Study Notes

Cloud computing involves delivering IT services over the internet, offering new technologies and ways of working compared to traditional on-premises setups.
Companies are increasingly moving their IT systems to the cloud, with the majority expected to be cloud-based in the future.
Cloud computing offers different types of cloud deployments: personal cloud for individuals, public cloud for enterprise services over the internet (e.g., Microsoft Azure), private cloud exclusively used by a single organization, and hybrid clouds combining public and private clouds.
Cloud services are classified based on the service they offer: Infrastructure as a Service (IaaS) provides basic cloud computing services like servers and storage (e.g., Microsoft OneDrive for Business), while Platform as a Service (PaaS) offers a software platform for developers.
Transitioning to cloud-based systems requires learning new cloud-based infrastructure and management skills, as well as maintaining skills to keep up with regular cloud service updates.
