What is storage called in AWS?
AWS storage services are grouped into three different categories: block storage, file storage, and object storage. File Storage.
Types of Storage:
Five types of storage services are available.
a) Simple Storage Service(S3)
b) Elastic File System
c) EBS (Elastic Block Storage)
d) Glacier
e) Snowball
Simple Storage Service(S3):
It is object-level storage. You can store any object or file and can access it from anywhere (option to make it public or private).
It is used to store unstructured data.
EFS(Elastic File System):
- EFS is a kind of common storage system. You can share this storage between multiple regions or availability zones. You can store software update files, and patch files in this storage. You can use this storage for Linux-based systems.
EBS(Elastic Block Storage):
It is connected with EC2-Instance, you can access this storage by EC2 only.
It is a Block-Level Storage.
Glacier:
Now Glacier does not exist separately It become part of S3. It is very cheap but highly reliable.
If you want to store data for a long time like 50 years at the cheapest price then you can use Glacier.
Snowball:
- Snowball is a portable device. Suppose an organization has data in large amounts and requires to migrate that data to AWS Cloud then it is too tough to migrate it to a cloud server. In that case, they send a portable device to that organization and the organization will upload the data in that send to the data center. They will upload that data to a cloud server.
❄Tasks:
Task-01
Launch an EC2 instance using the AWS Management Console and connect to it using Secure Shell (SSH). Create an S3 bucket and upload a file to it using the AWS Management Console. Access the file from the EC2 instance using the AWS Command Line Interface (AWS CLI).
Step 1: Log in to AWS by using the root user.
Step 2: Launch an EC2-Instance on AWS.
Step 3: Copy the SSH Command to access the EC2-Instance.
Step 4: Go over the search button on the AWS dashboard and type S3.
Step 5: Click on the "Create Bucket" option for creating storage.
Step 5: Give a Bucket Name to create a bucket. Select Region, according to that which you use to create your EC2-Instance ( It should be the same), and click on the "Create Bucket" button.
Step 6: Verify your bucket created successfully.
Congratulations!! your bucket was created successfully.
Step 7: Upload the document over the bucket, Click over the upload button.
Now Check if it's uploaded successfully or not.
Step 8: Performing the task using CLI, require to install AWS CLI on EC2-Instance.
Verify whether it's installed successfully or not.
Configure AWS CLI in your EC2-Instance.
aws configure
aws sts get-caller-identity
Step 9: After installing successfully, Access Storage by using AWS CLI and copy in locally (EC2-Instance).
# list of storages
aws s3 ls
# Copy file from storage to Local Machine
aws s3 cp <bucket_url> <path_to_loacl_machine>
finally S3 storage and uploaded files accessible from AWS CLI.
Task-02
Create a snapshot of the EC2 instance and use it to launch a new EC2 instance. Download a file from the S3 bucket using the AWS CLI. Verify that the contents of the file are the same on both EC2 instances.
Step 1: For Creating Snapshot, Go over the Volume section and select volume then click on "Create Snapshot".
Step 2: Give a name to your snapshot and then click on "Create Snapshot".
Step 3: Finally Snapshot created successfully.
Step 4: Create a new EC2-Instance by using the above snapshot.
To select snapshot, click on Browse more AMIs then select snapshot.
Step 5: Verify EC2- Instance Created Successfully.
Step 6: Access EC2-Instance by using the SSH key for performing tasks on CLI.
Step 7: Access Storage and check uploaded file exists or not.
# list of storages
aws s3 ls
# Copy file from storage to Local Machine
aws s3 cp <bucket_url> <path_to_loacl_machine>
