OpenStack is an open-source cloud computing platform that consists of several main components, each responsible for different aspects of cloud management and operation. The primary components include:
Nova: This is the compute service that manages the lifecycle of virtual machines. It handles the creation, scheduling, and termination of VMs across a cluster of physical servers.
Swift: The object storage service that allows users to store and retrieve files in a scalable, distributed manner. It's designed for high durability and high availability.
Cinder: Provides block storage services, allowing users to create and manage volumes that can be attached to VMs for additional storage capacity.
Neutron: Manages the networking aspects of the cloud, providing both fixed and dynamic networking capabilities. It allows for the creation of virtual networks, including the allocation of IP addresses and the setup of firewalls.
Keystone: The identity service that provides authentication, authorization, and catalog services for all other OpenStack services. It ensures that users can securely access the resources they are authorized to use.
Glance: Offers image services, enabling the storage, retrieval, and management of disk images and container images used to boot VMs.
Horizon: The dashboard that provides a web-based user interface to interact with OpenStack services. It simplifies the management of cloud resources for administrators and users.
For example, in a typical OpenStack deployment, Nova would handle the creation of virtual machines, while Cinder would manage the storage volumes attached to these VMs. Swift could be used to store backups of these volumes, and Neutron would manage the network connections between the VMs and the storage.
