Muhammad Sumon Molla Selim : Building Zero-trust architectures inside Amazon EKS

"As cloud-native architectures scale, the traditional network perimeter no longer exists. Kubernetes clusters on AWS — whether single or multi-tenant — demand a new approach to security: Zero Trust. In this session, we’ll explore how to build a Zero Trust architecture inside Amazon EKS, focusing on workload identity, authentication, authorization, and encryption across services."

Pubudu Jayawardana : Better isolation for your SaaS tenants with Lambda tenant isolation

"In a multi-tenant SaaS application, tenant isolation is one of the most challenging problems to solve correctly. If you need strong isolation, a single-tenant approach might be the best option, but it comes with its own operational and scalability trade-offs. In this talk, I will explore AWS Lambda's latest security feature, Tenant Isolation, and how it helps you to maintain a multi-tenant architecture while achieving stronger isolation boundaries with reduced complexity."

Summary of the talks

Talk 1: In this talk, we’ll walk through how Rabobank designs for failure using AWS Backup: from automated policies and immutable vaults to restore testing and ransomware protection. Because resilience isn’t just about having backups—it’s about knowing they work.

Talk 2: What happens after an innovation delivers a promising platform before it’s ready for enterprise scale, governance, and speed? That’s where our journey begins. You’ll hear how we evolved the architecture to support over 100 microservices powering digital lending on a compliant-by-design AWS environment. We’ll share the decisions we made along the way: what we kept and what we changed. Central to our approach is Infrastructure as Code to enable consistency, repeatability, and control on the platform. We’ll show how this foundation helped us automate operations, accelerate delivery, and meet strict compliance requirements. Join us to learn how to bridge the gap between innovation and enterprise readiness, turning a promising start into a scalable, secure, and developer-friendly platform.

Talk 3: EDSN acts as the digital backbone of the energy market, supporting essential data exchange processes across the energy market value chain. We explore this role, the underlying IT foundation, and the challenges and trade-offs that come with it.
