Cloud computing provides computing resources and services over the internet, including hosted infrastructure, data storage, search, and tools for building or coordinating software. This collection brings together names associated with that wider ecosystem: AWS CloudSearch and Step Functions represent cloud-based search and workflow services, while CloudLinux and Docker relate to the systems and technologies used to run applications. Other examples, such as Lightroom CC, connect cloud services with software people use in their everyday work. Together, these subjects show how "cloud" can refer both to the underlying computing infrastructure and to applications and services that rely on networked access, synchronization, or hosted processing.
