Week 4 Agenda: Core Storage Services and Concepts

Week 4 Objectives

  • Understand how Amazon S3 works as a global-scale object storage service.
  • Learn how to manage access to S3 using Access Points, Bucket Policies, IAM, and CORS.
  • Explore S3 Storage Classes, including lifecycle transitions and cost optimization.
  • Practice setting up S3 Static Websites, configuring CORS, and tuning for performance with object key design.
  • Learn how to archive and retrieve long-term data using S3 Glacier and its retrieval tiers.
  • Understand hybrid storage solutions: Snow Family for data transfer appliances and Storage Gateway for on-premise integration.
  • Gain basic familiarity with AWS Backup for centralized, automated backup management across services.

Week 4 Achievements

  • Understood S3 Object Storage Architecture:

    • Learned how buckets and objects are globally accessible via unique URLs.
    • Understood S3’s strong read-after-write consistency and distributed design.
    • Explored Access Points for simplified and controlled data access at scale.

  • Gained Insight into S3 Storage Classes:

    • Compared the cost, durability, and retrieval times across classes (Standard, IA, One Zone, Intelligent Tiering, Glacier family).
    • Designed lifecycle rules for automatic transitions and deletion.
    • Understood scenarios for using archival storage.

  • Configured S3 Static Hosting and CORS:

    • Set up website indexing, error pages, and public access settings.
    • Configured CORS for cross-origin requests from web applications.
    • Understood the security risks of misconfigured public access.

  • Learned about Key Naming, Performance, and Data Management:

    • Studied S3’s request parallelism and the effect of key distribution.
    • Practiced multipart uploads for large files.
    • Configured object versioning and replication (CRR/SRR).

  • Explored Glacier and Long-Term Archival:

    • Created archives and retrieval requests across different retrieval tiers.
    • Understood the use cases for cold, infrequent, and deep archive storage.

  • Understood Hybrid Storage Services:

    • Learned about Snowcone, Snowball, Snowmobile and their roles in bulk data transfer.
    • Explored Storage Gateway for bridging on-prem systems with cloud storage using file, volume, or tape interfaces.
    • Gained basic knowledge of AWS Backup for automated policy-based backups across AWS services.

  • Developed a solid understanding of how object, archival, and hybrid storage fit together in AWS, creating the foundation for scalable, cost-efficient, and secure data management.
