Overview
How it works
These technical details feature an architecture diagram to illustrate how to effectively use this solution. The architecture diagram shows the key components and their interactions, providing an overview of the architecture's structure and functionality step-by-step.
Well-Architected Pillars
The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.
Operational Excellence
Step Functions orchestrates Lambda, MediaConvert, and Amazon S3 workflows. The Step Functions console graph view provides a graphical representation of your state machine with visual indications of which steps have succeeded, are in progress, have failed, have caught error, or were cancelled. Visualizing the status of Step Functions states helps the operator understand workflow health.
Security
All user data stored in DynamoDB is fully encrypted at rest. DynamoDB encrypts your data at rest using encryption keys stored in AWS Key Management Service (AWS KMS), which helps reduce the operational burden and complexity involved in protecting sensitive data. All AWS Identity and Access Management (IAM) policies have been scoped down to the minimum permissions required for the service to function properly. Minimum permissions set by IAM help you avoid unauthorized access.
Reliability
Lambda supports automatic scaling to handle increased workloads and runs in multiple Availability Zones to help ensure that it is available to process events in case of a service interruption in a single Availability Zone. Lambda supports automatic scaling, retries, and high availability, adding resiliency and reliability to the workflow. DynamoDB automatically replicates data across multiple Availability Zones, offering high data durability and integrated availability.
Performance Efficiency
Serverless architectures that use serverless managed services like Lambda remove the need to run and maintain physical servers for video or image processing workflows. As a managed service that hosts code, Lambda can also lower transactional costs because managed services operate at scale in the cloud.
Cost Optimization
The Amazon S3 Intelligent-Tiering storage class optimizes storage costs by automatically moving data to the most cost-effective access tier when access patterns change. This reduces storage cost of the content that is not regularly accessed.
Sustainability
Step Functions is a managed service that scales based on demand, so you do not have to manage underlying infrastructure. This reduces carbon emissions as Step Functions has inherited compute efficiencies and only runs when needed. Additionally, Step Functions provide an event-driven architecture for the Product Catalog Creation and Video and Image Analysis and Processing pipelines, which, in combination with Lambda only consume computational resources when actually processing data. These pipelines scale on demand to avoid over-provisioned server capacity.
