Cloud computing refers to the delivery of computing services such as servers, storage, databases, networking, software and analytics over the internet instead of relying on local computers or physical infrastructure. It allows businesses and individuals to access technology resources on demand without owning or maintaining expensive hardware.
Cloud computing has transformed the global technology industry by making computing resources scalable, flexible, and cost efficient. Major cloud providers such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform offer services that enable organisations to run applications, store data and process workloads from remote data centres.
Types of cloud computing services
There are three major types of cloud computing services. Infrastructure as a Service (IaaS) provides virtual servers and storage. Platform as a Service (PaaS) offers development environments for applications. Software as a Service (SaaS) delivers software applications over the internet.
Cloud computing plays a major role in artificial intelligence because AI models require massive computing power and storage capacity. Businesses use cloud platforms to train AI systems, deploy applications, and manage data efficiently.
In data centres, cloud computing improves resource utilisation through virtualisation and automation. It also supports remote work, digital transformation, online collaboration, and enterprise scalability.
One of the biggest advantages of cloud computing is flexibility. Companies can quickly scale resources up or down based on demand. It also reduces capital expenditure because organisations pay only for the resources they use.
However, cloud computing also creates challenges related to cybersecurity, data privacy, compliance, and downtime risks. Businesses therefore invest heavily in cloud security and backup infrastructure.
Cloud computing is now considered the foundation of modern digital services and continues to drive innovation across industries worldwide.
