- 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
