What is S3 in AWS?

In this article, we are going to learn S3 is also called the Simple Storage Service and what is the use of s3 in AWS we will see step by step.

AWS is a collection of cloud computing services that are owned and operated by Amazon.com. 

It provides a variety of on-demand computing resources over the internet, such as operating systems, development environments, database tools, storage buckets, and server time.

What is S3?

One of these services in AWS is called S3 which stands for “Simple Storage Service“, It’s basically a web service that provides storage containers/buckets which can be accessed via the HTTP protocol.

It is simply a service that stores and manages files in the amazon web services system, Although you can host files to end-users, that’s not all it’s used for.

S3 is sort of a catch‑all service used by other services in AWS, like CloudWatch and Elastic Beanstalk, for instance.

S3 can be used for any type of file, and the only limitation is a maximum size of 5 TB, and that was not a mistake, The maximum object size is actually 5 TB.

According to AWS documentation, I haven’t actually tried this, the largest file size that you can upload in a single put operation is 5 GB, but there are other methods to upload a larger object in separate operations.

Why do we need S3 in AWS?

AWS is a cloud computing platform from Amazon. It offers a wide variety of services, including storage and hosting, in various levels of privacy and security.

S3 or Simple Storage Service is often used as a medium-term object store that only stores the data for a specified period of time.

It has some features that make it attractive to AWS customers:-

1. Simple to set up and maintain

2. Encryption at rest

3. Backups of S3 objects

4. Reduced latency access

What is a Structure in S3?

Buckets are the foundational structure in S3 and A bucket is your root resource to which you can add, delete, or modify objects.

Similarly, different configuration options that you can add on buckets include logging, hosting options and grating permissions, etc.

Buckets can be configured to trigger events when changes happen, preserve old versions of any objects, and automatically replicate objects to different regions.

Once created, buckets are assigned URLs to which you can access the objects contained within them. When the permissions for objects are modified to allow anonymous access, S3 can be used to host static files for websites.

AWS users are able to have access to many storage options using S3 buckets.

They are two types of buckets that are available to users:

1. Standard type

2. Reduced redundancy type.

How is S3 use for Hosting?

In AWS if you are working on your own web application or you want to host your website then S3 makes it simple to use for hosting a static website.

Insight the bucket configuration options you can easily do enable the static website hosting for the given bucket or modify the configuration options.

You still have object‑level permissions to give access to anonymous or authenticated users, but the bucket itself will respond to requests and be enabled to interact with Route53 URLs.

To host and Setup your website on S3 you need very little time and effort because S3 in AWS is a quick and easy way to get a static website up with a very minimal cost.

How to solve the latency problem?

If hosting a site like this or even just assets for website‑like images sounds like your use case, you may be wondering how to solve the latency problem I mentioned in the last module.

Similarly, With S3 in AWS, you can automatically replicate files to other regions, but AWS provides a better solution.

In S3 using another service from Amazon called CloudFront, you can cache your content, sometimes called edging your content, at locations around the world.

What is the Cost of S3 in AWS?

S3 is price‑based on three aspects, the amount of data stored, the number of requests for objects made, and the amount of data transferred.

Prices are different per region, and base costs get cheaper as volumes go up. But here are the prices for the first tier of each in the Oregon region.

Also note, these prices are per bucket. AWS charges 2.3 cents per gigabyte of data stored. Pretty reasonable.

Requests are priced differently based on the type of request but put requests are basically half a cent per 1,000 requests. And for data transferred, the first gigabyte per month is free and then 9 cents per gigabyte up to 10 TB.

Overall, I think S3 is pretty reasonably priced for storage and has a low barrier of entry, not to mention that there is a free tier giving you 5 GB of storage and some free requests and data transfer for the first year.

What are the benefits of s3?

AWS S3 is a cloud service that provides developers and businesses with storage space to host data that’s accessed over the Internet.

It’s designed primarily for enterprises and other organizations to host their data, ensuring security and compliance with local legislation.

Whilst developers can store videos, music, images, and web pages through the use of the service for any purpose, AWS does not recommend using it as a long-term backup solution.

It is a highly scalable, flexible, durable storage web service that provides access to data on user-defined amounts of storage.

The main benefits of S3 are the ability to use the API to store or retrieve data, automatic scaling up or down as needed, and 99.99% durability for objects stored in S3.


AWS enables a large level of data storage, processing, and management operations to make today’s business transaction very smooth and scalable.

Amazon S3 is a very well-known and highly consuming storage system in today’s market for the best cloud-based support for optimized data handling.

There are other AWS services also you can use and explore for your understanding and development purpose based on your business and client needs.
