Service Overview

The DNS service is a service that converts domain names, which are easy for humans to recognize, into IP addresses composed of numbers so that systems can identify them, allowing access to services.
Through the DNS service, users can easily register desired domains and manage domain records themselves.

Features

• Easy Domain Registration: New domain registration/change management is possible through a web-based console. You can easily create and manage domains through the web without building a separate DNS infrastructure or installing a DNS solution.
• Various Record Support: You can set various resource record types such as A, AAAA, CNAME, TXT, MX, SPF, etc., and automatically scale to handle large query volumes without user intervention.
• Convenient Hosting Environment Management: You can select and use Public domain names that provide web services exposed to the Internet and Private domain names that can only be used by designated internal users without Internet connection according to the environment and purpose.

Provided Functions

The DNS service provides the following functions.

• Hosted Zone Creation/Management: You can create and manage Public Hosted Zones that can be accessed from anywhere through the Internet and Private Hosted Zones that can only be accessed in designated network environments without exposure to the Internet.
• Public Domain Name Application: You can apply for a Public Domain Name that allows access from anywhere through the Internet.
• Various Resource Record Support: You can select and use record types according to the usage environment and purpose.

Components

Private DNS

To manage Private domain names for use only in designated network environments without exposure to the Internet, you must first create a Private DNS. Private DNS names are commonly used in all regions within an Account. They can be created for the first time in any region within the Account, and thereafter can be activated with the same Private DNS name in other regions from the Private DNS list. You can select the VPC to connect to Private DNS for each region. By using a common Private DNS name, you can share and manage Private Hosted Zone information across all regions.

Hosted Zone

Private Hosted Zone allows you to create and manage domain names that can only be used in designated network environments targeting VPCs connected to Private DNS. Public Hosted Zone allows you to manage Public Domain Names created through Samsung Cloud Platform. Through Hosted Zone, you can register and modify records according to your purpose.

Public Domain Name

You can apply for a Public Domain Name in conjunction with Whois, a Public Domain Name management company. Public Domain Name can be purchased in one-year units, and you can set or change whether to automatically renew (in one-year units) up to 7 days before the purchase period ends.

Constraints

The constraints of the DNS service are as follows.

Prerequisite Services

The DNS service has no prerequisite services.

1.1 - TLD List

TLD (Top-Level Domain) List

You can use the following TLDs. Different annual usage fees apply by TLD type when applying as a Public Domain Name.

1.2 - ServiceWatch Metrics

DNS sends metrics to ServiceWatch. The metrics provided by basic monitoring are data collected at a 1‑minute interval.

Basic Indicators

The following are the basic metrics for the DNS namespace.

2 - How-to guides

This explains what to check before creating a DNS service through the Samsung Cloud Platform Console.

Before Using Private Domain Name Management

Verify the following before using Private Domain Name management.

1. To manage Private domain names for use only in specified network environments without exposing to the internet, you must first create a Private DNS.
2. The defined Private DNS name is used commonly across all regions within the Account. It can be created initially in any region within the Account, and thereafter in other regions, you activate and use it with the same Private DNS name from the Private DNS list.
3. You can selectively set VPCs to connect to Private DNS per region. There are no connected VPCs at the time of initial creation or activation.
4. The Private DNS name may already be in use within Samsung Cloud Platform, and you can check whether it is in use through duplicate checking when entering the domain name.
5. Hosted Zone information will be shared across all regions. However, some detailed information (SRN, creator, modifier information) can only be verified in the region where it was initially created.

A general usage example is as follows. For detailed usage instructions, refer to the How-to guides of the corresponding sub-service.

Before Using Public Domain Name Management

Verify the following before using Public Domain Name management.

1. For Public Domain Names to be used in internet environment, management through Hosted Zone is only possible for domain names applied for through Samsung Cloud Platform.
2. The list of available top-level domains may change.

An example of general usage procedure is as follows. For detailed usage instructions, refer to the How-to guides of the corresponding sub-service.
