In
Simplest terms, cloud computing means storing and accessing the data and
programs on remote servers hosted on the internet instead of the computer’s
hard drive or local server. It is also referred to as Internet-based computing.
In this article we guide on discussing what is Amazon Route53, how does it
works, benefits, limitations many more, the following Table of Content gives
clear understanding on that we going to discuss in this article.
What Is
Amazon Route 53?
Amazon Route 53 is a highly available and scalable cloud DNS web service. It is designed for developers and corporations to route the end users to Internet applications by translating human-readable names like www.geeksforgeeks.org into the numeric IP address like 192.0.1.1 that computers use to connect. You cannot use Amazon Route 53 to connect your on-premises network with AWS Cloud.
How Does
Amazon Route53 Works?
Amazon
Route53 is an aws service than offers a DNS (Domain Name System) web service
which is scalable and high available. It is essential for conversion of user
friendly domain names into IP addresses so that internet communication can
proceed without difficulties. The following are the some of the main features
explaining on how Amazon Route 53 functions well:
- Domain Registration And
Management: Amazon Route 53 allows users to register and maintain domain names
through its user-friendly interface. Users can transfer their existing
domain to the Route 53 service or can go for register a new one. Users may
freely configure the DNS settings, including mail server setups (MX
records), domain name aliases , and more, once they have registered.
- Global DNS Resolution: Route 53 uses a worldwidet
network cast made up of many DNS servers that have been placed
strategically all over the world. The IP address which matches to a domain
name entered by a user in their web browser is sent back by Route 53’s DNS
servers. Users can immediately access the websites and services from
anywhere in the globe because of Route 53’s low latency and
high-performance DNS resolution by using global network.
- Traffic Routing And Load
Balancing: Users can set up load balancing and fallback
setups for their applications with Route 53’s wide traffic routing
capabilities. Users may distribute incoming traffic among several
endpoints, such as EC2 instances, ELB, or by other external resources,
by utilizing capabilities like DNS-based latency routing and weighted
round-robin routing.
Functions
Of Route53
- If a web application requires a
domain name, Route53 service helps to register the name for the website
(i.e domain name).
- Whenever a user enters the
domain name, Route53 helps to connect the user to the website.
- If any failure is detected at
any level, it automatically routes the user to a healthy resource.
- Amazon Route 53 is cost
effective, secure and scalable.
- Amazon Route 53 is flexible,
highly available and reliable.
Methodologies
Related To Route53
- Records: Records are
created to route internet traffic to the resources. They are the objects
present in the hosted zone which determines how the internet traffic has
to be routed for a domain name so that it finally reaches the resources.
The name of each record in a hosted zone must end with the name of the
hosted zone.
- Hosted zone: When the
domain name is registered, Route53 creates a public hosted zone that has
the same name as the domain name. It is a collection of records that
contains information about how to route traffic of its domains and all of
its subdomains.
- DNS query: It is a request
for information sent from DNS client to the DNS server.
- Alias records: Alias
records helps in routing internet traffic to AWS resources like S3 bucket,
Amazon CloudFront, etc. It is created at the top node of the DNS
namespace.
- Name servers: They are the
servers in the DNS that translates the domain name into IP address so that
internet traffic can be routed to the resources.
- DNS failover: A method for
routing the traffic from unhealthy resources to healthy resources,
whenever a failure is detected.
- Routing policy: Routing
policy determines how Amazon Route53 responds to queries.
Types Of
AWS Routing Policies
The
following are the types of AWS Routing Policies:
- Simple Routing Policy: It
is a simple Route53 routing technique that can be used to route internet
traffic to a single resource. For example; Web server to a website. Using
this, routing multiple records with the same name cannot be created but
multiple values ( such as multiple IP addresses ) can be specified in the
same record.
- Failover Routing Policy: Whenever
a resource goes unhealthy, this policy allows to route the traffic from
unhealthy resource to healthy resource.
- Geolocation Routing
Policy: This routing policy routes the traffic to resources on the
basis of the geographic location of the user. Geographic locations can be
specified by continent, country, or state. For example; A person
residing in France will be redirected to the website in the French
language while a person from the US will be redirected to the website in
the English language.
- Geoproximity Routing Policy: It
routes traffic on the basis of the geographical location of the user and
the type of content user wants to access. The user can optionally shift
traffic from resources at one location to resource at another location.
Using this policy, a user can shift more traffic to one location compared
to another location by specifying a value known as bias.
- Latency Routing Policy: If
a website has to be hosted in multiple regions then a latency based
routing policy is used. To improve performance for the users, this policy
helps in serving requests from the AWS region that provides the lowest
latency. To use this policy, the latency records for the resources
are created in multiple AWS regions.
- Multivalue Routing Policy: It
is used when users want Route53 to return multiple values in response to
DNS queries. It first checks the health of resources and then returns the
multiple values only for the health resources.
- Weighted Routing Policy: This
routing policy routes traffic to multiple resources with a single domain
name according to the proportion decided by the user.
Amazon
Route53 supported DNS Record Types
The
following are the DNS record types that are supported in Amazon Route53:
- A Record ( Address Record ): It
is associated with an IPv4 address that is used to point a
domain or subdomain to specify a IP address.
- AAAA Record ( IPv6 Address
Record ): It is similar to A Record type but it is associated with
IPv6 address. It associates the name with an IPv6 Address.
- CNAME Record ( Canonical Name
Record ): It creates an alias to Domain Name that pointing to another
domain name. It used for setuping subdomains or pointing multiple domain
names to the same server.
- MX Record (Mail Exchange Record
): It specifies the mail server responses to receiving email on
behalf of a domain. It is used for email routing.
