Study Notes

AWS Storage Services

AWS offers various storage services optimized for different data types and use cases.

Object Storage (Amazon S3)

Purpose: Designed for large-scale, unstructured data like images, backups, and videos.
Key Features: Highly scalable, secure, durable, accessed via internet or private network. Stores data as objects in buckets. Supports multiple storage classes.
Storage Classes:
- S3 Standard: General-purpose, frequently accessed data (websites, mobile apps).
- S3 Intelligent-Tiering: Automatically adjusts storage classes based on access patterns.
- S3 Standard-IA: Lower-cost storage for less frequent access, high-durability.
- S3 One Zone-IA: Stores data in a single Availability Zone (AZ), lower durability, suitable for non-critical data.
- S3 Glacier: Low-cost, long-term archival storage (compliance documents), retrieval in minutes to hours.
- S3 Glacier Deep Archive: Lowest cost, but longest retrieval time (12+ hours), best for seldom accessed data.
- S3 Outposts: S3 storage extends to on-premises AWS Outposts for fast local storage.

Block Storage (Amazon EBS)

Purpose: Ideal for databases, operating systems, and transactional workloads, requiring low-latency and high-performance.
Amazon EBS:
- Key Features: Persistent storage that survives instance termination, highly customizable performance (SSD, HDD), used with EC2 instances.
Instance Store:
- Key Features: Temporary storage directly attached to EC2 instances, data lost on instance stop or termination, high-speed, low-latency access, suitable for temporary data like caches.

File Storage (Amazon EFS/FSx)

Purpose: Shared storage accessible by multiple instances or users, supports hierarchical file systems.
Amazon EFS: Fully managed, scalable file storage for Linux-based workloads, supports multiple Availability Zones.
Amazon FSx:
- FSx for Windows File Server: File storage tailored for Windows-based applications, integrates with Active Directory.
- FSx for Lustre: High-performance storage for compute-intensive tasks like machine learning and big data analytics.

Cached File Systems (AWS Storage Gateway)

Purpose: Bridging on-premises applications with AWS cloud storage.
Key Features:
- File Gateway: Caches files locally, uploads to S3.
- Tape Gateway: Virtual tape library for backups.
- Volume Gateway: Presents cloud-backed iSCSI volumes to on-premises apps.

Lifecycle Policies

Purpose: Automate data movement between storage classes based on predefined rules (e.g., moving infrequently accessed data to lower-cost tiers). Reduces storage costs, simplifies management.

AWS Backup

Purpose: Centralized service for automating and managing backups of AWS services.
Supported Services: RDS, EBS, DynamoDB, EFS, and more.
Key Features: Centralized backup policy management, automated scheduling, supports encryption and retention policies, for disaster recovery, regulatory compliance.

Comparison of Services

Storage Type | Service | Best For
---|---|---
Object Storage | Amazon S3 | Large-scale data, backups, media
Block Storage | Amazon EBS | Persistent storage for EC2 instances
File Storage | Amazon EFS/FSx | Shared access, hierarchical file systems
Hybrid Storage | AWS Storage Gateway | On-premises to Cloud Storage integration

Real-World Scenarios

E-commerce Platform: Use S3 for product images, optimize costs with S3 Intelligent-Tiering.
Database Hosting: Use Amazon EBS with IOPS-optimized SSDs for database performance.
Media Processing: Use Amazon FSx for Lustre for speed in processing video files.
Backups: Use AWS Backup for managed backups across various services (e.g., RDS, EFS).

Key Takeaways

Amazon S3: Object storage, multiple storage classes for various access needs.
Amazon EBS: Block storage for EC2 instances.
Amazon EFS/FSx: File storage for applications (Linux/Windows).
Storage Gateway: Bridging on-premises and cloud storage.
AWS Backup: Automating backup management across AWS services.
