Technology is constantly evolving. In recent years, no technological advancement has had as much impact as cloud computing. Cloud computing offers the ability to use IT resources in a flexible, scalable, and cost-effective way. Choosing the right cloud model is critical to the success of your organization. In this blog post, together with TTNL’s CTO Derk-Jan Boon, we will delve into the differences between public, private, and hybrid cloud models. We will also provide insights to help you make an informed decision.
What is Cloud Computing?
Before we dive into the differences between types of clouds, such as private cloud, public cloud, and hybrid cloud environments, it’s important to understand what cloud computing generally entails. Cloud computing refers to delivering IT services over the internet. Examples include storage, analytics, databases, and more. You can use external data centers that offer these services, meaning you don’t need to manage hardware and software locally.
The importance of cloud solutions cannot be overstated. They allow you to scale quickly and reduce costs while giving you access to advanced technologies that would otherwise be difficult to implement. Cloud computing has transformed the way we do business and continues to evolve.
Public Cloud: What Is It and Who Is It For?
The public cloud is a cloud environment provided by external cloud service providers. Think of Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure. You don’t have physical servers in your own data center. In the public cloud, countless companies share the same infrastructure and resources. Some characteristics of the public cloud are:
- Scalability
You can easily scale up or down resources based on your needs. This allows you to respond flexibly to changes in demand. - Affordability
The public cloud usually does not require large upfront investments in hardware. Instead, you only pay for what you use, resulting in lower costs. - Accessibility
The public cloud is accessible from anywhere via the internet, making it easy for teams to work remotely.
While the public cloud offers many benefits, there are also drawbacks to consider, such as security and privacy concerns over sensitive information.
Additionally, I see a role for the public cloud in off-site backups or as a third copy and recovery site.”

Private Cloud: An Exclusive Option
A private cloud is a cloud environment specifically managed for one single company. Unlike the public cloud, where resources are shared, the private cloud provides an exclusive environment. Some advantages of a private cloud are:
- Enhanced Security
Since you use the infrastructure exclusively, you can tailor security to your specific standards. - Customization
You have full control over a private cloud, allowing you to customize IT resources according to your requirements. - Compliance
In highly regulated sectors, a private cloud can help meet strict requirements. Examples include industries like healthcare and finance.
The main downside of a private cloud, however, is the higher cost, as the management and maintenance of the hardware are your responsibility.
Hybrid Cloud: The Best of Both Worlds?
A hybrid cloud solution combines elements of the public cloud and the private cloud. It allows you to move workloads and data between both environments, offering various strategic advantages, such as:
- Flexibility
You can use the infrastructure exclusively while adjusting security to your specific standards. - Cost Optimization
You can save costs by placing certain workloads in the public cloud. - Redundancy
If you choose a hybrid environment, you must consider factors such as data integration and security. Managing the complexity of two different cloud environments is also essential.
“In the hybrid cloud, we distinguish between three types of customers. The first group has everything on-premise and asks us to handle the management. Others have production at their own site and also use our platform for disaster recovery. Finally, there are customers who fully use our platform and want to be completely relieved of all worries.”

Which Model Is Best for Your Business?
To determine which type of cloud is best for your company, it’s helpful to compare them based on key differences:
- Cost
The public cloud can be cost-effective due to the pay-as-you-go approach. A private cloud, on the other hand, requires higher initial investments. A hybrid cloud can offer cost optimization by distributing workloads. - Flexibility
The public cloud provides immediate scalability. The private cloud offers more customization. The hybrid cloud, however, offers flexibility by combining both approaches. - Security
The private cloud provides superior security and control over data. While the public cloud offers advanced security measures, it operates with shared infrastructure. With the hybrid cloud, you need to balance security and flexibility. - Scalability
The public cloud is easy to scale. The scalability of a private cloud, however, is more limited. The hybrid cloud offers scalability based on needs.
The right cloud model for your business depends on your specific needs and budget. You should also consider the desired services, such as the use of artificial intelligence. It might even make sense to use different models for different workloads.
Private Cloud vs. Public Cloud vs. Hybrid Cloud: Making the Choice
Choosing the right cloud model is crucial to the success of your business. Whether you opt for a public, private, or hybrid cloud, each approach has its own unique advantages and challenges.
Make an informed choice by considering your needs and goals. Engaging professional cloud service providers, such as TTNL, can simplify the decision. TTNL also helps with cloud migration and optimization and offers various cloud-managed services.
Boon concludes with perhaps his most important tip: “Think carefully about your exit strategy. As I mentioned earlier, retrieving data from the cloud often turns out to be very difficult.
