What is a Cloud Deployment Model?

Cloud deployment models refer to the types of cloud environments designed to suit varying business requirements. From public clouds offering cost-effectiveness to private clouds ensuring enhanced security, the landscape encompasses diverse models, each with its unique features and benefits.

Types Of Cloud Deployment Model

Cloud deployment models categorize how cloud services are hosted and accessed. There are four types:

Public Cloud: Services accessible to the public via the Internet. Shared resources are cost-effective and scalable.
Private Cloud: Dedicated resources for a single organization. Offers greater control, security, and customization.
Hybrid Cloud: Integrates both public and private clouds, enabling data and application sharing. Offers flexibility and scalability.
Community Cloud: Shared infrastructure among organizations with similar needs or compliance requirements. Promotes collaboration and resource sharing.

Each model has distinct advantages, making them suitable for various business needs and preferences.

Public Cloud Model

Among the most prevalent models, the public cloud offers services and infrastructure to multiple organizations over the Internet. It’s cost-effective, scalable, and requires no on-premises hardware.

Public clouds are owned and operated by third-party providers, delivering computing resources like servers and storage to users on a pay-per-usage basis.

Key Attributes of Public Cloud

Here are the key attributes of the Private Cloud Model:
