Processing in the Cloud
,S3 (Simple Storage Service)
• S3 (Simple Storage Service) in cloud computing refers to
Amazon Simple Storage Service (AWS S3), a highly scalable,
secure, and durable object storage service for storing and
retrieving any amount of data from anywhere over the
internet, using data organized as objects in buckets, ideal for
backups, websites, data lakes, and apps, offering different
storage classes for cost optimization.
,Key Concepts
• Object Storage: Stores data as objects (files +
metadata) in a flat structure, unlike traditional
file systems, allowing virtually unlimited scale.
• Buckets: Containers for your objects, with their
own settings for access control and region.
• Objects: The actual data (images, videos,
documents) you store, with individual size limits
(up to 5 TB).
, Core Features & Benefits
• Scalability & Durability: Designed for extreme durability (11
nines) and virtually unlimited storage capacity.
• Accessibility: Store and retrieve data from any device,
anywhere, via APIs.
• Cost-Effective: Offers various storage classes (e.g., Standard,
Glacier) to match data access frequency and reduce costs.
• Security: Fine-grained access controls (IAM, bucket policies)
and encryption.
• Integration: Works seamlessly with other AWS services for
analytics (Athena, Redshift) and applications.
