The art of embracing failures

Nowadays serverless can mean many different things. Among others, it helps split bigger tasks into smaller pieces and run them in parallel, leveraging the power of distributed systems. It's also fun! And it's seemingly easy, almost magic-like! However, the real world is more nuanced than that. With all the power that distributed systems have given us, comes responsibility.In this talk, learn the most common challenges and pitfalls inherent to distributed systems and the ways to mitigate them. Delve into some real-world examples using two of the essential AWS serverless services: AWS Lambda and Amazon Kinesis. And most importantly, learn to embrace failures. Because as the CTO of Amazon Dr. Werner Vogels likes to say: everything fails, all the time.

Quash Your Quota: A Batching Pattern For Eventbridge Schedules

Scheduled tasks are a powerful tool for any service. A managed service like the one offered by AWS in the form of Eventbridge Scheduler opens the door to efficiently managing the scheduling of millions of tasks. But what happens when you have a high-traffic service that would see you reaching the quota limit for the service? A batching pattern can help alleviate at least some of the load. By consolidating event triggers and batching relevant updates together within a single schedule, you can effectively navigate quota issues without compromising the quality of your service. In this talk, I'll explore the triggers behind the need for a batching pattern, demonstrate its application, and unveil the profound impact it can have on your architecture and user experience. Discover how to leverage this approach for enhanced efficiency, scalability, and consumer satisfaction.

Why every Enterprise should build modular GenAI applications

Today it is easy to get blown away by all the newly released foundation models. Models can get outdated at a pace the AI industry has never seen before. But all models are associated with a cost, where the most powerful models usually have the highest price. This leads to the question, should we use the most powerful LLMs to solve all problems or should we use the best model for our use case ROI? Therefore, it has never been more important than now to build modular GenAI applications. In this session, we will focus on 1) the importance of building modular GenAI applications with AWS Bedrock as a core component 2) choosing the right model for the right task 3) showcase what a modular GenAI application can look like

Mastering AWS deployments with Terraform & Terragrunt

Terraform offers a robust, declarative way to describe your cloud infrastructure as code. And unlike some other IaC tools, Terraform also does a decent job comparing differences between your current version of IaC code, the last deployment stored in Terraform state, and the current state of the deployed cloud resources. But when it comes to managing and deploying multiple copies of the same infrastructure to same or different AWS account, an additional tool is needed. And that tool has the name Terragrunt. In this session, you will learn with a practical live demo, how to use Terragrunt to deploy Terraform code on a multi-account environment.

Empowering innovation through delegation: Novo Nordisk's user-centric AWS transformation

Embark on a journey with us as we chart the course of Novo Nordisk's transformative five-year adventure with AWS. Imagine the early days: AWS accounts in Novo Nordisk were created based a one-size-fits-all approach that tried to fit all AWS projects in the same box. The landing zone was being operated and maintained by a central team, and this was a great starting point for getting the company into AWS. But as our story unfolded, the plot thickened. Our other business units, driven by a thirst for innovation and a need for customization, began to construct their own platforms within this framework. They sought—and created—tailored accounts, each equipped with bespoke resources, ready to serve their distinct business narratives. It's time to turn the page to our latest chapter: the AWS delegated landing zone. Crafted with our users and stakeholders as co-authors, this revolutionary model redefines our cloud ecosystem, with users firmly at its heart. It's a tale of empowerment, where shared responsibility isn't just a concept, but a practiced creed, and trust and privileges are not just given, but dynamically delegated. In our presentation, we'll invite you behind the scenes of this ground-breaking approach. We'll dissect the anatomy of our delegated landing zone, revealing how it's poised to catapult our agility and adaptability to new heights. Join us for an insightful session that promises not just to tell, but to inspire your own cloud transformation narrative.

High performance Serverless Java on AWS

Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
