Cloud computing is a technology that allows access to computing resources via the Internet. Computing resources can be hardware, databases or applications.
Virtualisation technologies allow consolidating almost any number of physical machines with the required CPU, GPU, RAM and storage capacity for a specific task. If necessary, resources can always be quickly scaled up.
Thus, the customer of the service can optimise costs by eliminating the need to purchase and maintain their own equipment.
The development of cloud computing technology has led to the creation of new advanced formats of cloud services that can provide service providers, such as Infrastructure as a Service (IaaS), Platform As a Service (PaaS), Network As a Service (NaaS), Security as a Service (SECaaS), Database as a Service (DBaaS) and many others.
