How to reduce the footprint of Spring Boot applications
How to reduce the footprint of Spring Boot applications

In this session we will walk through various techniques to significantly reduce the resource consumption of regular Spring Boot applications, including using Spring AOT for regular Spring apps, compiling Spring Boot apps to native images (using GraalVM), and using CRaC for instant startup (for scale-to-zero scenarios). We will compare the different approaches, discuss pros and cons for each technology, and share concrete numbers from real-world applications to give the audience an idea of what can be achieved using these technologies.

Target Audience: Developers, Architects
Prerequisites: Basic Spring Boot knowledge required
Level: Advanced

The tragedy of user-centred design
The tragedy of user-centred design

User-centred design is one of the default modes of teams working with software, but the consequences are often unsustainable in a densely networked world as we privilege users over all other stakeholders and systems. How might teams approach building products, services and organisations from a more sustainable standpoint than 'user-centricity'? This talk looks at how the techniques of game design, community development, platform operations and security practices can support a practice focused on hyperobjects for multi-centric design.

Target Audience: Leaders, Builders, Architects, Designers, Community Members
Prerequisites: No previous knowledge, only enthusiasm for systems, building things and design
Level: Advanced

Extended Abstract:
The key feature of a 'tragedy' is when everybody does the right thing but it goes wrong anyway. The aim of this session will be to look at why user-centred design goes wrong even if everyone's intentions are pure. This talk (gently!) brings in ideas from feminism, design thinkers, political science and anthropology to focus on very practical, grounded approaches to sustainable design in software teams. We'll look at how building things and designing organisations that have increased levels of friction can improve users' experience and how 'seamless' design can lead to disempowerment. And we'll also draw on the speaker's practical experience of building products used by millions of citizens as part of the UK's digital transformation. By the end of the session we'll have a sense of what might replace the shallow seamlessness of 'user-centred' design — a multi-centric, transcendental design aimed at manufacturing enthusiastic consent.

Simon Edward Bostock is a product and design leader who's worked with software for 20+ years. His interests include how firms and brands incorporate new technologies, how work flows through organisations, EverythingOps and service topologies.

We shrink the cloud – CO2 consumption as DevOps team KPI
We shrink the cloud – CO2 consumption as DevOps team KPI

At Tchibo we wanted to reduce our server and energy consumption with our product development teams. But why would we care? We all like fast snappy development and test systems. And our shop needs to survive Black Friday’s shopping traffic. Annual Google Cloud consumption forecasts do not trigger us to consume less. But when we started to show teams their related carbon dioxide footprint, we created a feedback loop that will help us to become better CO2-developers.
As developers, we have an impact - to program CO2 reduction.

Target Audience: Everyone, Developers, DevOps People
Prerequisites: None
Level: Advanced

Extended Abstract:
We will present the idea and first measurements on the server side. The planned client side measurements are still work in progress and very difficult to perform. Nevertheless is the client side induced CO2 consumption at large websites probably a large lever for reduction.
