SageMarker
TO-DO
- Model Monitoring?
- Model Deployment
- Endpoints: Deploy trained models to fully managed endpoints for real-time predictions.
- Multi-Model Endpoints: Serve multiple models from a single endpoint, optimizing cost and management overhead.
- Serverless Inference: Deploy models without managing infrastructure, perfect for intermittent or unpredictable traffic patterns.
Machine learning workflow
Purpose:
- Specifically designed for machine learning (ML) workflows.
- Integrates deeply with SageMaker and other AWS ML services.
Features:
- Built-in ML Components: Pre-built steps for common ML tasks (e.g., data processing, training, model evaluation).
- Pipeline Structure: Define ML workflows using a series of steps, such as data preprocessing, training, and model deployment.
- Versioning: Tracks versions of pipelines, steps, and artifacts.
- Automation: Automates end-to-end ML workflows, from data ingestion to model deployment.
- Integration with SageMaker: Seamless integration with SageMaker's training, tuning, and hosting services.
- Optimization: Built to optimize ML-specific tasks, providing easy management and monitoring of ML experiments.
Example Use Case:
- Automating the entire ML lifecycle, including data preprocessing, model training, hyperparameter tuning, and deployment within the SageMaker environment.
AWS Step Functions
Purpose:
- General-purpose orchestration service for coordinating the components of distributed applications and microservices.
- Not limited to ML workflows.
Features:
- Flexibility: Can coordinate any AWS service, custom service, or third-party service.
- State Machines: Define workflows as state machines with states like Pass, Fail, Wait, Choice, Parallel, and Map.
- Error Handling: Built-in error handling, retry logic, and conditional branching.
- Integration: Integrates with a wide range of AWS services, including Lambda, ECS, DynamoDB, SNS, SQS, and more.
- Visual Workflow: Provides a visual interface to design and monitor workflows.
Example Use Case:
- Orchestrating complex workflows that might include data processing, invoking APIs, managing data pipelines, and integrating multiple AWS services.
Key Differences
Feature | SageMaker Pipelines | AWS Step Functions |
---|---|---|
Primary Focus | Machine Learning | General-purpose workflow orchestration |
Integration | Deep integration with SageMaker services | Broad integration across AWS services |
Pre-built Steps | ML-specific steps (e.g., training, tuning) | Generic steps for various use cases |
Workflow Definition | Step-based ML workflows | State machine-based workflows |
Error Handling & Branching | Basic support | Advanced error handling and conditional branching |
Versioning | Yes, with focus on ML artifacts | No inherent versioning for workflows |
Use Cases | End-to-end ML lifecycle automation | Orchestration of diverse applications and services |
Choosing the Right Tool
-
Use SageMaker Pipelines if:
- You are focused on building and automating ML workflows.
- You need tight integration with SageMaker's ML capabilities.
- You want built-in components for common ML tasks.
-
Use AWS Step Functions if:
- You need to orchestrate a variety of AWS services or custom services.
- Your workflow includes non-ML tasks or services.
- You require advanced workflow control with error handling and branching.
Both services can be used together in scenarios where you need the specific ML capabilities of SageMaker Pipelines within a broader application workflow managed by Step Functions.
