What is S3 Object Storage?

S3 (Simple Storage Service) Object Storage is a simple, scalable, and secure method for storing massive amounts of data in the cloud. Unlike traditional file systems with complex hierarchies, S3 uses a flat structure with unlimited "buckets." Within these buckets, each file is stored with a unique identifier for easy retrieval.

First introduced by Amazon Web Services (AWS) in 2006, the S3 protocol has become the de facto global standard for cloud object storage. Data is accessible from anywhere via HTTP/HTTPS, a web interface, or a powerful API, ensuring instant availability and easy integration.

Every object stored in S3 consists of three core components:

  • A unique identifier – The key that allows you to directly access any file.
  • Metadata – Descriptive information about the object, such as its name, size, type, and creation date.
  • Content – The actual content of the file—your documents, images, videos, backups, etc.

You control access permissions and can set automated lifecycle rules (e.g., archive old files).

S3 Object Storage is ideal for a range of applications, including data backups, large-scale data lakes, multimedia libraries (audio, video, images), and long-term archival.

Benefits of S3 Object Storage

  • No extra load on your system. Storage runs independently, saving resources.
  • Free inbound traffic. Upload as much data as you need — no extra fees.
  • Seamless integration. Works with your existing business tools.
  • Unlimited scalability. Store any amount of data. The storage automatically scales as your data grows. 
  • 24/7 availability. We ensure uninterrupted service availability so that you can access your data at any time.

FAQ

Is there a limit to the amount of data I can store?
No. You can store an unlimited amount of data.
What can I do with the data I store?
You can upload data to the repository, make copies, move it around, download it, and delete it. Data can be organized into folders.
How is Object Storage different from Google Drive, Dropbox and others?
Google Drive, Dropbox and other similar storage solutions are great if you need to store small amounts of non-sensitive data. S3 Object Storage, on the other hand, can store the data of large organizations and offers access control and a high level of information protection. It is also easily scalable to meet your business needs.
Is my data protected?
All data is stored in secure data centers equipped with surveillance cameras, access control systems, security, etc.
Can I connect an Object Storage container as a network drive?
Yes, you can connect the container as a network drive using the FTP protocol or any other method.
Does Object Storage work with all applications?
No. The application must support the S3 REST API.
How is data backed up in Object Storage?
Copies of the data are hosted on geo-remote servers. If one of the servers fails, the data is not lost, but remains available through redundancy.
Why is 'no hierarchy' an advantage of object storage?
Building a hierarchy significantly increases the path to the data (object) and therefore the response time of the application. In object storage, data lies flat and can be transmitted almost immediately to the application or to the Internet via http/https.
How do I migrate from AWS S3, Azure and other storage to Cloud4U Cloud Object Storage?
You can migrate data using Rclone or similar software.
What is metadata?
Metadata is information about objects. This includes the name, file type, file size and creation date. Metadata is necessary for storage management. It makes it easier to search, sort and set access policies.
What kind of information can metadata include?
Anything! You can add any kind of information, from the various properties of an object to the rights associated with the object for each specific user.
