[NEW] Amazon S3 Deep Dive: The Ultimate Guide to AWS Storage

Use the S3 standard tier, the general purpose storage for frequently accessed data. Deliver high throughput, low latency, 99.99% availability, with writes across three availability zones as default storage class.

Automatically balance cost and access with S3 intelligent-tiering, which moves data among frequent access, infrequent access, archive access, and deep freeze tiers based on usage, with no retrieval charges.

Explore how Amazon S3 standard infrequent access offers lower storage costs with retrieval fees, ideal for backups and disaster recovery, while maintaining durability across three availability zones.

Trace Glacier’s evolution from a separate service to a core part of Amazon S3, with instant, flexible, and deep freeze retrieval options through lifecycle rules and S3 API.

Glacier instant retrieval provides millisecond access to archival data at low cost, with a 90-day minimum storage duration and a per-gig retrieval fee, while lifecycle rules move data through tiers.

Explore Amazon S3 Glacier flexible retrieval, a long-term archive option with expedited, standard, and bulk retrievals, priced by latency and a 90-day minimum charge.

Explore Amazon S3 Glacier Deep Archive, the lowest-cost storage class for long-term retention, with standard retrieval in 12 hours or bulk retrieval in 48 hours.

Learn how to manage Amazon S3 storage classes by changing existing objects' storage class and selecting a class during upload, including one zone IA and intelligent-tiering with lifecycle rules.

Move the course cover.jpg to S3 standard IA storage class to reduce costs, and upload three new files to the blog prefix using intelligent-tiering.

Explore how Amazon S3 pricing varies by data volume, storage class, and region, including standard, infrequent access, one zone infrequent access, glacier, glacier deep archive, and intelligent-tiering with volume discounts.

Use the AWS pricing calculator to configure S3 storage estimates, comparing S3 Standard and S3 Glacier Deep Archive for a data analytics workload, including monthly and yearly costs.

Explore how Amazon S3 data transfer costs work, including free 100 GB per month to the internet, tiered pricing, cheaper AWS transfers, and regional price variations.

Explains creating a new S3 bucket in the console with unique-name rules across accounts and region selection, then demonstrates a CLI approach using AWS S3 API.

Explore how S3 applies bucket defaults, including block public access and default encryption with SSE-S3 (or SSE-KMS), to prevent public exposure and auto-encrypt new objects.

Explore bucket defaults in Amazon S3 Deepdive: enable S3 SSL encryption by default, and switch to KMS with a key ARN. Block public access under permissions to protect data safely.

Explore bucket properties and settings such as versioning, tags, encryption, logging, and event notifications. Understand emptying versus deleting buckets, static website hosting, transfer acceleration, object lock, and impact on automation.

Learn how to upload objects to an Amazon S3 bucket using the UI, drag-and-drop, and the AWS S3 sync CLI, with real-time progress and status.

Learn how multi-part uploads handle large files up to five terabytes with parallel, out-of-order parts. Improve throughput and resilience with pause-resume, quick network recovery, and reassembly into an S3 object.

Retrieve and download S3 objects using the console or AWS CLI, view the S3 URI, ARN, and object URL, and filter to PNG images only.

Create and enable a bucket-wide lifecycle rule that moves objects between storage classes. Move objects from standard to Standard-ia after 30 days, then to Glacier instant retrieval after 180 days.

Tag your S3 objects with ten key–value pairs to organize data by projects, teams, or data types, enable access control, support cost allocation, and drive lifecycle and batch updates.

Learn how to tag buckets and individual objects in S3, apply environments and cost center tags, and use tag-based IAM policies to restrict object access to development environments.

Explore Amazon S3 requester pays, which shifts data transfer costs to the requester while the bucket owner covers storage. Enable it for partner data sharing with authenticated access.

Enable requester pays for S3 bucket by editing bucket properties and saving changes, then share bucket with accounts so they cover transfer and request costs while you pay storage costs.

Download a world map jpeg from an s3 bucket using the aws console or cli, delete an older csv, and tag the bucket with cost center 0884 for marketing.

Explore securing access to data in Amazon S3 by configuring IAM policies, bucket policies, and ACL controls, with encryption, ownership rules, and monitoring under the shared responsibility model.

Amazon S3 block public access enforces no public access at account, bucket, or access point levels, overriding ACLs and bucket policies to prevent data exposure.

Demonstrates how IAM policies grant list permissions and how bucket policies grant get and put access, illustrating the interplay between IAM and bucket policies for S3 access.

Learn about access control lists (ACLs) in Amazon S3, a legacy feature discouraged by default use of object ownership and bucket policies.

Discover how to create and attach an IAM policy for a user to manage S3 bucket and object permissions, including KMS key encryption and decryption.

Learn how S3 object ownership assigns control to the owning account and configure it on new or existing buckets with bucket owner enforced, bucket owner preferred, and object writer options.

Learn how Amazon S3 pre signed URLs provide temporary access to bucket objects without public exposure, enabling get or put operations for subscribers, partners, and apps.

Explore how to create and use Amazon S3 pre signed URLs to grant time-limited access to private objects without altering bucket public access settings.

Protect your data in Amazon S3 by implementing backup and recovery, encryption in transit and at rest, and using object versioning, bucket replication, MFA delete, and object lock.

Explore encryption options for data before, during, and after it enters Amazon S3, including client-side encryption on premises with an HSM, in-transit TLS, and server-side encryption at rest.

explain how to encrypt data at rest in S3 with server side encryption and envelope encryption, and manage keys via AWS or your own (sse-s3, sse-c, sse-kms).

Encrypt each uploaded object with a unique data key, encrypted with a master key via envelope encryption. S3 rotates the master key and uses SSE-S3 by default, not encrypting metadata.

Encrypt data at rest in S3 with SSE-KMS keys from AWS KMS; use a customer managed CMK instead of the default to control policies, rotation, aliases, and TLS in transit.

Explore how to configure SSE-KMS in Amazon S3, set default encryption, override bucket settings with a KMS key, and apply customer-managed keys to objects.

Explore how customer-provided keys enable SSE-C encryption at rest in Amazon S3, how keys are not stored, and compare SSE-S3, SSE-KMS, and SSE-C for control and sharing.

Enforce in-transit encryption for S3 by blocking http requests via a bucket policy that requires tls, denying insecure transport and ensuring secure access to bucket objects.

Enable bucket versioning to create distinct object versions, safeguard against accidental deletion, and recover prior data with lifecycle rules.

Replicate S3 objects across buckets, accounts, and regions with versioning, encryption, storage class changes, delete markers, rules, RTC, and S3 batch operations for existing data.

Master S3 replication limits: data created by one rule is not replicated by another. Only new data replicates, and Glacier or deep archive objects are not replicated.

Configure cross region replication by setting replication rules to copy data between buckets in different regions, supporting compliance, reducing latency, and improving resiliency.

Explore same region replication to automatically copy logs and objects across accounts or buckets in the same region, enabling security backups, disaster recovery, log consolidation, and data sovereignty compliance.

Explore how S3 object lock enforces write once, read many data retention with governance and compliance modes, including retention dates, legal holds, and cross-region replication.

Enable origin access control on CloudFront to restrict S3 access to the distribution, blocking direct access and updating the bucket policy to allow only that distribution via Sigv4 signing.

Create a CloudFront distribution for the S3 deep-dive bucket, configure origin and OAC access, update the bucket policy, enable https redirects, and test caching with the CloudFront URL.
