2. Overview of AWS S3

  • 2-1. Introduction to Amazon S3

  • Amazon S3 (Simple Storage Service) is a scalable cloud storage service provided by Amazon Web Services (AWS). It allows you to store and manage data with high durability and availability, making it suitable for a variety of use cases including data backup, archival, and big data analytics. Amazon S3 is designed to provide secure and flexible storage options for users.

  • 2-2. Key Features of Amazon S3

  • The key features of Amazon S3 include: - **Scalability**: S3's architecture allows you to scale storage resources up or down based on your needs without any disruption. - **Security**: S3 employs multiple layers of security, including AWS Identity and Access Management (IAM) and bucket policies, to control access to data. For example, you can configure S3 bucket policies using the Policy Generator to grant or deny permissions. - **Durability and Availability**: S3 is designed for 99.999999999% (eleven 9s) of durability and 99.99% availability of objects over a given year. - **Integration**: S3 integrates easily with other AWS services and third-party applications. For instance, the Beefree SDK provides a feature that allows you to connect an Amazon S3 bucket to manage customer assets without the need for a new File System Provider. This is achieved by providing a compliant folder structure and filling out a configuration form in the Beefree SDK Console. - **Flexible Storage Management**: S3 offers various storage classes (Standard, Infrequent Access, Glacier) to manage data costs efficiently based on retrieval requirements. - **Custom S3 Buckets**: Users can create and configure custom S3 buckets for specific needs. These buckets must follow AWS naming conventions and be publicly accessible. Additionally, S3 bucket Access Control List (ACL) settings ensure that write permissions are disabled for unauthorized users. - **Policy Configuration**: Users can configure bucket policies using the “Policy Generator” in the AWS Management Console. This tool helps set policies to control access to bucket resources securely and effectively.

3. Configuring AWS S3 Buckets

  • 3-1. Creating and Setting Up Custom S3 Buckets

  • Custom S3 Buckets are a feature in Beefree SDK that allow users to connect their own Amazon Web Services S3 bucket to their Beefree application. This feature enables the storage and management of customers' assets without the need to build a new File System Provider. By providing a compliant folder structure and filling out a simple form, users can store images in an 'Images' folder and thumbnails in a 'Thumbnails' folder. It is recommended that these folders be placed in the root of a dedicated bucket for performance reasons. The bucket must be publicly accessible, and specific Access Control List (ACL) settings should ensure that 'List objects,' 'Write objects,' and 'Write bucket permissions' are disabled for the Everyone user. Additionally, shared files can be provided to users, showing sample images or application-specific images as read-only assets.

  • 3-2. Configuring Policies Using AWS Management Console

  • To configure a bucket policy using the 'Policy Generator' in the AWS Management Console, follow these steps: 1. In the S3 bucket dashboard, click on the 'Permissions' tab and select the 'Edit' button under the 'Bucket policy' section. 2. In the 'Edit bucket policy' dialog box, click the 'Policy Generator' button. 3. Set the policy type to 's3 Bucket Policy,' effect to 'Allow,' principal to "" (allowing any AWS user or service to access the resources), AWS service to 'Amazon S3,' and action to 'GetObject.' 4. Set the Amazon Resource Name (ARN) to 'arn:aws:s3:::myBucketName/' and add conditions such as requiring secure transport and TLS version 1.2. 5. Review and generate the policy, then add the generated policy to the bucket's policy by clicking 'Add Statement' and 'Save changes.' 6. Test the configured policy by accessing objects within the bucket using both secure and non-secure connections to ensure it works as intended. After successful testing, the policy will allow any AWS user or service to retrieve objects from the specified bucket under the defined conditions.

  • 3-3. Generating Thumbnails and Transferring Files

  • For thumbnail generation, image files in the File Manager are resized to 200x200 pixels. Tools like ImageMagick can be used to convert and resize images: - To convert one file: `convert image1.jpg -resize 200x200 image1.jpg_thumb.png` - To resize many files: `mogrify -resize 200x200 myimages/*jpg` - To convert many files to PNG format: `mogrify -format png myimages/*jpg` For example, uploading 'image1.jpg' in the root directory creates a key 's3://my-custom-bucket/path/to/images/my-uid/image1.jpg.' The corresponding thumbnail is named 'image1.jpg_thumb.png' and is stored at 's3://my-custom-bucket/path/to/thumbnails/my-uid/image1.jpg_thumb.png.' Similarly, uploading 'image2.jpg' in a nested directory creates keys for the image and its thumbnail in respective paths. To move from the default S3 bucket to a custom bucket, users need to submit a support ticket through the Beefree SDK Console if they have files that need to be transferred.

4. Connecting Amazon S3 to Other Services

  • 4-1. Connecting Datalore to Amazon S3

  • According to the reference document titled 'Connect to an Amazon S3 cloud storage | Datalore,' creating a connection to an Amazon S3 cloud storage involves Datalore's New cloud storage connection dialog. This interface is fundamental for establishing a data source. The process entails attaching an Amazon S3 bucket to the service, making use of Datalore's configuration options to integrate the bucket properly. The key difference between various scenarios lies in accessing the connection dialog, but the basic procedure remains consistent.

  • 4-2. Optional Parameters in Amazon S3 Connection

  • The reference document also provides insights into configuring optional parameters for Amazon S3 data sources. When creating an Amazon S3 data source, users can utilize a field dedicated to optional parameters. The document specifies two examples illustrating the application of these optional parameters, which might be instrumental in tailoring the connection setup to specific requirements. The use of optional parameters can optimize the integration process, ensuring that the connection settings align perfectly with user needs.
