What Are AWS S3 Bucket Limits or Restrictions

Amazon Simple Storage Service (S3) is a cloud storage solution that provides data availability and security. It allows users to store and retrieve any amount of data from anywhere on the network. The process of creating buckets on Amazon S3 is simple, but it is important to note that S3 also has limits and quotas. Understanding the limits of AWS S3 buckets is essential to creating buckets smoothly. In this article, we will discuss some of the major limits of AWS S3 buckets.

AWS S3 Bucket Limit from 3 Aspects

The next section will talk about AWS S3 bucket quota limits in four parts Bucket Limits, Bucket Size Limits, Object Limits, and Performance Limits, after complying with the following limitations you can operate and create anS3 bucket smoothly.

Bucket Limits

✔ Number of Buckets

Typically, you can create 100 buckets per AWS account, but if you need more, you can request an increase in the limit from the AWS Support Center.

✔ Bucket Name Requirements

It is important to ensure that each S3 bucket name is unique and that the naming convention adheres to DNS-compliant naming conditions, as listed below are some of the naming conventions you need to follow.

• The bucket name must be between 3 and 63 characters in length.
• The bucket name can contain only lowercase letters, numbers, hyphens, and periods, and cannot begin or end with a hyphen or period.
• The bucket name cannot be formatted as an IP address, for example, 192.168.1.1.
• The bucket name cannot contain two adjacent periods.

Object Limits

✐ AWS S3 Bucket Size Limit

There is no fixed limit to the total size of data that an S3 bucket can hold, but individual objects stored in S3 can be up to 5 TB in size, so you can store a large amount of data in a bucket as long as you keep each object within the maximum limit.

✐ Total Number of Objects

Although there is no limit to the number of objects that can be stored in an S3 bucket, the performance of an S3 bucket may suffer if there are too many.

Performance Limits

✦ Request Rate Limit

S3 can handle large numbers of files and has high availability, but to optimize performance when designing your application, keep hotspots to a minimum. Hot spots occur when there are many requests for a single object or a few objects.

✦ Throughput Limits

You need to be aware of your throughput limitations; the maximum throughput for GET requests is typically about 3,500 requests per second per prefix. For PUT requests, the maximum throughput is about 1,100 requests per second per prefix. Using a good key naming scheme can help you stay in the correct.
