S3 storage classes

AWS S3 provides us with an array of storage classes suitable for different use cases. For the exam, it’s crucial that you understand the differences between these classes and make the right choice for each use case.

We can configure S3 storage classes at the object level, and a single bucket can contain objects stored across multiple S3 storage classes. Let’s review each storage type in detail.

Based on how we access S3 objects, S3 storage classes can be divided into four categories.

  • Standard
  • Infrequent access
  • Unknown or changing access
  • Archive
