Storage Services: S3 and EBS

Storage services are an essential component of AWS and provide scalable and reliable storage options for different use cases. Two widely used storage services in AWS are:

S3 (Simple Storage Service)

S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. It allows you to store and retrieve any amount of data from anywhere on the web. S3 uses buckets to organize and store your files, similar to how a file system uses directories.

To create an S3 bucket using the AWS Management Console, follow these steps:

1. Sign in to the AWS Management Console.
2. Navigate to the S3 Dashboard.
3. Click on 'Create Bucket' to start the bucket creation wizard.
4. Enter a unique bucket name and select the region for the bucket.
5. Configure bucket settings, such as encryption and versioning.
6. Review the bucket details and create the bucket.

Once the bucket is created, you can upload, download, and manage your files using the AWS Management Console or programmatically through the AWS SDKs and APIs.

EBS (Elastic Block Store)

EBS provides persistent block-level storage volumes for use with EC2 instances. It allows you to create storage volumes and attach them to EC2 instances, similar to attaching a physical hard drive to a computer. EBS volumes are highly available and durable, with automatic replication within a specific Availability Zone (AZ).

To create an EBS volume using the AWS Management Console, follow these steps:

1. Sign in to the AWS Management Console.
2. Navigate to the EC2 Dashboard.
3. Click on 'Volumes' in the left navigation pane.
4. Click on 'Create Volume' to start the volume creation wizard.
5. Select the volume type, size, and availability zone.
6. Configure advanced settings, such as encryption and tags.
7. Review the volume details and create the volume.

Once the volume is created, you can attach it to an EC2 instance and use it as additional storage.

By leveraging storage services like S3 and EBS, you can securely store and retrieve your data in AWS, whether it's static files, databases, or application logs. These services offer high scalability, durability, and flexibility to meet your storage needs.

    s3Client.deleteObject(bucketName, "key");

    // Delete the bucket

    s3Client.deleteBucket(bucketName);
