With rising patient expectations, growing data volumes, and increasing pressure to innovate and cut costs, healthcare leaders are forced to reimagine how their organizations operate. Cloud computing has emerged as more than an IT upgrade; it’s a strategic cornerstone that fuels agility, unlocks real-time insights, and powers personalized, data-driven care.
But don’t rush into cloud migration without thorough preparation, assuming that cloud vendors will do you justice. Some of them might not even understand the specifics of your industry.
This article will help you discover different cloud deployment models and recognize the risks associated with adopting cloud computing in healthcare. It will also give you some tips on how to get started.
What is cloud computing in healthcare, and how is it used?
According to Microsoft, cloud computing is the delivery of computing services, such as storage, servers, analytics, and software, over the cloud (via internet connection).
It is easier to grasp the concept of the cloud when comparing it to the on-premises model.
The main difference between the two is where your hardware, software, and applications are located. In the case of on-premises deployment, all the infrastructure remains on the premises of the user company, which is also responsible for maintenance. With cloud solutions, the infrastructure is housed offsite, and it’s the cloud vendor who takes care of security and maintenance. Below is a more detailed comparison.
The idea of network-based computing emerged in the 1960s, but cloud computing as we know it was introduced by Google CEO Eric Schmidt in 2006 at the Search Engine Strategies Conference. Speaking of the history of cloud computing in healthcare, the concept has been around for a while, but because the healthcare sector is heavily regulated, the adoption has been slow. According to Forbes, medical organizations store 47% of their sensitive data in the cloud, while other industries store on average 61%.
But as the adoption grows, the global healthcare cloud computing market expands. It was valued at $40.43 billion in 2024 and is expected to surpass $89 billion by 2029, growing at a CAGR of 18.2%. Some forecasters are even more optimistic and go as high as $233 billion by 2032.
Cloud computing deployment models for medical facilities
There are three main cloud deployment models: private, public, and hybrid.
-
Public cloud. The cloud’s storage and computational resources are reachable over the Internet and can be used by the general public. This model serves multiple clients benefiting from shared infrastructure.
-
Private cloud. The cloud’s resources are offered exclusively to one particular client and are accessible over a private network. This can either be managed by the cloud vendor or by the client. This model is best suited for organizations with no tolerance for downtime and with unpredictable, constantly changing needs. This deployment option is mostly appreciated for its security and scalability, but it is also the most expensive model; it only works with a knowledgeable internal IT team in place, and sudden spikes in traffic can bring this model down.
-
Hybrid cloud. This model combines the private cloud model with one or more public cloud solutions. Another option is mixing cloud computing with on-premises servers. This approach allows healthcare organizations to store the most sensitive data in the private cloud while benefiting from the computational resources of the public cloud.
Other, less commonly used models include governmental cloud, which is owned and managed by the government, the community model, which is used by a group with common interests, and distributed cloud, where public cloud services are spread across physical locations.
Cloud service models: the difference between SaaS, PaaS, and IaaS in healthcare
Cloud computing in healthcare can be deployed in three main service models: SaaS, PaaS, and IaaS.
-
Software as a service (SaaS). Healthcare data is hosted in the cloud and is accessible over the internet. Cloud vendors have control over the environment and users’ data.
-
Platform as a service (PaaS). Cloud vendors deliver the platform where users can run their applications.
-
Infrastructure as a service (IaaS). Cloud vendors supply computing resources while users retain control over the infrastructure.
| What it offers | Best suited for | Cloud vendor controls | Healthcare organization controls | Most common applications | |

Benefits of cloud computing in healthcare
Adopting cloud computing in healthcare isn’t just a technological upgrade—it’s a strategic shift that unlocks transformative value across the organization. From cutting costs to enhancing patient care, here are the key benefits of cloud computing for healthcare organizations.
1. Reducing costs and achieving financial sustainability
Cloud computing in the medical field helps organizations lower costs while creating room for smarter investments. By moving away from expensive on-premises infrastructure, healthcare providers avoid large capital expenses and the need for dedicated IT staff and maintenance. With a pay-as-you-go model, hospitals pay for what they actually use—no long-term contracts or unused capacity.
Cloud computing can reduce IT costs in hospitals by up to 40% compared to traditional data centers, freeing up resources that can be reinvested in innovation, such as AI-driven diagnostics or expanding patient services.
2. Enhancing security
In healthcare, security isn’t just about protecting data—it’s about protecting patient trust and the organization’s reputation. Cloud providers go to great lengths to ensure data security in healthcare cloud systems. They offer advanced, built-in security features like encryption, threat detection, and automated patching that often surpass what on-premises systems can deliver.
Cloud vendors have highly qualified technical experts, which most healthcare organizations simply can’t recruit. These professionals conduct penetration testing and other preventive measures. To improve cloud security in healthcare, vendors also allocate the time and budget to monitor vulnerabilities 24/7 and offer automated backups and disaster recovery options.
Just as importantly, leading cloud platforms are designed to meet strict compliance standards like the Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulations (GDPR). It reassures patients, partners, and regulators that their data is handled responsibly, and it reinforces your brand as a trustworthy, secure provider.
3. Offering scalability and flexibility
Scalability is about reducing or adding resources to meet changes in demand.
Organizations deploy cloud computing for scalable healthcare infrastructure. It gives the agility to respond quickly to changing demands—whether it’s a seasonal flu surge, a sudden public health crisis, or launching new digital services. With cloud infrastructure, providers can scale computing power and storage up or down on demand, without the delays or costs of purchasing new hardware or upgrading software.
4. Unlocking powerful analytics
Healthcare cloud computing transforms the vast ocean of data into actionable intelligence. With healthcare organizations generating over 50 petabytes of data annually—most of it unused—cloud-based analytics and AI unlock insights that were previously out of reach. These advanced tools aggregate and process both structured and unstructured data in real time, helping clinicians identify gaps in care, personalize treatment plans, facilitate patient engagement, and make faster, more accurate diagnoses.
Beyond clinical improvements, cloud-powered analytics also drive data-driven decisions across operations—streamlining workflows, predicting patient needs, and optimizing resource allocation.
For example, Hygenix Inc., a patient safety tech company based in Connecticut, teamed up with ITRex to develop a platform of IoT cloud-connected devices to monitor hand hygiene of its healthcare staff. The platform gathered data on hand hygiene events, analyzed it, and produced reports to encourage better hygiene practices. After deployment, the participating hospitals witnessed over a 70% increase in hand hygiene compliance within just one week.
5. Ensuring data interoperability
Interoperability is critical in modern healthcare, and the cloud makes it achievable at scale. By integrating data across systems, providers, insurers, and pharmaceutical partners, healthcare cloud computing eliminates data silos. Now, clinical data can be securely accessed and shared—no matter where it comes from—ensuring seamless collaboration among everyone involved in a patient’s care.
When organizations achieve interoperability through cloud computing in healthcare, they get a complete view of the patient’s journey, improving care coordination across departments and organizations. It enhances the patient experience, reduces redundancies, and supports higher-quality, more personalized care.
Real-life examples of cloud computing in healthcare

The National Health Service (NHS) England moved its major services like NHS 111 and the NHS App to the cloud with AWS and Azure. They have saved millions of pounds per year (about 40%) and gained the flexibility to manage services more efficiently, respond faster to demand, and keep everything running smoothly across the board.
Risks of cloud computing in healthcare
While the benefits of cloud computing in healthcare are compelling, they don’t come without challenges. Understanding and proactively managing these risks is essential for healthcare leaders to ensure a secure and sustainable cloud transformation.
1. Lost control and cloud outage
After adopting cloud computing in healthcare and migrating their data, medical facilities give up control over their assets. This is particularly apparent in the SaaS model. This puts medical facilities in a position where they are still obliged to protect the data while having no control over it and relying on cloud providers to implement the necessary precautions to keep their assets safe.
Also, cloud services can go down, so hospitals need to find a way to operate under these conditions while waiting for the cloud vendor to bring the services back online. Downtime doesn’t only result in productivity loss but can also be a life-or-death situation in some extreme cases.
Solution:
There are several steps hospitals can take to minimize the negative impact from cloud outages. First and foremost, define and implement a disaster recovery plan and deploy a backup infrastructure in another country/region. Read your service level agreement carefully. Are you guaranteed 99.9% uptime? The 0.1% downtime translates into eight hours a year without service.
Alternatively, clinics can adopt a multi-cloud approach and rely on several vendors. Even if one system goes down, the others will still be working.
2. Vulnerabilities introduced by legacy systems
Legacy systems remain a large part of healthcare IT infrastructure. According to recent research, 53% of medical devices operate on legacy platforms. And even though modern technology would be more effective in the long run, many medical facilities don’t have the opportunity to replace their legacy systems before moving to healthcare cloud computing.
Connecting such equipment to the cloud will introduce additional risks. For example, some legacy systems are running on obsolete machine code and may contain security loopholes.
Solution:
To protect cloud deployments, medical facilities need to identify and address any security vulnerabilities introduced by legacy equipment. Use network segmentation to isolate high-risk devices, contain any potential breaches, and limit their negative impact on the entire network.
3. Compliance issues
Patient data is sensitive information protected under regulations like HIPAA and GDPR. Violating these standards will not only ruin the hospital’s reputation but will also have financial consequences. An intentional HIPAA violation will result in a $50,000 minimum fine, and it can reach up to $250,000 as a criminal penalty. Violating organizations might also be obliged to pay restitution fees to the victim and serve jail time if deemed appropriate.
Healthcare organizations need to ensure compliance during and after cloud migration. We are speaking about data storage security, access, patient privacy, breach notifications, etc.
Solution:
Not all cloud computing in healthcare solutions and vendors can ensure the same degree of compliance. Moreover, a compliant cloud vendor can rely on tools from external vendors as a part of their security strategy. Even though the primary provider is compliant, the secondary one might not be, which compromises the overall compliance of the cloud.
So, healthcare organizations need to choose cloud offerings carefully. The majority of compliant vendors will openly explain how their solutions meet the desired regulations and sign all the required documents.
As Jeff Thomas, CTO at Forward Health Group, said, “Is the vendor you choose willing to sign a business associate agreement? If they hesitate or don’t know what that is, they aren’t the right vendor to choose because they don’t understand your healthcare compliance needs when it comes to HIPAA.”
4. Weak organizational preparation
Before adopting cloud computing, healthcare organizations need to be fully prepared. If their systems and processes aren’t well documented and no one has a grasp on how the current system would translate into the cloud, this needs to be fixed before proceeding to full-scale deployment.
Without a clear cloud strategy, defined goals, and cross-functional alignment, healthcare organizations often struggle with fragmented implementations and duplicated efforts. This, in turn, leads to increased costs, operational inefficiencies, and resistance from staff who aren’t properly trained or engaged in the transformation process.
Solution:
Healthcare organizations need to prepare for the cloud and adapt to it. They need to conduct technology assessments, analyze their platforms, prioritize what they need to move, and get the data ready for migration.
Leadership must treat cloud adoption as an enterprise-wide initiative—not just an IT project. This includes investing in change management, upskilling teams, aligning stakeholders, and ensuring that cloud migration supports broader clinical and business objectives.
5. Yet again… security
When it comes to cloud computing, the medical sector is experiencing what Accenture calls “security paradox.” The consulting firm’s research revealed that 60% of the surveyed CIOs recognize the security-related benefits of cloud computing in healthcare, yet more than two-thirds of the respondents retain 80% of their data on premises. Accenture attributes this to the mindset of healthcare managers and the C-suite. They don’t understand how to leverage the cloud to improve the overall security.
One can argue that the cloud is inherently more secure than on-premises storage, as described in the previous section. However, there are still risks of malware attacks and data breaches. Even though some of them are the cloud vendors’ fault, many are still caused by employees’ errors or internal intentional attacks. These internal threats account for 60% of all data breaches.
Solution:
To mitigate healthcare cloud computing security risks, organizations should opt for a vendor that offers a regular offline backup option to recover lost data instead of paying ransom. Also, medical facilities are advised to look into encryption options. With strong encryption methods, even if the data is breached, it won’t be readable.
It’s also necessary to provide cybersecurity training to employees. Many errors can be avoided if healthcare providers improve their security hygiene. Use cybersecurity-based assessment when choosing contractors, third-party vendors, and other external collaborators.
