OpenStack
OpenStack is an open-source cloud computing platform that provides infrastructure-as-a-service (IaaS) for building and managing public and private clouds. It consists of a set of modular components that handle compute, storage, networking, and other cloud services, allowing organizations to deploy and scale virtual machines and other resources on-demand. It is widely used by enterprises, service providers, and research institutions to create flexible and scalable cloud environments.
Developers should learn OpenStack when working in cloud infrastructure, DevOps, or system administration roles that require managing large-scale virtualized environments, such as in private cloud deployments, hybrid cloud setups, or telecommunications networks. It is particularly valuable for building custom cloud solutions, automating resource provisioning, and integrating with other open-source tools, as it offers control over hardware and avoids vendor lock-in compared to proprietary cloud services.
