What are the Types of Cloud Computing Models and Technical Basics?

There exist three principal models of cloud computing: public cloud, private cloud, and hybrid cloud. Each of these models has its own technical underpinnings, which we shall delve into below:

Public Cloud:

A public cloud is a form of cloud computing model in which the infrastructure and services are owned and managed by a third-party cloud service provider. The provider grants access to computing resources, such as servers and storage, to customers over the internet. The provider manages infrastructure, security, and maintenance, whilst customers pay for their usage.

Public clouds are built on shared resources that are owned and operated by a third-party cloud provider. These clouds are accessible over the internet and offer on-demand services, including storage, computing power, and applications. The provider is responsible for managing the infrastructure and ensuring that resources are available to all users.

The technical basics of public cloud computing model are multifaceted and include:

Multi-tenancy: Public clouds are designed to sustain the needs of multiple tenants or customers who share computing resources and infrastructure, promoting efficiency.
Elasticity: Public clouds are designed to scale up or down quickly, based on the demand for computing resources, allowing for efficient resource allocation.
Pay-per-use: Customers are only charged for the computing resources they use, resulting in a cost-effective solution to computational needs.
Self-service: Customers have the capability to provision computing resources and services on-demand via a web portal or API, enhancing convenience.
Standardization: Public clouds commonly utilize industry-standard technology and protocols to promote compatibility and interoperability between different systems and services.

Private Cloud:

A private cloud is a cloud computing model in which the infrastructure and services are dedicated to a single organization. The organization manages the infrastructure and provides computing resources to its users or customers. Private clouds are built on dedicated infrastructure owned and operated by the organization.

These clouds offer more control and security, as the infrastructure is not shared with other users. Private clouds are typically accessed through a virtual private network (VPN) and can be located on-premise or in a third-party data center.

The technical basics of private cloud computing model are similarly complex and include:

Single-tenancy: Private clouds are designed to cater to the needs of a single tenant or organization, providing complete control over infrastructure and resources.
Customization: Private clouds are highly customizable to meet the specific needs and requirements of the organization, promoting specificity.
Security: Private clouds provide better security than public clouds, as the organization has complete control over access to the infrastructure and resources, ensuring confidentiality.
Cost: Private clouds may be more expensive to set up and maintain than public clouds, but the specific benefits offered justify the cost.

Hybrid Cloud:

A hybrid cloud is a cloud computing model that combines the use of public and private clouds. In a hybrid cloud, an organization utilizes both public and private clouds for different tasks and workloads.

Hybrid clouds offer the flexibility and scalability of public clouds, along with the security and control of private clouds. They require integration between the two cloud environments, which can be achieved through API connections or other means.

The technical basics of hybrid cloud computing model are diverse and include:

Integration: Hybrid clouds are designed to seamlessly integrate public and private cloud services, providing a unified experience.
Flexibility: Hybrid clouds provide flexibility in terms of which workloads are run in which cloud, based on their requirements, promoting efficiency and resource allocation.
Cost: Hybrid clouds can provide cost savings by allowing an organization to use public clouds for less sensitive workloads, while keeping sensitive data and workloads in the private cloud, reducing costs.
Complexity: Hybrid clouds may be more complex to manage than public or private clouds, as they require integration and coordination between multiple cloud environments, resulting in increased complexity.   

Cloud Computing and its role in the Pharmaceutical Industry: 

Cloud computing has revolutionized the way pharmaceutical companies store and process data, especially in a GxP environment. It offers several benefits, including improved data security, reduced costs, and increased scalability.
