Get a Complete Overview on What is AWS EBS from HKR Trainings

AWS EBS stands for Amazon Web Services Elastic Block Store. It is a scalable block storage service that is designed to be used with Amazon Elastic Compute Cloud (EC2) instances. EBS allows you to create and attach persistent block storage volumes to EC2 instances, which can be used for data storage or as a root partition for the EC2 instances. With EBS, you can create storage volumes that range from 1 GB to 16 TB in size, and you can attach multiple volumes to a single EC2 instance. You can also choose between different types of EBS volumes, such as solid-state drives (SSDs) or hard disk drives (HDDs), depending on your performance and cost requirements. EBS volumes are designed to be highly available and durable, and they automatically replicate data within an Availability Zone (AZ) to protect against failures. You can also create snapshots of EBS volumes, which are point-in-time copies of the data, and use them to create new volumes or restore existing ones. Overall, EBS provides a scalable and reliable storage solution for EC2 instances in the AWS cloud.

What is AWS S3 | A Step by Step Guide on AWS S3

INTRODUCTION: Object storage is offered by Amazon S3 (Simple Storage Service), which was created for the purpose of storing and retrieving any quantity of data or information from anywhere online. Through a web services interface, it offers this storage. It delivers 99.999999999 percent durability and 99.99 percent availability of items while being built for developers to make web-scale computing easier. Additionally, it can hold data files up to 5 terabytes in size.

AMAZON S3 STORAGE CLASSES: Let's examine the various storage classes using a school as an example: 1. For a use case where the latency should be below, Amazon S3 Standard is suitable. Example: Information on student attendance will be often requested and needs to be retrieved fast. 2. For rare data access, use Amazon S3 Standard: can be used in cases where the data is persistent and rarely accessed. Example: While student academic records may not be required on a daily basis, they should be easily accessible if necessary. 3. Where data needs to be archived but high performance is not necessary, Amazon Glacier can be employed. For instance, even if an ex-previous student's record—such as the admission fee—is required on a daily basis, low latency is not necessary. 4. When data is kept in a single region and only sometimes accessed, the One Zone-IA Storage Class can be utilised. Example: The student's report card is kept in a single availability region and isn't used every day (i.e., school). 5. Storage with Amazon S3 Standard Reduced Redundancy is appropriate for use cases where the data is not crucial and can be readily replicated. For instance, library books aren't crucial information and can be replaced if they become lost.

WORKING OF AMAZON S3: Given that Amazon S3 is an object storage service, which it is, data is stored as objects. Buckets are used to store the items. Each item can be thought of as a file, and this bucket is the container that holds all of the files or objects. Making a bucket, giving it a name, and selecting an AWS Region is the first step in storing data in Amazon Simple Storage Service. The data is then posted to this bucket as objects after this is completed. Therefore, each item that is saved has a special key name that aids in identifying it specifically within each bucket. Additionally, S3 and S3 Versioning provide a capability that allows you to store several versions of a file or object in the same bucket. In the event that an object is accidentally erased, this enables its restoration. Similar functionalities exist in Amazon S3 to facilitate effective and efficient work. Buckets and the items within of them can only be accessed when you have authorization to do so, it should be noted. Several factors, such as AWS IAM (Identity and Access Management) settings or ACLs, ensure the objects are secure (Access Control Lists).
