Cloud computing delivers computing services—like servers, storage, and software—over the internet. It offers flexibility, scalability, and cost savings for businesses and users.
The three main models are IaaS (infrastructure), PaaS (platform), and SaaS (software). Each offers different levels of control and management for users.
Clouds can be public, private, or hybrid. Public clouds share resources, private clouds are dedicated to one organization, and hybrid clouds mix both for flexibility.
Cloud computing enables on-demand access, broad network access, resource pooling, rapid scalability, and a pay-as-you-go pricing model for efficient resource use.
Data is secured with encryption, access controls, and regular audits. Providers ensure compliance with regulations like GDPR and use redundancy for data protection.
Auto-scaling automatically adjusts computing resources based on demand, ensuring performance and cost efficiency without manual intervention.
APIs let software communicate with cloud services, enabling automation, integration, and easy management of cloud resources and applications
