Object Storage Classes:

Amazon S3 Standard (S3 Standard): S3 Standard offers high durability, availability, and performance object storage for frequently accessed data. Because it delivers low latency and high throughput, S3 Standard is appropriate for a wide variety of use cases, including cloud applications, dynamic websites, content distribution, mobile and gaming applications, and big data analytics.

Key features:

  • General purpose storage for frequently accessed data
  • Low latency and high throughput performance
  • Designed to deliver 99.99% availability with an availability SLA of 99.9%

Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering): often abbreviated as S3 Intelligent-Tiering, is a storage class introduced by Amazon Web Services (AWS) for their Simple Storage Service (S3). It is designed to automatically optimize storage costs by moving data between two access tiers: frequent access and infrequent access, based on usage patterns.

How S3 Intelligent-Tiering works:

  • Automatic Tiering: S3 Intelligent-Tiering automatically monitors the access patterns of your data and moves objects between two access tiers: frequent access and infrequent access. Data that is frequently accessed remains in the frequent access tier, while data that hasn’t been accessed for a period of time is moved to the infrequent access tier.

  • Cost Optimization: By automatically moving data between access tiers, S3 Intelligent-Tiering helps optimize storage costs. You don’t need to manually manage the movement of data between tiers, reducing operational overhead.

  • No Retrieval Fees: Unlike some other storage classes in S3, S3 Intelligent-Tiering does not incur retrieval fees when accessing data from the infrequent access tier. This makes it particularly cost-effective for data with unpredictable access patterns.

  • Durability and Availability: S3 Intelligent-Tiering provides the same high durability and availability as other S3 storage classes, ensuring that your data is protected against hardware failures and is accessible when needed.

  • Monitoring and Analytics: AWS provides tools for monitoring and analyzing the access patterns of your data stored in S3 Intelligent-Tiering. This allows you to gain insights into your data usage and make informed decisions about storage optimization.

Use S3 in which situation?

  • Data Backup and Archiving: S3 provides a reliable and cost-effective solution for storing backups and archives of data. Its high durability ensures that data remains safe over extended periods, making it ideal for long-term storage requirements.

  • Static Website Hosting: S3 can host static websites by storing HTML, CSS, JavaScript, and other web assets. It integrates seamlessly with other AWS services like Amazon Route 53 for DNS routing and Amazon CloudFront for content delivery, enabling fast and scalable website hosting.

  • Content Distribution: S3 combined with Amazon CloudFront allows you to distribute content globally with low latency and high transfer speeds. This is useful for delivering large files, streaming media, or website assets to users worldwide.

  • Application Data Storage: Many applications use S3 as a central storage repository for various types of data, such as user-generated content, media files, application logs, and configuration files. S3’s scalability and reliability make it suitable for storing large volumes of diverse data types.

  • Big Data Analytics: S3 serves as a data lake for storing vast amounts of structured and unstructured data that can be analyzed using AWS analytics services like Amazon Athena, Amazon Redshift Spectrum, or AWS Glue. Data stored in S3 can be queried directly without the need for data movement.

  • Disaster Recovery: S3 can be part of a disaster recovery strategy, where critical data backups are stored in S3 buckets across different AWS regions. In the event of a disaster, data can be quickly restored from S3 to maintain business continuity.

  • Data Warehousing: S3 can act as a staging area for data ingested into data warehouses like Amazon Redshift or Amazon Athena. Data is first loaded into S3 and then processed by the analytics services, allowing for scalable and cost-effective data storage.

  • Mobile and IoT Applications: S3 is often used as a storage backend for mobile and IoT applications to store user-generated content, sensor data, and application logs. Its scalability and compatibility with AWS SDKs make it easy to integrate with various application platforms.

2. Amazon EBS (Elastic Block Store):

Amazon Elastic Block Store (EBS) is a block-level storage service provided by Amazon Web Services (AWS) that is designed for use with Amazon EC2 (Elastic Compute Cloud) instances.

Block-Level Storage:

  • Amazon EBS provides block-level storage volumes that are similar to physical hard drives or SSDs, allowing users to create and attach storage volumes to EC2 instances.
  • These volumes appear as raw block devices to the EC2 instances and can be formatted and mounted like any other block storage device.

Persistence and Durability:

  • EBS volumes are designed for durability and reliability. Data stored on EBS volumes is replicated within the same Availability Zone to ensure data durability.
  • EBS volumes are persistent, meaning that data persists even after the associated EC2 instance is terminated. Users can detach EBS volumes from one EC2 instance and attach them to another without losing data.

High Performance:

  • EBS volumes offer high-performance storage options, including SSD-backed volumes (EBS-SSD) and magnetic volumes (EBS-HDD), to meet the performance requirements of different workloads.
  • SSD-backed volumes provide low-latency and high IOPS (Input/Output Operations Per Second) for performance-sensitive applications, while magnetic volumes offer cost-effective storage for less demanding workloads.

Snapshot and Backup:

  • EBS volumes support snapshots, which are point-in-time backups of the volume data stored in Amazon S3. Users can create snapshots of EBS volumes manually or automatically using scheduled snapshots.
  • Snapshots are incremental, meaning that only the changed blocks since the last snapshot are stored, which helps reduce storage costs and backup times.

Encryption and Security:

  • EBS volumes support encryption using AWS Key Management Service (KMS), allowing users to encrypt data at rest to meet compliance and security requirements.
  • Users can also specify encryption settings when creating new EBS volumes or encrypt existing volumes using snapshots.

Scalability and Flexibility:

  • EBS volumes can be resized dynamically without any downtime, allowing users to scale storage capacity based on changing workload requirements.
  • Users can choose from a range of volume types and sizes to meet the performance and capacity needs of their applications.

Integration with AWS Services

  • EBS volumes can be integrated with other AWS services such as Amazon EC2, Amazon RDS (Relational Database Service), and AWS Lambda to provide storage for various types of applications and workloads.

Use EBS in which situation?

  • Amazon Elastic Block Store (EBS) is used in various situations where persistent and scalable block storage is required for applications running on single Amazon EC2 instance

3. Amazon EFS (Elastic File System)

Amazon EFS is a scalable and fully managed file storage service designed to provide scalable and shared access to files from multiple EC2 instances. It supports NFS (Network File System) protocol and can be seamlessly integrated with existing applications and workflows.

EFS is suitable for use cases such as content management, media processing, software development, and data analytics that require shared file storage.

Use EFS in which situation?

Amazon EFS is commonly used in situations where multiple EC2 instances need shared access to a common file system. It provides a centralized and scalable storage solution for applications that require shared file storage
