S&P Global’s Capital IQ Slashes Disaster Recovery to 15 Minutes Using AWS, NetApp, and Windows Clustering

S&P Global Market Intelligence has engineered a cross-region disaster recovery setup for its Capital IQ platform that can bring up a read-only instance in a secondary AWS region in as little as 15 minutes. The architecture, built on Amazon FSx for NetApp ONTAP, combines NetApp SnapMirror snapshots and FlexClone volumes with Windows Server Failover Clustering and SQL Server—a design that offers a practical blueprint for any enterprise running critical Windows workloads in the cloud.

The DR architecture in brief

At its core, the solution mirrors data from a primary AWS region to a standby region using Amazon FSx for NetApp ONTAP. ONTAP’s SnapMirror technology replicates volume snapshots across regions on a continuous basis. In normal operation, the secondary volumes remain offline. When a disaster is declared, automated workflows kick in: fresh FlexClone volumes are created from the latest Snapshot copy, Windows Failover Cluster nodes in the secondary region are brought online, and the cloned disks are presented to the SQL Server instances. The entire process completes within 15 minutes, delivering a read-only production environment that customers can use while primary systems are restored.

S&P Global Market Intelligence has not publicly released every implementation detail, but the company’s case study—presented at AWS events and in Amazon’s partner materials—confirms that the platform runs on Windows Server with SQL Server, using Amazon FSx for NetApp ONTAP as the shared storage layer. The combination of SnapMirror for low-RPO replication and FlexClone for instant, space-efficient database copies is what makes the sub-15-minute recovery time objective (RTO) possible.

What this means for Windows shops in the cloud

The most immediate takeaway is that rapid, cost-effective disaster recovery is no longer the exclusive domain of cloud-native microservices. Traditional Windows applications—especially those anchored on SQL Server and Windows Server Failover Clustering—can now achieve cloud-scale resilience without being rewritten.

For system administrators and architects: The architecture validates a pattern that many have been hesitant to adopt. Running a stretched Windows Failover Cluster across AWS regions has historically been cumbersome due to latency constraints and the lack of supported shared storage. Amazon FSx for NetApp ONTAP changes that by providing a multi-AZ, regional file system that can serve as cluster shared volumes (CSVs) and also replicate natively to another region. Admins who already manage on-premises NetApp FAS or AFF arrays will find the operational model familiar.

For database teams: SQL Server Always On availability groups already offer readable secondaries, but cross-region configurations often suffer from high latency and complex quorum models. The S&P design sidesteps those challenges by relying on storage-level replication and cloning, not database-level replication. The read-only instance is a point-in-time copy, which eliminates concerns about replication lag conflicting with user queries during an outage. It’s a pragmatic trade-off: the secondary is not a live replica, but it’s available fast.

For decision-makers: The business value is undeniable. Capital IQ is a flagship product delivering real-time and historical financial data to investment professionals. Downtime directly translates to reputational damage and potential revenue loss. A 15-minute RTO for a read-only failover keeps customers productive and buys time to perform a full recovery. Moreover, because the secondary region’s resources can be kept in a scaled-down state until needed, costs are contained.

How we got here: the evolution of Windows DR on AWS

For years, enterprises moving Windows workloads to AWS faced a fork in the road. They could lift-and-shift applications onto EC2 instances with block storage, using SQL Server Always On for high availability within a region, but cross-region disaster recovery often required custom scripts, third-party replication tools, or native backup and restore that took hours. Alternatively, they could re-platform onto cloud-native databases and container orchestrators, abandoning the Windows stack and the associated skills investments.

The introduction of Amazon FSx for NetApp ONTAP in 2021 changed the calculus. It brought an enterprise-grade, fully managed NAS service to AWS that behaves exactly like on-premises NetApp storage—complete with SnapMirror, FlexClone, deduplication, and compression. For the first time, Windows Failover Clustering on AWS could leverage a shared storage layer that was both cloud-native and cross-region capable. S&P Global Market Intelligence was among the early adopters, and its Capital IQ deployment has become a reference architecture for the combination.

Windows Server Failover Clustering itself has evolved, too. Starting with Windows Server 2016, Microsoft added Cloud Witness for quorum, simplifying multi-site clusters. In Windows Server 2019 and later, Cluster Sets and Storage Replica offered additional options, though neither provided the out-of-the-box global replication and instant clone capabilities that ONTAP brings. S&P’s choice to front the cluster with FSx for ONTAP effectively unifies the best of both worlds: the OS-level clustering manager and the storage-level replication engine.

The technical details that matter

While S&P Global Market Intelligence has not published a detailed step-by-step guide, the fundamental building blocks are well understood:

1. Primary region stack: A multi-AZ Windows Failover Cluster with SQL Server instances running on EC2. The cluster uses an FSx for ONTAP file system as clustered shared volumes. SQL Server data and log files reside on LUNs presented via iSCSI from ONTAP.

2. Replication: ONTAP SnapMirror is configured to replicate volumes to a secondary FSx for ONTAP file system in the destination region. Replication can be asynchronous with an RPO measured in minutes, depending on the change rate. SnapMirror’s block-level efficiency keeps the bandwidth footprint low.

3. Disaster declaration and orchestration: Likely automated through AWS Step Functions or System Manager runbooks. On trigger, the workflow stops replication, creates a FlexClone volume from the latest SnapMirror snapshot on the secondary side, mounts the clone to the standby Windows cluster nodes, and brings the SQL Server service online in read-only mode. Because FlexClone is a metadata operation, volume creation takes seconds regardless of data size.

4. Read-only availability: SQL Server can attach a database in read-only mode if the database files are marked appropriately. In a crash-consistent snapshot, the transaction log plays forward automatically during recovery, ensuring transactional consistency. Users access the secondary site via DNS switchover, an application-level redirect, or through a global load balancer.

5. Failback: Once the primary region is restored, replication direction can be reversed or a new base copy seeded. The cloned read-only instance can be discarded without impacting the underlying snapshot, keeping storage costs minimal.

Table: Key components and their roles

This architecture avoids single points of failure in the storage layer because FSx for ONTAP itself is a highly available, multi-AZ service within each region. The Windows cluster provides server-level redundancy locally; SnapMirror handles the regional fault domain.

What to do now: applying the lessons to your environment

If you manage Windows workloads on AWS and have been delaying a cross-region DR plan, the S&P Global case provides a tested template. Here’s how to get started:

• Assess your RPO/RTO requirements: The 15-minute read-only target is aggressive but achievable primarily because FlexClone eliminates data copy time. Your own RTO will depend on automation maturity, Windows cluster boot times, and DNS propagation. Start by benchmarking a manual process, then automate.
• Engage AWS about FSx for ONTAP: If you haven’t used it, request a solutions architect session. The service supports Multi-AZ file systems with automatic failover within a region, and cross-region replication is a one-to-one mapping between file systems. Review the throughput and capacity limits to ensure they align with your dataset.
• Rehearse the networking: Cross-region VPC peering or Transit Gateway must be pre-configured. Ensure that the secondary cluster nodes can access the FSx file system’s endpoint and that SQL Server client traffic can route to the new region. Security groups and Active Directory trusts need to be in place.
• Master FlexClone operations: In a non-production environment, practice taking a SnapMirror snapshot, cloning it, and attaching the clone to a Windows instance. Document the exact PowerShell or AWS CLI commands, and build them into an automation pipeline.
• Decide on a DNS strategy: Route 53 health checks and failover routing policies can direct users to the read-only endpoint automatically. Alternatively, an application-layer gateway can recognize the DR state and route accordingly. Test the full cutover experience.
• Plan for data consistency: SnapMirror snapshots are crash-consistent. For applications that need application-consistent backups, integrate VSS (Volume Shadow Copy Service) at the Windows level or leverage ONTAP’s SnapCenter with the included application plug-ins. A crash-consistent read-only SQL Server is acceptable for most analytical workloads, but verify with your stakeholders.
• Budget carefully: Cross-region data transfer costs and the secondary FSx for ONTAP file system’s storage capacity will be the primary expenses. Use AWS Calculator to model the cost of replication traffic plus storage. Because FlexClone volumes share physical blocks with the parent snapshot, they consume little additional space, so the ongoing DR footprint is mainly the snapshot storage.

Outlook

S&P Global’s achievement underscores a broader industry shift: hybrid resiliency patterns are becoming standard. AWS and NetApp continue to deepen their integration; expect to see more automation templates and reference architectures published in the coming months. Microsoft is also advancing Windows Server and SQL Server capabilities for the cloud, with Azure-inspired features like Storage Replica making their way into on-premises and multi-cloud deployments. For Windows professionals, the message is clear: you no longer have to compromise between the operational familiarity of your stack and the disaster recovery agility that the business demands. The blueprint is there; it’s time to put it to work.
