This rapid growth highlights the increasing significance and potential of cloud deployment for businesses. The following sections will introduce the four common cloud computing models, helping businesses identify the most suitable option for their needs.
What are the 4 Types of Cloud Computing?
- Public Cloud – A cloud environment managed by third-party providers, offering cost-effective scalability and accessibility over the Internet.
- Private Cloud – A dedicated cloud infrastructure for a single organization, providing enhanced security, control, and compliance.
- Hybrid Cloud – A combination of public and private clouds, allowing businesses to optimize performance, security, and cost efficiency.
- Self-Hosted Deployment – A deployment approach where organizations run software within their own controlled environment using tools like SDKs, APIs, or Docker.
What is Public Cloud?
Public cloud refers to cloud computing model provided by third-party public cloud providers over the public internet, making them available to anyone who wishes to use or purchase them. These services may be free or sold on-demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume. Major public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
What are the Advantages of Public Cloud?
Cost-Effectiveness
Public cloud operates on a pay-as-you-go model, eliminating the need for significant upfront capital expenditure. This model is particularly beneficial for startups and small to medium-sized businesses looking for cost savings.
Scalability
Public cloud services offer virtually unlimited scalability, allowing businesses to easily adjust resources to meet fluctuating demands without the need for physical infrastructure changes.
Maintenance-Free
The cloud service provider manages all maintenance activities, updates, and security, freeing businesses from the burden of infrastructure management and allowing them to focus on core activities.
What are the Disadvantages of Public Cloud?

What is Self-Hosted Deployment?
Self-hosted deployment refers to installing and operating software within an organization’s own controlled environment, whether on internal infrastructure or a private cloud managed by a third-party provider. While the servers may be externally hosted, the organization retains full control over software configuration, data storage, and access. This deployment model provides a balanced approach between flexibility and control, and is often implemented using technologies like SDKs, APIs, and Docker for seamless integration and data privacy.
For instance, at KDAN, we offer a flexible self-hosted deployment service that allows businesses to integrate our products into their existing IT environments tailored to their preferences and compliance requirements. Our modular architecture supports secure deployment, model training within the client’s environment, and integration with existing internal systems, without the need to rebuild the core product from scratch.
What are the Advantages of Self-Hosted Deployment?
Flexible Control and Integration
Self-hosted deployment provides a high level of control over system configuration, data storage, and software customization. Organizations can deploy the solution in their preferred infrastructure (cloud, hybrid, or local server), maintaining root-level access and full data visibility as needed.
Deployment with Data Privacy in Mind
While the infrastructure may be managed in-house or by a third party, self-hosted deployment allows organizations to monitor the processes closely. For example, at KDAN, the deployment is executed under customer-side supervision to ensure that all sensitive data remains securely within the customer’s environment. When remote access is necessary, customers can choose to grant limited, temporary access with strict permissions.
Compliance Enablement
With data hosted in a controlled environment, companies can more easily comply with local or industry-specific data residency and regulatory standards, such as GDPR or ISO 27001.
What are the Disadvantages of Self-Hosted Deployment?
Initial Setup Complexity
Deploying a self-hosted solution still requires IT planning, infrastructure configuration, and integration efforts.
