Qumulo, a leader in enterprise-wide unstructured data management, has introduced Qumulo Stratus, a new multi-tenancy architecture designed to enhance data isolation, performance, and manageability across on-premises and public-cloud environments. Stratus integrates “shared-nothing” tenant segregation with cryptographically assured boundaries, allowing each tenant to operate as if on private infrastructure while leveraging the global efficiency of Qumulo’s scale-out DataCore and Cloud Data Fabric.
According to Douglas Gourlay, President and CEO of Qumulo, Stratus was developed in collaboration with agencies and enterprises that require stringent data separation, including national intelligence organizations managing classified information, global banks isolating regulated workloads, university consortia sharing large physics datasets, and life-sciences companies protecting genomic intellectual property. By cryptographically and operationally insulating tenants, Stratus aims to meet regulatory mandates from entities such as the National Institute of Standards and Technology (NIST) while reducing infrastructure expansion and administrative burdens. “Enterprises and public-sector agencies no longer have to choose between security and scale,” Gourlay stated. “Stratus erases that trade-off. We’ve fused uncompromising cryptographic isolation with the elasticity of cloud and the performance of bare-metal and accelerated computing, delivering a platform worthy of the world’s most sensitive data.”
Stratus is engineered to allow organizations to maintain strict data and infrastructure isolation while benefiting from the economic advantages and scalability of a shared-nothing data core. Key features of this architecture include:
* **Cryptographically Sealed Tenancy:** This feature supports Zero Trust and Least Privilege principles for data management. Each tenant can use independent key management systems and cryptographic keys, ensuring data at rest and in transit remains inaccessible, even to cluster administrators.
* **Disaggregated I/O & Data Planes:** Compute, cache, and protocol services are provisioned per tenant as containers, virtual machines, bare metal, or accelerated computing platforms. This design prevents “noisy-neighbor” contention and allows for independent scaling of performance from capacity.
* **Unified File & Object Access:** Stratus provides concurrent access through NFS, SMB, and S3 interfaces, enabling modern analytics pipelines and legacy applications to share data without the need for copies or gateways.
* **Cloud-Native & On-Premises Harmony:** A single global namespace spans data centers and major hyperscalers. This is supported by Qumulo’s real-time analytics and policy-driven data placement. With support for AWS, Azure, Google Cloud, and Oracle Cloud, Qumulo offers choice and flexibility in cloud service utilization.
* **Tenant-Specific Enterprise Services:** Per-tenant Active Directory, Domain Name Services, Hardware Security Modules, and SIEM/audit domains simplify Zero Trust compliance for environments in government, defense, financial services, healthcare, and service provision.
Kiran Bhageshapur, Chief Technology Officer at Qumulo, commented, “With Qumulo Stratus’s innovative cryptographic isolation technology, sensitive data remains protected while offering the flexibility and efficiency necessary for mission-critical operations. This enables both federal and enterprise customers to concentrate on their core missions with the confidence that they can meet their regulatory compliance and security objectives without compromising performance or scalability.”
Stratus is currently in limited availability and private preview. It is scheduled for general availability in Qumulo Core 8 for certified on-premises platforms, AWS, Microsoft Azure, Google Cloud, and Oracle Cloud in the second half of 2025. Further information will be provided during the Qumulo Stratus Webinar on Wednesday, June 23rd, at 10:00 AM PST.
Qumulo, recognized as a seven-time Leader in the Gartner Magic Quadrant for Distributed File and Object Storage, specializes in cloud data platforms. The company manages exabytes of data and serves over 1,000 production customers, enabling organizations to manage, store, curate, and protect their data across various industries.
