of the landscape as a whole. The way the communication between systems is implemented influences the flexibility at which those systems can be changed. Moreover, it also determines the way the teams working on those systems will communicate with each other.

In this talk, we discuss how we can measure the maintainability of software landscapes that consist of many systems communicating with each other, and what that means for the teams working on them. We will also explore a number of trade-offs that teams will need to consider when designing the landscape, and explore some best practices for modern software landscape architectures.
