Mission-Critical Systems: Scaling, Migrating, Observing

In today’s data-driven world, modern businesses rely heavily on being able to trust their technical investments to keep up with the speed and scale they require, and deliver value without compromise.

Session 1: Onno Vos, Lead Engineer, Klarna.
Migrate your DB with confidence: Database migrations are hard. Performing them with zero down time can be even harder and some may even say they're impossible.

• How Klarna did the impossible - migrating a 15 TB Mnesia database to AWS Aurora with zero downtime.
• What are the most important steps in planning and executing a seamless large-scale database migration.
• Gain insights for confident and reliable system transitions.

Session 2: Behard Babbaee, Principle Solution Architect, Aerospike.
From the Front Lines: Solving Real-World Tech Challenges at PayPal, Snapchat, and BitcoinSV.

• Explore how attributes like performance, resilience, security, scalability, and cost-efficiency have shaped some of the world’s most demanding platforms.
• Draw on real engineering stories from PayPal, Snapchat, and BitcoinSV’s Teranode project
• Go behind the scenes to see how these systems met extreme demands.

Session 3: Harry Kimpel, Principal Developer Relations Engineer, New Relic.
Unlocking Observability: Leveraging OpenTelemetry to Trace Kafka Pipelines, Uncover Bottlenecks, and Illuminate Complex Streaming Architectures. In depth discussion surrounding:

• Trace data flows and detect bottlenecks with OpenTelemetry.
• Collect telemetry from Flink, Confluent, and other tools.
• Turn complex systems into transparent, observable architectures.

If you’re curious about the hidden forces behind high-stakes technology decisions, this talk is for you.

Networking: After the sessions pizza and beer will fuel further discussions with the hosts and your peers!
