What Is Amazon S3?

Amazon Simple Storage Service (AWS S3) is a scalable, high-speed, low-cost, and fully managed object storage service provided by Amazon Web Services (AWS). S3 provides customers with secure and durable storage of their data in the form of objects, which are organized into buckets, and can be accessed through APIs and web-based interfaces.

It is used by businesses of all sizes to store and manage large amounts of data, including images, videos, backups, and other forms of data.

What Is an Amazon S3 Bucket?

S3 in Amazon has two primary entities called buckets and objects. Objects are stored inside buckets. Also, it does have a flat hierarchy, not like the one you would find in a file system.

But in an organization, a file system is needed in an ordered fashion, and that’s why AWS S3 introduced a file system that seems like a traditional one.

AWS S3 bucket is a cloud-based data storage service offered by Amazon Web Services (AWS). It provides an unlimited amount of scalable, durable, and secure storage for data, allowing organizations and individuals to store large amounts of data in the cloud.

S3 buckets can be used for a variety of purposes, including file storage, backup and archiving big data analytics, and content distribution. 

The buckets are easily accessible from anywhere in the world, making it simple to store, access, and manage data on the cloud. S3 also provides a number of features that make it easy to manage and organize data, such as versioning, lifecycle policies, and access controls.

Additionally, S3 integrates with a number of other AWS services, providing users with a seamless experience for storing and managing data in the cloud. With its reliability, scalability, and security, the S3 bucket is an ideal solution for organizations of all sizes looking to store and manage data in the cloud.

Amazon S3 Concepts

Now that you know what is Amazon S3 and what is Amazon S3 bucket, let’s move on and discuss some basic Amazon S3 concepts starting from Data Consistency Models.

Data Consistency Models

S3 in Amazon provides amazing highly available and durable storage solutions by replicating the data under one bucket in multiple data centers in the region. Also, the data uploaded to an Amazon S3 bucket never leave it until you delete it.

S3 has 2 types in the consistency models:

  • read-after-write consistency
  • Eventual consistency

Read-after-write consistency for PUTS of new objects in your S3 bucket in all the regions with one limitation. The limitation is that if you perform a GET or HEAD for an object which does not exist then first eventual consistency will be provided.

Eventual consistency is provided by AWS S3 when there are PUT and DELETES in all regions.

Storage Classes

Storage classes are used to distinguish between the use cases of a particular object stored in a bucket. There are various types of storage classes and they are listed below.

Storage ClassDescription
StandardFrequently used objects
Standard-IAInfrequently used objects
Intelligent-tieringDesigned to optimize storage costs by choosing Standard and Standard-IA for objects
One Zone-IA Infrequently used objects and non-mission-critical data
Glacier Long-term data archiving with retrieval times ranging from minutes to hours
Deep Archive Archiving and rarely accessing with retrieval times averaging 12 hours
 

Object Lifecycle Management

Configuring your object’s lifecycle could ensure they are stored cost effectively for their entire lifecycle. A lifecycle configuration is a set of rules that define actions that AWS S3 applies to a group of objects. There are two types of actions:

  • Transaction Actions
    • This action defines objects’ transition from one storage class to another.
    • You might have provided your object with a Standard class at first, then after 2 months you want to make it Standard-IA, and after a year you want to keep it in Amazon Glacier.
  • Expiration Actions
    • This action deletes objects in the Amazon S3 bucket.
    • Also, S3 deletes the expired objects on your behalf.
expiration actions

But you might think, why do you need a lifecycle for the objects? Check out these examples.

  • You wanted to store log data for the month of April for services; you might need it for a week or a month, and then you might want to delete it.
  • You have objects which are frequently used for a week and then they become infrequent. After that, once the usage for it has reduced to the rock bottom, you can archive it and then delete it.
  • You also might store data for long-term archiving

Object Versioning

Object versioning provides the flexibility of storing objects with the same name by giving objects version numbers. This prevents unintended overwriting or deletion of the objects.

For example, you have a file called image.jpg with the versioning of 111, and now you are uploading another file named image.jpg, again. So, the newly uploaded image.jpg file will have a versioning of 222. So, they are image.jpg (version 111) and image.jpg (version 222).

Versioning can also be used so that you can compare the older versions of the file.

Encryption

Using S3 default encryption you can set the default encrypted behavior for an Amazon S3 bucket. You can also create a default encryption where every object gets encrypted when stored in a bucket. The objects are encrypted using server-side encryption with either Amazon S3-managed keys (SSE-S3) or AWS KMS-managed keys (SSE-KMS).

Advantages of AWS S3 Service

advantages of S3

  • Scalability on Demand
    • If you want your application’s scalability varying according to the change in traffic, then AWS S3 is a very good option.
    • Scaling up or down is just mouse-clicks away when you use other attractive features of AWS.
  • Content Storage and Distribution
    • S3 in Amazon could be used as the foundation for a Content Delivery Network. Because Amazon S3 is developed for content storage and distribution.
  • Big Data and Analytics on Amazon S3
    • Amazon QuickSight UI can be connected with Amazon S3, and then large amounts of data can be analyzed with it.
  • Backup and Archive
    • Whether you need timely backups of your website, or store static files for once, or store versions of files you are currently working on. S3 in Amazon has got you covered.
  • Disaster Recovery
    • Storing data in multiple availability zones in a region gives the user the flexibility to recover files, which are lost, as soon as possible. Also, the cross-region replication technology can be used to store in any number of Amazon’s worldwide data centers.

Enough with the theory. Now, moving on with this Amazon S3 tutorial, let us see how to create a S3 bucket in Amazon Web Services
