In cloud computing environments, the deployment model refers to the arrangement and specific configuration of computing resources, services, and infrastructure. The deployment model defines how these resources are organized, managed, and made accessible to users.
Which deployment model makes most sense for an organization depends on various factors such as data security requirements, customization needs, and the type of the workloads being managed in the cloud. For help on figuring out the adequate deployment model for your organization, scroll down to the chapter “which deployment model should we choose?”. But first, we’ll see which options are currently the most popular ones.
The three most commonly used types of deployment models in cloud computing are public cloud, private cloud, and hybrid cloud. According to a study by AAG IT, a stunning 89% of companies use “multi-cloud solutions”. This means they don’t rely on a single public or private cloud provider but distribute their computing power over multiple cloud vendors.
For those of you that are into numbers, we collected some cloud computing deployment model statistics:
🤷❓ What does private cloud mean? Why do companies choose to combine public clouds with private ones? What are examples for each? In this section, we’ll explain the different cloud deployment models, highlight their (dis-)advantages, give insights into the reasons why a company would choose which model and give examples for each. Let’s get going!
A private cloud is dedicated to a single organization. It can be hosted on-premises (within the organization's own data center) or by a third-party provider. This deployment model focuses on security and offers more control and customization over the infrastructure.
Examples for private could setups: VMware, OpenStack, Amazon Virtual Private Cloud, Google Virtual Private Cloud, etc.Only 4% of organizations rely solely on private cloud(s). But the private cloud still remains a vital part in the cloud infrastructure of most organizations.
Cloud resources and services are owned and operated by a third-party cloud service provider. These resources are made available to the general public or a large industry group and are accessible over the internet.
Examples for public could setups: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP)

The model most organizations opt for: A hybrid cloud combines elements of both public and private clouds, allowing data and applications to be shared between them. This model provides greater flexibility and more deployment options. Organizations can, for example, use the public cloud for scalable tasks and the private cloud for sensitive or critical workloads.While being the choice of 80% of organizations, the hybrid cloud model isn’t a candy shop either. Every deployment model comes with both pros and cons.
Examples for hybrid could setups: A company uses a private cloud for sensitive data and applications, while utilizing a public cloud for additional computing resources during peak demand.
If you’ve paid attention earlier in this article, you’ll be surprised there is a fourth chapter - didn’t we claim there are only three main deployment models? You’re right - we don’t see multi-cloud deployment as a different model per se but rather as an option that combines with all of the mentioned “main” models: private, public and hybrid. It focuses on not putting all the eggs in one basket, using services from multiple (at least two) cloud providers. This is possible in a purely private / purely public cloud setting but of course also in a hybrid cloud environment.Don’t want to place all eggs in one basket: Most companies prefer distributing responsibilities over multiple cloud service providers. This reduces vendor lock-in and general dependency on one single company.
What does multi-cloud deployment look like? There are various multi-cloud deployment scenarios: Organizations may choose different providers for specific tasks or to avoid vendor lock-in. It allows for diversification of resources and can enhance redundancy and resilience. Possible multi-cloud options are:
Sounds a bit complicated? To keep track of all your multi-cloud engagements, it’s highly recommended to use a multi-cloud management platform. Read this article to learn more about what such a platform can bring to your organization: The Benefits of Using a Multi-Cloud Management Platform
⚠️ If you combine public AWS cloud with a private AWS outposts setting, it is considered hybrid cloud (mix of public and private) but can’t be regarded as “multi-cloud”, since both services are provided by Amazon Web Services.
As stated in the AAG IT report, 89% of companies use this “multiple-provider” model and rely on multiple cloud vendors at the same time. It allows them to pick and blend the top features from different cloud providers to match their applications, workloads, and business needs. Speaking of “needs” - after understanding the different options, the natural question that comes up is “OK, so what is the best model for us?”
We both know there’s no easy answer. But before jumping into this decision and comparing offers, there are multiple things you need to do:
Conducting a thorough evaluation of these factors will empower you to make an informed decision that aligns with your organization’s goals and sets the stage for successful cloud adoption.
