Stop breaking stuff all the time!

Verifying behaviors of the cloud-native applications and ensuring that all of the services in the system work correctly together is both crucial and challenging. Manually maintaining environments to test the correctness of the entire system is undevops-like and fragile.

Luckily, modern tools can help you to build automated, reliable test pipelines, and in this session, Olga and Oleg explore how using Spring Cloud Contract and Testcontainers together can improve your testing and deployment processes.

DevOps revolutionised software development. It's time to revolutionise data.

The use of data analysis within a modern technology stack is at the core of a successful insurance business. Gjensidige, Norway’s largest insurance company, has recently begun it’s journey of moving all data operations from an on-prem data warehouse solution into the cloud. 

To succeed in this journey, we utilise the power of software best practices and DevOps culture: Product thinking, end-to-end responsibility, cross-team collaboration, and early problem solving. In this talk Alexandra will show how developers are a crucial resource to our success in publishing and maintaining high quality data products into our data platform by both growing and rooting DevOps culture and software best practices within our analyst teams.
