How to create the EBS Volume via aws console or aws cli

Amazon Elastic Block Store (EBS) is a block-level storage service offered by Amazon Web Services (AWS). In this article, we will explore how AWS EBS volumes work, their use cases, pricing model, and address frequently asked questions to understand the benefits and capabilities of this versatile storage solution.

  1. How AWS EBS Volume Works: AWS EBS provides persistent block-level storage volumes that can be attached to Amazon EC2 instances. Key features and workings of EBS volumes include: a. Block Storage: EBS volumes offer raw block storage that can be formatted with a file system to store and retrieve data at the block level. b. Availability and Durability: EBS volumes are replicated within an Availability Zone (AZ) to ensure high availability and durability. They provide synchronous replication, protecting against the loss of data due to hardware failure. c. Elasticity and Performance: EBS volumes can be easily resized to meet changing storage requirements. You can choose from different volume types optimized for different workloads, providing varying performance characteristics such as provisioned IOPS, throughput, and burst performance. d. Snapshots and Backup: EBS volumes can be snapshotted, creating point-in-time backups that can be used to restore data or create new volumes. Snapshots are stored in Amazon S3, offering long-term data durability and ease of data migration.
  2. Use Cases of AWS EBS Volume: a. Database Storage: EBS volumes are commonly used to store database files, providing persistent and high-performance storage for database servers like Amazon RDS, Amazon Aurora, and self-managed database solutions. b. Application Storage: EBS volumes serve as reliable storage for application files, binaries, and other data required by applications running on EC2 instances. They are ideal for storing data that requires frequent access and persistence. c. File Storage: EBS volumes can be used as block storage for file servers, enabling shared file systems across multiple EC2 instances or serving as a central repository for files accessed by applications or users. d. Data Analytics: EBS volumes are suitable for storing and accessing large datasets required for data analytics platforms like Amazon Redshift, Amazon EMR, or custom analytics solutions running on EC2 instances. e. Backup and Disaster Recovery: EBS snapshots provide a convenient and cost-effective method for backup and disaster recovery. Snapshots can be used to create new volumes or restore data in case of data loss or system failures.
  3. Pricing Model: AWS EBS volumes have separate pricing components: a. Volume Size: You are billed based on the size of the provisioned storage in GB per month. b. Volume Type: Different volume types have varying pricing structures, such as General Purpose SSD (gp2), Provisioned IOPS SSD (io1), Throughput Optimized HDD (st1), and Cold HDD (sc1). c. Data Transfer: Data transferred out of an EBS volume to another AWS service or to the internet incurs data transfer costs.

It is recommended to review the AWS website or consult the official AWS documentation for the most up-to-date and detailed information regarding EBS pricing, as it may vary based on regions and specific usage patterns.

  1. Frequently Asked Questions (FAQ): a. Q: Can I attach an EBS volume to multiple EC2 instances simultaneously? A: No, an EBS volume can only be attached to a single EC2 instance at a time.b. Q: How do I resize an EBS volume? A: You can resize an EBS volume using either the AWS Management Console, AWS CLI, or AWS SDKs. Resizing can be done while the volume is in use, but it requires the file system to be extended to utilize the additional space.c. Q: Can I share EBS volumes between AWS accounts? A: Yes, you can share EBS snapshots with other AWS accounts, allowing them to create volumes from the shared snapshot. However, the direct sharing of EBS volumes between accounts is not supported.d. Q: How frequently can I take EBS snapshots? A: You can take EBS snapshots as frequently as needed. It is a best practice to schedule regular snapshots based on your desired recovery point objective (RPO) and retention policy.

How to create the ebs volume in aws console and cli commands

To create an EBS volume, you can use either the AWS Management Console or the AWS CLI (Command Line Interface). Here’s a step-by-step guide for creating an EBS volume using both methods:

Creating an EBS Volume in the AWS Management Console:

  1. Log in to the AWS Management Console.
  2. Navigate to the EC2 service.
  3. Click on “Volumes” in the left-hand navigation pane.
  4. Click on the “Create Volume” button.
  5. Specify the volume settings, including:
    • Availability Zone: Select the desired Availability Zone where the volume will be created.
    • Volume Type: Choose the appropriate volume type based on your requirements (e.g., General Purpose SSD, Provisioned IOPS SSD, Throughput Optimized HDD).
    • Size: Enter the desired size for the volume in gigabytes (GB).
    • Additional settings: Adjust any additional settings such as encryption, snapshot source, or tags, if needed.
  6. Click on the “Create Volume” button to create the EBS volume.

Creating an EBS Volume using AWS CLI Commands:

  1. Install and configure the AWS CLI on your local machine if you haven’t already.
  2. Open a terminal or command prompt.
  3. Run the following command to create an EBS volume:
  4. aws ec2 create-volume --availability-zone us-east-1a --size 50 --volume-type gp2 Replace “us-east-1a” with the desired Availability Zone and adjust the size and volume type parameters as needed.
  5. If successful, you will receive a JSON response with details about the newly created EBS volume, including the volume ID.

Note: Ensure that you have the necessary permissions and have configured the AWS CLI with appropriate access keys or roles to create an EBS volume using CLI commands.

Remember to attach the created EBS volume to an EC2 instance using either the AWS Management Console or the AWS CLI. The EBS volume needs to be mounted and formatted with a file system before it can be used to store data.

Whether you use the AWS Management Console or the AWS CLI, ensure that you follow AWS best practices for managing and securing your EBS volumes, such as regular backups using snapshots and appropriate access control policies.

Please note that the exact steps may vary slightly based on updates to the AWS Management Console or changes to the AWS CLI commands

Conclusion: AWS EBS volumes provide scalable and reliable block-level storage for various use cases, including database storage, application data, file storage, and backup. With its flexibility, elasticity, and integration with other AWS services, EBS enables businesses to efficiently manage their storage requirements and achieve high-performance data persistence. Understanding how EBS volumes work, their use cases, pricing model, and frequently asked questions helps in making informed decisions while leveraging this powerful storage solution on the AWS cloud.
