From Fragile to Flexible: Migrating to AWS Account Factory for Terraform:
Managing hundreds of AWS accounts is no small task—especially when the tooling behind it is brittle and officially unsupported. In this session, you’ll hear how SOK AWS Platform team is migrating from an aging deployment platform to AWS Account Factory for Terraform (AFT), the modern, officially supported way to manage AWS accounts at scale.

Session will cover the journey of importing existing accounts from CloudFormation into Terraform, lessons learned along the way, and how AFT helps to improve consistency, automation, and long-term maintainability. You'll walk away with practical insights into AFT, migration patterns, and pitfalls to avoid.

Ari Luokkala:
Ari is a Principal Cloud Engineer at SOK, based in Helsinki. He works in the SOK AWS Platform team, where they focus on platform development and collaborate closely with development teams.

He’s passionate about cloud technology, driven by curiosity, and a strong believer in continuous learning. Outside of work, you'll most often find him enjoying sports or fishing.

Markus Toivakka:
Markus is a hands-on Cloud Architect at the SOK AWS Platform Team. Once a strong advocate of CloudFormation over Terraform (those days are gone), he since has gathered plenty of experience from managing multi-account AWS environments that he’s excited to share.

Throttling to Thriving:
When large amounts of data hit DynamoDB, throttling can leave items unprocessed. This session introduces a simple yet effective retry strategy using exponential backoff algorithm to manage traffic smoothly. Discover how to prevent overload, handle spikes gracefully, and maintain a stable, reliable system for high-volume data provisioning.

Junsheng Tan:
Junsheng is a Lead Software Developer and Scrum Master at KONE, where he builds software for large-scale, globally distributed systems. He is an advocate and contributor to Cloud Technologies and AI within KONE, with experience in project management, software architecture, and AI development. Outside of work, he enjoys scuba diving in summer and skiing in winter.

RSVPs open 14.9.2025 at noon.
