The Core Differences Between Public and Private Clouds

Cloud computing applications deliver technology over a secure internet connection. Through the cloud, you can manage servers, databases, file storage, software, networking and other computer services. As one of the IT industry’s fastest-growing technologies, cloud computing has numerous developments in store for the future.

A cloud network can come in a public or private deployment model. In 2018, 92% of 
organizations used public cloud, while 75% relied on private cloud networks. But which is the better choice for your organization? Each of these options has unique strengths and uses in healthcare applications. Learn more about private and public clouds in personal, business and healthcare applications.

Public Cloud

People across the world use public cloud services in everyday computing. In a public cloud deployment model, a third party owns and operates the cloud resources and delivers them over the internet. The people who use a public cloud service use the same hardware, network devices and storage with separate accounts. You can find public cloud technology used in:

Email services: Today’s popular email services use cloud servers to store user information such as inbox content and sent emails.

Online applications: Online office applications keep many of their resources on a cloud server to save space in your local storage.

File storage: Cloud file storage systems can hold documents, pictures and other files as a standalone service or part of a larger application.

Uses as Infrastructure

Many companies that offer public cloud services have massive infrastructure systems that manage large amounts of information. Since a public cloud holds data for as much as millions of users, it needs major computing capacity. A large public cloud includes traditional servers and network equipment such as multicore servers and routers. However, these devices operate on a big scale with high-capacity models in large numbers.

Business and Personal Applications

Both people and businesses make use of public cloud services. Since the public cloud comes in so many forms, it suits the needs of a wide range of users. Some businesses use public cloud services for applications that don’t require tight security. Meanwhile, personal users take advantage of public cloud computing’s low costs and accessibility.

Private Cloud

Businesses and organizations use private cloud computing to manage critical information securely. A single organization or business owns a private cloud network exclusively for their computing applications. Multiple people still share the same resources, but on a much smaller and more secure scale. Organizations and businesses use private cloud computing for:

Databases and records: A private cloud can securely store files and documents in a database that users can access from their organization’s devices.

Secure email: Through private cloud storage, an organization can send secure emails that they store on their private cloud servers.

Custom cloud applications: Some organizations develop custom software to access their private cloud applications and improve their workflows.

Infrastructure Applications

The infrastructure for a private cloud network involves many of the same devices as a public cloud network’s infrastructure. Businesses and organizations have a few options for their private cloud. Some organizations own all the equipment involved in managing a private cloud network. However, maintaining this equipment can become difficult for an organization without a large IT department. Organizations that need assistance with their cloud infrastructure can use infrastructure as a service (IaaS). In an IaaS model, a company manages your private cloud infrastructure for you.

Personal and Business Uses

In the majority of cases, businesses and organizations use private cloud computing. Private cloud services have features tailored to the needs of organizations, including security and customization. They also tend to have higher levels of efficiency and data privacy than public platforms.

Combining Connectivity in Cloud Computing Software Programs

Public and private cloud services each have unique benefits that businesses can use. To take advantage of all of these features, some organizations choose a combination of private and public cloud services. A combined solution can increase deployment options and optimize digital operations. However, it may also take extra work from the organization’s IT team. Popular combination cloud deployment models include:

Multi Cloud

Multi clouds involve the use of multiple private and public clouds to manage data and infrastructure. Depending on the organization’s needs, a multi cloud could save money by dedicating some services to more affordable platforms. Keeping the same information on many clouds also provides a backup system in case of data loss. If one of the services in a multi cloud goes down, the user can take advantage of the other clouds at their disposal.

Hybrid Cloud

Hybrid clouds also include multiple cloud services, but the clouds integrate or work side by side. While a multi cloud’s services function separately, a hybrid cloud’s platforms operate together. A hybrid cloud user can move data and applications between private and public clouds as their needs change. For example, some organizations use the public cloud for purposes with lower security needs and keep sensitive data on private clouds. An organization may also have an additional cloud network to use during a spike in demand.

Differences Between Public and Private Cloud Services

Private and public clouds have different applications and upkeep requirements. Consider these differences between the two deployment models:

Server Location

The server location of a cloud can vary based on its status as a private or public platform. When you use a public cloud service, the company will own and manage the servers. Meanwhile, some private cloud services require the user to oversee their servers. Comprehensive private cloud solutions like those from Prelude Services include server management as part of their services.

IT Overhead

Public cloud platforms tend to cost less than private solutions, but they may not have as many robust features. A private cloud network requires an initial investment for installation and deployment, while many public solutions come prepackaged. However, the cost of public cloud services can rise when you have large-scale needs. In industries such as healthcare with strict regulations, you may also have to invest in a private cloud to stay compliant.

Customization

Private cloud services offer many more customization opportunities than public cloud solutions. In a public cloud model, the company that manages the service controls its appearance and features. A private cloud platform enables you to customize your features and user interface to meet your organization’s needs. You can also adapt your private cloud system to changes in your company or industry.

Scalability

Thanks to the nature of cloud computing, both public and private models have high levels of scalability. If your computing needs vary, you might benefit from looking into a hybrid solution to accommodate temporary demand. Many public and private models also let you scale your services as needed when you adjust your service plan.

Maintenance

While public clouds require no maintenance from the user, some private clouds will need it. If you choose a comprehensive private cloud solution, the service company will take care of upkeep for you. However, you might need to take care of it with another type of private service, especially if you build yours in-house.

Using Public and Private Cloud Computing for Healthcare

At Prelude Services, we recommend private cloud deployment over a public model for healthcare organizations. The healthcare industry involves many security regulations to protect patient information, such as HIPAA. We also suggest private cloud computing for these reasons:

Portability: Private cloud services enable you to access your data securely from anywhere with an internet connection. As a result, your staff can manage records across facilities.

Flexibility: Your organization can adapt private cloud services to changing regulations and best practices. This feature means that your private cloud can grow with the industry.

Dedicated servers: A private cloud platform has dedicated servers for your organization. With a standalone infrastructure, you will have better privacy and performance.
