what is Openstack:
OpenStack’s structure consists of numerous standalone services, strategically orchestrated to collaborate and deliver a comprehensive cloud computing solution. Its architecture adopts a modular concept, permitting the use of each element individually or in tandem with others to cater to distinct requirements Here are the main components of the OpenStack architecture:
“OpenStack Architecture Overview:
Compute (Nova): Nova stands at the core of OpenStack, serving as the backbone for on-demand creation and management of virtual machines (VMs). It encompasses an API that handles VM lifecycle management, from provisioning to scheduling and termination.
Networking (Neutron): Neutron takes charge of network connectivity and services for VMs, overseeing the network topology in OpenStack deployments. This includes support for virtual switches, routers, firewalls, and other essential networking elements.
Storage (Swift, Cinder, Manila): OpenStack offers a range of storage services, including Swift, an object storage system built for scalability and resilience, and Cinder, a block storage service for persistent VM storage. Manila contributes a shared file system service, facilitating access to shared file system for multiple VMs.
Identity (Keystone): Keystone delivers authentication and authorization services within OpenStack. It accommodates various identity backends, including LDAP, SQL, and Active Directory, and can be integrated with other authentication systems like OAuth and SAML.
Dashboard (Horizon): Horizon delivers a web-based interface for the management of OpenStack services. It features dashboards tailored to compute, networking, storage, and other vital OpenStack components.
Orchestration (Heat): Heat introduces an orchestration engine to OpenStack, allowing users to define templates for infrastructure deployment and management. This includes support for advanced features like auto-scaling and rolling updates.
Telemetry (Ceilometer): Ceilometer steps in to provide monitoring and metering services for OpenStack. It can collect and analyze metrics for compute, storage, and networking services, while also offering billing and chargeback capabilities.
These components collaborate harmoniously to create a comprehensive cloud computing platform suitable for a variety of use cases, whether private, public, or hybrid clouds. The architecture offers flexibility, allowing users to select and configure the necessary components to meet their specific requirements.
OpenStack is constructed from a collection of independent services meticulously designed to seamlessly integrate and provide a comprehensive cloud computing platform Here are some of the main OpenStack services:
Nova (Compute Service): Nova forms the core of OpenStack, enabling the dynamic creation and management of on-demand virtual machines (VMs).
Neutron (Networking Service): Neutron orchestrates network connectivity and services for VMs while overseeing the network architecture in OpenStack environments.
Cinder (Block Storage Service): Cinder serves as the magical block storage service, offering persistent storage solutions for VMs. It provides access to volumes that can be attached to VMs, serving as bootable devices or data repositories.
Swift (Object Storage Service): Swift is the sorcerer of object storage, designed for scalability and unshakable durability. It offers a scalable, redundant repository for unstructured data like images, videos, and documents.
Keystone (Identity Service): Keystone acts as the sorcerer of identity, granting authentication and authorization within OpenStack. It supports various identity sources, including LDAP, SQL, and Active Directory, with the ability to integrate with authentication systems like OAuth and SAML.
Horizon (Dashboard Service): Horizon enchants with its web-based interface, allowing enchanters to manage OpenStack services with ease.
Heat (Orchestration Service): Heat conducts orchestration in the OpenStack realm, enabling users to script infrastructure deployment and management using templates.
Glance (Image Service): Glance is the conjurer of image storage, providing a repository for storing and enchanting virtual machine images in various formats, including RAW, VHD, and VMDK.
Ceilometer (Telemetry Service): Ceilometer practices the art of monitoring and metering services within OpenStack.
These components combine their magical powers to craft a comprehensive cloud computing platform, suitable for enchanting private, public, and hybrid cloud scenarios. Their modular and flexible nature allows conjurers to select the components they need and conjure them to their specifications.
