亚马逊网络(S)服务 ( AWS )被誉为(W)世界上最全面、应用最广泛的云平台，已(A)成为(AWS)亚马逊业务组合的重要组成部分。正如(Just)Amazon.com震撼了在线零售领域一样，AWS也(AWS)震撼了计算世界。
Amazon Web Services包含服务器、存储和网络等多种云计算产品和服务，已成为云计算平台的领跑者，盖过了微软 Azure(Microsoft Azure)等竞争对手。
简而言之，AWS是(AWS)亚马逊(Amazon)的摇钱树。但亚马逊网络(Amazon Web) 服务(Services)到底是什么？云计算到底是什么？
什么是亚马逊网络服务？(What Is Amazon Web Services?)
作为Amazon.com(Amazon.com)的子公司，亚马逊网络服务(Amazon Web Services)( AWS ) 提供负担得起的云计算服务，其强大的客户群从Pinterest等小型公司到D-Link等大型企业都有强大的实力。
云(Cloud)计算是使用互联网上的远程服务器来存储、管理和处理数据，而不是使用本地服务器或个人计算机。云(Cloud)计算分为三个基本类别，从软件(Software)即服务(Service)( SaaS ) 开始，它通过提供已包含软件的云服务器来减少公司支出。
平台(Platform)即服务(Service)( PaaS ) 让开发人员无需购买或维护基础设施即可构建应用程序并就各种项目进行协作。
最后，我们有基础设施即服务(Service)( IaaS )，这是AWS比其他服务更受关注的。IaaS为公司提供了从云提供商处租用服务器、存储、安全等的机会。

AWS 的优势(The Benefits of AWS)
成本(Cost)
公司过去必须物理构建存储空间才能存储大量数据并自行维护。除了可能阻碍公司发展的冗长合同之外，选择将数据存储在云上也付出了相当大的代价。购买比需要更多的空间可能会变得过于昂贵，而购买太少可能会带来灾难性的后果。
同样的原理也适用于计算能力。在高峰时期维持业务需要公司购买更多电力。问题在于不再需要电源的非高峰时段。该公司仍然需要为他们甚至没有使用的电力付费。
AWS允许公司只为他们使用的东西付费。由于没有存储和基础架构的前期成本，因此不再需要估算使用量与成本。AWS根据客户的需求自动调整成本。
可扩展性(Scalability)
初创企业和小型企业从(Start-ups)Amazon Web Services提供的可扩展性中获得了明显的好处。成本会根据客户的使用情况进行修改，使AWS成为自下而上构建业务的绝佳选择。该企业将获得使用云启动所需的所有工具。
已经建立的企业将受益于 Amazon 的低成本迁移服务，允许将基础设施无缝迁移到AWS。
由于灵活的使用业务模式，随着业务的持续增长， AWS(AWS)继续提供资源以帮助扩展。客户(Customers)不再需要重新讨论他们当前的计算机使用预算是否必要。在某些与AWS(AWS)的可扩展性有关的情况下，公司可以使用AWS来“设置它并忘记它”。
安全性和可靠性(Security and Reliability)
AWS的服务器位于 76 个可用区内，跨越 245 个国家和地区。这些区域的划分不仅让用户可以选择为其服务设置地理限制，还可以使物理位置多样化，提供更强的安全性并避免全球范围内的永久性数据丢失。
全球的每个数据中心都得到维护和持续监控。可以说，亚马逊网络(Amazon Web) 服务(Services)比托管自己的网站或存储的公司安全得多。这是因为将数据本地化在一个易于识别的位置可能会被证明是脆弱的。
AWS仅在必要时允许访问其物理数据中心。除了保持这些位置对公众隐藏之外，这还为物理入侵创造了更强的屏障。由于亚马逊在云服务方面的经验，停机和潜在的服务器攻击也更加安全。全天候的严格监控使得任何攻击都可以由一名 IT 专家快速识别和处理。
选择亚马逊网络服务(Choosing Amazon Web Services)
Amazon Web Services由在线零售领域的全球领导者构建，消除了识别您的基础设施需求所需的猜测和科学分析。灵活的按使用付费模式为需要更便宜的启动选择的初创公司带来了好处。在 190 多个国家/地区使用AWS的数十万客户中，长期现有业务继续扩展。
AWS的培训和认证也已成为需要创新团队进行云计划的专业人士和组织的追捧和高需求验证。
AWS也不是没有缺点，主要是处理 EC2 的区域到区域的默认资源限制和其他一般的云计算问题，如服务器停机时间和有限的控制。
无论如何，选择Amazon Web Services可以在经济高效、可靠和安全的平台上提供易于使用且没有容量限制的云计算。
HDG Explains : What Is (AWS) Amazon Web Services?
Touted as the world’s moѕt comprehеnsive and broadly adopted cloud platform, Amazon Web Services (AWS) has become a giant component of Amazon’s business portfolio. Just as Amazon.com has shaken up the online retail space, AWS has shaken up the world of computing.
Comprising multiple cloud computing products and services such as servers, storage, and networking, Amazon Web Services has become the frontrunner for cloud computing platforms, overshadowing competitors like Microsoft Azure.
In short, AWS is a cash cow for Amazon. But what is Amazon Web Services exactly? What in the world is cloud computing?
What Is Amazon Web Services?
A subsidiary of Amazon.com, Amazon Web Services (AWS) offers affordable cloud-computing services with the power to make its customer base strong from small scale companies like Pinterest to big enterprises like D-Link.
Cloud computing is the use of remote servers on the internet to store, manage and process data rather than a local server or personal computer. Cloud computing comes in three basic categories beginning with Software as a Service (SaaS) which reduces company expenditure by providing a cloud server with software already included.
Platform as a Service (PaaS) lets developers build apps and collaborate on various projects without the need to purchase or maintain infrastructure.
Last, we have Infrastructure as a Service (IaaS) which is what AWS falls under more so than the others. IaaS provides companies the chance to rent servers, storage, security, etc. from a cloud provider.
Amazon Web Services’ Services
Amazon Web Services provides customers with a wide array of cloud services. Some of the options offered are Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), Amazon Virtual Private Cloud (VPC), Amazon SimpleDB and Amazon WorkSpaces.
- Amazon EC2 provides virtual computing environments offering affordable scalable computing capacity in the AWS cloud. EC2 eliminates the need to invest in hardware, enabling customers to develop and deploy apps at a faster rate.
- Amazon S3 is used in the storage and retrieval of data, at any time, from anywhere in the world on the web. It’s a reliable, scalable, and inexpensive data storage infrastructure that benefits larger businesses.
- Amazon VPC is a virtual data center-like network defined by you which uses the scalable infrastructure of AWS. With Amazon VPC, you can launch your resources kept within the AWS environment into this virtual network without the need to purchase software or infrastructure.
- Amazon SimpleDB is a NoSQL data store for offloading the work of database administration. A developer can store and query different data items via web services request with the reliance that SimpleDB will complete the work.
- Amazon WorkSpaces works as another form of cloud computing, Desktop as a Service (DaaS). With this, you receive a secure desktop solution using either a Windows or Linux operating system. This service can then be scaled to provide virtual desktops to workers all over the world.
The Benefits of AWS
Cost
Companies used to have to physically build a storage space in order to store large amounts of data and maintain it themselves. Choosing to store data on the cloud came at considerable expense on top of lengthy contracts that had the potential to hinder company growth. Purchasing more space than needed could become too expensive, while purchasing too little could prove disastrous.
The same principle applied to computing power. Sustaining business at peak times required that companies buy more power. The problem was during off-peak times when the power was no longer required. The company would still have to pay for power they weren’t even using.
AWS allows companies to only pay for what they use. With no upfront costs on storage and infrastructure, there is no longer a need to estimate usage versus cost. AWS scales cost automatically to the needs of its customers.
Scalability
Start-ups and small businesses receive obvious benefits from the scalability that Amazon Web Services offers. The cost is modified based on the customers’ usage, making AWS a great choice for building a business from the bottom up. That business will receive all the tools necessary to build a start up with the cloud.
Already established businesses will benefit from Amazon’s low-cost migration services allowing a seamless move of infrastructure over to AWS.
AWS continues to provide resources in aid of expansion as a business continues to grow thanks to a flexible usage business model. Customers no longer need to revisit a discussion about whether their current budget for computer usage is necessary. In some circumstances when pertaining to AWS’s scalability, a company can use AWS to “set it and forget it.”
Security and Reliability
AWS has servers located within 76 availability zones, spanning 245 countries and territories. These zones have been divided not only to give users a choice in setting geographical limits on their services, but also to diversify physical locations, providing stronger security and avoiding permanent data loss worldwide.
Every data center across the globe is maintained and continuously monitored. Arguably, Amazon Web Services is much more secure than a company hosting its own website or storage. This is because the localization of data in a single, easily identifiable location could prove vulnerable.
AWS allows access to its physical data centers on an essential basis only. This, on top of keeping these locations hidden from the public, creates a stronger barrier to physical intrusions. Outages and potential server attacks are also safer thanks to Amazon’s experience with cloud services. The round the clock heavy monitoring makes it so that any attack can be quickly identified and dealt with by a single IT specialist.
Choosing Amazon Web Services
Built by a global leader in online retail, Amazon Web Services removes the guess-work and scientific analysis required to identify your infrastructure needs. The flexible pay-per-use model reaps benefits for startups in need of a cheaper starting option. While longtime existing businesses continue to expand with hundreds and thousands of customers leveraging AWS in over 190 countries.
The training and certification of AWS has also become a much sought after and high in-demand validation by professionals and organizations in need of innovative teams for cloud initiatives.
AWS is not without its disadvantages, primarily dealing with EC2’s region to region default resource limits and other general cloud computing issues like server downtime and limited control.
Regardless, choosing Amazon Web Services provides easy-to-use cloud computing with no capacity limits on a cost-effective, reliable and secure platform.
