1. 🔎 Introduction

Xloud XAVS OpenStack includes a fully integrated DNS as a Service (DNSaaS) solution, powered by OpenStack Designate, enabling seamless, automated DNS management across tenant environments.

Designate operates as a native core service of the platform—no additional VMs or customer deployments are needed. DNS records for virtual machines and network interfaces are automatically created, updated, and deleted based on lifecycle events, while maintaining synchronization with external enterprise DNS providers such as:

• Infoblox
• Microsoft DNS
• BlueCat
• Bind9 / ISC DNS
• Other RFC-compliant or API-capable DNS systems

2. 🧱 Architecture Overview

🔹 DNSaaS Workflow (Fully Managed)

1. Customer launches VM → Hostname, IP, and domain info captured at provisioning time.

2. Designate triggers DNS automation → Automatically creates A, PTR, and CNAME records in tenant or project-assigned DNS zones.

3. External DNS Integration (Optional) → Designate updates enterprise DNS providers as the authoritative source.

4. Lifecycle-Aware Management → DNS records are modified or deleted automatically on VM updates or termination.

5. Multi-Zone and Multi-Tenant Capable → DNS zones are isolated per project and scoped by access control policies.

3. ✨ Key Features

• 🔁 Automated Record Management DNS entries are created and deleted based on VM lifecycle—zero manual steps.

• 🌍 External DNS Provider Integration Updates can be forwarded to enterprise DNS platforms including Infoblox and Microsoft DNS.

• 🔐 Multi-Tenant DNS Isolation Each project can have its own DNS zones with scoped access and visibility.

• 📘 Full Support for Forward and Reverse Zones Designate handles A, AAAA, CNAME, and PTR records.

• ⚙️ Integrated, No VM Setup Required DNSaaS is a fully managed service inside Xloud XAVS—no tenant-side setup needed.
