Amazon S3 is a cloud storage service provided by AWS. It allows you to store and access any type of files or data over the internet. You can think of it as an online storage space where you can upload, download, and manage your files and data securely. S3 is highly scalable, meaning you can store as little or as much data as you need without worrying about running out of space. It is also designed to be highly durable, ensuring your data is safe and available whenever you need it.
Amazon S3 offers several Storage Classes designed for different data access patterns and cost requirements:
- S3 Standard: For frequently accessed data that needs fast retrieval, like website files, mobile app data, or frequently accessed analytics data.
- S3 Intelligent-Tiering: For data with unknown or changing access patterns. It automatically moves objects to the most cost-effective tier based on how frequently they are accessed.
- S3 Standard-IA: For long-lived data that is infrequently accessed, like backups or older logs. It has lower storage costs than S3 Standard but higher retrieval costs.
- S3 One Zone-IA: Similar to Standard-IA but stores data in a single Availability Zone, making it a lower-cost option for infrequently accessed data that doesn't require multi-AZ resiliency.
- S3 Glacier Instant Retrieval: For long-term storage of data that is rarely accessed, like backups or archives, but with millisecond retrieval times when needed.
- S3 Glacier Flexible Retrieval: For archiving data that doesn't need immediate access, with retrieval times ranging from minutes to hours. Ideal for long-term backups or data retention.
- S3 Glacier Deep Archive: The lowest-cost option for archiving data that is accessed once or twice per year, with retrieval times within 12 hours. Suitable for long-term data retention and compliance requirements
