Basic Cloud ☁ Deployment Models
Public Cloud ☁️: In a public cloud model, cloud services are provided by third-party service providers over the internet. These services are available to the public, and multiple organizations or individuals can share the same infrastructure. The infrastructure, applications, and services are owned and managed by the cloud provider, and users access them via the internet. Public cloud deployments offer scalability, cost-effectiveness, and ease of use.
Private Cloud 🏢: A private cloud model is dedicated to a single organization. It provides similar benefits to a public cloud, such as scalability and self-service capabilities, but the infrastructure is exclusive to the organization. The organization may choose to host the private cloud on-premises or have it hosted by a third-party service provider. Private clouds are suitable for organizations that have specific security, compliance, or performance requirements.
Hybrid Cloud 🌐: A hybrid cloud model combines elements of both public and private clouds. It involves the integration of on-premises infrastructure or private cloud with public cloud services. Organizations can utilize the public cloud for scalability and flexibility, while maintaining control over sensitive data and critical applications in the private cloud or on-premises. Hybrid cloud deployments offer the ability to leverage the advantages of both models and enable workload portability.
Community Cloud 🤝: A community cloud model is a shared infrastructure and services environment that is built for a specific community of organizations with common interests or requirements. These organizations collaborate to define the cloud infrastructure and policies to meet their collective needs. The community cloud can be managed by the organizations themselves or by a third-party provider. It allows for resource sharing, cost-sharing, and increased control compared to public clouds.
Multi-Cloud 🌍: A multi-cloud model involves the use of multiple public cloud providers or a combination of public and private clouds to meet an organization’s needs. It allows organizations to leverage the strengths and capabilities of different cloud providers, avoiding vendor lock-in and providing redundancy and flexibility. Multi-cloud deployments require managing multiple cloud environments and ensuring compatibility and interoperability between them.
Each deployment model offers distinct advantages and considerations, and organizations choose the model that best aligns with their requirements, budget, security, and compliance needs.
