Service Overview

The DNS service converts domain names, which are convenient for humans to recognize, into numeric IP addresses that the system can identify, allowing access to services.
With the DNS service, users can easily register the desired domain and manage its DNS records themselves.

Features

• Easy Domain Registration: You can register and modify new domains via a web-based console. Without building separate DNS infrastructure or installing DNS solutions, you can easily create and manage domains through the web.
• Support for Various Records: You can configure various resource record types such as A, AAAA, CNAME, TXT, MX, SPF, and it automatically scales to handle large query volumes without user intervention.
• Convenient Hosting Environment Management: You can select and use a Public domain name, which is exposed to the Internet to provide web services, or a Private domain name, which is accessible only to designated internal users without an Internet connection, according to your usage environment and purpose.

Configuration diagram

Provided features

The DNS service provides the following functions.

• Hosting Zone Creation/Management: You can create and manage Public Hosted Zones that are accessible from anywhere via the Internet, and Private Hosted Zones that are not exposed to the Internet and are only accessible within a designated network environment.
• Public Domain Name Application: You can apply for a Public Domain Name that can be accessed from anywhere via the Internet.
• Support for various resource records: You can select and use record types that suit your environment and purpose.

Component

Private DNS

To manage private domain names for use only within a designated network environment without exposing them to the internet, you must first create a Private DNS. The Private DNS name is used uniformly across all regions within the account. It can be initially created in any region of the account, and later it can be activated in other regions using the same Private DNS name 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 the Private Hosted Zone information across all regions.

Hosted Zone

Private Hosted Zone allows you to create and manage domain names that can be used only in the network environment designated for VPCs connected to Private DNS. A Public Hosted Zone can manage the public domain name created through the Samsung Cloud Platform. Through a Hosted Zone, you can create and edit records that match your intended use.

Public Domain Name

You can apply for a Public Domain Name in partnership with Whois, the public domain name management provider. Public Domain Name can be purchased in one-year increments, and you can set or change the automatic renewal (in one-year increments) up to 7 days before the expiration date.

Constraints

The constraints of the DNS service are as follows.

Preceding Service

The DNS service has no prerequisite services.

1.1 - TLD List

TLD (Top-Level Domain) list

The following TLDs are available. When applying for a Public Domain Name, an annual fee is incurred that varies by TLD type.

1.2 - ServiceWatch Metrics

DNS sends metrics to ServiceWatch. The metrics provided by default monitoring are data collected at 5‑minute intervals.

Basic Metrics

The following are the basic metrics for the Private DNS namespace.

The indicators whose names are displayed in bold below are the key indicators selected from the basic indicators provided by Private DNS. Key metrics are used to configure service dashboards that are automatically built for each service in ServiceWatch.

Each metric indicates, via the user guide, which statistical values are meaningful when viewing that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. In the service dashboard, you can view key metrics using these primary statistical values.

2 - How-to guides

The user explains the items to verify before creating a DNS service through the Samsung Cloud Platform Console.

Preface before Using Private Domain Name Management

Before using Private Domain Name management, first verify the following items.

1. To manage private domain names for use only within a designated network environment without exposing them to the internet, you must first create a Private DNS.
2. The defined Private DNS name is used uniformly across all regions within the account. It can be initially created in any region within the account, and thereafter, in other regions, it is activated and used from the Private DNS list with the same Private DNS name.
3. You can optionally configure the VPCs you want to connect to Private DNS for each region. When first created or activated, no VPC is connected.
4. The Private DNS name may already be in use within the Samsung Cloud Platform, and you can verify its availability by performing a duplicate check when entering the domain name.
5. Hosted Zone information is shared across all regions. However, some detailed information (SRN, creator, modifier information) can only be viewed in the region where it was originally created.

General usage examples are shown below. For detailed usage instructions, refer to the How-to guides of the respective subservice.

Public Domain Name Management: Foreword Before Use

Before using Public Domain Name management, please check the following items first.

1. Public Domain Names intended for use on the internet can be managed through a Hosted Zone only for domain names that have been registered via the Samsung Cloud Platform.
2. The list of available top-level domains may change.
