AWS S3

Amazon Simple Storage Service (Amazon S3) is storage for the internet. You can use Amazon S3 to store and retrieve any amount of data at any time, from anywhere on the web. You can accomplish these tasks using the AWS Management Console, which is a simple and intuitive web interface.

AWS S3 connector script reads the logs from the S3 bucket according to the configuration and Each AWS S3 service provides operational metrics or log files to provide insight into how the service is operating. Additionally, many AWS S3 services generate security log data, including audit logs for access, configuration changes, and billing events.

Buckets are the containers for objects. You can have one or more buckets. For each bucket, you can control access to it (who can create, delete, and list objects in the bucket), view access logs for it and its objects, and choose the geographical region where Amazon S3 will store the bucket and its contents.

Pre-requisites

• Connectivity with AWS S3 bucket using valid credentials
  • Required credentials:
    • AWS_SECRET_ACCESS_KEY
    • AWS_ACCESS_KEY_ID
    • AWS account id

Create an AWS S3 bucket

To create a bucket

• Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/

• Choose Create bucket, the Create bucket page is displayed.

• In Bucket name, enter a DNS-compliant name for your bucket. The bucket name must:

  • Be unique across all of Amazon S3.
  • Be between 3 and 63 characters long.
  • Not contain uppercase characters.
  • Start with a lowercase letter or number.

• After you create the bucket, you can't change its name. For information about naming buckets, see Bucket naming rules.

In Region, choose the AWS Region where you want the bucket to reside.

Choose a Region that is close to you geographically to minimize latency and costs and to address regulatory requirements. Objects stored in a Region never leave that Region unless you explicitly transfer them to another Region. For a list of Amazon S3 AWS Regions, see AWS Service Endpoints in the Amazon Web Services General Reference.

In Bucket settings for Block Public Access, keep the values set to the defaults.

By default, Amazon S3 blocks all public access to your buckets. It is recommend to keep all Block Public Access settings enabled. For more information about blocking public access, see Blocking public access to your Amazon S3 storage.

• Choose Create bucket, you've created a bucket in Amazon S3.

You can create one or more IAM users in your AWS account. You might create an IAM user when someone joins your team, or when you create a new application that needs to make API calls to AWS.
