Amazon EBS is a block storage service provided by AWS for EC2 instances.

It is mainly used to store operating systems, application data, databases, and persistent storage for cloud servers.

What Is Amazon EBS?

Amazon EBS (Elastic Block Store) is a block-level storage service designed for Amazon EC2.

EBS volumes work like virtual hard disks attached to EC2 instances.

Why Is EBS Important?

EBS provides:

• persistent storage

• high availability

• scalability

• backup support

• fast performance

Types of EBS Volumes

General Purpose SSD (gp3)

Balanced price and performance.

Provisioned IOPS SSD

High-performance workloads like databases.

Throughput Optimized HDD

Large data workloads.

How EBS Works with EC2

An EBS volume is created separately and attached to an EC2 instance.

The EC2 instance uses the EBS volume like a physical hard disk.

Steps to Attach EBS to EC2

Step 1

Create EC2 instance.

Step 2

Open EBS volumes section in AWS console.

Step 3

Create new EBS volume.

Step 4

Select:

• size

• volume type

• availability zone

Step 5

Attach volume to EC2 instance.

Step 6

Login to EC2 and mount the volume.

Benefits of EBS

• Persistent storage

• Snapshot backup support

• High durability

• Easy scalability

• Encryption support

Real-World Example

A production application running on EC2 stores application data and logs inside EBS volumes for persistent storage.

Conclusion

Amazon EBS is an important AWS storage service used with EC2 instances to provide scalable and persistent block storage.

Amazon EC2 is one of the core AWS services used to create and manage virtual servers in the cloud.

It allows developers and organizations to run applications without purchasing physical hardware.

What Is Amazon EC2?

Amazon EC2 (Elastic Compute Cloud) is a cloud computing service provided by AWS.

It provides scalable virtual servers called EC2 instances.

These instances can run:

• applications

• websites

• APIs

• databases

• backend services

Why Is EC2 Important?

EC2 helps organizations:

• avoid physical server management

• scale applications easily

• deploy infrastructure quickly

• reduce operational costs

Key Features of EC2

Scalability

Increase or decrease resources anytime.

Flexibility

Choose operating systems, CPU, RAM, and storage.

Pay-As-You-Go Pricing

Pay only for resources you use.

Security

Use Security Groups and IAM for access control.

Common EC2 Components

• AMI (Amazon Machine Image)

• Instance Types

• Security Groups

• EBS Volumes

• Key Pairs

Real-World Example

A company hosting a web application can deploy its backend application on EC2 instances instead of maintaining physical servers.

Benefits of EC2

• Fast deployment

• Global availability

• High scalability

• Cost optimization

• Easy infrastructure management

Conclusion

Amazon EC2 is one of the most important AWS services used for cloud computing and scalable infrastructure management.

Cloud computing has changed how modern applications are built and deployed. AWS is one of the most popular cloud platforms used by startups, enterprises, and developers worldwide.

What Is AWS?

AWS (Amazon Web Services) is a cloud computing platform provided by Amazon.

It offers services like:
