Rethinking Business Continuity in a Distributed World
Reflections from Cloud Field Day 23 on how Qumulo is reshaping continuity—from architecture to economics.
The most pressing conversations about data resilience no longer begin with backups. They begin with storms.
Sometimes literal—cyclones, floods, bushfires. More often not. Power failures, ransomware, cloud region outages, infrastructure decay. What’s changed is not just the technology, but our posture toward failure itself. And in this shift, Qumulo offers a timely, if not overdue, reframing: don’t wait for the storm to hit. Design your systems as if it already has.
Elasticity Is Not a Feature. It’s a Philosophy.
Cloud computing has long traded on elasticity as a convenience—scale up when needed, scale down when idle. But few vendors have stretched this idea into the domain of continuity itself. Qumulo’s proposition is deceptively simple: treat elasticity as a resilience strategy.
What if a cold standby system could behave like a hot one in minutes? What if failover didn’t require switching anything at all? What if continuity was already live?
In one demonstration, a municipal government faced a rising storm—literally. A hurricane threatened their primary data centre. Instead of initiating a complex cutover, employees were handed Intel NUCs—small enough to fit in a bag, powerful enough to run critical workloads. They went home, plugged in, and resumed operations. No VPNs. No reconfigurations. No downtime.
Behind the scenes, Qumulo’s cloud-native system acted as the central lifeboat. The data wasn’t failed over; it was already flowing. Edge devices became spokes—cached, coherent, and calm. This wasn’t disaster recovery. It was continuity by design.
🛠️ Architectural View
Qumulo’s elasticity model is grounded in a decoupled architecture: object storage provides durability, while compute is ephemeral and stateless. In their Field Day demo, terabit-scale throughput was achieved within minutes by spinning up hot compute against cold-tier object storage. This is possible through block-level change tracking and predictive neural caching—no full rehydration or file copy needed. The metadata layer resides in both compute and object storage, allowing cold systems to turn hot instantly without loss of fidelity or namespace.
Storage That Doesn’t Panic
Traditional disaster recovery has always been an architecture of doubt.
“When do we fail over?” “How much time do we have?” “What’s the cost if we’re wrong?”
Qumulo eliminates the question entirely. Its system continuously synchronises at the block level, with caching intelligence that learns where performance is needed—before it’s requested. The neural cache builds a heat map across file types, directory patterns, and user activity, serving hot reads before users know they need them.
In the hurricane scenario, data written on-prem was streamed to the cloud in real time. No backup windows. No bulk replication. Just live file systems with live edits—resilient to local failure and indifferent to location.
“Don’t wait to climb into the lifeboat,” one speaker noted. “It’s already floating.”
🛠️ Architectural View
Qumulo maintains continuity using 4K block-level delta tracking with asynchronous streaming to cloud clusters. Their neural cache engine applies adaptive strategies per directory, informed by real-time inference over access patterns and file types. In the demonstration, an Intel NUC wrote data directly to a cloud-backed file system, achieving high WAN bandwidth utilisation through congestion control and protocol-level optimisation. While continuity can be preserved even when edge nodes act as cache-only devices, Qumulo explicitly noted that data loss is possible if a connection is severed before the local cache is flushed to the cloud . The system’s strength lies in how rapidly it flushes data in real time, reducing but not eliminating this risk.
The Economics of Enough
The best disaster recovery systems have often been judged by their redundancy—how much duplicate infrastructure can you afford to leave idle? Qumulo reframes that metric. Continuity doesn’t require excess. It requires design.
By allowing cold storage to operate as hot when needed—and charging accordingly—Qumulo offers not just cost savings, but cost realism. You pay for performance only when you need it. You don’t duplicate data across zones unless it makes business sense. You don’t maintain mirrored systems waiting for the worst day of the year. You prepare once—and then adapt.
It’s not minimalism. It’s maturity: infrastructure that responds dynamically, not defensively.
🛠️ Architectural View
Qumulo optimises cost and performance through just-in-time compute activation. Object storage remains always-on, while compute nodes can be spun up only when needed—delivering significant savings, particularly at petabyte scale. In one healthcare use case, API read costs dropped from $800,000 to just $180 by optimising object storage interactions through bin-packing and caching. Cold-to-hot elasticity may see further efficiency gains as Qumulo develops support for ARM-based compute, including AWS Graviton—currently under development for customers seeking energy-efficient performance at scale.
From Data Storage to Strategic Presence
The shift isn’t just technical. It’s philosophical.
Data resilience has too often been framed as a failover process. But in a world where work happens across sites, clouds, and time zones, resilience looks more like presence: always available, always consistent, regardless of who is asking or from where.
Qumulo’s architecture reflects that mindset. It doesn’t merely store unstructured data. It activates it—across cloud zones, edge devices, and on-prem caches. A file edited from a NUC in a storm zone is immediately available to analysts in the cloud. Not mirrored. Not copied. Just present.
This design becomes even more powerful in multi-cloud and AI scenarios. In one example, drone telemetry was streamed simultaneously to multiple cloud providers using both NFS and SMB protocols—demonstrating real-time ingest across distributed platforms. Elsewhere, media studios edited petabyte-scale footage across five continents, while edge AI models trained and retrained on real-world input without ever touching a shared drive.
The file system doesn’t ask permission. It simply continues.
Unified, Not Just Available
What distinguishes Qumulo isn’t just its performance or pricing. It’s the principle of unification. Any hardware. Any cloud. A single file system, distributed but coherent.
Users don’t need to know whether the data resides on-prem, in AWS, or in Azure. They interact with a consistent view of the file system. Access control, metadata, and consistency behave as one. A director in Sydney, a data scientist in Singapore, and a systems engineer in Virginia all interact with the same file—accurately, concurrently, and without conflict.
This isn’t availability. It’s integrity at scale.
The architecture supports not just operations, but trust—internally across teams, and externally across partners. It allows data to flow without loss of fidelity, and without resorting to file copying as a form of collaboration.
🛠️ Architectural View
Qumulo maintains a single authoritative namespace across distributed clusters using a strict consistency model. Metadata, ACLs, and file locks are synchronised in real time, allowing collaborative editing without file conflicts or eventual consistency drift. Unlike object gateways or sync-based NAS systems, Qumulo avoids copy-and-paste workflows by ensuring every node—on-prem or cloud—sees the same file system state. This is critical for regulated workloads and distributed production pipelines.
Cold-to-Hot, On Demand
One of the most quietly disruptive features of Qumulo’s system is its ability to make cold storage behave like hot—within minutes.
Need to spin up high-throughput access from archive-tier object storage? The system is already prepared.
It’s not just about savings—though the economics are substantial. It’s about realistic architecture: systems that are live when needed, silent when not, and always ready without overprovisioning.
In the aftermath of the hurricane demo, users returned to the office. The system reconnected. Data synced. But had the primary site been lost entirely, no rehydration would have been required. The cloud had already taken ownership.
Final Thought
Resilience today is less about backup and more about trust in design. The Qumulo approach—distributed, intelligent, elastic—ensures that the location of data is never a dependency, and its movement never a panic.
The hurricane analogy is memorable because it’s tangible. But storms come in many forms. The question isn’t whether your data systems can weather them. It’s whether they’ve already started moving before the clouds gather.
In a world this distributed, failure is not an exception.
It’s the assumption.
And continuity isn’t something you activate. It’s something you architect.
