DNS

Krutrim Cloud DNS is a fully managed, scalable, and high-performance Domain Name System (DNS) service. It enables you to create and manage hosted zones, configure DNS records, and route user requests to your applications and workloads running on Krutrim Cloud.

By integrating DNS management directly within the platform, you can connect your domains, APIs, and services to the internet or internal VPCs without relying on external DNS providers.

Introduction

What is Krutrim Cloud DNS?

Krutrim Cloud DNS provides domain name resolution for your hosted workloads. It converts user-friendly domain names like example.com into IP addresses that computers use to communicate.

The service offers:

  • Managed Public and Private Hosted Zones

  • Support for all standard DNS record types

  • Advanced Routing Policies (Simple, Weighted, GeoIP, Health Checks)

Core Concepts

DNS and Hosted Zones

A domain (e.g., example.com) is a unique name on the internet. A hosted zone is a container for the DNS records associated with that domain.

Krutrim Cloud DNS supports:

  • Public Hosted Zones (coming soon) – Resolve names over the internet.

  • Private Hosted Zones – Resolve names only within your selected VPCs. You can attach multiple VPCs to a private hosted zone.

Supported DNS Record Types

Record Type
Description
Example

A

Maps a domain name to an IPv4 address

example.com → 192.0.2.1

AAAA

Maps a domain name to an IPv6 address

example.com → 2001:db8::1

CNAME

Creates an alias to another domain

www.example.com → example.com

MX

Routes email to mail servers

example.com → mail.example.com

TXT

Stores text data, e.g. verification or SPF records

v=spf1 include:_spf.google.com ~all

NS

Defines the authoritative nameservers

ns1.krutrim.cloud.

Routing Protocols

Protocol
Description
When to Use

Simple

Sends all traffic to a single IP address. This is the default and easiest routing option.

Use when you have one server or endpoint handling all user requests.

Weighted

Splits traffic between multiple IP addresses based on the weight you assign to each one. Higher weight means more traffic goes to that server.

Use when you want to distribute traffic unevenly between servers — for example, to send more users to a higher-capacity server.

GeoIP

Routes users based on their location, such as country or region. Each location can be mapped to a specific server or IP.

Use when you want users to connect to the nearest data center for better speed and performance.

HealthPort

Routes traffic only to servers that are healthy and actively responding on a specific port. Supports both load balancing and failover by using Primary and Secondary IP sets — traffic goes to primary IPs under normal conditions and switches to secondary IPs if the primary ones fail.

Use when you need high availability and automatic failover between servers, such as for critical web or application services.

HealthURL

Checks the health of a server through an HTTP or HTTPS endpoint before routing traffic to it. If the endpoint is unavailable, traffic is redirected elsewhere.

Use for web applications or APIs where you want routing decisions based on real-time application health.

Advanced routing applies to A and AAAA records only.

Getting Started

Create a Hosted Zone

  1. Go to Networking → DNS in the Krutrim Cloud Console.

  2. Click Create Hosted Zone.

  3. Enter your Domain Name (e.g., example.com).

  4. Choose Public or Private:

    • Public (coming soon): Accessible over the internet

    • Private: Accessible only within a selected VPC

  5. (If Private) Select the VPC.

  6. Click Create.

Add DNS Records

Once the hosted zone is created:

  1. Open the hosted zone management page from the DNS dashboard.

  2. Go to Add Record.

  3. Select record type (A, CNAME, MX, TXT, etc.).

  4. Fill in the fields:

    • Record Name

    • Record Value(s)

    • TTL

    • Routing Protocol (for A/AAAA)

  5. Click Save Record.

  6. You can edit records from their entries in the DNS records table.

Managing Hosted Zones

View Hosted Zones

From the Hosted Zones landing page, you can:

  • View all your zones with filters for Public/Private

  • See record counts, type, and creation date

  • Manage or delete zones

Associate multiple VPCs with Private Zone

  1. Open a private hosted zone.

  2. Click Attach VPC.

  3. Select the desired VPC and save.

Only resources inside associated VPCs can resolve records from a private zone.

Best Practices

  • Use low TTLs (60–300s) for frequently updated records.

  • Use Weighted routing for smooth traffic distribution.

  • Avoid overlapping private zones across VPCs.

  • Leverage HealthPort/HealthURL for high availability.

  • Review records periodically to remove unused entries.

Billing

  • For Hosted Zones:

    • ₹18 per hosted zone per month for the first 25 hosted zones.

    • ₹8.81 per hosted zone per month for any additional hosted zones beyond 25.

  • For DNS Queries:

    • ₹35.25 per million queries per month for the first 1 billion queries.

    • ₹7.63 per million queries per month for queries beyond 1 billion.
