What is OpenStack?

OpenStack is an open-source platform offering a collection of software modules, called projects, that work together to create and manage cloud infrastructure. It is one of the many open-source technologies that helps IT teams create and manage cloud workloads. It is often seen as an alternative to public cloud platforms like AWS and Microsoft Azure, especially for organizations that prefer to build and manage their own cloud environments.

OpenStack is typically provided as an Infrastructure as a Service (IaaS) platform, giving users access to fundamental computing resources such as virtual machines, storage, and networking.

Role of Virtualization in OpenStack

To run multiple applications and operating systems on the same physical hardware, organizations often use virtualization. Virtualization enables multiple virtual machines to share a single physical server through tools known as a hypervisor. It also abstracts computing resources from the underlying hardware, making resource allocation more flexible and efficient.

OpenStack is built on top of this virtualization layer. By managing virtualized compute, storage, and networking resources, OpenStack acts as a cloud operating system that enables organizations to deliver infrastructure resources on demand.
