Route 53 is a highly available and scalable Domain Name System (DNS) web service.
Route 53 is a service that helps connect your website or application to the internet by managing domain names and translating them into IP addresses that computers understand. Unlike traditional DNS management services, Route 53, together with other AWS services, enables scalable, flexible, secure and manageable traffic routing.
Domain registration:Lets you register domain names.
Domain Name System (DNS) service:Translates domain names into IP addresses and routes internet traffic to your resources like CloudFront, Elastic Beanstalk, ELB, or S3. It also covers non-AWS resources or services like Azure, GCP (Google Cloud Platform) and others.There’s no charge for DNS queries to these resources.
Supported DNS Resource Record Types:
A Format is an IPv4 address in dotted decimal notation for e.g. 192.0.2.1.
AAAA format refers to a type of DNS record used for IPv6 addresses. The AAAA record maps a domain name to an IPv6 address, allowing clients to resolve the domain name to the corresponding IPv6 address.
CNAME Format is the same format as a domain name.DNS protocol does not allow creation of a CNAME record for the top node of a DNS namespace.
MX Format contains a decimal number that represents the priority of the MX record and the domain name of an email server
An NS record identifies the name servers for the hosted zone. The value for an NS record is the domain name of a name server.
A PTR record Value element is the same format as a domain name.
SOA record provides information about a domain and the corresponding Amazon Route 53 hosted zone.
SPF records were formerly used to verify the identity of the sender of email messages, however is not recommended.
A TXT record contains a space-separated list of double-quoted strings.A single string include a maximum of 255 characters.
Health Checking:To ensure the availability and functionality of resources such as web and email servers, automated health checks are performed using CloudWatch. These checks involve sending requests over the Internet to verify that the application is reachable and operational. CloudWatch alarms can be set up to notify users when a resource becomes unavailable, allowing for quick response and resolution. Additionally, traffic routing can be configured to redirect Internet traffic away from unavailable resources, ensuring uninterrupted service for users.
Hosted zones:In AWS Route 53, a hosted zone is a container that holds information about how you want to route traffic for a domain, including information about the domain's DNS records. It essentially serves as a zone file for your domain.
When you register a domain name and want to use Route 53 as the DNS service for that domain, you create a hosted zone for the domain in Route 53. This hosted zone contains records that specify how you want to route traffic for the domain, such as mapping the domain to an Elastic Load Balancer (ELB) or an EC2 instance's IP address.
Hosted zones in Route 53 allow you to manage DNS settings for your domain, such as creating and updating DNS records, setting up routing policies and configuring health checks for your resources.
Go to the Route 53 service. In the Route 53 console, look for "Hosted zones" in the menu on the left side of the screen. Click on the "Create hosted zone" button to begin setting up a new hosted zone.
Enter your domain name and you can also Provide description of the domain, which could include the purpose of the website or application. Then, select the type of zone you want to create, which can be either "private" or "public". A public zone is used for websites or applications that are accessible over the internet, while a private zone is used for internal websites or applications that are not intended to be accessed publicly.Select the type of zone as "private" since we are creating a private hosted zone.
Choose the Virtual Private Clouds (VPCs) that you want to associate with the hosted zone. Select the region where the VPCs are located. Then, click on "Create hosted zone" to complete the process. This will create the hosted zone and associate it with the selected VPCs in the specified region.
The hosted zone has been successfully created.
Route 53 provides the user with several benefits.
Highly Available and Reliable-DNS servers are distributed across many availability zones, which helps in routing end users to your website consistently.
Flexible-Route 53 Traffic Flow provides users flexibility in choosing traffic policies based on multiple criteria
Simple-Your DNS queries are promptly handled by Route 53 in AWS shortly after setup and the sign-up process is self-service.
Cost-effective-You only pay for what you use
Secure-You can create and grant unique credentials and permissions to each and every user with your AWS account
In conclusion, AWS Route 53 is a reliable and scalable service that helps connect your website or application to the internet by managing domain names and routing traffic to your resources. It offers benefits such as high availability, flexibility, simplicity, cost-effectiveness and security.
Cloud migration is the process of moving digital assets like data, applications and IT resources to the cloud. It offers benefits such as cost efficiency and scalability, allowing businesses to adjust their IT resources based on fluctuating workloads.
Overall, both AWS Route 53 and cloud migration offer significant advantages for businesses looking to improve their infrastructure and operations.
