Private Cloud vs On-Premises PACS: Which Is Right for You?

Home » Private Cloud vs On-Premises PACS: Which Is Right for You?

Option 1: On-premises PACS

Traditionally, PACS servers have been installed inside the clinic. This provides fast local access to medical images because everything remains on the clinic’s own network.

For high-volume imaging providers, local performance can be excellent.

However, owning on-premises infrastructure also means the clinic becomes responsible for:

• Server hardware
• Power protection
• Cooling
• Cybersecurity
• Backups
• Disaster recovery
• Hardware replacement
• Ongoing maintenance

If the server fails, loses power or suffers a hardware fault, the clinic must have appropriate recovery plans in place.

Option 2: Public cloud PACS

Public cloud PACS stores imaging data within infrastructure owned and managed by a cloud provider.

This reduces the need for clinics to maintain physical servers while providing flexibility for remote access and storage expansion.

Public cloud can be an excellent solution, but healthcare providers should ask important questions before committing:

• Where is patient data stored?
• Does data leave Australia?
• Which country’s privacy laws apply?
• Is the platform designed specifically for healthcare?
• What happens if internet connectivity is interrupted?

Cloud is not simply about convenience. Patient privacy and data sovereignty should always be considered.

Option 3: Private cloud PACS

Private Cloud offers a different approach.

Instead of placing servers inside the clinic, the clinic owns its own dedicated infrastructure, but the equipment is securely hosted within a professionally managed data centre.

The hardware remains dedicated to that clinic. It is not shared with other organisations.

This gives healthcare providers many of the advantages of enterprise infrastructure without having to build and maintain their own server room.

Benefits typically include:

• Enterprise-grade security
• Redundant power supplies
• Backup generators
• Environmental monitoring
• Fire suppression systems
• High-speed internet connectivity
• Physical access controls
• Professionally managed facilities

At Medic Cloud, our private cloud solution allows clinics to retain ownership of their server infrastructure while removing the burden of housing and protecting critical equipment within the practice itself.

Option 4: Hybrid PACS

Hybrid PACS combines local infrastructure with cloud technologies.

Rather than relying entirely on one deployment model, hybrid allows clinics to take advantage of both.

For example:

• Images can be acquired and accessed locally for maximum performance.
• Critical data can be replicated to a secure private cloud environment.
• Remote reporting can continue without compromising local workflow.
• Disaster recovery becomes significantly more resilient.

For many healthcare providers, hybrid delivers the best balance of speed, security, flexibility and business continuity.

Why data sovereignty matters

As more imaging solutions move into the cloud, clinics need to understand exactly where patient information is stored and processed.

Healthcare providers manage highly sensitive personal information and remain responsible for protecting that information throughout its lifecycle.

Before selecting any cloud-based PACS solution, clinics should ask:

• Is patient data stored in Australia?
• Does any information leave Australia?
• Who owns the data?
• Is the data encrypted?
• Who can access it?
• What happens if the service ends?

These questions are just as important as storage capacity or subscription pricing.

Medic Cloud’s approach

After implementing diagnostic imaging solutions for healthcare providers across Australia, we’ve found there is rarely a perfect “cloud” or “on-premises” answer.

Instead, we focus on designing infrastructure around the clinic’s operational requirements.

For many organisations, this means combining technologies rather than choosing one over another.

Our preferred approach often involves a hybrid architecture supported by Medic Cloud’s private cloud infrastructure.

This allows clinics to:

• Retain ownership of their infrastructure.
• Avoid maintaining critical servers on-site.
• Benefit from enterprise-grade data centre facilities.
• Improve disaster recovery and business continuity.
• Scale storage as imaging volumes increase.
• Maintain secure remote access for authorised users.

Rather than forcing clinics into a standard solution, we design an environment that supports both current operations and future growth.

Final thoughts

Choosing a PACS is about far more than deciding where images are stored.

It is about balancing performance, reliability, security, compliance and long-term operational resilience.

While cloud and on-premises solutions both have their place, many Australian healthcare providers are finding that private cloud and hybrid architectures provide the flexibility needed for modern diagnostic imaging.

The best PACS solution is not necessarily the newest or the cheapest.

It is the one that allows clinicians to access images quickly, protects patient information, supports business continuity and grows alongside the practice.

FAQs

What is the difference between public cloud and private cloud?

Public cloud uses shared infrastructure owned by a cloud provider. Private cloud uses dedicated infrastructure assigned to a single organisation, often hosted within a secure data centre.

Is on-premises PACS still a good option?

Yes. Many clinics continue to benefit from on-premises PACS, particularly where high-performance local imaging workflows are required.

What is a hybrid PACS?

A hybrid PACS combines local infrastructure with cloud technologies, providing the performance of on-site systems together with the resilience and flexibility of cloud-based services.

Why is data sovereignty important?

Healthcare providers are responsible for protecting sensitive patient information. Understanding where data is stored and which privacy laws apply is an important part of selecting any cloud-based solution.

Why does Medic Cloud recommend private cloud?

Medic Cloud’s private cloud gives clinics the best of both worlds. Clinics retain ownership of their infrastructure while benefiting from enterprise-grade data centre security, redundant power, environmental protection, high-speed connectivity and professional infrastructure management—without the cost and complexity of maintaining critical servers on-site.
