Build on Serverless: Breaking the Monolith with Step Functions
Traditional monolithic architectures are hard to scale, and can become complex to update and maintain as the code base grows. The good news is that refactoring a monolith safely and easily is possible. Join AWS Solutions Architects Angela Wang and Ronald Widha Sunarno to see how. Angela and Ron will break a monolithic image processing application into multiple functions using AWS Step Functions.

Media Processing Workflows at High Velocity & Scale using Orchestration & Machine Learning
In this AWS Tech Talk, you’ll hear how AWS customers have improved media supply chains using machine learning in areas such as metadata tagging, translations, transcriptions, and cloud services. You’ll also learn how to use orchestration to optimize velocity and scale of multi-stage media pipelines by examining serverless, event-driven and artificial intelligence M&E use cases.
3 / 5
Using AWS Batch and AWS Step Functions to Design and Run High Throughput Workflows
AWS Batch enables developers, scientists, and engineers to easily and efficiently run hundreds of thousands of batch computing jobs on AWS. Learn how you can reliably orchestrate your batch workflow at scale using AWS Step Functions. This Tech Talk presents an architecture using AWS Batch and AWS Step Functions which fully manages the efficient provisioning of resources and the execution of your workflows.
4 / 5
Serverless Orchestration of AWS Step Functions
Are you building a serverless application with two or more Lambda functions? In this deep-dive session, learn how to use AWS CloudFormation and the AWS Serverless Application Model to deploy Step Functions state machines, AWS Lambda functions, and IAM roles and policies. We'll also demonstrate how Step Functions orchestrates state transitions and error handling, and how state input/output works.
5 / 5
Announcing AWS Step Functions
This short video gives you an introduction to AWS Step Functions, a reliable way to orchestrate your distributed applications. Hear how Step Functions automatically triggers and tracks each step, and retries when there are errors, so your application executes in order and as expected. You’ll also learn how Step Functions tracks the state of each step so you can diagnose and debug problems quickly.

Reference architectures
Long Lived Transactions
Learn how to use AWS Step Functions to manage the complexities of long lived transactions across distributed components in your microservices architecture. You will also use Step Functions to implement the Saga design pattern.
Media Analytics
This reference implementation provides guidance to consider when extracting metadata from media files, and provides a serverless AWS solution that combines Amazon Rekognition, Amazon Transcribe, and Amazon Comprehend.
Video on Demand
This solution illustrates best practices for implementing video-on-demand on AWS. AWS Lambda triggers AWS Step Functions for ingest, processing, and publishing workflows, and AWS Elemental MediaConvert performs transcoding.
Image processing and backend
Use AWS Step Functions to orchestrate a serverless processing workflow that processes photos uploaded to S3, extracts metadata from the image, uses image recognition to tag objects in the photo, and creates a photo thumbnail.
Batch for Life Sciences
This companion tutorial to the Genomics Workflows on AWS blog series packages bioinformatics applications using Docker, creates an AWS Batch environment for analysis, and deploys Step Functions to control data processing.
