AWS Mastery: S3 Deep Dive

Explore Amazon S3 buckets, objects, and keys for scalable storage. Learn about multi-part uploads, tagging, versioning, and data lakes for backup, archiving, and disaster recovery.

Create an amazon s3 bucket in the correct EU region with a unique name, block public access, enable server-side encryption with s3 managed keys, and use pre-signed urls for access.

Explore IAM policies and bucket policies that control S3 access, enable cross-account and public access, and enforce encryption and block public access settings for secure storage.

Configure S3 bucket permissions to enable public access, adjust public access settings, and generate a bucket policy with the policy generator to allow get object actions.

Learn how to host a static website with Amazon S3, creating an S3 bucket for HTML and images, and configuring public access with a bucket policy to avoid 403 errors.

Configure an Amazon S3 bucket for static website hosting, upload index.html and an image, enable public access, and verify the bucket website endpoint serves your page.

Explore Amazon S3 versioning and learn how activating bucket-level versioning protects against accidental deletions, preserves file iterations, and enables easy rollback to prior versions.

Enable S3 bucket versioning to maintain multiple file versions, view versions with version IDs, revert to an earlier state, and manage deletions with delete markers and permanent deletes.

Explore Amazon S3 replication, including cross region replication and same region replication, enabled by versioning and IAM permissions, with batch replication for existing objects and delete markers, and no chaining.

Set up cross-region replication in Amazon S3 with versioning, origin and replica buckets, and a replication rule, including delete marker replication and optional existing object replication via batch operations.

Explore Amazon S3 storage classes, including standard, infrequent access, Glacier, and intelligent-tiering. Understand durability of 11 nines and varying availability to guide cost and data management.

Create an AWS S3 bucket, upload an object, and review storage classes like S3 Standard, Intelligent Tiering, Standard IA, and Glacier variants; configure lifecycle rules to move objects between tiers.

Create and automate an S3 lifecycle rule to transition current object versions across storage classes, manage non-current versions, and expire or delete outdated data on a customizable timeline.

S3 requester pays data transfer costs, shifting them from bucket owners to authenticated requesters, while owners retain storage fees, enabling cost sharing when distributing large data sets.

Explore Amazon S3 event notifications, triggering actions when objects are created, deleted, or replicated, with filtering and routing to SNS, SQS, Lambda, or EventBridge.

Demonstrates configuring S3 event notifications to send object creation events to an SQS queue, with optional EventBridge integration and testing via file uploads.

Explore S3 encryption methods: SSE-S3, SSE-KMS, SSE-C, and client-side encryption, plus encryption in transit with HTTPS and bucket policies.

Create a bucket, enable versioning, and apply default server-side encryption with SSE-S3 or SSE-KMS; upload a file to verify encryption and observe new versions when encryption settings are edited.
