    our next webinar in the developer series: Learn more here: Improve your existing applications with serverless principles Inject new functionality into your existing application and reduce code complexity with serverless. In this webinar, we augment an existing, traditional, serverful application with serverless events, orchestration and integrations. We demonstrate how to ingest objects and data to trigger events, remove orchestration complexity with code, and integrate natively with AWS and third party services. Following the webinar, we get hands on with two workshops, allowing you to dive deep into event driven architectures and AWS StepFunctions. https://aws.amazon.com/ webinars/anz-webinar-series/
