Cloud computing is a technology that allows users to access and manage computing resources (such as servers, storage, databases, and software) over the internet, rather than using local hardware or on-premises infrastructure. This model provides flexibility, scalability, and cost-efficiency by offering resources on-demand and typically on a pay-as-you-go basis.
Some popular cloud services include:
1. **Amazon Web Services (AWS)**: Provides a wide range of cloud services, including computing power, storage, and databases.
2. **Microsoft Azure**: Offers various cloud services such as virtual machines, databases, and AI tools.
3. **Google Cloud Platform (GCP)**: Includes services for computing, storage, data analysis, and machine learning.
4. **Dropbox**: A cloud storage service for file storage and sharing.
5. **Salesforce**: A cloud-based CRM (Customer Relationship Management) service that helps manage customer interactions and data.
These services enable users to scale resources up or down as needed, enhancing efficiency and flexibility in managing IT infrastructure and applications.
