Cloud Service
A cloud service refers to the delivery of computing resources—such as storage, processing power, databases, software applications, and networking—over the internet on a pay-as-you-go basis. These services eliminate the need for users to invest in or maintain physical hardware and infrastructure.
Cloud services are offered through remote data centres managed by cloud providers. They are typically divided into three main models:
- IaaS (Infrastructure as a Service): Virtualised hardware resources, such as servers and storage (e.g. Amazon EC2).
- PaaS (Platform as a Service): Development and deployment platforms (e.g. Google App Engine).
- SaaS (Software as a Service): Ready-to-use applications accessible via browser or API (e.g. Microsoft 365, Salesforce).
Cloud environments can be public, private, or hybrid depending on the organisation’s security, compliance, and control requirements.
Benefits
- Scalability: Resources can be scaled up or down based on demand.
- Cost-efficiency: Users only pay for what they use.
- Accessibility: Services are available globally via the internet.
- Flexibility and automation: Easily integrated into development pipelines and business operations.
Cloud services form the backbone of modern digital ecosystems, powering everything from mobile applications and IoT solutions to enterprise software and artificial intelligence workflows.
