Today's AWS hands-on practice was a big win for me.

I successfully launched my first Amazon EC2 instance, learned how to choose an Amazon Machine Image (AMI), selected the right instance type, created a key pair, and finally terminated the instance—all by myself.

At first, I got stuck because I couldn't stop or terminate the instance. After troubleshooting and learning what I was missing, I figured it out. I even repeated the entire process without following a video, just to make sure I truly understood it.

One thing I'm learning on this cloud journey is that hands-on practice makes all the difference. Reading and watching tutorials are important, but actually using the AWS Management Console is where the real learning happens.

I'm taking this journey one step at a time, and every small milestone reminds me that consistency beats perfection.

On to the next lesson: AWS Security Groups.

One of the things I learned in my AWS Cloud journey is that Amazon S3, Amazon EBS, and Amazon EFS are all storage services, but they are designed for different purposes.

Amazon S3 (Simple Storage Service) is object storage. It is used to store files like photos, videos, documents, backups, and application data. It is highly durable and can be accessed from anywhere over the internet.

Amazon EBS (Elastic Block Store) is block storage. It works like a hard drive attached to an Amazon EC2 virtual server. It is ideal for operating systems, databases, and applications that need fast and consistent performance.

Amazon EFS (Elastic File System) is file storage. It allows multiple EC2 instances to access the same files at the same time. It is a great choice for shared folders, web applications, and workloads that require multiple servers to work with the same data.

In simple terms:
Amazon S3 is for storing files.
Amazon EBS is a hard drive for one virtual server.
Amazon EFS is a shared folder that many virtual servers can use together.

Understanding these differences makes it easier to choose the right AWS storage service for different workloads.

Think of Amazon S3 storage classes like choosing different types of rooms to keep your belongings. The room you choose depends on how often you need to access your files and how much you want to spend.

S3 Standard
This is for files you use often. It gives fast access and is great for websites, apps, and active data.

S3 Intelligent-Tiering
This is the smart option. It automatically moves your files between storage levels depending on how often they are used, helping reduce cost without needing manual work.

S3 Standard-Infrequent Access (Standard-IA)
This is for files you don’t use every day but still want quick access to when needed. A good example is backups.

S3 One Zone-Infrequent Access (One Zone-IA)
Similar to Standard-IA, but stores data in one location instead of multiple locations. It costs less but has lower resilience.

S3 Glacier Instant Retrieval
For data you rarely need but still want available quickly when requested.

S3 Glacier Flexible Retrieval
Designed for archived data that is not needed immediately. Retrieval takes minutes to hours and costs less.

S3 Glacier Deep Archive
The lowest-cost option for long-term storage. Best for files that may stay untouched for years, like old records or compliance documents.

The main difference between all these storage classes is simple: frequency of access, speed of retrieval, and cost.

The less often you need your data, the lower the storage cost can become.

Amazon Simple Storage Service (Amazon S3)

Amazon S3 is a cloud storage service from Amazon Web Services (AWS). It helps individuals and businesses store, manage, and access files from anywhere using the internet.

📌 *Benefits of Amazon S3*

• Secure storage for files and data

• Easy to scale up as your storage needs grow

• High durability and reliability

• Access your data anytime, anywhere

• Cost-effective because you pay for what you use

📂 *Container (Bucket)*

A bucket is like a digital container that holds your files in Amazon S3. Before uploading files, you first create a bucket.

📄 *Object*

An object is the actual file stored in Amazon S3, such as an image, video, document, or audio file. Each object also contains information about the file (metadata).

🪣 *Bucket*

A bucket is the main storage space where objects are organized and managed inside Amazon S3.

🔄 *Data Lifecycle Management*

This feature helps automatically manage files over time. For example, old files can move to cheaper storage or be deleted automatically to reduce cost.

🔐 *Encryption*

Encryption protects your stored data by converting it into a secure format so only authorized users can access and read it.

Cloud computing is not just about saving files, It’s also about security, management, and efficiency.

💾 What is Amazon Elastic Block Store (EBS)?

When learning AWS, one storage service you will hear often is Amazon Elastic Block Store (EBS).

Think of Amazon EBS like the hard drive inside your laptop — but instead of being inside a physical computer, it works in the cloud.

EBS is used together with Amazon EC2 (virtual servers). While EC2 runs your applications and websites, EBS stores the files, operating system, and important data.

Why is Amazon EBS useful?

✅ Persistent storage – Your data remains available even after restarting your server.

✅ Scalable – You can increase storage when your project grows.

✅ Fast performance – Helps applications and websites run smoothly.

✅ Backup support – You can create snapshots and restore data when needed.

✅ Secure – AWS provides security features to help protect stored information.

Simple example:
Imagine you own an online store.

EC2 = The shop building
EBS = The storage room where all your products and important items are kept.

Without storage, the server has nowhere to keep data.

☁️ Understanding Amazon EC2 Instance Store vs Amazon Elastic Block Store (EBS)

When learning AWS, one thing that can be confusing at first is storage attached to virtual servers. Two common options are **Amazon EC2 Instance Store** and **Amazon Elastic Block Store (EBS)**.

Think of it this way:

🖥️ **Amazon EC2 Instance Store (Temporary Storage)**
This is storage that comes directly with the EC2 server.

Imagine renting a laptop for a project. You save files on that laptop, but once you return it, everything disappears.

That is how EC2 Instance Store works.

Features:
• Very fast performance
• Good for temporary files and cache
• Data is lost if the instance stops, terminates, or fails
• Best for short-term data processing

Example:
You are editing a video and only need temporary working files. Losing those files later is not a problem.

💾 **Amazon Elastic Block Store (EBS) – Permanent Storage**
EBS acts more like an external hard drive connected to your EC2 server.

Even if you stop your EC2 instance, your data remains safe and can still be attached again.

Features:
• Persistent storage (data stays)
• Can create backups (snapshots)
• Can increase storage size when needed
• Suitable for databases, websites, and business applications

Example:
You run an online shop. Customer records and website files must remain available even after the server restarts.

👉 Simple difference:
EC2 Instance Store = Temporary storage
Amazon EBS = Long-term storage

In real-world cloud projects, EBS is commonly used because most applications need their data to stay safe.

🌍 Understanding AWS Global Networking

When people hear “cloud computing,” they often imagine data floating somewhere in the sky. But in reality, cloud services depend on something powerful happening behind the scenes: networking.

AWS Global Networking is what helps applications, websites, and services reach users quickly and reliably across the world.

Think of it like a transportation system.

You can have the best app in the world, but if users can’t reach it quickly, they won’t enjoy using it.

Here are some important parts of AWS Global Networking:

🚦 Edge Networking Services
Edge networking brings services closer to users instead of making every request travel to one central server.

Imagine ordering food. Instead of the restaurant cooking and delivering from one city every time, small delivery stations are placed closer to customers to speed things up.

The goal:
✔ Faster performance
✔ Lower delays
✔ Better user experience

🌐 Amazon Route 53 – The Internet’s Smart Navigator
Route 53 works like the internet’s address book.

People type website names because nobody wants to memorize long IP addresses.

Route 53 receives that request and directs users to the correct destination.

Example:
You type a website name → Route 53 finds where that website lives → You arrive there.

⚡ Amazon CloudFront – Fast Content Delivery
CloudFront helps websites load faster.

Instead of downloading images, videos, and website files from one faraway server every single time, CloudFront stores copies closer to users around the world.

Result:
• Faster websites
• Better streaming
• Smoother user experience

🛣 AWS Global Accelerator – The Faster Route
Global Accelerator improves how users reach applications.

Rather than depending completely on unpredictable internet paths, it helps traffic move through AWS’s optimized global network.

This means:
• Lower latency
• Better availability
• Faster connections for users worldwide

Cloud networking is not only about storing data in the cloud — it’s also about delivering experiences quickly, reliably, and at scale.

Every fast-loading website and smooth application experience often starts with strong networking architecture behind the scenes.

Understanding Containers in Cloud Computing (AWS) — Simple Explanation

When people hear *containers*, it can sound complicated, but the idea is actually simple.

Think of a container like a "packed lunch box for an application"

Everything the application needs to run code, libraries, settings, and dependencies — is packed together in one container. That means the app can work the same way anywhere without the usual “it works on my laptop but not on the server” problem.

With AWS, containers make it easier to build, deploy, and manage applications faster and more efficiently.

Some AWS container services include:

*Amazon ECS (Elastic Container Service)* Helps you run and manage containers without worrying too much about the infrastructure.

*Amazon EKS (Elastic Kubernetes Service)*
A managed service for running Kubernetes on AWS for larger and more complex container environments.

WS Fargate, Lets you run containers without managing servers at all.

Why do companies love containers?
✅ Faster deployment
✅ Consistent performance across environments
✅ Easier scaling
✅ Better use of resources
✅ Supports modern application development

Containers are becoming a big part of cloud computing because they help businesses move quickly while keeping applications reliable.

☁️ AWS Lambda made simple!

Think of AWS Lambda as a smart helper that runs your code only when needed — no servers to manage, no extra setup.

Instead of keeping a computer running all day, Lambda automatically starts when an event happens (like uploading a file, clicking a button, or receiving data), does the work, and stops.

Why people love it:
✅ No server management
✅ Automatic scaling
✅ Pay only for what you use
✅ Faster application development

Build more. Manage less. That’s the power of AWS Lambda.

Different ways messages can be passed on cloud computing.

📩 *Amazon Simple Queue Service (SQS)*
Amazon SQS is a messaging service that helps different applications communicate smoothly by sending, storing, and receiving messages in a queue. It makes systems more reliable because tasks can wait in line and be processed when ready.

📢 *Amazon Simple Notification Service (SNS)*
Amazon SNS is a notification service used to send messages instantly to many users or applications at once through email, SMS, mobile notifications, and more. It helps businesses share updates quickly and automatically.

In simple terms:
➡️ SQS = Messages wait in a line (Queue)
➡️ SNS = Messages are broadcast instantly (Notifications)
