Study Notes
EC2
- Virtual Machines: EC2 (Elastic Compute Cloud) provides virtual machines (instances) with various operating systems, including Windows, Linux, and macOS.
- Instance Types: Offers a range of instance types, including General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and Accelerated Computing.
-
Security: Provides security features, such as:
- Security Groups (firewall rules)
- Key Pairs (secure login)
- IAM Roles (access control)
- Pricing: Offers On-Demand, Reserved, and Spot instances with varying pricing models.
S3
- Object Storage: S3 (Simple Storage Service) is an object storage service that stores data as objects in buckets.
-
Key Features:
- Highly durable and available storage
- Scalable and flexible storage
- Supports data encryption and access control
-
Storage Classes: Offers different storage classes, including:
- Standard
- Infrequent Access (IA)
- Archive
- Deep Archive
- Pricing: Pricing based on storage, requests, and data transfer.
Lambda
- Serverless Computing: Lambda is a serverless computing service that runs code without provisioning or managing servers.
-
Key Features:
- Event-driven architecture
- Supports Node.js, Python, Java, Go, and C# languages
- Automatic scaling and high availability
- Use Cases: Suitable for real-time data processing, image processing, and API backend services.
- Pricing: Pricing based on the number of executions, memory allocation, and execution time.
CloudFormation
- Infrastructure as Code: CloudFormation is a service that allows you to use templates to define and deploy infrastructure as code.
-
Key Features:
- Supports a wide range of AWS services
- Version control and change management
- Automatic rollbacks and updates
- Use Cases: Suitable for DevOps, CI/CD pipelines, and infrastructure automation.
- Pricing: No additional cost, but resources created by CloudFormation incur standard AWS service charges.
DynamoDB
- NoSQL Database: DynamoDB is a fast, fully managed NoSQL database service that supports document and key-value data models.
-
Key Features:
- High performance and low latency
- Supports secondary indexes and caching
- Automatic scaling and backup
- Use Cases: Suitable for large-scale applications, real-time analytics, and IoT data processing.
- Pricing: Pricing based on read and write capacity, storage, and data transfer.
