From VPN Bottlenecks to CAD-Ready Cloud Storage: A Decision Memo for Architecture Firms

Background

A growing commercial architectural design firm had a familiar problem: its file environment had not kept pace with the business. What began as an in-house server setup for storing and managing AutoCAD files was workable in the early days, but as projects expanded and teams became more distributed, cracks in the system started to show.

Design staff depended on reliable access to large files. Leadership needed a setup that could support growth without increasing administrative overhead. Instead, the firm found itself dealing with VPN instability, hardware limitations, latency issues, and growing concern over backup reliability.

This is the kind of challenge many architecture firms face. The work is highly collaborative, file-intensive, and deadline-driven. When the storage environment slows down, the business slows down with it.

Requirements

Before choosing a new approach, the firm needed to define what a better solution actually had to deliver.

The must-haves were clear:

• Fast access to large AutoCAD files

• Reliable file locking to prevent conflicts

• Network drive mapping so users could work in a familiar way

• Minimal latency for remote and hybrid teams

• Offsite backup for stronger business continuity

• Less time spent maintaining servers and troubleshooting VPN issues

• A migration path that would not disrupt active projects

This was not simply a storage decision. It was an operational decision tied directly to productivity, data protection, and future scalability.

Options Considered

The firm looked at several common directions.

Option 1: Keep the existing server and VPN model
This would avoid change in the short term, but it would also preserve the same core issues. Users would still depend on VPN connectivity, IT would still have to manage aging infrastructure, and performance limitations would remain.

Option 2: Move files into a generic cloud sync platform
Tools like Box or OneDrive may work well for office documents, but architecture firms often need more than basic sync and share. Large design files, team collaboration, and application-specific workflows require stronger control over file access, locking, and performance.

Option 3: Adopt a cloud storage solution built for file-server-style access
This approach offered a better fit. Instead of forcing users to change how they work, it preserved familiar mapped-drive access while adding centralized cloud management, reliable backups, and support for large-file collaboration.

Decision

The firm selected CentreStack because it aligned with how the team already worked while solving the limitations of the old environment.

CentreStack gave the firm a more practical path forward by delivering:

• Real-time AutoCAD file locking to reduce overwrite risks and improve collaboration

• Mapped drive access so users could keep working from a familiar file structure

• On-demand caching to reduce the impact of latency on large files

• Centralized file access without the friction of a traditional VPN

• Reliable offsite backup support for stronger resilience and recovery

• Lower infrastructure burden compared with maintaining complex server hardware internally

Unlike generic cloud storage tools, CentreStack was better suited to firms that still need structured file access, predictable performance, and tighter control over business-critical design data.

Expected Impact

The expected gains were both immediate and long-term.

In the near term, the firm could reduce user frustration caused by unstable VPN connections and sluggish file access. Teams would spend less time waiting on files and fewer cycles dealing with version conflicts or disconnected sessions.

Over time, the firm would also benefit from a leaner IT model. Instead of continually investing time and money into maintaining hardware and patching together workarounds, the business could shift toward a more scalable and reliable storage strategy.

The larger value was strategic: the file environment would no longer act as a brake on growth.

Rollout Approach

A successful transition in an architecture environment depends on minimizing disruption. The migration path needed to be simple, predictable, and compatible with active design workflows.

A practical rollout typically includes:

• Identifying the most active project folders first

• Preserving folder structures and user permissions

• Enabling mapped-drive access for a smooth user experience

• Validating AutoCAD collaboration workflows before wider deployment

• Establishing backup and recovery policies alongside migration

This kind of phased approach helps firms modernize without forcing teams to relearn everything at once.

Why This Matters for Architecture Firms

Commercial architecture firms are under constant pressure to deliver quickly while managing increasingly complex files and distributed collaboration. Storage is no longer just an IT concern. It affects project timelines, design coordination, and the day-to-day experience of every user touching project data.

When remote access is slow, backups are uncertain, or file conflicts disrupt work, the impact extends far beyond the server room.

CentreStack addresses these issues with a model built around the realities of file-intensive businesses. It supports the familiar experience teams want while providing the control, performance, and resilience IT leaders need.

Conclusion

For architecture firms managing large AutoCAD datasets, the right storage decision is not about chasing the newest platform. It is about choosing a solution that supports real workflows, reduces operational drag, and prepares the business for growth.

This firm’s shift away from a fragile VPN-and-server setup reflects a broader industry need. Firms want modern file access without sacrificing structure, security, or usability. CentreStack offers that balance.
