What Is OpenStack And Its Components
OpenStack And Its Components
OpenStack is a free and open-source infrastructure as a service (IaaS) initiative. It is used for creating and managing large groups of virtual and private servers in a data center. It is also used to handle hardware, storage, and networking resources. It can be managed in different ways. It has a graphical user interface (GUI) means users can manage it through web browsers. OpenStack also provides features of a command line you can manage it through CLI. Its RESTfull APIs are also available for users.
OpenStack released under the Apache license. It is written in Python language and supported cross platforms. It is often represented in the media as Linux of the cloud. The main purpose of OpenStack is to provide interoperability between cloud services. Many well-known brands rely on OpenStack to run their business such as BMW, GoDaddy, Wells-Fargo, Time-Warner Cable, PayPal, eBay, Intel, NASA, Yahoo, DreamHost, and many more.
Industries Which Can Gets Benefits From OpenStack
OpenStack supported almost all types of industries. Different types of industries get benefits from these open-source applications and modify this product according to their needs. Let's see some of these industries which can get benefits.
- Information Technology
Components Of OpenStack
It has a modular architecture, it has been build over different parts. Since it is an open-source solution therefore its users can expand its functionality by adding different components to accomplish their specific needs. Let's see some of its components.
Nova is an important part of infrastructure-as-a-service (IaaS) and used as a cloud computing fabric controller. It is specially designed in such a way to automate pools of computer resources and can work with visualization.
It provides catalog, repository, discovery, registration, and delivery services for virtual disk images. It is used to store unlimited backups.
It provides a scalable storage system. It is supported object storage and files. Swift with OpenStack software takes responsibility of data replication and integrity across the cluster.
This component of OpenStack provides a graphical user interface (GUI) for both administrators and users to access, provision, and automate cloud-based resources.
It is a storage component. It provides block-level storage devices for use with OpenStack compute instances. It is used for the management of creation, attaching, and detaching of the block devices to servers.
It is used for the management of networking. It is used to figure out network is working fine, and components of OpenStack communicate with one another quickly and efficiently.
It provides authentication and authorization for all the OpenStack services. It provides access through different means, by using it user easily map their existing user access methods against Keystone.
It provides telemetry services for a single point of contact for billing systems.
It provides orchestration services for multiple composite cloud-based applications. It also provides help to manage the infrastructure needed to run cloud services.
This component of OpenStack provides database-as-a-service provisioning relational and non-relational database engine.
The main goal of Sahara is to provide data processing services for OpenStack-managed resources. It provides the features of scalability by adding and removing worker nodes on demand.
