Amazon Simple Storage Service (Amazon S3) is a cloud-based object storage service provided by Amazon Web Services (AWS). It is designed for high scalability, data availability, security, and performance, enabling users and organizations to store and retrieve any amount of data from anywhere on the internet.
Key Features
• Object Storage Model: S3 stores data as objects within buckets. Each object consists of the data itself, metadata, and a unique key (identifier).
• Buckets: A bucket is a logical container for storing objects. Each bucket name must be globally unique, and you can create multiple buckets in different AWS regions.
• Scalability and Performance: S3 automatically scales to accommodate virtually unlimited data, supporting storage from gigabytes to exabytes with high performance and low latency.
• Durability and Availability: S3 is engineered for 99.999999999% (11 nines) durability and 99.99% availability, with data automatically replicated across multiple devices and facilities within an AWS region.
• Security and Access Control: Data in S3 is private by default. Access can be managed using AWS Identity and Access Management (IAM) policies, bucket policies, access control lists (ACLs), and S3 Access Points. S3 supports encryption and auditing for compliance and security.
• Storage Classes: S3 offers multiple storage classes for different use cases and cost requirements, such as S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA (Infrequent Access), S3 One Zone-IA, S3 Glacier, and S3 Glacier Deep Archive.
• Data Management: S3 provides features like versioning, lifecycle policies, and event notifications to help manage data efficiently and automate transitions between storage classes
