1. What is AWS?
AWS is a cloud computing platform provided by Amazon. It allows businesses and developers to access and manage computing power, storage, databases, and other services over the internet, instead of relying on physical hardware.
2. AWS Core Services
AWS offers a variety of services, but here are the most common ones:
- EC2 (Elastic Compute Cloud): Virtual servers where you can run your applications.
- S3 (Simple Storage Service): Scalable cloud storage for your files and data.
- RDS (Relational Database Service): Managed relational databases like MySQL, PostgreSQL, and others.
- Lambda: Run code without provisioning or managing servers (serverless computing).
- VPC (Virtual Private Cloud): A private network to control your resources securely in the cloud.
3. Pricing Model
AWS follows a pay-as-you-go model, meaning you only pay for what you use. You can scale up or down based on demand, which helps save costs.
4. Benefits of AWS
- Scalability: You can easily scale up or down based on traffic or demand.
- Security: AWS provides encryption, firewalls, and security protocols to protect your data.
- Flexibility: You can choose from a wide range of services and tools tailored to your needs.
5. How to Start Using AWS
- Create an AWS Account: Visit the AWS website and sign up for an account.
- Launch EC2 Instances: Start with creating virtual servers using EC2.
- Store Data in S3: Upload and store your data in S3.
- Use IAM (Identity and Access Management): Manage who can access your AWS resources and set permissions.
6. Common Use Cases
- Web Hosting: Host your websites on EC2 and store media on S3.
- Big Data Processing: Use services like EMR (Elastic MapReduce) for large-scale data processing.
- Mobile Applications: Build and deploy mobile apps using AWS services.
By understanding these basic concepts, you can get started with AWS and use it for various applications like hosting, storage, and computing.
