In 2024, 94% of UK enterprises are utilising some form of cloud service, underscoring its growing importance across various industries. 

From manufacturing and finance to education, professional services, and non-profits, understanding the cloud is critical for staying competitive and driving long-term success. In this blog, we’ll explore the fundamentals of cloud computing, its core service models and deployment options, and how it helps organisations overcome key challenges in today’s business environment.

What is Cloud Computing?

Cloud computing refers to the delivery of computing services, including storage, processing power, databases, networking, and software, over the internet. Rather than relying on local servers or personal computers, cloud computing enables businesses to access resources on demand from third-party providers. 

The cloud computing sector is rapidly growing, with a turnover of £29.8 billion and £1.2 billion in investment, expanding at 22.1% annually. This growth supports its versatile application across industries, helping companies modernise legacy systems, streamline operations, and securely manage data.

• Business Benefits:
  • Eliminates the need for expensive hardware and on-site infrastructure
  • Offers a cost-efficient, scalable, and flexible solution
  • Reduces capital expenditure and IT maintenance burden
• Industry Applications:
  • Used across a wide range of industries
  • Helps modernise legacy systems
  • Supports workflow integration and secure data management

Traditional IT Setups vs. Cloud Computing

Traditional IT setups and cloud computing represent two different approaches to managing and delivering technology services. The table below highlights the key differences between these models in terms of cost, flexibility, and operational efficiency.

Aspect	Traditional IT Setups	Cloud Computing
Infrastructure	Requires on-site servers and hardware with high upfront costs.	Uses remote data centres with no need for local hardware.
Scalability	Scaling requires purchasing and installing new equipment.	Instantly scalable based on demand.
Accessibility	Access is limited to physical location or VPN setups.	Accessible from anywhere with an internet connection.
Maintenance & Updates	IT staff must manage hardware, updates, and backups manually.	Managed by cloud providers with automated updates and backups.
Cost Model	Capital-intensive with ongoing maintenance costs.	Pay-as-you-go model reduces upfront costs and allows better cost control.

Key Characteristics of Cloud Computing

Cloud computing has several defining characteristics that make it an attractive choice for businesses:

1. On-Demand Self-Service

Cloud computing allows users to provision computing resources such as server time and network storage automatically and on demand, without needing to contact the service provider. Customers can use a web-based self-service portal to access their cloud accounts, monitor usage, and easily add or remove services as needed.

2. Broad Network Access

Cloud services can be accessed over the internet or a network from a wide range of devices, including smartphones, tablets, laptops, and desktop computers. Public clouds operate over the internet, while private clouds use internal networks such as local area networks (LANs). The performance of these services is heavily influenced by latency and bandwidth, which impact the speed, responsiveness, and overall quality of the user experience.

3. Rapid Elasticity

Cloud services offer rapid elasticity, allowing resources to be provisioned and released as needed, often automatically. This enables customers to scale up or down quickly based on demand. The available resources for provisioning are virtually unlimited, and users can access them at any time in any quantity. Cloud usage, capacity, and cost can be adjusted without the need for additional contracts or fees. Instead of purchasing physical hardware, customers can rely on the cloud provider’s computing resources.

4. Measured Service

Cloud systems use metering capabilities to track and optimise resource usage at a level suitable for each type of service. Services such as storage, processing, bandwidth, and user access can be measured and billed based on actual consumption. This pay-as-you-go model ensures customers only pay for what they use. Monitoring, controlling, and reporting resource usage helps create a transparent and efficient experience for both service providers and consumers.

5. Resource Pooling

Resource pooling enables multiple customers to share physical and virtual resources through a multi-tenant model. In this setup, resources are dynamically assigned and reassigned based on demand. Multi-tenancy allows users to share infrastructure or applications while maintaining privacy and security. While customers may not know the precise location of their resources, they can often choose a general location, such as a specific country, region, or data center. Commonly pooled resources include memory, processing power, and bandwidth.

Types of Cloud Computing Service Models

Cloud computing services are typically divided into five main models, each offering a distinct level of control and responsibility.
