Till likes to build simple solutions to solve customer problems, working on data modeling, analytics and exploring new technologies. 𝗦𝗲𝘀𝘀𝗶𝗼𝗻 𝗧𝗶𝘁𝗹𝗲: Measuring and increasing resiliency through Chaos Engineering 𝗦𝘆𝗻𝗼𝗽𝘀𝗶𝘀: Building and operating resilient applications requires deep understanding of your system in its normal and in failure states. Chaos engineering is an approach to build confidence in system resilience by deliberately injecting faults or stress to identify and fix problems before they wake you up at 3am. You will learn the core concepts of chaos engineering and what you need to implement them: gaining understanding of normal operations, building hypotheses how your system handles faults and injecting failures trying to disprove the hypothesis. We will dive into how you can observe steady state, design experiments to uncover weaknesses, follow-up on experiments & how to design resilient architectures. The talk provides a hands-on introduction to chaos engineering through actionable techniques you can start applying in your organization.

Marcel Hild
Señor Manager OpenShift
Black Belt, EMEA, Germany
Marcel Hild has 25+ years of experience in open-source development and the IT industry. He co-founded a Linux consulting company, worked as a Solution Architect for Red Hat, and was a core Developer for ManageIQ, a Hybrid Cloud Management tool. In addition, he researched AIOps and Open Services in the Office of CTO at Red Hat and built a community of SRE practitioners around operate-first.cloud. Now he practices the fine art of managed-OpenShift-Black-Belt-Do with customers and partners to leverage a managed platform to put his previous research topics into real life. 𝗦𝗲𝘀𝘀𝗶𝗼𝗻 𝗧𝗶𝘁𝗹𝗲: Managing Kubernetes clusters at scale - behind the scenes of managed OpenShift 𝗦𝘆𝗻𝗼𝗽𝘀𝗶𝘀: In this session, Marcel Hild will navigate the attendees through the complex landscape of managed cloud services, focusing specifically on managed Kubernetes clusters. Although they are fundamentally rooted in open-source, the internal machinations and operational environments of these services often remain shrouded. Using only publicly accessible information, we will demystify the methods and tools that underpin the management of sprawling OpenShift clusters. The discussion initiates with a detailed overview of architectural principles, progressively venturing into the nuanced terrain of cloud-native tooling. After this session, you will understand the depth of open-source integration within managed services and the pivotal role it plays in fostering an environment for contribution and reusability. Attendees will depart with a comprehensive understanding of the architecture and operational mechanisms that form the backbone of large-scale OpenShift cluster management. Furthermore, they will gain valuable insights into the cloud-native tools landscape, comprehending how it profoundly influences the operation of managed services. Join this session to learn more about open source in managed services and how much it enables reuse and contribution.

𝗦𝗲𝘀𝘀𝗶𝗼𝗻 𝗧𝗶𝘁𝗹𝗲: Managing Technical Projects like a Pro: Lessons from a Solo SCM Migration 𝗦𝘆𝗻𝗼𝗽𝘀𝗶𝘀: Writing code is something that we learned. Managing a project E2E - Probably not that much. Nevertheless, we have them in our professional day-to-day, all the time – Introducing new features, migrations, and more. So how can we handle them in a way that will enable us to run fast, independently, while meeting the necessary deadlines? In this talk, I will share my journey of migrating an entire R&D’s code base from BitBucket cloud to a self-hosted GitLab on my own (But in collaboration with people from cross teams) - Planning, implementation, and handoffs. I’ll share best practices for managing a technical project with a lot of takeaways you could adopt so your project, any technical project, will be handled smoothly and successfully.

Daniel Iliescu
Director, Software Engineering, EAIT
Daniel leads a team of passionate software engineers in Electronic Arts to build the next gen Game Developer Platform. In the past 20 years, Daniel has also led software engineering teams in other industries such as the financial industry to build diverse enterprise scale software products, from electronic channels to data warehousing and analytics. He has a background in software engineering, specialising in .NET development as well as product and project management. 𝗦𝗲𝘀𝘀𝗶𝗼𝗻 𝗧𝗶𝘁𝗹𝗲: Using the power of the cloud to support Game Development at Scale 𝗦𝘆𝗻𝗼𝗽𝘀𝗶𝘀: Traditionally, game development is a process heavily reliant on powerful bare-metal infrastructure with high demands on GPU and CPU processing. In this day and age, scaling physical infrastructure hit its limits and stressed the hardware supply chains that cannot satisfy demands anymore. This team believes that cloud technologies can augment and even replace existing infrastructure, to provide game creators with a performant and scalable platform to develop some of the best games in the industry. We will dive into their journey to prove out how games can be developed from anywhere in the world in the cloud, in a secure, reliable and scalable fashion. Maybe even more importantly, we will also explore how cloud and infrastructure-as-code can be used to enable workflows and processes that would have never been able to be performed with traditional infrastructure.
