Understanding cloud deployment models

Cloud deployment models define how cloud services are provisioned, managed, and delivered to users. They outline the architecture, scalability, and management responsibilities, determining the relationship between the cloud infrastructure and its users. There are several main cloud deployment models, each with distinct characteristics and use cases.

Types of cloud deployment models

Public cloud

• Definition: Shared infrastructure managed by a third-party provider, available to the general public.

• Advantages: Cost-effective, scalable, and maintenance-free.

• Limitations: Potential security and compliance concerns due to shared resources. Learn more about public cloud.

Private cloud

• Definition: Dedicated resources for a single organization, either on-premises or hosted by a third party.

• Advantages: Enhanced security, compliance, and customization. For more details, see private cloud.

• Limitations: High cost and need for in-house expertise for maintenance.

Public cloud example

• Scenario: A start-up leverages AWS to handle website traffic. It gains scalability and reduces costs. Maintenance becomes a non-issue.

Private cloud example

• Scenario: A healthcare provider stores patient data on a private cloud. This ensures compliance with data protection laws. The setup enhances security.

Hybrid cloud example

• Scenario: A retail business uses a hybrid cloud model. It manages high-demand web traffic on a public cloud. Sensitive transaction data remains secured on a private cloud.
