AWS Storage- S3, Glacier, EFS, EBS, Storage Gateway

In this course, you will learn about various AWS Storage services available on Amazon Cloud. When you are preparing for an AWS Certification, Storage is the first thing you should learn and explore. You will be learning all kinds of Storage options available on AWS cloud with some hands-on demonstration of how you can actually create and instance and make use of various options available. You will be learning right from creating an AWS free tier account, running the AWS CLI and a brief introduction to AWS, so don't worry if you are a beginner. If you are already familiar with AWS, you can skip the first few sections and head directly to the Storage section. On AWS you will find various kind of Storage services, and you will be learning all of them in this course. Below are the Storage options on AWS:

What is Amazon S3 (Simple Storage Service)?

It is a general-purpose object storage that works well for unstructured data sets such as media content. Amazon S3 provides the highest level of data durability and availability on the AWS Cloud. There are three tiers of storage: one each for hot, warm, or cold data. In terms of pricing, the colder the data, the cheaper it is to store, and the costlier it is to access when needed.

What is Amazon Glacier?

It is a long-term storage service for storage of infrequently accessed data, such as end-of-lifecycle, compliance, or regulatory backups. Different methods of data retrieval are available at various speeds and cost. Retrieval can take from a few minutes to several hours.

What is Amazon EBS (Elastic Block Storage)?

It provides durable block-storage option for use with EC2 instances. Use Amazon EBS for data that requires long-term persistence and quick access at guaranteed levels of performance. There are two types of block storage: solid-state-drive (SSD) storage and hard-disk-drive (HDD) storage.

What is Amazon EFS (Elastic File Storage)?

It provides simple, scalable file storage for use with EC2 instances. Amazon EFS supports any number of instances at the same time. Its storage capacity can scale from gigabytes to petabytes of data without needing to provision storage. Amazon EFS is designed for workloads and applications such as big data, media-processing workflows, content management, and web serving.

What is Amazon Storage Gateway?

It is generally used to quickly transfer data to any of the cloud storage- S3, EBS, EFS, or Glacier. You can move on-premise data to the Cloud with simplified storage management.
