OpenStack grows in the interest of suppliers and companies and starts to be the benchmark for the cloud and companies in digital transformation.
OpenStack is a modular cloud platform whose function is to provide process and storage management services in accordance with the classic Cloud Infrastructure as a Service (IaaS) model.
Created in 2010 under NASA's supervision and with Rackspace's involvement, it has been growing rapidly thanks to its "Open" and contribution to and interest in a number of industrial sectors that have led to increased acceptance.
Another qualifying aspect is to be a software written in Python and to use other software as open. In short, it has given rise to a very large world community that includes dozens of companies that contribute steadily to the development of the project and numerous thousands of active developers.
It is the object of the declared interest and support of world giants of IT and services, which has contributed to its increasingly broad acceptance. Among platinum members, for example, it includes AT & T, Ericsson, Huawei, IBM, Intel, Rackspace, Red Hat and Suse.
Nutrition and the highest level of users, including world-class companies such as Bloomberg, Comcast, PayPal or Wells Fargo.
Central to its diffusion is the OpenStack Foundation, the organization that has the task of promoting OpenStack software and whose outline spins the community that includes developers and users.
To whom it is addressed and what it allows
Cloud platform written in Python, OpenStack was designed to manage computing, storage, and network pool cloud resources using classic command line interface (CLI) or web interface. The operating system on which it is based is another of the pillars of an open system, Linux, in its various variants such as RedHat, Suse, Ubuntu and others.
Through CLIs or web interfaces, you can configure virtual IT environments within which to allocate the necessary resources, but they are not constrained to be in a single physical place but can be deployed.
This makes it an ideal platform for deployed applications for web service delivery, Big Data management and analysis, or Network Function Virtualization (NFV) services, and as such is of great interest also for service providers in phase Renewal of their network infrastructure and engaged in the delivery of new value-added services.
A modular and open cloud architecture
As mentioned, a key aspect of OpenStack is to be modular. Referring to the scheme of the official site of the project, the schema shows how the core of the software consists of three main functions: calculation, network and storage.
These features or entities are managed in their entirety by a data center that allocates the required resources by interacting with the user through a dashboard accessible through a browser or API. The most important projects of Openstack relate to the following modules:
- Nova (Calculation): Controls the entire platform and manages virtual machine instances and internal communication. It performs numerous services such as allocation of instances on physical machines or interaction with the hypervisor of the latter to handle instances.
- Neutron (Network): is dedicated to network communication.
- Swift: It is a highly-deployed high-reliability storage and scalability designed to handle large volumes of data for backup or online applications.
- Keystone: handles authentication and authorization for the various OpenStack modules.
- Glance (Image Service): Handles virtual imagery and consists of a database, a virtual image cataloging service, and a set of APIs for interaction.
- Cinder (Block Storage): It is responsible for saving the data.
These six main modules are added to Horizon (Dashboard), which represents the Web User Interface.
