Types of Cloud Computing (Public, Private, Hybrid)

Cloud computing can be categorized into different types based on deployment models. The three most common models are public cloud, private cloud, and hybrid cloud:

1.Public Cloud:

• In a public cloud model, cloud services are provided over the Internet by third-party vendors (e.g., AWS, Microsoft Azure, Google Cloud). These services are available to the general public, and businesses share the infrastructure with other tenants.
• Advantages: Cost-efficient, scalable, and has no need for infrastructure management
• Disadvantages:: Less control over data security and privacy, shared resources.
2.Private Cloud:
• A private cloud is a cloud environment used exclusively by a single organization. It can be hosted on-premises or by a third-party provider but is not shared with other businesses.
• Advantages: Greater control over security, performance, and data privacy.
• Disadvantages: Higher costs for setup and maintenance, less scalability compared to public cloud.
3.Hybrid Cloud:
• Hybrid cloud combines public and private clouds, allowing businesses to move workloads between them based on their needs. This provides flexibility and optimization of existing infrastructure, with the ability to leverage the public cloud for non-sensitive workloads while keeping critical applications and data in a private cloud.
• Advantages: Flexibility, scalability, and control over sensitive data.
• Disadvantages: Complexity in management and integration between cloud environments
