B. Scalable object storage
C. Host web applications
D. Large-scale data processing
Answer
B. Scalable object storage
Explanation
The primary purpose of Amazon S3 is to provide scalable object storage, with data durability and availability for a wide range of use cases.
Amazon Simple Storage Service (Amazon S3) is a cloud-based object storage service designed to provide industry-leading scalability, durability, and availability for storing and managing data. Its primary purpose is to store data as objects within “buckets,” making it ideal for a wide range of use cases such as:
- Data lakes for analytics
- Backup and disaster recovery
- Content distribution
- Big data processing
- Archiving
Amazon S3 is not designed to run serverless functions (which is the role of AWS Lambda), host web applications (handled by services like AWS Elastic Beanstalk or EC2), or perform large-scale data processing directly (handled by tools like Amazon EMR or AWS Glue). Instead, it serves as the foundational storage layer that integrates seamlessly with these services to support their operations.
Key features of Amazon S3 include:
- Scalability: Virtually unlimited storage capacity.
- Durability: 99.999999999% (11 nines) durability, ensuring data safety.
- Cost-efficiency: Multiple storage classes tailored to access patterns (e.g., Standard, Glacier).
- Security: Encryption options and fine-grained access controls.
Thus, the correct answer is B. Scalable Object Storage, as it captures the core functionality and purpose of Amazon S3.
