Study Notes

Here is a summary of the text in detailed bullet points:

Introduction to S3 Tutorial*
This tutorial is about Amazon S3, a cloud storage service provided by AWS
The tutorial will cover the features and technical details of S3
What is Cloud Storage?*
Cloud storage is a service that provides web-based storage for data
Data can be accessed, backed up, and shared over the internet
Cloud storage is a pay-as-you-go model, with no upfront costs or commitments
Types of Storage in AWS*
S3 (Simple Storage Service) - an object storage service
EBS (Elastic Block Store) - a block-level storage service that attaches to EC2 instances
EFS (Elastic File System) - a file-level storage service that can be accessed by multiple EC2 instances
Glacier - a long-term archival storage service
Storage Gateway - a service that integrates on-premises storage with AWS cloud storage
Snowball - a data import/export service that uses a physical device to transfer large amounts of data
How Things Were Before S3*
Before S3, storing and managing large amounts of data was challenging and expensive
Companies had to provision and manage their own storage infrastructure, which was time-consuming and costly
What is S3?*
S3 is an object storage service that provides a highly durable and scalable storage solution
S3 is designed for storing and retrieving large amounts of data
S3 provides 11.9 durability and 4.9 availability, meaning that data is highly available and durable
Benefits of Using S3*
Highly durable and scalable
Low cost, with a pay-as-you-go pricing model
Highly available, with data accessible from anywhere in the world
Secure, with features like encryption and access controls
Flexible, with multiple storage classes and lifecycle management options
S3 Storage Classes*
S3 Standard - for frequently accessed data
S3 Infrequent Access (IA) - for less frequently accessed data
S3 One Zone-Infrequent Access (IA) - for less frequently accessed data that is stored in a single Availability Zone
S3 Glacier - for archival storage of infrequently accessed data
S3 Reduced Redundancy Storage (RRS) - for non-critical data that can be reproduced quickly
Lifecycle Management*
Lifecycle management is a feature that allows you to define rules for transitioning data between storage classes
Rules can be based on time, with data automatically transitioning to a different storage class after a certain period of time
Lifecycle management can help reduce storage costs by automatically moving data to a lower-cost storage class
Bucket Policies*
Bucket policies are permission files that can be attached to an S3 bucket to control access to the bucket
Bucket policies can be used to allow or deny access to specific users or groups
Bucket policies can be written in JSON script
Data Protection*
S3 provides data protection features like encryption and versioning
Encryption can be used to protect data in transit and at rest
Versioning can be used to preserve multiple versions of an object, allowing for easy recovery in case of data loss or corruption
Cross-Region Replication*
Cross-region replication is a feature that automatically copies objects from one bucket to another bucket in a different AWS region
Cross-region replication can be used to provide additional data durability and to serve data to customers in different regions with low latency.- Cross-region replication in Amazon S3 requires versioning to be turned on, creating versions and copies of the data in another region.
This allows for complete data recovery in case the original region goes down, and the replicated region can be used as a standalone bucket.
To transfer data between buckets, proper permissions are required, which can be granted through roles.
Creating a replication rule in the source bucket enables data replication to the destination bucket.
Versioning must be enabled in both the source and destination buckets for replication to work.
Transfer Acceleration is a service that enables fast and secure data transfer from a client to an S3 bucket, reducing latency.
Transfer Acceleration uses CloudFront to copy data locally and then transfer it to the S3 bucket, bypassing the internet.
Enabling Transfer Acceleration can be done in the S3 bucket properties, and it helps eliminate latency when transferring large files.
A tool is available to compare the speed of data transfer with and without Transfer Acceleration, providing a report on the improved speed.
The tool tests uploading files through the internet and CloudFront, providing a calculation of the accelerated speed for different regions.
In the example, uploading a file to San Francisco using Transfer Acceleration was 13 times faster than uploading through the internet.
