In this article, we will explore cloud computing, the services it offers, different deployment models, the benefits of cloud computing, and how organizations are using it.
Understanding Cloud Computing and How It Works
Cloud computing enables businesses to access technology resources, such as servers and databases, without owning them physically. Instead, these resources are rented online, making it easier and more cost‑effective to leverage advanced tools without heavy infrastructure investments.
According to Danielle (2025), Cloud computing refers to using the internet to access computing services, such as servers, storage, databases, software, and data analysis tools, instead of buying and maintaining physical equipment in your business premises. It allows businesses to rent technology resources whenever they need them. This model replaces the traditional approach of maintaining costly in-house infrastructure with a more flexible, scalable, and cost-effective solution.
At its core, cloud computing is built on the idea of sharing computing power, software, and data storage over the internet. Instead of businesses owning their own servers, companies and individuals pay to access a shared pool of virtual resources, such as processing power, storage, and networking, hosted in remote data centers managed by cloud providers.
Cloud computing connects users to a platform through the internet, where they can “rent” the computing services they need. A central system manages the communication between user devices and the cloud’s servers, ensuring smooth data exchange. Additionally, cloud computing has built-in security and privacy features that help protect sensitive information throughout the process, ensuring that business-sensitive data cannot be accessed without authorization.
The cloud computing system is not the same for all businesses, as each has different needs and strengths. Cloud computing offers flexibility, allowing you to customize solutions to your business’s needs. This adaptability enables enterprises to respond more quickly to market shifts and operate with greater flexibility.
Cloud Computing Service Models
Cloud computing service models describe the different layers of services that cloud providers offer to your business; hence, this determines how much control and responsibility you maintain over their systems. By understanding these options, your business can choose the approach that best supports your needs, simplifies operations, and accelerates innovation in the cloud. The following are the models as per Justine (2025)
a. Infrastructure as a Service (IaaS)
IaaS provides the basic building blocks of cloud computing, enabling users to access virtualized computing resources over the internet. With this, your business does not need to manage physical hardware for servers, storage, or networking, as it can easily access them through the infrastructure-as-a-service model of cloud computing. For instance, Amazon Web Services, a cloud computing and web hosting company in Kenya, provides businesses with flexible online infrastructure services, including servers, storage, and databases.
b. Platform as a Service (PaaS)
PaaS offers a complete development environment where developers can build, deploy, and manage applications without managing the underlying infrastructure. Businesses that develop Softwares mainly use this cloud computing service. With platform-as-a-service, they can focus on coding while the platform handles servers, operating systems, and databases.
c. Software as a Service (SaaS)
SaaS delivers fully managed software applications over the Internet, usually via subscription. Users can access the software through a web browser, eliminating the need for local installations. Popular SaaS applications include Google Workspace, Salesforce, Slack, Zoom, and Dropbox.

Cloud Computing Deployment Models
Cloud computing deployment models are how cloud services are set up, hosted, and managed. This determines the level of access and control organizations have over the computing resources. Understanding these options is essential because each model comes with unique advantages and trade-offs. By choosing the model that best aligns with their needs, businesses can optimize their operations and support future growth. A study done by Lucy (2025) highlights the following cloud computing models.
a) Public Cloud
This is a cloud environment accessible to anyone over the internet. In this model, computing resources such as storage, applications, and processing power are shared among many users, which makes it one of the most common and affordable cloud deployment options.
All resources in a public cloud are hosted in the provider’s own data centers. Businesses simply connect to these services as needed, without having to manage any physical hardware. Public cloud platforms can handle large numbers of requests and offer almost unlimited resources, making them ideal for organizations that need to scale quickly and cost-effectively.
b) Private Cloud
This type of cloud environment is dedicated to a single organization. Unlike the public cloud, where hardware and resources are shared with others, the private cloud is reserved exclusively for one user or company. This setup offers greater control, security, and customization, making it ideal for businesses with strict data protection and regulatory requirements.
The key difference between public and private clouds lies in how the underlying hardware is managed. In a private cloud, the infrastructure can be hosted on-site within the company or in a secure, dedicated space managed by a cloud provider. Because it is used by only one organization, the private cloud is sometimes called an “internal cloud,” allowing teams to access systems and services securely from within the company or across multiple locations.
c) Hybrid Cloud
A hybrid cloud combines public and private cloud environments, enabling a company to use its on-premises systems while leveraging public cloud services. These two environments are connected and function as a single system, making this model especially useful for organizations seeking a gradual, flexible transition to the cloud.
Many businesses choose a hybrid cloud because security and compliance requirements prevent them from moving all their data to the public cloud. With this model, sensitive information can remain in private, on-premises systems, while less sensitive workloads and applications run in the public cloud. This approach ensures strong security and control, while also delivering the scalability and cost benefits of public cloud services.
d) Community Cloud
A community cloud is a shared cloud environment designed for several organizations that have similar needs, standards, or regulatory requirements. Instead of each organization building its own private cloud, they use a common platform where resources, services, and infrastructure are shared among members of the same community. The participating organizations, a third-party provider, or both can manage this model.
The key benefit of a community cloud is that it supports organizations with shared goals, such as healthcare providers, financial institutions, and government agencies, by enabling them to collaborate securely while meeting industry-specific compliance standards. It offers a balance of shared costs and specialized control, making it a practical option for groups with similar business or regulatory requirements.
