1. Creating an Amazon S3 Bucket

Amazon S3 (Simple Storage Service) allows you to create buckets to store objects (files). When creating a bucket, you must:

• Choose a Region: The bucket region is important for latency and compliance. In this example, the region selected is Europe, Stockholm (eu-north-1).
• Bucket Name: Bucket names must be globally unique across all AWS accounts. If a name is already taken, an error will occur.
  • Example: stephane-demo-s3-v5
• Bucket Type: Some regions may offer "General Purpose" and "Directory" buckets.
  • If "General Purpose" is available, choose it.
  • If you don't see this option, it is automatically set.

2. Configuring Bucket Settings

When setting up the bucket, the following settings are configured:

a. Object Ownership

• ACLs Disabled (Recommended): This enforces security by keeping access within the AWS account.

b. Public Access Block

• Block Public Access (Enabled by Default): Ensures that objects are private and not publicly accessible.

c. Versioning

• Disabled Initially: Versioning allows keeping multiple versions of an object. It can be enabled later.

d. Encryption

• Server-Side Encryption with Amazon S3 Managed Key (SSE-S3): Ensures data security by encrypting objects before storing them.

e. Bucket Key

• Enabled: This helps reduce encryption costs by using a single key for multiple objects.

Once these configurations are set, the bucket is created and appears in the S3 console.
