Cloud technology, also known as cloud computing, refers to the delivery of computing services over the internet. It involves the provision of on-demand access to a shared pool of computing resources, including networks, servers, storage, applications, and services. Key characteristics and components of cloud technology include: 1- On-Demand Self-Service: Users can independently provision computing resources, such as virtual machines, storage, and applications, without requiring human intervention from the cloud service provider. 2- Broad Network Access: Cloud services are accessible over the internet from various devices, including desktop computers, laptops, tablets, and smartphones, enabling users to access their data and applications from anywhere with an internet connection. 3- Resource Pooling: Computing resources, such as processing power, storage, and bandwidth, are shared among multiple users or applications. This allows for efficient utilization and optimization of resources, resulting in cost savings. 4- Rapid Elasticity: Cloud resources can be rapidly scaled up or down based on demand. Users can easily increase or decrease their computing resources to accommodate changes in workload or user requirements. 5- Measured Service: Cloud service usage is monitored, controlled, and billed based on specific metrics, such as resource consumption, storage usage, or the number of users. This pay-as-you-go model provides cost transparency and flexibility.
