Creación de instancias en AWS

How to create an instance on AWS?

Configure your cloud environment correctly and maximize the use of available resources at your disposal. Creating an instance on AWS is the first step towards managing servers in the cloud. This process will allow you to deploy applications and manage services, taking advantage of the advanced features of Amazon Web Services. Here's how to do it easily and effectively, from initial access to final configuration.

What is the Easy2 dashboard?

Easy2 is a user interface that makes it easy to create and manage AWS cloud instances. Its dashboard is mainly divided into two sections:

• Sidebar: Includes options for creating and viewing resources such as instances, instance types, AMIs, volumes, and IP addresses.
• Main content: Displays a summary of the number of instances you have running, the IPs created and assigned, as well as the "Launch Instance" button to start the process of creating an instance.

How to choose the name and operating system for your instance?

1. Assign a name: Once you start the process, assign a name that easily identifies your instance. In this case, the recommended name is "Python Server".

2. Select the operating system: Select Ubuntu as the operating system, version 24, since it is compatible with the commands that will be used.

3. Check the details: Be sure to check important details such as the username, which will be required to connect to the server.

How to choose the instance type and create a key?

• Instance type: Select an instance type that suits the needs of your application. For example, use the P2 Micro, which offers one CPU and one gigabyte of memory.
• Create a new key: Create a key pair, using the PEM format for Linux systems and the PPK format if you are on Windows. Name it, for example, "Python server key".

# Create new keycreate new key pair: "Python server key", format: PEM or PPK

What is the importance of the network configuration?

The network configuration is crucial to define how your instance will connect to the Internet and how other services will be able to interact with it:

• Allow IP connections: initially, allow access from any IP for ease of development. However, it is preferable to limit access.
• HTTPS/HTTP configuration: Enable HTTP traffic initially, and once the security certificate is ready, enable HTTPS traffic.

Storage configuration?

The choice of storage ensures adequate performance according to the project:

• Hard disk type: opt for a GP3 type SSD for its improved speed.
• Storage size: Select a size of at least 20 GB to ensure sufficient space.

How to secure a static IP with Elastic IPs?

Using Elastic IPs allows your server to keep the same IP, even after reboots:

• Create and associate an Elastic IP: Associate the Elastic IP to your instance to maintain connection consistency.

# Assign an Elastic IPactions: associate, select instance, and check the option not to delete it if the instance is running.

How to review the security settings?

Check the security settings to define which ports are accessible:

• Inbound rules: configure access on ports 22 (SSH), 80 (HTTP), and 443 (HTTPS).
• Outbound rules: Make sure that outbound connections have sufficient accessibility.

How to connect to your instance?

Facilitate access by correctly configuring credentials and establishing an SSH connection. You can execute commands and perform necessary configurations from the terminal.

# Command to view connectivityping google.com

How to accept the challenge?

Test your skills by creating a new instance and configuring an Nginx server as a personal challenge. Use the acquired knowledge to make it work efficiently.

# Install Nginxsudo apt updatesudo apt install nginx

With these instructions, you will be ready to create and manage an instance on AWS, thus maximizing the potential of your cloud projects. Keep on exploring and encouraging yourself to take on new technological challenges!
