Creating an AWS VPC - The Core of Cloud Networking

 Title: Creating an AWS VPC - The Core of Cloud Networking

Introduction:

AWS VPC (Virtual Private Cloud) is a fundamental concept in AWS that allows you to configure your network environment. While it may seem like a concept you can overlook if you're only creating a single EC2 instance for a web service (since default values are in place), understanding VPC becomes essential for effectively utilizing AWS.

According to the AWS website, VPC is described as follows:

"Virtual Private Cloud (VPC) is a user's private virtual network within AWS. VPC is logically isolated from other virtual networks in the AWS Cloud. It enables you to run AWS resources, such as Amazon EC2 instances, within your own virtual network." - What is Amazon VPC? (URL: https://docs.aws.amazon.com/vpc/latest/userguide/what-is-amazon-vpc.html)

Although AWS VPC provides defaults, the underlying VPC is a shared space where instances (servers) are logically separated from other unused instances. While VPC itself provides logical network isolation, you can think of it as creating a separate space for the instances you use, distinct from the shared environment.

Now, let's dive deeper into the process of creating an AWS VPC and its key components.

1. Sign in to the AWS Console:

To begin creating an AWS VPC, sign in to the AWS Console. If you don't have an AWS account, create one on the AWS website and then proceed with logging in.

2. Navigate to the VPC Dashboard:

Once logged in to the AWS Console, navigate to the VPC Dashboard. The VPC Dashboard allows you to create and manage VPCs effectively.

3. Create a VPC:

In the VPC Dashboard, click on the "Create VPC" button to initiate the creation of a new VPC. Provide a name for your VPC and specify the CIDR (Cloud IP address range). The CIDR represents the range of IP addresses used within the VPC and should be unique.

4. Create Subnets:

After creating the VPC, you need to create subnets. Subnets define network segments within the VPC. Each subnet should have a unique CIDR range and must be within the CIDR range of the VPC.

5. Connect an Internet Gateway:

To connect your AWS VPC to the internet, you need to associate an internet gateway with the VPC. This enables instances within the VPC to communicate with the internet.

6. Configure Routing Tables:

Routing tables determine the path for packet transmission within the VPC. A default routing table is automatically created when you create a VPC, but you may need to create custom routing tables based on your requirements.

7. Configure Security Groups:

Security groups are used to define security rules for instances. They control inbound and outbound traffic for instances and enforce security policies.

8. Test the VPC:

Once you have successfully created the VPC, test its functionality by launching instances and verifying that they are operating correctly within the VPC. The IP addresses assigned to the instances should fall within the CIDR range of the VPC.

[AWS] Setting Up AWS CLI Connection on Windows

 "Setting Up Ubuntu on Windows Store for AWS CLI Configuration"

Note: I am assuming that you are referring to the process of installing Ubuntu from the Windows Store and using it for AWS CLI configuration on a Windows machine.

Currently, I'm studying and experimenting with AWS, including launching EC2 instances and various other tasks. While following a book, I came across the process of configuring AWS CLI using the command line interface. On macOS, it's as simple as opening the Terminal and proceeding. However, on Windows, there are several installations and settings required, which can be quite cumbersome.

Instead of using the default Windows terminal (cmd), I found it quite inconvenient to work with PowerShell (in administrator mode). Hence, I will document an alternative method using Ubuntu, which can be downloaded and installed from the Windows Store.

Please note that I have followed online tutorials and guides, so there may be some inaccuracies in my instructions.

1. Installing Ubuntu from the Windows Store

Please refer to the following URL for detailed instructions: [Link to Microsoft Documentation](https://docs.microsoft.com/en-us/windows/wsl/install-win10)

1) Launch PowerShell in administrator mode.

2) Enter the following command:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

3) Reboot your system.

4) Go to the Microsoft Store and search for Ubuntu.

- Perform a search for "Ubuntu" within the store.

- Download and install the Ubuntu application.

(The documentation might mention logging in, but you can proceed with the installation without logging in.)

Please note that the above instructions are for installing Ubuntu from the Windows Store, specifically for configuring AWS CLI.

5) The installation will be completed in a few minutes.

2. Installing Python and PIP

To use AWS CLI, you need to have Python and PIP installed.

1) Launch Ubuntu.

2) When running Ubuntu for the first time, it will prompt you to create a user account.

3) Proceed with Python installation.

 Please refer to the following URL for detailed instructions: [Link to AWS Documentation](https://docs.aws.amazon.com/cli/latest/userguide/install-linux-python.html)

 - Check the installation: python3 --version

 If Python is not installed: sudo apt install python3

4) Install PIP.

 - Install Python script: curl -O https://bootstrap.pypa.io/get-pip.py

 - Install necessary utilities for executing the Python script. It is recommended to update all packages before proceeding to avoid any potential errors. If you proceed without updating, errors may occur.

     sudo apt update

     sudo apt-get install python3-distutils

   - Install PIP: python3 get-pip.py --user

5) Configure the PATH.

   When installing PIP, you may encounter the following warning related to PATH. As the warning suggests, it is necessary to set the PATH accordingly.

  export PATH=~/.local/bin:$PATH

  source ~/.profile

  pip --version

   Running the above commands should display the version of pip without any errors, indicating a successful configuration.

6) Install AWS CLI.

   Please refer to the following URL for detailed instructions: [Link to AWS Documentation](https://docs.aws.amazon.com/cli/latest/userguide/install-linux.html)

   pip install awscli --upgrade --user

   aws --version

   After a successful installation, running the command "aws --version" should display the installed version of AWS CLI.

Please note that the above instructions are for installing Python, PIP, and AWS CLI on Ubuntu within the Windows environment.

Warrior's History, 'The Admiral: Roaring Currents': A Review(K-Movie, K-Culture)

K-Movie

In 1597, the sixth year of the Imjin War, Joseon was in a state of turmoil due to a prolonged war. With the Japanese army advancing towards Hanyang at an alarming speed, the nation faced the threat of collapse. General Yi Sun-sin (played by Choi Min-sik), who had been wrongly accused and dismissed from his position, is reinstated as the Chief of Naval Operations.

However, all that remains for him are soldiers who have lost their morale, and frightened citizens, as well as 12 ships. The last hope, the Turtle Ship, is also burnt down. When the mercenary Kurushima (played by Ryu Seung-ryong), known for his cruel nature and outstanding military tactics, becomes the leader of the Japanese army, Joseon becomes even more chaotic.

As more than 330 Japanese warships gather, and everyone senses the looming defeat in the face of overwhelming numbers, General Yi Sun-sin leads just 12 ships towards the sea of Myeongnyang...!

A great battle that changed history begins between 12 Joseon ships and 330 Japanese warships.

Asserting Sovereignty: Why Dokdo is Undoubtedly Korean Territory

 Dokdo is a small group of islands located in the East Sea (Sea of Japan) and is claimed by both South Korea and Japan. South Korea has been occupying the islands since 1954 and has been actively maintaining the territory ever since.

Historically, Dokdo has been recognized as Korean territory since the sixth century and has been marked as such on official Korean maps since the 17th century. Japan's claim to Dokdo stems from its colonial occupation of Korea from 1910 to 1945, during which time Japan attempted to assimilate Dokdo into its territory.

The dispute over Dokdo has been a contentious issue between South Korea and Japan for many years, and there have been various diplomatic and legal efforts to resolve it. Despite this, tensions remain high, and the issue continues to be a source of political and diplomatic friction between the two countries.

The importance of Dokdo to South Korea is not only based on the island's historical significance but also its strategic location in the East Sea. The area surrounding Dokdo is rich in marine resources, including fish, crab, and squid, and is a valuable fishing ground for South Korean fishermen.

In addition to its economic significance, Dokdo holds a special place in the hearts of many Koreans, who view it as a symbol of their nation's sovereignty and independence. As such, any attempt to compromise South Korea's claim to Dokdo is likely to be met with fierce resistance from the Korean people.
