Cloud Deployment Models

Selecting the most appropriate cloud deployment model is essential to utilize the complete potential of cloud services. Whether you're a small business or a large enterprise, choosing the right cloud model can affect your security, scalability, and operational efficiency.

A cloud deployment model determines where the infrastructure for your deployment exists and who owns & controls that infrastructure. We will discuss its re-known types below:

Public

A public cloud is a type of cloud computing where computing resources like servers and applications are offered over the Internet by third-party providers and shared by multiple organizations and individuals. It’s accessed via the internet with the provider managing and maintaining the infrastructure, while users can access the services through a web browser or API.

Public cloud is accessed by multiple customers at the same time. It is a model in which concurrent access to cloud resources is made available by Cloud Providers by handling authentication & resource division. Hardware resource utilization is optimized such that it maintains Confidentiality, Integrity, and Availability of user’s data.

Advantages: Minimal Investment, No setup cost, No Infrastructure management required, No hardware maintenance, Dynamic Scalability

Disadvantages: Limited Customization, Less Secure

Examples: AWS S3, Azure Virtual Machines, Google App Engine

Private

A private cloud is a cloud computing environment dedicated to a single organization offering exclusive access to computing resources like storage and processing power, without sharing them with other businesses. This allows the organization to have greater control over its data, security, and performance.

It is exactly the opposite of the Public cloud as the name suggests. It is a one-on-one environment for a single user (customer). There is no sharing of your hardware resources with anyone else.

Advantages: Better Customization, Better Control, High Data Security & Privacy

Disadvantages: Costly, Less Scalable

Examples: AWS Outpost, Azure Private Link, Google Virtual Private Cloud

Private Cloud Architecture

Hybrid

A hybrid cloud combines both a private (on-premises) and a public cloud, allowing organizations to leverage the benefits of each environment while managing data and applications between them. This approach is often chosen to meet regulatory requirements, take advantage of on-premises investments, or address low-latency needs.

Advantages: Flexibility & Control, Reduced Cost, Better Security

Disadvantages: Expert Management Required

Community

A community cloud is a cloud computing infrastructure shared by multiple organizations that have common concerns or requirements, such as shared mission, security, policy, or compliance. It's a collaborative environment where resources and services are shared between participating members, offering cost-sharing and compliance benefits.

Advantages: Better security, Cost-effective, Shared resources, collaboration & Data Sharing

Disadvantages: Rigid Customization, Limited Scalability

Multi-Cloud

Multi-cloud is a cloud computing strategy where organizations utilize services from multiple cloud providers, instead of relying on a single provider. This allows them to access a broader range of services, optimize costs, and enhance resilience by distributing workloads across different platforms. It's quite rare that two different clouds would run into error at the same moment. As a result, multi-cloud deployment improves the availability of your cloud services.

Advantages: Best Features Pick from Different Cloud Provider, Reduced Latency, High Availability

Disadvantages: High Expertise required for management, Security Issue due to complex structure
