Challenges of using Private AppSync for 1100 Parcel Lockers accross The Netherlands

Room: Zaal 14 | Time: 11:00 | Duration: 30

In 2024 and begin 2025 we’ve migrated the Embedded and Cloud application behind 1100 Parcel Locker Machines in The Netherlands at PostNL. Let me take you through the challenges and lessons we’ve learned replacing and migrating the cloud application where 1100+ (adding 500 more this year!) connect to. From why we had to do this, the mistakes we made, the lessons we’ve learned and improvements that are happening. Processing over 120.

Guarding the Generative Path: Architecting Responsible AI with Amazon Bedrock Guardrails

Room: Zaal 8 | Time: 11:00 | Duration: 30

Generative AI can accelerate innovation, but only when every response respects safety, privacy and trust. In this session, we step inside Amazon Bedrock Guardrails and see how purpose-built safeguards turn risky prompts, hallucinations and policy violations into confident, production-ready answers. Let’s explore how versioned “guardrails-as-code” enables a single CloudFormation push to raise the safety bar without touching app logic, with real-time metrics and audit logs streaming straight into CloudWatch to spotlight every blocked prompt the moment it happens.

Modern Logging on AWS: Real-World Strategies for Developer Efficiency (Talks and quizzes session)

Room: Zaal 10 | Time: 11:00 | Duration: 30

Logging often gets ignored—until something breaks. But it can be a powerful tool for debugging, improving visibility, and keeping costs in check. In this session, we’ll explore how to build and manage logging systems on AWS using services like Amazon CloudWatch, Amazon OpenSearch, and Grafana. You’ll see practical examples, compare different approaches, and walk away with a clear understanding of how to create a logging design that’s fast, scalable, so you can catch issues earlier and solve them faster.

Simplifying Serverless Integration Testing: WireMock on AWS Lambda

Room: Zaal 11 | Time: 11:00 | Duration: 30

In serverless architectures, integration testing becomes a key focus in the testing pyramid, as local environments cannot fully replicate the complexities of cloud deployments. External APIs, often unavailable or difficult to configure, pose a significant challenge during testing. Mocking external APIs locally with tools like WireMock is common, but to truly validate serverless applications, testing must occur in the deployed environment. This talk explores how to leverage WireMock on AWS Lambda to mock external APIs directly in the cloud.

Your AWS root credential set

Room: Zaal 9 | Time: 11:00 | Duration: 30

Is it secret? Is it safe? Managing the one credential set to rule them all comes with a considerable amount of effort. Even worse, AWS provides APIs to effectively privilege escalate a normal AWS admin role/user to root. What paths can a hacker take to completely takeover your AWS account, or even organization, and what mechanisms can you implement to combat this?
