Study Notes
AWS Storage Services
- AWS offers different storage options/services:
- EBS (Elastic Block Store) - Block storage
- EFS (Elastic File System) / FSx - File storage (expensive)
- S3 (Simple Storage Service) - Object storage (cheap)
- File Cache
Amazon S3
- Amazon S3 is an object storage solution offering high levels of availability, durability, and scalability
- It handles over 100 trillion objects, averaging 100 million customer requests per second
- Request traffic peaks at over 950 TB/second globally
Object Store
- An object store is a flat file structure where data is stored as objects consisting of a globally unique identifier, metadata, and the data itself
- Each object's globally unique identifier (GUID) is also known as its key
- Object storage is useful for replicating data between development and production accounts and for compliance with data-residency laws
Amazon S3 Storage Classes
- S3 Standard for frequently accessed data
- S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data
- S3 Intelligent-Tiering for automatic cost savings for data with unknown or changing access patterns
- S3 Express One Zone for frequently accessed data
- S3 Glacier Instant Retrieval for archive data that needs immediate access
- S3 Glacier Flexible Retrieval for rarely accessed long-term data that does not require immediate access
- S3 Glacier Deep Archive for long-term archive and digital preservation with retrieval in hours at the lowest cost storage in the cloud
Archiving with Amazon S3 Glacier
- Amazon S3 Glacier is a low-cost, durable, and secure storage class for data archiving
- It allows reliable storage of any amount of data at cheaper costs
- Steps to use Amazon S3 Glacier:
- Create a bucket
- Enable "static website hosting"
- Edit Block Public Access settings
- Add a bucket policy that makes your bucket content publicly available
- Configure an index document
- Configure an error document (optional)
- Test your website endpoint
EBS and S3 Comparison
- EBS:
- Stores data as blocks
- Block size can be up to 16 tebibytes each (17.6 terabytes)
- Offers faster performance than AWS S3
- Data does not suffer loss, degradation, or corruption
- Data can be modified directly
- S3:
- Stores data as objects
- Individual object size can be up to 5,000 gigabytes (5 terabytes)
- Data can be modified only by re-uploading
Additional S3 Features
- S3 data protection/encryption
- Connecting on-premises storage to AWS with Amazon Storage Gateway
- Migrating large datasets to AWS with the AWS Snow Family
Key Points
- Amazon S3 offers a robust, scalable, durable, and cost-effective object storage solution in the cloud
- S3 Glacier provides three retrieval options for archiving data, with 99.999999999% durability
- Using S3 Glacier can reduce costs by 95% compared to S3 Standard
