AWS S3 Overview

✍ π”Έπ•Žπ•Š π•ŠπŸ› Overview

Amazon S3 (Simple Storage Service) is a cloud storage service provided by Amazon Web Services (AWS). It is an object storage service that allows users to store and retrieve large amounts of data, such as files, images, videos, and backups, from any location with an internet connection. S3 is designed for durability and scalability, allowing users to store and access an unlimited amount of data at low cost.

S3 provides a simple web services interface, which enables developers to store and retrieve data using standard HTTP requests. Users can access their data using the S3 web interface, a command-line client, or through the AWS SDKs and APIs. S3 also supports a wide range of data management features, including versioning, lifecycle policies, and encryption. Additionally, S3 supports cross-region replication, which allows users to automatically replicate data to other AWS regions for added durability and disaster recovery.

S3 is used in a wide range of applications, including backup and disaster recovery, big data analytics, mobile and gaming applications, and content distribution. It also provides a storage layer for many other AWS services, such as Elastic Block Store (EBS), Elastic File System (EFS), and Glacier. S3 comes with multiple storage classes that are design for different needs, cost and performance. They are S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, S3 One Zone-IA and S3 Glacier.

✍ S3 Characteristics and Features

β‘  Amazon S3 is designed for 99.999999999% (11 9s) of data durability.

β‘‘ AWS aims to provide scalability, high availability, and low latency with high durability and availability.

β‘’ AWS launched S3 in the United States in March 2006, and Europe in November 2007

β‘£ Amazon S3 operates the scalable storage infrastructure that uses to run its e-commerce network.

β‘€ AWS S3 allowed choosing from supported checksum algorithms SHA-1, SHA-256, CRC32, or CRC32C.

β‘₯ Amazon declared that AWS S3 stored more than 100 trillion objects as of March 2021.

⑦ In 2017 AWS added default encryption capabilities at the bucket level.

✍ S3 Types

  1. S3 Intelligent-Tiering

  2. S3 Standard, S3 Standard-Infrequent Access (S3 Standard-IA)

  3. S3 One Zone-Infrequent Access (S3 One Zone-IA)

  4. S3 Glacier Instant Retrieval

  5. S3 Glacier Flexible Retrieval

  6. S3 Glacier Deep Archive

Note : πŸ“‚ Amazon S3 Standard is the default one.

✍ Best practices of AWS S3

There are several best practices for using Amazon S3 effectively:

  1. Use versioning: S3 versioning allows you to keep multiple versions of an object in the same bucket. This can be useful for data recovery and for maintaining a history of changes to your data.

  2. Use lifecycle policies: S3 lifecycle policies allow you to automatically transition objects to different storage classes or delete them entirely after a certain period of time. This can help you save money on storage costs and ensure that you are only paying for the storage that you actually need.

  3. Use encryption: S3 supports server-side encryption, which allows you to encrypt your data at rest. This can help protect your data from unauthorized access and ensure that it is protected while it is stored in S3.

  4. Use the appropriate storage class: S3 provides multiple storage classes that are designed for different use cases and have different performance and cost characteristics. It's important to choose the storage class that is most appropriate for your data based on your access patterns and budget.

  5. Use IAM Policies to control access: AWS Identity and Access Management (IAM) policies allow you to control who can access your S3 data, and what actions they can perform on that data. This can help ensure that your data is only accessed by authorized users and that it is protected from unauthorized access.

  6. Use CloudTrail to monitor access: AWS CloudTrail logs all S3 API calls, this will give you the ability to monitor and troubleshoot issues, it also helps to audit data access and to comply with regulatory requirements.

  7. Use CloudWatch to monitor performance: AWS CloudWatch allows you to monitor the performance of your S3 buckets, this will help you to identify any issues with your data, such as latency or high error rates, so you can take appropriate action.

Use S3 Transfer Acceleration: This feature of S3 allow you to accelerate uploads and downloads to and from S3 by using Amazon CloudFront's globally distributed edge locations. This can be particularly useful for large data transfers or for data transfers over long distances.
