Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost effective way to route end users to Internet applications by translating human readable names like www.example.com into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other. Route 53 effectively connects user requests to infrastructure running in Amazon Web Services (AWS) – such as an Amazon Elastic Compute Cloud (Amazon EC2) instance, an Amazon Elastic Load Balancer, or an Amazon Simple Storage Service (Amazon S3) bucket – and can also be used to route users to infrastructure outside of AWS. 

 

Amazon Route 53是一个高可用、可扩展的域名系统(DNS)的网络服务。它提供给开发者和公司一个非常可靠并且划算的方法使终端用户能够通过把人类可识别的名称(例如:www.example.com) 转换为ip地址(例如192.0.2.1,ip地址是计算机之间互相连接的标识)能够使用到网络应用.Route 53 有效地把用户请求连接到基础设施-例如亚马逊弹性计算云(Amazon EC2)实例，亚马逊弹性负载均衡，或者亚马逊简单存储服务(Amazon S3)的集群-并且也用于引导用户访问aws之外的基础设施。


 
Much like a phone book, the Internet’s DNS system manages mapping between names and numbers. In DNS’s case, the names are domain names (www.example.com) that are easy for your users to remember. Instead of phone numbers, in DNS, these names are mapped to IP addresses (192.0.2.1) that specify the location of computers on the Internet. Route 53 performs two DNS functions. First, it lets you manage the IP addresses listed for your domain names in the Internet’s DNS phone book. These listings are called DNS “records.” Second, like a directory assistance service, Route 53 answers requests to translate specific domain names into their corresponding IP addresses. These requests are called “queries.” 

 
类似于电话本，互联网的DNS系统管理域名和ip的对应关系。在dns记录里,名字就是很容易记住的域名(例如www.example.com)。类似于电话号码，在DNS系统里，名字对应的是表示因特网里计算机的位置的ip地址(例如192.0.2.1)。Route 53平台有两个DNS功能。第一，它能使在DNS系统里你管理你的域名下的ip地址列表。这些列表项称为DNS记录。第二，像字典一样可以查询，Route 53 会针对查询某些域名应答出这些域名的正确ip地址。这些请求称为dns查询。

 
Route 53 is designed to be fast, easy to use, and cost-effective. It answers DNS queries with low latency by using a global network of DNS servers. Queries for your domain are automatically routed to the nearest DNS server, and thus answered with the best possible performance. With Route 53, you can create and manage your public DNS records with an easy-to-use API. It’s also integrated with other Amazon Web Services. For instance, by using the AWS Identity and Access Management (IAM) service with Route 53, you can control who in your organization can make changes to your DNS records. Like other Amazon Web Services, there are no long-term contracts or minimum usage requirements for using Route 53 – you pay only for managing domains through the service and the number of queries that the service answers.

 
Route 53 是快速，易用，划算。它通过一个全球的DNS服务器网络实现低时延地应答DNS请求。对于你的域名的查询的会被引到最近的DNS服务器上，并且这样应答能够达到最好的效果。在 Route 53平台里，你可以通过易用的API创建和管理你的DNS记录。他也和其它的亚马逊网络服务联成一体。例如在Route 53里通过使用aws的认证访问管理服务，你可以控制你的公司里谁能够修改你的DNS记录。像其它的亚马逊网络服务，对于使用Route 53没有长期的联系或者最小限度的需求-你花的钱用于通过服务管理域名和服务应答次数。

 
Highly Available – Route 53 is built using AWS’s highly available and reliable infrastructure. The distributed nature of our DNS servers helps ensure a consistent ability to route your end users to your application. Route 53 is designed to provide the level of dependability required by important applications.
高有效-Route 53是使用AWS的高有效和可用的基础设施。我们的dns服务器分布特性有利于确保有能力让你的终端用户访问到你的应用。Route 53能够提供重要应用等级的需求。

 
Scalable – Route 53 is designed to automatically scale to handle very large query volumes without any intervention from you.
可扩展性- Route 53设计为不需要你的介入，能够自动扩展处理大量请求。

 
Designed for use with other Amazon Web Services – Route 53 is designed to work well with other AWS features and offerings. You can use Route 53 to map domain names to your Amazon EC2 instances, Amazon S3 buckets, Amazon CloudFront distributions, and other AWS resources. By using the AWS Identity and Access Management (IAM) service with Route 53, you get fine grained control over who can update your DNS data. You can use Route 53 to map your zone apex (mydomain.com versus www.mydomain.com)to your Elastic Load Balancing instance using a feature called Alias records. In the future, we plan to add additional integration features such as the ability to route your customers to the closest EC2 region.
设计用于其它的亚马逊网络服务-Route 53 能够很好地和其它的AWS产品协同工作。你可以用 Route 53把域名对应你的Amazon EC2实例，Amazon S3 集群，Amazon CloudFront 分布，和其它的AWS资源。在Route 53里通过使用aws的认证访问管理服务，你可以很好地控制谁能更新你的DNS记录。你可以使用Route 53 把你的一级域名(mydomain.com 对应 www.mydomain.com)映射到你的弹性负载均衡实例，这种方法叫做别名记录。将来，我们计划添加完备的特性，例如使你的客户访问到最近的EC2区域。

Simple – With self-service sign-up and a few simple API calls to configure your DNS settings, Route 53 can start to answer your DNS queries within minutes. You can also programmatically integrate the Route 53 API into your overall web application. For instance, you can use Route 53’s API to create a new DNS record whenever you create a new EC2 instance.
简单-通过自服务登录和一些简单API调用可以配置你的DNS设置，Route 53能够在几分钟内开始响应你的DNS请求。你也可以用程序的方式把 Route 53 的API整合到你的网络应用里。例如每次你创建一个EC2实例是，可以使用 Route 53 的API去创建一个新的DNS记录。
Fast – Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically route your users to the optimal location depending on network conditions. As a result, the service offers low query latency for your end users, as well as low update latency for your DNS record management needs.
快速-使用全球的一个全球泛播DNS服务器网络，Route 53 根据网络环境能够自动引导你的用户到一个优化的位置。最终提供一个时延短的服务给你的终端用户，并且同时提高你的dns记录更新时延。
Cost-Effective – Route 53 passes on the benefits of AWS’s scale to you. You pay only for managing domains through the service and the number of queries that the service answers for each of your domains, at a low cost and without minimum usage commitments or any up-front fees.
划算-Route 53 把一个可以达到盈利的aws给你。你只需要为管理域名服务和应答你的所有域名请求的次数付费，付费低而且没有义务和任何预付费。
