S3 also has a 99.99999999999 durability rate (famously known as the 11 9’s), which makes it highly reliable and secure.

Here are the main features of Amazon S3

Storage Management and Monitoring

Amazon S3 has a non-hierarchical structure and various management tools that assist business of all sizes to use their data more efficiently. By using prefixes, objects that are stored in S3 buckets can be shared seamlessly which improves collaboration between teams. With comprehensive reports like the S3 Inventory report, all stored objects can be easily categorized and retrieved through tags and metadata and encryption status.

Storage Analytics and Insights:

Gain valuable insights about how and when to move data into the appropriate storage class through the S3 Storage Class Analysis. This analysis uses storage access patterns to provide businesses with the insights needed to drastically improve their S3 Lifecycle policies, which reduces the overall costs. The S3 Storage Lens offers visibility across the organization to monitor activity trends, provide actionable recommendations, improve cost efficiency, and assist in the application of best practices for data protection.

Amazon S3 Storage Classes

Amazon S3 has tailor-made different classes that can be applied to meet your unique business requirements. It also enables users to manage data throughout its lifecycle, where setting up a S3 Lifecycle policy, data transfer can be automated between different classes.

  • S3 Standard for general-purpose storage of frequently accessed data
  • S3 Intelligent-Tiering for data with unknown or changing access patterns
  • S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for long-lived, but less frequently accessed data
  • Amazon S3 Glacier (S3 Glacier) and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation.

Access Management and Security:

Amazon S3 has various tools that can grant access to other users like,

  • AWS Identity and Access Management (IAM) to create users and manage their respective access
  • Access Control Lists (ACLs) to make individual objects accessible to authorized users
  • Bucket policies to configure permissions for all objects within a single S3 bucket
  • S3 Access Points to simplify managing data access to shared data sets by creating access points with names and permissions specific to each application or sets of applications
  • Query String Authentication to grant time-limited access to others with temporary URLs

Amazon S3 also offers a wide range of security features that can be used to block any unauthorized users from accessing your valuable data. With encryption from both server-side encryption (with three key management options) and client-side encryption for secure data transfers.

Data Processing:

The S3 Object Lambda lets users add their own code to S3 and obtain S3 GET requests to process and modify data once, it is returned to an application. Your custom code can be used to filter rows, dynamically resize images, redact confidential data, and much more. Powered by AWS Lambda functions, your code runs on infrastructure that is fully managed by AWS, eliminating the need to create and store derivative copies of your data or to run expensive proxies, all with no changes required to applications.

Query in place:

Amazon S3 has efficient features that queries data without having the need to copy and load it into a separate data warehouse or analytics platform, which allows users to run big data analytics directly on your stored resources. S3 Select is an S3 feature designed to increase query performance by up to 400% and reduce querying costs by as much as 80%. It works by retrieving a subset of an object’s data (using simple SQL expressions) instead of the entire object, which can be up to 5 terabytes in size.
