DOMAIN NAME SYSTEM (DNS)

Oracle Cloud Infrastructure (OCI) DNS is a cloud native DNS service that serves
both internet-facing and internal requests. It can globally load balance and
steer requests based on multiple characteristics.

USE CASES FOR OCI DNS

View more DNS scenarios

This image shows four common use cases for OCI Domain Name System, commonly
abbreviated as DNS. These use cases are:

 1. Public DNS
 2. Private DNS
 3. Traffic load balancing
 4. Traffic steering

Public DNS
In this first use cases, an OCI region contains a virtual cloud network that is
serviced by the DNS service. The internet is logically and bidirectionally
connected to the DNS service.

Requests from the internet can access the DNS service and the DNS service
responds to requests from the internet.

Private DNS
In the second use case, an OCI region contains a virtual cloud network that is
serviced by the DNS service. A dynamic routing gateway is attached to the
virtual cloud network. The dynamic routing gateway is logically and
bidirectionally connected to an on-premises environment.

Requests from the on-premises environment can access the DNS service and the DNS
service responds to requests from the on-premises environment.

Traffic load balancing
In the third use case, a computer application is logically connected to two
different virtual machines, which represent endpoints that the application can
connect to. Traffic load balancing is a capability of the DNS service that
directs applications to different endpoints based on equal or custom weights.

Traffic steering
In the fourth use case, two users are located in different geographies. The
first user is connected to an OCI region. The second user is connected to
different OCI region.

Through DNS, users in different geographies can be directed through DNS to
different OCI regions based on the user’s location, the nature of the DNS
request, or the source network address.


BENEFITS OF OCI DNS





1. HIGHLY AVAILABLE INTERNET-FACING DNS

Use OCI DNS for primary or secondary internet-facing DNS.


2. SECURE, INTERNAL DNS FOR OCI WORKLOADS

Use OCI DNS for internal workloads, keeping information secure from the
internet.


3. REQUESTS DIRECTED BASED ON LOAD, LOCATION, AND SOURCE

Distribute and direct requests across multiple regions based on the destination,
the health of the destination, and the location of the source.

USE PRIVATE DNS IN INTERCONNECTED VCNS AND ON-PREMISES

Use your own private domain names in OCI. With the private DNS service, you also
get DNS resolution between VCNs and between VCNs and on-premises networks.

DEPLOY A KUBERNETES CLUSTER WITH AUTOMATIC DNS MANAGEMENT FOR MULTIPLE
ENVIRONMENTS

Set up a single Kubernetes cluster deployment with OCI DNS zones and Kubernetes
ExternalDNS to configure a DNS solution for multiple environments.

OCI DNS SERVICE: MORE THAN PUBLIC NAMES

OCI offers several different ways to work with DNS to access your resources the
way you want, whether you require public or private name resolution.
