When evaluating a new practice management system, one of the first questions you'll encounter is whether it's cloud-based or server-based - sometimes called "on-premise." It sounds technical, but the implications are practical: how your team accesses the system, who maintains it, what happens if something goes wrong, and how much it costs to run.
Most industries made this transition years ago. GP practices, law firms, accountancy software - the shift to cloud is well established. Veterinary software is one of the last sectors where legacy, server-based systems are still common. That's changing, but it's worth understanding what you're comparing.
What Is a Server-Based (On-Premise) Veterinary PMS?
The traditional server-based practice management systems runs on physical hardware - your data is stored in computers and servers physically stored within your practice. Think of it as a dedicated machine, often kept in a back office or storage room, that your PMS lives on. Your team accesses the software through computers connected to that machine, usually within the same building.
You own that hardware outright. That means you buy it, maintain it, update it, and eventually replace it - typically every five to seven years, at a cost of several thousand pounds. It needs physical space, stable power, and someone responsible for keeping it running. If it breaks, so does your system.
In practice, this means:
- Updates to the software need to be installed manually - often by a technician, out of hours
- If the hardware fails and you haven't backed up recently, data can be lost
- Accessing the system remotely - from home, another site, or out of hours - is limited or complicated
- There is no subscription fee, but hardware replacement and IT support costs add up over time
What Is Cloud-Based Veterinary Software?
Cloud-based software isn't stored in your practice at all. It lives on remote servers — large, secure data centres owned and managed by specialist infrastructure providers — and you access it through the internet. Think of how you access your online banking or emails: the data isn't on your laptop, but it's securely available whenever you need it.
The provider manages everything behind the scenes: storage, security, updates, and backups.
In practice, this means:
- Your PMS and all client data can be accessed securely from anywhere - the practice, at home, on the road,
- Software updates happen automatically, in the background, with no downtime or manual installation
- Your data is backed up continuously - you don't have to think about it
- There is no hardware to buy, maintain, or replace
- You pay an ongoing subscription rather than a large upfront cost

Is Cloud Storage Secure for Veterinary Practices?
It's the right question to ask. Client data, clinical records, and financial information all need protecting.
Reputable cloud providers build security as a foundation, not an afterthought. Leading infrastructure platforms like AWS - which Lupa OS is built on - use end-to-end encryption for data in transit and at rest, continuous security monitoring, and distributed storage across multiple secure data centres. It's the same set up trusted by the NHS, financial institutions, and government systems.
No system is completely risk-free. But a well-maintained cloud platform offers more consistent, actively monitored protection than most on-premise setups - where security relies on your own backup discipline and IT maintenance schedule.
Which Is Right for Your Practice?
For most practices today, cloud-based software is the more practical choice. Lower upfront cost, no hardware burden, remote access, and automatic updates make it easier to run - particularly as practices grow, take on associates, or operate across multiple sites.
Server-based systems still suit practices with unreliable internet connectivity, or those with a strong preference for keeping infrastructure entirely in-house.
Lupa OS is a cloud-based practice management platform built on AWS infrastructure. Because it's cloud-based, it runs faster and more reliably than traditional systems. Whether you're a single site or expanding across multiple locations, your team can access client records and clinical data consistently across sites, which means a smoother experience for your staff and a better one for your clients. If you're evaluating your options, we're happy to walk you through how it works.
