Storage

Amazon S3

Amazon Simple Storage Service (Amazon S3) is object storage with a simple web service interface to store and retrieve any amount of data from anywhere on the web. It is designed to deliver 99.999999999% durability, and scales past trillions of objects worldwide.

You can use Amazon S3 as primary storage for cloud-native applications; as a bulk repository, or "data lake," for analytics; as a target for backup and recovery and disaster recovery; and with serverless computing.

It's simple to move large volumes of data into or out of Amazon S3 with Amazon's cloud data migration options. Once data is stored in Amazon S3, it can be automatically tiered into lower cost, longer-term cloud storage classes like Amazon S3 Standard - Infrequent Access and Amazon Glacier for archiving.

Amazon S3 Features

Amazon S3 provides the most feature-rich object storage platform available in the cloud today.

  • Simple: Amazon S3 is simple to use with a web-based management console and mobile app. Amazon S3 also provides full REST APIs and SDKs for easy integration with third-party technologies.

  • Durable: Amazon S3 provides durable infrastructure to store important data and is designed for durability of 99.999999999% of objects. Your data is redundantly stored across multiple facilities and multiple devices in each facility.

  • Scalable: With Amazon S3, you can store as much data as you want and access it when needed. You can stop guessing your future storage needs and scale up and down as required, dramatically increasing business agility.

  • Secure: Amazon S3 supports data transfer over SSL and automatic encryption of your data once it is uploaded. You can also configure bucket policies to manage object permissions and control access to your data using  IAM.

  • Available: Amazon S3 Standard is designed for up to 99.99% availability of objects over a given year and is backed by the Amazon S3 Service Level Agreement, ensuring that you can rely on it when needed. You can also choose an AWS Region to optimize for latency, minimize costs, or address regulatory requirements.

  • Low Cost: Amazon S3 allows you to store large amounts of data at a very low cost. Using lifecycle policies, you can set policies to automatically migrate your data to Standard - Infrequent Access and Amazon Glacier as it ages to further reduce costs.

  • Simple Data Transfer: Amazon provides multiple options for cloud data migration, and makes it simple and cost-effective for you to move large volumes of data into or out of Amazon S3. You can choose from network-optimized, physical disk-based, or third-party connector methods for import to or export from Amazon S3. 

  • Integrated: Amazon S3 is deeply integrated with other AWS services to make it easier to build solutions that use a range of AWS services. Integrations include Amazon CloudFrontAmazon CloudWatchAmazon KinesisAmazon RDSAmazon GlacierAmazon EBSAmazon DynamoDBAmazon RedshiftAmazon Route 53Amazon EMRAmazon VPCAmazon Key Management Service (KMS), and AWS Lambda.

  • Easy to Manage: Amazon S3 Storage Management features allow you to take a data-driven approach to storage optimization, data security, and management efficiency. These enterprise-class capabilities give you data about your data, so you can manage your storage based on that personalized metadata.

Amazon Elastic Block Store

Amazon Elastic Block Store (Amazon EBS) provides persistent block storage volumes for use with Amazon EC2 instances in the AWS Cloud. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. Amazon EBS volumes offer the consistent and low-latency performance needed to run your workloads. With Amazon EBS, you can scale your usage up or down within minutes—all while paying a low price for only what you provision.

Amazon EBS Features

  • High Performance Volumes: Choose between solid-state disk (SSD)-backed or hard disk drive (HDD)-backed volumes that can deliver the performance you need for your most demanding applications.

  • Availability: Each Amazon EBS volume is designed for 99.999% availability and automatically replicates within its Availability Zone to protect your applications from component failure.

  • Encryption: Amazon EBS encryption provides seamless support for data-at-rest and data-in-transit between EC2 instances and EBS volumes.

  • Access Management: Amazon’s flexible access control policies allow you to specify who can access which EBS volumes ensuring secure access to your data.

  • Snapshots: Protect your data by creating point-in-time snapshots of EBS volumes, which are backed up to Amazon S3 for long-term durability.

Amazon Elastic File System

Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the AWS Cloud. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.

When mounted on Amazon EC2 instances, an Amazon EFS file system provides a standard file system interface and file system access semantics, allowing you to seamlessly integrate Amazon EFS with your existing applications and tools. Multiple EC2 instances can access an Amazon EFS file system at the same time, allowing Amazon EFS to provide a common data source for workloads and applications running on more than one EC2 instance.

You can mount your Amazon EFS file systems on your on-premises data center servers when connected to your VPC with AWS Direct Connect. You can mount your Amazon EFS file systems on on-premises servers to migrate data sets to EFS, enable cloud bursting scenarios, or backup your on-premises data to EFS.

Amazon EFS is designed for high availability and durability, and provides performance for a broad spectrum of workloads and applications, including big data and analytics, media processing workflows, content management, web serving, and home directories.

Amazon Glacier

Amazon Glacier is a secure, durable, and extremely low-cost storage service for data archiving and long-term backup. You can reliably store large or small amounts of data for as little as $0.004 per gigabyte per month, a significant savings compared to on-premises solutions. To keep costs low yet suitable for varying retrieval needs, Amazon Glacier provides three options for access to archives, from a few minutes to several hours.

AWS Storage Gateway

The AWS Storage Gateway service seamlessly enables hybrid storage between on-premises storage environments and the AWS Cloud. It combines a multi-protocol storage appliance with highly efficient network connectivity to Amazon cloud storage services, delivering local performance with virtually unlimited scale. You can use it in remote offices and data centers for hybrid cloud workloads involving migration, bursting, and storage tiering.
