Today, we are talking about adding storage using AWS's Elastic Block Store, or EBS. Can anyone tell me what EBS is?
I think EBS stands for Elastic Block Store. Itβs where we keep data in the cloud, like a hard drive, right?
Exactly, Student_1! EBS acts like a physical hard drive in the cloud where data persists even after the instance is stopped. What are some benefits of using EBS?
I heard it's flexible! You can attach and detach it from instances as needed.
Great point! Flexibility is one of the key attributes. EBS volumes also help maintain performance for applications. Can you think of a use case where persistent storage would be critical?
Like if you were running a database, you'd want the data to stay even if the server was stopped.
Exactly! Databases are a key example. Now, can anyone summarize the main functions of EBS?
It's for storing data, it persists beyond instance life cycles, and it's flexible.
Well done, everyone! Those are the main points about EBS.
Attaching EBS Volumes to EC2 Instances

In our last session, we discussed the basics of EBS. Now, letβs talk about how to attach an EBS volume to your EC2 instance. Whatβs the first step?
Choosing an AMI?
Not quite! First, you need to create or select an existing EBS volume. What are some volume types you can select from?
Thereβs general-purpose SSD and provisioned IOPS SSD, right?
Correct! After selecting the volume type, you can add it in the configuration section for storage. What do you think happens after this?
You need to tag it to keep it organized?
Exactly! Tags help manage your resources better. Now, can anyone tell me why itβs essential to add tags?
So you can easily locate volumes based on their purpose or project?
Spot on! Remember, good organization saves time and resources. Letβs recap: What are the steps to add storage?
Choose the EBS volume type, configure it, and then tag it.
Perfect summary!
Managing EBS Volumes

Now letβs learn how to manage EBS volumes. What happens to data on an EBS volume when you stop or terminate the instance?
If you stop the instance, the data stays, but if you terminate, the data is lost if not configured to delete on termination.
Right! Itβs vital to understand the distinction. How can you detach and attach EBS volumes?
You can do that through the AWS console or CLI, right?
Yes, the AWS console and CLI are both excellent ways to manage your EBS volumes. Why might you want to detach a volume?
To attach it to another instance or to troubleshoot issues with it.
Exactly! Finally, can anyone explain the importance of performance monitoring for EBS?
Monitoring helps us see if we're getting the performance we need and troubleshoot if there's a problem.
That's an excellent point, Student_1! Regular monitoring ensures efficient use of resources. Letβs summarize what we learned today on managing EBS volumes.
Introduction & Overview

Quick Overview
Standard
Explaining the process of adding storage to EC2 instances, this section emphasizes Elastic Block Store (EBS) as a persistent storage solution that enhances data management for applications running in the cloud. Students will learn how to attach EBS volumes to their EC2 instances, the benefits of persistent storage, and how tags help in organizing their cloud assets.
Detailed
Detailed Overview of Adding Storage
In the context of AWS and EC2 instances, storage is primarily managed through Elastic Block Store (EBS). EBS provides persistent block storage that remains intact even when instances are stopped or terminated. Hereβs a breakdown of the procedure to add storage:
- Select EBS Volumes: EBS acts like a hard drive in the cloud. It allows users to detach volumes from one EC2 instance and attach them to another, making it flexible for various applications.
- Volume Types: EBS offers several volume types optimized for different use cases, including general-purpose SSDs and provisioned IOPS SSDs for demanding applications.
- Tagging for Organization: Tags are essential for managing resources. By assigning key-value pairs (like Name=WebServer1), users can easily organize, filter, and find their instances or volumes.
- Persistent Data: Data stored in EBS volumes is retained independently from instance life cycles, ensuring reliability for data-intensive applications.
- Connections and Performance: EBS volumes can increase the overall performance of applications running on EC2 by providing fast and reliable storage.
Thus, adding and managing storage properly is crucial for effectively running applications in the AWS cloud environment.

Attach Elastic Block Store (EBS) volumes. EBS acts like a hard drive and persists beyond instance lifecycle.
Detailed Explanation
In this step, you will attach Elastic Block Store (EBS) volumes to your EC2 instance. EBS volumes provide block-level storage that allows your instance to store data similarly to a physical hard drive. One significant advantage of EBS is that it persists even after the instance is stopped or terminated, making it ideal for scenarios where you need to maintain data integrity, such as database storage or file systems.
Examples & Analogies
Think of an EC2 instance like a laptop, and the EBS volume is an external hard drive attached to it. Even if you shut down your laptop (the instance), you can still access the files on the external hard drive (the EBS volume) whenever you power it back up.

Chapter Content
EBS acts like a hard drive and persists beyond instance lifecycle.
Detailed Explanation
EBS volumes serve as durable storage that remains available regardless of the lifecycle of your EC2 instance. This means that data stored on an EBS volume can be retained and used after the EC2 instance is stopped, rebooted, or terminated. This feature is critical for applications that rely on consistent data storage, such as content management systems, databases, and even simple file storage needs.
Examples & Analogies
Consider EBS as a filing cabinet in an office. Even when you shut the office down for the night (much like stopping your EC2 instance), the cabinet (EBS storage) remains intact with all the important documents (data inside) ready to be accessed when the office reopens.
Key Concepts
-
Elastic Block Store (EBS): Persistent storage for EC2, retaining data beyond instance lifecycle.
-
Volume Types: Different storage configurations are available based on performance needs.
-
Tags: Key-value pairs help organize and filter AWS resources.
Examples & Applications
An EBS volume can be attached to an EC2 instance to hold a MySQL database, which keeps all data intact during instance stops.
Developers can tag EBS volumes according to projects (e.g., 'ProjectX_DB'), allowing better management.
