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.

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.
