• Every tenant must have its own role
• There hard account limits on roles
• Changes to the roles needs to be managed
• DynamoDB mapping isn’t as easy as AppSync’s direct
integration
Things To Be Aware Of

How I’ve Done It in the Past
EventBridge Lambda SDKs

Problems with This Approach
• Different than what you’re used to (CDK)
• Difficult to see what belongs to a tenant
• Updates are challenging

A Better Option
CDK S3 EventBridge Step Functions CloudFormation

Jason Wadsworth: Step Up Your SaaS Game: Serverless Orchestration and Automation for SaaS

What Didn’t Work with That Approach
• Didn’t allow for rolling deployments
• Multi-account, multi-region,
CloudFormation is complicated!

Another Way
CDK S3 EventBridge Step Functions CloudFormation
Account 1
CDK S3 EventBridge Step Functions CloudFormation
Account 2

Recap
• Step Functions can be used in tenant specific
workflows in a way that supports data protection
• Step Functions are a great way to manage tenant
specific resources with CDK and CloudFormation
• Managing tenant specific resources in a multi-account
system doesn’t have to be complicated

How to Build a Big Data Application: Serverless Editionecobold

Come learn how to build, launch, and scale a Big Data application in a serverless context. This is going to be an information packed meetup around Big Data processing, Lambda functions, Lambda Step functions, and everything that ties them together. Big Data is something we're very passionate about. As the cost of servers have come down and the cost of software has become free, using data to drive your business has become much more obtainable to a larger group of companies. The serverless methodology has recently come in the scene, and it's proving to be just as transformational as cloud has been to the Big Data analytics space. We will be sharing some of our learnings and experiences over the last two years of working with Big Data in a serverless context. We will cover one or two examples of eventful Big Data processing, and the impact it can have on your business in terms of speed of analytics and cost savings to the bottom line.

Serverless Design PatternsYan Cui

Serverless technologies like AWS Lambda has drastically simplified the task of building reactive systems - drop a file into S3 and a Lambda function would be triggered to process it, push an event into a Kinesis stream and magically it'll be processed by a Lambda function in real-time, you can even use Lambda to automate the process of auditing and securing your AWS account by automatically reacting to rule violations to your security policy. Join us in this talk to see some architectural design patterns that have emerged with AWS Lambda, and learn how to pick the right event source based on the tradeoffs you want. Amongst the many patterns we'll explore, here are a few to whet your appetite : pub-sub, cron, push-pull, saga and decoupled invocation.

AWS Lambda is a serverless compute service that runs code in response to events, automatically managing resources. It handles capacity, scaling, deployment, monitoring, logging, and security patching. Developers pay only for the compute time used to run their code, avoiding the need to provision and manage servers. Lambda functions can be triggered by events from services like API Gateway or S3 and are written in languages like Node.js, Python, Java, and C#.

Serverless applications allow developers to focus on writing code without worrying about managing infrastructure. With serverless, there is zero administration, no provisioning is needed, and applications can scale seamlessly. Some key benefits of the serverless approach are that it allows for rapid innovation and focusing on business value. Serverless uses building blocks like AWS API Gateway and AWS Lambda. API Gateway handles authorization and scaling for APIs, while Lambda allows code to be run in a serverless environment and scales automatically based on usage.

Event-driven architectures can help decouple services and simplify dependencies as your application grows. There are now new options for developers looking to benefit from this approach with the release of AWS Lambda controls for asynchronous and stream processing events, Lambda event destinations, and Amazon EventBridge, a serverless event bus service. In this tech talk, we'll demonstrate strategies for managing events to help you build more resilient event-driven applications. You will learn how to customize responses to Lambda function results with new service features to handle retries, failures, and prevent “poison pill” events. We will also demonstrate how to configure Lambda event destinations to route execution results to other AWS services, and how to set up routing rules in Amazon EventBridge that react to all of your data sources.

Design pattern talk by Kaya Weers - 2025 (v2)Kaya Weers

AI-proof your career by Olivier Vroom and David WIlliamsonUXPA Boston

This talk explores the evolving role of AI in UX design and the ongoing debate about whether AI might replace UX professionals. The discussion will explore how AI is shaping workflows, where human skills remain essential, and how designers can adapt. Attendees will gain insights into the ways AI can enhance creativity, streamline processes, and create new challenges for UX professionals. AI’s influence on UX is growing, from automating research analysis to generating design prototypes. While some believe AI could make most workers (including designers) obsolete, AI can also be seen as an enhancement rather than a replacement. This session, featuring two speakers, will examine both perspectives and provide practical ideas for integrating AI into design workflows, developing AI literacy, and staying adaptable as the field continues to change. The session will include a relatively long guided Q&A and discussion section, encouraging attendees to philosophize, share reflections, and explore open-ended questions about AI’s long-term impact on the UX profession.

Enterprise Integration Is Dead! Long Live AI-Driven Integration with Apache C...Markus Eisele

We keep hearing that “integration” is old news, with modern architectures and platforms promising frictionless connectivity. So, is enterprise integration really dead? Not exactly! In this session, we’ll talk about how AI-infused applications and tool-calling agents are redefining the concept of integration, especially when combined with the power of Apache Camel. We will discuss the the role of enterprise integration in an era where Large Language Models (LLMs) and agent-driven automation can interpret business needs, handle routing, and invoke Camel endpoints with minimal developer intervention. You will see how these AI-enabled systems help weave business data, applications, and services together giving us flexibility and freeing us from hardcoding boilerplate of integration flows. You’ll walk away with: An updated perspective on the future of “integration” in a world driven by AI, LLMs, and intelligent agents. Real-world examples of how tool-calling functionality can transform Camel routes into dynamic, adaptive workflows. Code examples how to merge AI capabilities with Apache Camel to deliver flexible, event-driven architectures at scale. Roadmap strategies for integrating LLM-powered agents into your enterprise, orchestrating services that previously demanded complex, rigid solutions. Join us to see why rumours of integration’s relevancy have been greatly exaggerated—and see first hand how Camel, powered by AI, is quietly reinventing how we connect the enterprise.
