AWS Beginner's Guide: How to Quickly Master the Basics and Applications of AWS

In the wave of modern cloud computing, Amazon Web Services (AWS) is undoubtedly one of the most popular cloud service platforms. Whether for startups or large enterprises, AWS offers a wealth of services to support their business operations. However, with the diversification of services, many beginners often feel confused when learning and using AWS. This article will provide you with a practical AWS beginner's guide to help you quickly master the basic knowledge and application skills of AWS.

What is AWS?

AWS is a cloud computing service platform launched by Amazon, providing over 200 services, including computing power, storage, databases, machine learning, and artificial intelligence. AWS allows users to use IT resources on demand anytime and anywhere, fundamentally changing the way software development and IT infrastructure operations are managed.

Core Services of AWS

Before starting to use AWS, it is crucial to understand its core services. Here are some commonly used AWS service introductions:

1. Amazon EC2 (Elastic Compute Cloud)

   • Provides scalable computing power, allowing users to launch virtual machines based on demand.

2. Amazon S3 (Simple Storage Service)

   • An object storage service suitable for storing and retrieving any amount of data.

3. Amazon RDS (Relational Database Service)

   • Manages and operates relational databases, supporting multiple database engines.

4. AWS Lambda

   • A serverless computing service that allows users to run code without managing servers.

5. Amazon CloudFront

   • A content delivery network (CDN) that accelerates the delivery of static and dynamic content.

How to Get Started with AWS?

Step 1: Create an AWS Account

1. Visit AWS Official Website.
2. Click on "Create a Free Account" in the upper right corner.
3. Fill in personal information and account settings as prompted.

Step 2: Understand the AWS Management Console

After logging in, you will enter the AWS Management Console. This is the center for managing all AWS services. Understanding the layout and functions of the console will help you use AWS more efficiently.

Step 3: Familiarize Yourself with Basic Concepts

• Regions and Availability Zones: AWS consists of multiple regions, each containing several availability zones. Choosing the right region can enhance the availability and performance of applications.
• IAM (Identity and Access Management): IAM allows you to manage users and permissions, ensuring security.
• Billing and Pricing: Pay-as-you-go is a significant feature of AWS; familiarizing yourself with AWS's billing model can help avoid unnecessary costs.

Practical Tips and Best Practices

1. Utilize the AWS Free Tier

AWS offers a free basic service tier for one year, including Amazon EC2 and Amazon S3. Make good use of these free resources during your learning period to reduce costs.

2. Participate in Community Events

As mentioned in Twitter discussions, joining AWS community events (such as AWS Community Day Pune) can provide opportunities for learning and networking. By participating in online or offline community events, you can exchange experiences with other users and gain more learning resources.

3. Learning and Certification

AWS provides a wealth of learning resources, including official documentation, online courses, and certification exams. Obtaining AWS certification can not only enhance your skills but also aid in career development.

4. Start with Small Projects

Beginners can start with simple small projects, such as deploying a simple website or application, to practice what they have learned.

• Example: Deploying a static website on EC2

# Create an EC2 instance
aws ec2 run-instances --image-id ami-0abcdef1234567890 --count 1 --instance-type t2.micro --key-name YourKeyPair --security-group-ids sg-0123456789abcdef0 --subnet-id subnet-0bb1c79de3EXAMPLE

# Connect to the instance
ssh -i "YourKeyPair.pem" ec2-user@
