Amazon Simple Storage Service Types

In my last article, i have covered about Network and Gateways which are essential for connectivity between On-Premise DC and AWS Cloud.

In this article, we will go through AWS Storage types which are the key factors in defining cost for cloud operations.

Common Parameters which are considered to select storage solution in any cloud or on premise are size, durability, availability, performance, and cost.

Different type of storage solutions which are available in AWS Cloud are: -

1.      S3-Standard

2.      S3 Intelligent-Tiering

3.      S3 Standard-Infrequent Access

4.      S3 One Zone-Infrequent Access

5.      S3 Glacier

6.      S3- Glacier deep archive

7.      Elastic File system (EFS)

8.      Elastic Block Storage (EBS)

Amazon S3 (Simple Storage Service) manage your data throughout its lifecycle. Once a S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application. S3 is distributed across 3 availability zones. Best for Static Websites and everything is stored as object.

Amazon S3 critical components (Bucket -keys, Prefixes and delimiters, Storage classes-Lifecycle management, Versioning, MFA, Object locks)

1.S3-Standard- It is used for general-purpose storage of frequently accessed data. Low latency and high throughput performance.

Durability of 99.999999999% of objects across multiple Availability Zones.

Availability 99.99% over a given year.

SSL for data in transit and encryption of data at rest.

It supports S3 Lifecycle management for automatic migration of objects to other S3 Storage Classes.

2.S3-Intelligent Tiering- It is used for Long-lived data with changing or unknown access patterns.

Latency, Performance, Durability is similar to S3 standard storage but Availability 99.9 %.

Automatically moves objects between two access tiers based on changing access patterns. Additional monthly monitoring and auto-tiering fee.

3.S3 Standard-Infrequent Access- It is used for long-lived, but less frequently accessed data.

4.S3 One Zone-Infrequent Access- It stores data in single availability zone and ideal for customers who want a lower-cost option for infrequently accessed data as well as no requirement of the availability and resilience of S3 Standard or S3 Standard-IA.

5.Amazon S3 Glacier (S3 Glacier)- It is used for long-term archive and digital preservation. Amazon S3 Glacier is an extremely low-cost storage service that provides secure, durable, and flexible storage for data backup and archival. Configurable retrieval times, from minutes to hours. S3 PUT API for direct uploads to S3 Glacier, and S3 Lifecycle management for automatic migration of objects.

Access Methods retrieval options-(Expedited 3-5minutes, Standard 3-5 hours, Bulk 5-12 hour)

Critical terms in S3 Glacier-Vault for archives in Glacier, Vault locks.

A single account can create 1000 vaults in a region.

6.Amazon S3 Glacier Deep Archive- Lowest cost storage class designed for long-term retention of data that will be retained for 7-10 years. Ideal alternative to magnetic tape libraries.

Retrieval time within 12 hours.

S3 PUT API for direct uploads to S3 Glacier Deep Archive, and S3 Lifecycle management for automatic migration of objects.

7. Amazon Elastic File System (EFS)- Managed File Storage for EC2. It is Scalable, elastic, cloud native NFS file system.

8.Elastic Block Storage- High Performance Storage, Persistent Storage.

Types of EBS are -Magnetic, SSD, General Purpose, Provisioned iops.
