您是否有大量数据需要存储？您(Are)是否厌倦了支付大量的固定费用来存储这些数据？对安全、加密文件上传和下载的需求如何？如果其中任何一个问题之后都是响亮的“是(Yes)”，那么Amazon S3可能是一个值得探索的选项。
但是什么是Amazon S3？凭借其简单的 Web 服务界面，Amazon S3为所有这些问题以及您的数据存储需求提供了更多解决方案。开发人员可以访问与亚马逊(Amazon)运行其自己的全球网站网络相同的高度可扩展、可靠、快速、廉价的数据存储基础设施。
使用Amazon S3，您将能够随时随地从网络上的任何位置存储和检索任意数量的数据。
什么是亚马逊 S3？(What Is Amazon S3?)
Amazon Simple S存储服务 ( S3(S) ) 的设计考虑了开发人员。(S)它使 Web 规模的计算更容易，并且是稳固的(S)A mazon Web服务 ( AWS(W) ) 云环境的重要组成部分。
通过 Web 界面，Amazon S3提供对象(object )存储，或者如AWS所说，“可以存储在 Amazon S3 中的基本实体”。对象存储旨在存储、保护和检索“基本存储容器”（称为存储桶(buckets)）中的数据。用户创建一个bucket，bucket将对象存储在云端。
该服务适用于任何行业的任何规模的组织，用于但不限于网站、移动应用程序、存档、数据备份和恢复、物联网(IoT)设备和企业应用程序。
Amazon S3 如何工作？(How Does Amazon S3 Work?)
要了解Amazon S3是什么以及它是如何工作的，我们将更深入地研究存储系统的每个组件。我们将关注两个主要的东西——桶和对象。这两个组件协同工作以创建您的Amazon S3存储系统。
Amazon S3对象可以是任何文件类型的文档、照片、视频等。每个对象都被赋予一个唯一的密钥，使其在 S3 环境中可识别。对象(Object)文件上传大小设置为最大 160 GB，但AWS拥有各种工具来帮助您在必要时添加更大的文件。
对象需要在 S3 环境中存储位置，这就是存储桶发挥作用的地方。如前所述，存储桶是对象的基本存储容器。您可以使用Amazon S3 API(Amazon S3 API)将无限对象上传到单个存储桶。
AWS将您的每个(AWS)AWS云账户的存储桶创建限制为 100 个。提交服务限制增加请求后，此数量最多可增加到 1000。
创建存储桶后，您将选择要存储它的AWS区域。(AWS)该区域离您的物理位置越近，您的延迟问题和成本就越低。存储在特定区域中的存储桶中的对象将保留在那里，直到您转移为止。
每个存储桶的唯一标识符是全局的。这意味着在删除该存储桶之前，世界上没有其他地方的存储桶与您创建的存储桶具有相同的名称。
Amazon S3 控制台(Amazon S3 Console)可以在AWS管理控制台(AWS Management Console)中找到。您将在这里创建、配置和管理每个存储桶以及其中保存的存储对象。
Amazon S3控制台使用分层文件夹结构，允许搜索包含关键字或短语，帮助您轻松找到和检索您正在寻找的内容。
还使用管理控制台设置对存储桶和对象的访问权限。
Amazon S3 的优势(The Advantages Of Amazon S3)
Amazon S3是简单而强大的安全存储。所提供的功能提供了可扩展性、耐用性、可访问性、成本效益和安全性。它们还提供称为版本控制的功能，它允许您在同一存储桶中创建对象的副本，作为数据回滚或恢复的故障保护。
可扩展性(Scalability)
Amazon S3的标准与您的普通云存储提供商不同。Amazon S3无需为您可能使用或不使用的设定限制付费，而是仅按您实际使用的内容向您收费。
这项服务有助于避免因空置空间而被多收费用，以及在您超出限额时可能产生的超额费用。Amazon S3完全没有隐藏费用或超额费用。您可以上下扩展存储资源以满足您不断变化的需求。
耐用性、可访问性和成本效益(Durability, Accessibility, And Cost-effectiveness)
AWS指出，Amazon S3 “旨在实现 99.999999999% 的持久性，并为全球公司的数百万个应用程序存储数据。” Amazon S3跨多个受故障保护的系统自动创建和存储您的 S3 对象。这允许在需要时快速访问您的数据。
数据可以存储在一系列基于频率的存储类别(storage classes)中。存储类别的成本从高到低不等，具体取决于文件对任务的关键程度以及某些文件的访问频率。
如果您需要立即访问重要文件，则范围将设置为更昂贵的一端。这可能会随着时间的推移而改变，具体取决于访问文件的频率。AWS为您提供了监控每个对象并确定是否需要将它们移动到更高或更低存储类的工具。它还将根据正在进行的访问模式自动移动您的对象。
此设置对于创建生命周期策略很有用，该策略定义了您希望Amazon S3在对象生命周期内采取的操作。这方面的一个例子是将对象转换到另一个存储类、它们的存档或在一段时间后删除。然后，只要满足您设置的政策条款，您就可以设置自动数据传输。
安全(Security)
加密功能和访问工具可保护您存储在AWS S3环境中的数据免遭未经授权的访问。这适用于存储桶级别和帐户级别。
默认情况下，用户只能访问他们创建的存储桶和对象。AWS提供各种安全管理功能供您使用，以更改和自定义访问权限。
选择亚马逊 S3(Choosing Amazon S3)
Amazon S3是为需要可扩展性的成熟企业构建的，因此可能不适合需要最少数据存储且没有近期扩展计划的小型企业。
然而，凭借灵活的成本模型、强大的架构和在 Web 上无处不在的存在，Amazon S3是任何需要可根据需要扩展的 Web 可访问数据的企业的理想选择。
HDG Explains : What Is Amazon S3?
Do уou have large amounts of data that need to be stored? Are you tired of paying large, flat-rate fees to store that data? Hоw about the need for secure, encrypted file υploads and downloads? If any of these questions was followed by a resounding “Yes,” then Amazon S3 may be аn option worth exploring.
But what is Amazon S3? With its simple web services interface, Amazon S3 provides solutions to all of these questions and much more in terms of your data storage needs. Developers can enjoy access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon runs its own global network of websites on.
Using Amazon S3, you’ll be able to store and retrieve any amount of data, at any time, from anywhere on the web.
What Is Amazon S3?
Amazon Simple Storage Service (S3) was designed with developers in mind. It makes web-scale computing easier and is an important part of a solid Amazon Web Services (AWS) cloud environment.
Through the web interface, Amazon S3 provides object storage, or as AWS calls it, “fundamental entities that can be stored in Amazon S3.” Object storage was built to store, protect, and retrieve data from “fundamental storage containers” referred to as buckets. A user creates a bucket, and the bucket stores objects in the cloud.
This service is available to organizations of any size in any industry for the use of, but not limited to, websites, mobile apps, archiving, data backups and restorations, IoT devices, and enterprise apps.
How Does Amazon S3 Work?
To understand what Amazon S3 is and how it all works, we’ll dive a bit deeper into each component of the storage system. We’ll focus on two main things — buckets and objects. These two components work in tandem to create your Amazon S3 storage system.
Amazon S3 objects could be documents, photos, videos and more of any file type. Each object is given a unique key that makes it identifiable within the S3 environment. Object file upload size is set to a maximum of 160 GB, though AWS possesses various tools to assist you with adding larger files if necessary.
Objects are in need of places to be stored within the S3 environment, and this is where buckets come into play. As previously mentioned, a bucket is the fundamental storage container for an object. You can upload unlimited objects to a single bucket using the Amazon S3 API.
AWS limits the creation of buckets to 100 for each of your AWS cloud accounts. This number can be increased to a maximum of 1000 upon submission of a service limit increase request.
When a bucket is created, you’ll choose the AWS region for where you’ll want it stored. The closer the region is to your physical location, the minimal your latency concerns and costs will be. Objects within a bucket stored in a specific region will remain there until transferred by you.
The unique identifier for each bucket is global. This means that nowhere else in the world will a bucket have the same name as the one you’ve created until that bucket has been deleted.
The Amazon S3 Console can be found within the AWS Management Console. It’s where you’ll create, configure, and manage every bucket as well as the storage objects held within.
The Amazon S3 console uses a hierarchical folder structure that allows for searches containing either keywords or phrases that help you easily find and retrieve what you’re looking for.
Access permissions to your buckets and objects are also set using the management console.
The Advantages Of Amazon S3
Amazon S3 is simple and robust secure storage. The features provided offer scalability, durability, accessibility, cost-effectiveness, and security. They also offer something referred to as versioning, which allows you to create duplicates of an object within the same bucket as a failsafe for a data rollback or recovery.
Scalability
Amazon S3 is not held to the same standard as your run-of-the-mill cloud storage provider. Instead of paying for set limits that you may or may not use, Amazon S3 only charges you for what you actually use.
This service helps to avoid being overcharged for unoccupied space and the potential for overage fees should you go over your limit. There are no hidden fees or overage charges at all with Amazon S3. You can scale your storage resources up and down to meet your fluctuating demands.
Durability, Accessibility, And Cost-effectiveness
AWS notes that Amazon S3 is “designed for 99.999999999% of durability and stores data for millions of applications for companies all around the world.” Amazon S3 automatically creates and stores your S3 objects across multiple failure-protected systems. This allows for quick access to your data when needed.
The data can be stored in a range of frequency-based storage classes. Storage classes range from high to low cost, based around how mission-critical the files are to how frequently certain files are accessed.
If you need immediate access to important files, the range will be set to the more expensive end. This could change over time depending on how often the files are accessed. AWS gives you the tools to monitor each object and determine if they need to be moved to a higher or lower storage class. It will also move your objects automatically based on ongoing access patterns.
This setup is useful for creating a lifecycle policy, which is what defines the actions you want Amazon S3 to take during an object’s lifetime. An example of this would be the transition of objects to another storage class, their archival, or deletion after a certain period of time. You can then set up automatic data transference whenever the policy terms you’ve set are met.
Security
Encryption features and access tools protect the data you store within your AWS S3 environment from unauthorized access. This is for both the bucket level and at the account level.
By default, users will only have access to the buckets and objects they create. AWS offers a variety of security management features at your disposal to change and customize access permissions.
Choosing Amazon S3
Amazon S3 was built for mature businesses that need scalability and therefore may not be ideal for smaller businesses in need of minimal data storage, and no near-term future plans for expanding.
However, with a flexible cost model, robust architecture, and a ubiquitous presence on the web, Amazon S3 is a good choice for any business requiring web-accessible data that scales to its needs.
