Elastic Block Store (EBS), a scalable block storage solution offered by AWS (Amazon Web Services), offers permanent storage for EC2 (Elastic Compute Cloud) instances. An EC2 instance can have an EBS volume attached to it as a virtual hard drive to store data.es:

The following are some significant traits and qualities of EBS volumes:

1. EBS volumes are made to last and offer long-term storage, therefore they are persistent. Even if the connected EC2 instance is stopped or terminated, the data on an EBS volume continues.

2. Elasticity: EBS volumes can be created in a variety of sizes, from 1 GB to 16 TB, and scaled up or down as necessary. This enables you to accommodate your applications’ fluctuating storage needs.

3. Performance: To accommodate a range of workloads, EBS volumes provide numerous performance options. Four different EBS volume kinds are available:

( 1 ) Suitable for a variety of tasks with balanced performance and cost is the general-purpose SSD (gp2/gp3).

( 2 ) SSDs with provisioned IOPS (io1/io2) are made for high-performance databases and applications that demand reliable and quick I/O.

( 3 ) Throughput Optimised HDD (st1): Designed for heavy streaming workloads with frequent access.

( 4 ) Old HDD (sc1): Designed for workloads that access cold data less frequently

4. Snapshots: EBS volumes support creating point-in-time snapshots, which are incremental backups of the volume’s data. Snapshots are stored in Amazon S3 and can be used to restore volumes or create new volumes.

5. Using the AWS Key Management Service (KMS), you can enable encryption at rest for your EBS volumes. This additional layer of protection further protects your data.

6. High Availability: To increase redundancy and availability, EBS volumes can be linked to an EC2 instance either inside the same availability zone (AZ) or across separate AZs.

7. Data management: As needed, EC2 instances can be quickly attached, detached, and reattached to EBS volumes. Additionally, you can copy volumes, take snapshots, and share snapshots among AWS accounts.

Databases, file systems, content repositories, and other sorts of applications frequently use EBS volumes to provide persistent storage on AWS. They provide versatility, toughness, and performance for data storage and access in the AWS cloud.

Following steps 

1. Open the AWS Management Console and log in.

2. Activate the EC2 service.

3. Create an ” EC2 ” instance

4. Connect to the instance ( puTTY )

Create an LVM logical volume on a partition created on an EBS volume

Short description

1. You can allocate disc space as well as stripe, re-mirror, and resize logical volumes with LVM. You can assign a single EBS volume or a group of EBS volumes to one or more physical volumes using LVM.
Follow these procedures to extend the partitions and use LVM on your EBS volume:

2. To create a partition, use the fdisk command. Enter 8e00 as the variable’s Hex or GUID. The partition /dev/xvdf1 is created on /dev/xvdf in the example that follows.

[root@ip-172-31-2-182 ~]# fdisk /dev/xvdf

Welcome to fdisk (util-linux 2.37.4).
Changes will remain in memory only, until you decide to write them.

An essential security precaution is setting up Multi-Factor Authentication (MFA) for your AWS root account. By requiring an additional verification step when logging into your AWS account, MFA adds an extra layer of security. The following describes how to set up MFA for your AWS root account:

Step 1: Use your root account login information to access the AWS Management Console.

Step 2: Select “My Security Credentials” from the dropdown menu by clicking on your account name or number in the top navigation bar. The page titled “Security Credentials” will then be shown.

Step 3: Scroll down to the “Multi-Factor Authentication (MFA)” section on the “Security Credentials” page, and then select the “Manage MFA” option.

Step 4: Select “Continue” from the menu on the “Manage MFA Device” page to begin the configuration procedure.

Step 5: You will be given the option of selecting an MFA device. These are your two choices:

1. Virtual MFA device: This method generates MFA codes using a smartphone app, such as Google Authenticator or Authy.

2. U2F security key: With this method, MFA is provided by means of a physical security key, such as a YubiKey.

Select the “Continue” button after making your selection according to your preferences.

Step 6: To configure your chosen MFA device, adhere to the on-screen instructions:

1.  Install a compatible app on your smartphone, then scan the QR code provided by AWS to use a virtual MFA device. You must input the 6-digit authentication number generated by the app on the AWS page.

2. You must place a U2F security key into a USB port and then push the key’s button when instructed to do so. page.

Step 7: AWS will give you backup codes when you set up your MFA device. In the event that you lose control of your MFA device, these codes are crucial. Keep these codes in a safe place at all times.

First, we need to create an s3 Bucket steps are given below:

 Step 1: Log on to your AWS Console.
Step 2: go to the Search bar  ” S3 services “

Step 3: Click on S3  Scalable Storage in the Cloud” and proceed further

Step 4: Create a new Bucket

In the general configuration category:

Step 5: Enter the bucket name  (delete-object-put object bucket in our case) 

Step 6: Next, choose the  AWS region,  [Asia Pacific (Mumbai) ap-south-1].

ACLs disabled (Recommended)

Bucket owner enforced – Bucket and object ACLs are disabled, and you, as the bucket owner, automatically own and have full control over every object in the bucket. Access control for your bucket and the objects in it is based on policies such as AWS Identity and Access Management (IAM) user policies and S3 bucket policies Objects can be uploaded to your bucket only if they don t specify an ACL or if they use the bucket-owner-full-control canned ACL.

Block Public Access settings for this bucket

Public access is granted to buckets and objects through access control lists (ACLs), bucket policies, access point policies, or all. In order to ensure that public access to this bucket and its objects is blocked, turn on Block all public access. These settings apply only to this bucket and its access points. AWS recommends that you turn on Block all public access, but before applying any of these settings, ensure that your applications will work correctly without public access. If you require some level of public access to this bucket or objects within, you can customize the individual settings below to suit your specific storage use cases

Bucket Versioning

Versioning is a means of keeping multiple variants of an object in the same bucket. You can use versioning to preserve, retrieve, and restore every version of every object stored in your Amazon S3 bucket. With versioning, you can easily recover from both unintended user actions and application failures.

Disable

Step 7: Click on Create Bucket.

If the bucket is created successfully, you will see a message like this on the top of the page:
