IBM has unveiled IBM Cloud Sync, a cloud-based service designed to help enterprises reduce the risk of DNS outages and safeguard corporate assets across multicloud environments.

The service enables real-time, bidirectional synchronization of DNS zones, records, and traffic-steering data between IBM’s NS1 Connect package and cloud DNS providers. It also offers policy translation, automated backups, and authentication controls, allowing businesses to quickly restore services in case of disruptions.

NS1 Connect’s dynamic DNS capabilities optimize traffic routing based on factors like availability, performance, and time-of-day. With Cloud Sync, enterprises can implement redundant DNS solutions and maintain advanced features such as traffic steering, even across multiple cloud vendors.

Currently, Cloud Sync supports Amazon Route 53, with future updates expected to expand support to Microsoft Azure, Google Cloud, Cloudflare, and other DNS services. IBM emphasizes that the service reduces reliance on manual scripts or custom tooling, which are error-prone and difficult to maintain.

An NS1 Connect Managed DNS account is required for synchronization, with a free edition available for lower query volumes. Cloud Sync allows organizations to focus on innovation and business value rather than DNS infrastructure management.

Translating network configurations and data between clouds is a major engineering challenge. IBM Cloud Sync, part of the NS1 Connect portfolio, offers a promising solution, according to Shamus McGillicuddy, vice president of research at Enterprise Management Associates (EMA), in the white paper “Network Config Synchronization Across Multi-Cloud Networks: Application Resilience and Security.”

“Even if an organization standardizes on a third-party firewall across clouds, they still rely on native networking services from each provider for functions like load balancing, routing, subnets, and DNS. In other words, multi-cloud network vendor sprawl remains difficult to eliminate,” McGillicuddy added.
