Every modern business uses cloud computing, and for good reason: faster communications and collaboration, secure file sharing, delivering personalised customer services – the benefits are numerous.
But what exactly is cloud computing? It’s possible you have been utilising the cloud without even realising. Document management, file storage, online chat tools – many digital solutions operate on the cloud or rely on cloud infrastructure.
Whether you are new to cloud computing or looking to deepen your understanding, this guide will provide valuable insights.
What is Cloud Computing?
Cloud computing involves delivering a variety of computing services over the internet, including servers, storage, databases, networking, software, and more. Instead of relying on local hardware and infrastructure, businesses can access and store their data and applications on remote servers hosted by cloud service providers.
With all the different types of cloud computing infrastructure, organisations can scale their resources up or down based on demand, pay only for what they use, and eliminate the need for significant upfront investments in physical IT infrastructure.
Additionally, cloud computing enhances collaboration by allowing employees to access applications and data from anywhere, ensuring seamless teamwork and productivity. Overall, the cloud represents a shift towards more efficient, adaptable, and cost-effective IT solutions.

3 Main Cloud Services: IaaS, PaaS, SaaS
The three main types of cloud services are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each offers unique benefits and use cases, catering to different business needs.
Infrastructure as a Service (IaaS)
IaaS provides virtualised computing resources over the internet, allowing businesses to rent servers, storage, and networking infrastructure on a pay-as-you-go basis. This model offers tremendous flexibility, enabling companies to scale their resources up or down as needed without the burden of maintaining physical hardware.
Examples:
- Amazon Web Services (AWS): Offers a wide range of cloud infrastructure services, including computing power, storage, and databases.
- Microsoft Azure: Provides scalable cloud computing resources and services for building, testing, and managing applications and services.
- Google Cloud Platform: Delivers cloud infrastructure solutions for compute, data storage, and networking, along with machine learning and data analytics capabilities.
Platform as a Service (PaaS)
PaaS offers a platform for developers to build, run, and manage applications without dealing with the underlying infrastructure. PaaS solutions generally include everything needed for application development, such as development tools, middleware, and database management systems, simplifying the development process and reducing the time spent on marketing.
Examples:
- Google App Engine: A fully managed cloud-based platform that allows developers to build and deploy applications using popular programming languages and frameworks.
- Microsoft Azure App Services: Enables the creation and deployment of web and mobile applications, providing built-in scalability and security features.
Software as a Service (SaaS)
SaaS software applications are delivered over the internet on a subscription basis. These applications are hosted and maintained by the service provider, eliminating the need for installations, maintenance, and updates on local devices. SaaS is ideal for businesses seeking to streamline operations with minimal IT management overhead.
Examples:
- Google Workspace: A suite of productivity and collaboration tools, including Gmail, Google Drive, and Google Docs, designed for seamless team collaboration.
- Microsoft 365: A collection of productivity applications and services, including Word, Excel, and Teams, that enhance workplace productivity and communication.
3 Main Cloud Computing Models
When it comes to cloud computing, choosing the right deployment model is crucial for aligning with your business needs and goals. Here’s a succinct explanation of the differences between private, public, and hybrid clouds.
Private Cloud
A private cloud is dedicated solely to one organisation, providing a high level of control over data, security, and compliance. This type of cloud can be hosted either on-premises within the company’s own data centre or by a third-party provider.
Key Characteristics:
- Enhanced Security: The private cloud offers robust security measures tailored to the organisation’s specific needs, ensuring sensitive data is protected.
- Customisation: Businesses can customise their cloud environment to meet precise requirements, from hardware and storage to networking configurations.
- Compliance: It is easier to comply with regulatory requirements as the infrastructure can be designed to meet specific compliance standards.
Ideal for: Organisations with stringent security needs, regulatory requirements, and the necessity for highly customised infrastructure.
Public Cloud
A public cloud is operated by a third-party provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform. Resources such as servers and storage are shared among multiple organisations, but data is isolated and remains secure.
Key Characteristics:
- Cost-Efficiency: Utilises a pay-as-you-go model, eliminating the need for significant capital expenditures on IT infrastructure. This model allows businesses to only pay for the resources they consume.
- Scalability: Easily scalable to accommodate varying workloads, making it simple to handle unexpected spikes in demand without investing in additional physical hardware.
- Accessibility: Services and applications hosted on a public cloud can be accessed from anywhere with an internet connection, facilitating remote work and global collaboration.
Ideal for: Startups, small to medium-sized businesses, and enterprises looking for cost-effective solutions with flexibility and minimal management overhead.
Hybrid Cloud
A hybrid cloud integrates private and public cloud environments, allowing data and applications to be shared between them. This model provides greater flexibility and optimises the existing infrastructure while leveraging the benefits of both private and public clouds.
Key Characteristics:
- Flexibility: Enables businesses to move workloads between private and public clouds as their needs change, providing a dynamic and adaptable IT environment.
- Optimisation: Balances cost, performance, and security by allowing businesses to run sensitive, mission-critical workloads in a private cloud while utilising the public cloud for less sensitive operations.
- Business Continuity: Offers enhanced disaster recovery and backup options by distributing workloads and data across both private and public clouds, ensuring minimal downtime and data loss.
Ideal for: Organisations that require a mix of on-premises infrastructure for sensitive data and applications, along with the scalability and cost benefits of the public cloud for other workloads.
