Connect your clouds. Protect your business.
With IBM Cloud Sync, you can synchronize DNS data in real time with multiple DNS cloud providers. Cloud Sync moves data from DNS providers through APIs and the Cloud Sync data translation layer, allowing for seamless transfer of data without zone transfer limits.
Cloud Sync FAQ
IBM Cloud Sync is a multicloud DNS synchronization and automation service that continuously aligns DNS zones, records and traffic-steering configurations across any combination of cloud and on-premises DNS providers. Most of these providers do not support Zone Transfer (XFR) protocols—including AWS Route 53, Azure DNS, Google Cloud DNS, Cloudflare and other enterprise DNS systems.
It eliminates proprietary barriers between DNS ecosystems, ensuring bidirectional consistency, accuracy and resilience across hybrid and multicloud networks. Cloud Sync operates without relying on legacy zone transfer (XFR) protocols, enabling modern, API-driven synchronization at enterprise scale.
In today’s distributed environments, most enterprises operate across multiple cloud providers, each using its own proprietary DNS system. These disconnected platforms often cause configuration drift, increased operational overhead and reduced resilience.
IBM Cloud Sync was created to simplify multicloud DNS management by providing:
- Continuous, bidirectional synchronization across cloud and legacy DNS providers.
- Unified DNS visibility for operations teams managing hybrid environments.
- Automation that eliminates manual scripting and reduces human error.
This ensures DNS configurations stay consistent, scalable and resilient—no matter which clouds or vendors you use.
Cloud Sync connects to your DNS environments through secure APIs to continuously synchronize zones, records and metadata between providers. It normalizes proprietary configurations into a common model, allowing seamless interoperability across clouds.
For example, IBM Cloud Sync can keep DNS configurations synchronized between IBM NS1 Connect and other cloud DNS services such as AWS Route 53, Azure DNS or Google Cloud DNS. This synchronization ensures continuous consistency and eliminates the need for legacy zone transfers (XFR).
IBM Cloud Sync extends the functionality of IBM NS1 Connect Managed DNS and leverages the NS1 Connect Free Edition. If query volumes exceed Free Edition thresholds, an IBM NS1 Connect Managed DNS license might be necessary to extend capacity.
Unlike traditional DNS replication or zone transfer tools, Cloud Sync is API-driven, cloud-agnostic and continuously bidirectional. It provides real-time updates, automatic reconciliation of differences and full visibility into multicloud DNS health.
By removing reliance on manual scripts or one-way transfers, Cloud Sync offers:
- Real-time consistency across all environments.
- Faster recovery from DNS changes or incidents.
- Simplified operations through automation.
At launch, IBM Cloud Sync supports synchronization between IBM NS1 Connect and AWS Route 53. The roadmap includes Azure DNS, Google Cloud DNS and other enterprise DNS platforms, enabling unified synchronization across providers.
Yes. Cloud Sync is designed to interoperate with both cloud-native and legacy DNS systems. It can synchronize data from on-premises authoritative DNS servers or hybrid environments, ensuring consistency across traditional infrastructure and modern cloud deployments.
By synchronizing DNS configurations across multiple providers, Cloud Sync creates redundant and consistent DNS layers. This means that if one provider experiences downtime, other synchronized DNS endpoints continue serving traffic seamlessly—ensuring always-on availability and improved disaster recovery.
Absolutely. Cloud Sync automates what used to be manual and error-prone synchronization tasks. It:
- Eliminates the need for custom scripts.
- Reduces configuration errors and drift.
- Frees up IT and network teams to focus on innovation instead of maintenance.
EMA research shows that organizations automating DNS synchronization can achieve up to 30% fewer DNS errors and faster network recovery times.
Cloud Sync makes it easy to move or mirror configurations across multiple DNS providers. Because it’s API-driven and independent of proprietary transfer mechanisms, you can synchronize and replicate configurations across IBM NS1 Connect, AWS, Azure and GCP DNS environments—keeping your architecture flexible and portable.
Yes. Cloud Sync is built with enterprise-grade security, leveraging encrypted connections, API authentication and role-based access controls. All data exchanged between DNS systems is secured and adheres to IBM’s stringent cloud and data protection standards.
Setting up Cloud Sync is simple:
- Connect your existing DNS environments (cloud or on-premises) using secure credentials.
- Define synchronization pairs or groups.
- Cloud Sync automatically begins converting and synchronizing DNS records in both directions.
The setup process typically takes just a few minutes, with no custom scripts or zone transfer setup required.
Cloud Sync supports a wide range of record types—including A, AAAA, CNAME, MX, TXT, SRV and NS records—as well as metadata such as traffic steering, health checks and routing policies. The goal is to ensure complete parity and synchronization across providers.
Yes. Cloud Sync’s continuous synchronization means that every participating DNS provider maintains an up-to-date copy of your configurations, creating live backups across multiple clouds and ensuring faster recovery and business continuity.
Cloud Sync is designed for organizations that need to:
- Maintain consistent DNS configurations across hybrid and multicloud environments.
- Support multivendor or redundant DNS setups for higher availability.
- Simplify migration, M&A and replatforming projects.
- Ensure regulatory compliance and operational consistency across regions.
Yes. IBM Cloud Sync is a globally available managed service, accessible through the IBM Cloud platform and selected partner marketplaces. Future updates are set to expand support across regions and providers.
