Mapping ISO 27001 to Modern Software Engineering: Secure by Design

In today's increasingly complex digital landscape, security is no longer an afterthought but a foundational pillar of software engineering. Achieving ISO 27001 certification has become essential for many organizations striving to build trust, minimize risks, and ensure regulatory compliance. In this talk, we will explore why this certification is so crucial for software companies and delve into the specifics of ISO 27001 controls (especially clause A.8) that focus on secure development. We will map these security requirements onto a modern Software Development Lifecycle (SDLC), highlighting practical approaches that integrate nicely with agile frameworks and DevOps principles.

Furthermore, we will explore a range of tools, such as static analysis software, dependency scanners, automated deployment checks and many more to effectively meet ISO standards. We will also discuss how to adopt and integrate OWASP SAMM (Software Assurance Maturity Model) into the development process as a way to continuously assess and improve the security posture of your projects, ensuring that security becomes a continuous, iterative effort within your teams and your organization.

Java-Powered AI on Kubernetes: From Development to Deployment with Ease

Are you a Java developer eager to explore AI but unsure where to begin? In this session, we’ll guide you through building and deploying AI applications in Java, leveraging familiar tools and running them effortlessly on Kubernetes. We’ll start by showcasing how Quarkus and LangChain4J simplify the development of AI-driven applications, making advanced use cases more accessible than ever.

Next, we'll address the challenge of running AI models for inference at scale using the Ollama operator, a lightweight yet robust solution for managing model serving on Kubernetes. In addition, we’ll dive into why vector databases are critical for many AI workloads and how these can serve as a high-performance storage and retrieval system for your data.

Join us for a live demo where we’ll walk through building and running a real-world AI use case on Kubernetes, demonstrating the tools and best practices you need to succeed. Whether you’re just starting with AI or looking to optimise your current workflows, this talk will equip you with practical insights to accelerate your AI journey in Java.

Continuous API Mocking and Testing with Microcks, Keptn, and Testkube

In dynamic API development, efficiency and reliability are critical. This talk introduces three powerful cloud-native frameworks: Microcks, Keptn and Testkube.

Microcks enables automated API mocking and testing in a Kubernetes-native environment, supporting various API standards such as REST, gRPC, and GraphQL. Keptn provides event-driven orchestration for testing and QA, ensuring smooth API deployments. Testkube provides a flexible test execution environment for Kubernetes, allowing API tests to be triggered based on events. We will demonstrate how these tools accelerate API development, increase cloud-native software delivery agility, and ensure robust, standards-compliant, and well-tested APIs.

Architecting and Building a K8s-based AI Platform

Developing a scalable and production-ready AI platform poses significant challenges for organisations. Beyond a modular and flexible architecture, critical aspects such as infrastructure automation, orchestration, model deployment, and lifecycle management must be efficiently addressed. Kubernetes and open-source technologies provide a powerful foundation for tackling these challenges.

In this talk, we will explore the conceptual architecture and blueprint of a cloud-native AI platform, outlining the key design principles and best practices that enable scalability, automation, and reproducibility. We will then demonstrate how to build this platform step by step - both locally and in the public cloud - leveraging Kubernetes, open-source tools, and GitOps. The focus will be on creating a highly automated, repeatable, and production-ready environment for machine learning and AI workloads.
