Amazon Route 53 is a highly available and scalable cloud Domain Name System web service, giving developers and businesses a reliable and cost effective way to route users to Internet applications by translating names (e.g. www.example.com)into numeric IP addresses(e.g. 192.0.2.1 that computers use to connect to each
other. Features

It will help if you say what assistive technology you use. The Domain Name System (DNS) is a global infrastructure that translates human-readable hostnames into IP addresses. Organizations using Amazon Web Services (AWS) are running machines in the cloud, and need a mechanism to translate user requests into the correct Amazon IP address. On the cloud, IP addresses can frequently change, as services move between physical machines and data centers. An AWS DNS solution must be able to
adapt to these changes and propagate them quickly to DNS clients. Amazon’s official DNS solution is called Route 53. Route 53 is a managed DNS service from Amazon Web Services, intended for managing DNS for machines and services deployed on Amazon’s
public cloud. Route 53 connects user requests to infrastructure running on AWS, such as Amazon EC2 instances, ELB load balancers or Amazon S3 buckets. Route 53 Key Features
Route 53 PricingAWS charges several monthly rates depending on your usage:
SecurityIn April 2018, Russian hackers conducted a BGP attack against the Amazon Route 53 service, and hijacked 1,300 IP addresses owned by AWS and using Route 53 for DNS. The victim was a cryptocurrency website—hackers managed to redirect users to a spoofed duplicate site, and steal $160,000 in cryptocurrency. Industry experts said that deploying DNSSEC (secure DNS) and HSTS (Google’s new, secure transport protocol) would have prevented users from being sent to a fake site.could have prevented the attack. At the time of this writing, Route 53 does not support either of these services, making it potentially vulnerable to attack. How Amazon’s DNS Service WorksImage Source When a user accesses a web server using Route 53 DNS, the following process occurs:
Amazon Route 53 LimitationsAmazon Route 53 is a robust DNS service with advanced features, but it has several important limitations:
You can implement several workarounds for forwarding Route 53 DNS queries to external servers—but this will still incur latency, because the requests must contact Amazon infrastructure first, and are only then forwarded to the external server. In addition, at the time of this writing, Amazon Route 53 does not support the DNSSEC standard, which digitally signs DNS records to ensure they are identical to the information published by the DNS name server. DNSSEC can prevent several types of DNS attacks, including man in the middle (MITM) attacks. AWS DNS AlternativesWhile Route 53 is a natural option for managing DNS in Amazon’s ecosystem, it is possible to use third-party DNS providers. However, you need to make sure that your DNS provider is able to intelligently route traffic to the optimal endpoint, data center or geography in the same way that Route 53 does. NS1 is a next-generation managed DNS service with advanced traffic routing capabilities. It uses a fast global network of DNS servers, and provides advanced capabilities such as anycast networking, point-and-click traffic management and data-driven content delivery. NS1 provides a REST API and built-in integration with deployment and automation tools, allowing you to provide up-to-date information about your AWS servers, their physical location, data center, load, availability, and more. NS1 can then route traffic according to these parameters, provided in real time. This means NS1 can provide similar features to Route 53—latency-based routing, geographic routing, health checks and DNS failover—and much more, because it allows you to route traffic based on any server attribute or traffic condition. Contact us for a demo to see how NS1 can help you manage traffic on AWS without the limitations of Route 53. What is the name of DNS service in AWS?Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. Route 53 connects user requests to internet applications running on AWS or on-premises.
What domain name service DNS is used for?DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser.
Which AWS service is used for DNS name resolution?The Amazon DNS server in your VPC is used to resolve the DNS domain names that you specify in a private hosted zone in Route 53. For more information about private hosted zones, see Working with private hosted zones in the Amazon Route 53 Developer Guide.
Which AWS service can act as a Domain Name System DNS and provide human translation of the numeric IP addresses?With Amazon Route 53, you can create and manage your public DNS records. Like a phone book, Route 53 lets you manage the IP addresses listed for your domain names in the Internet's DNS phone book. Route 53 also answers requests to translate specific domain names like into their corresponding IP addresses like 192.0.
