Next-generation cloud services
OpenStack is a cloud operating system that controls large quantities of distributed compute, storage, and networking resources within datacentre environments, all managed through an interface that administrators can control while empowering their users to be able to provision resources through a web interface. OpenStack improves business agility, availability, and efficiency by providing such a developed platform with on-demand and highly elastic services capabilities that can be fully monitored and measured.
Not just a virtualisation management platform
There are many virtualisation management platforms around however OpenStack takes it to the next level by operating as a fully functioning cloud platform. By definition, users have the ability to request compute, network, and storage resources on demand.
How does OpenStack work?
OpenStack has a series of components which are basically a series of scripts that are bundled into projects. OpenStack relies upon virtualisation and Linux-based operating systems that carry out the commands supplied by the scripts. Fundamentally OpenStack is the framework and infrastructure that builds cloud environments.
Core OpenStack Components
There are a lot of components that make up OpenStack. Nevertheless, not all components are created equal and the key 6 modules which feature in all environments are as follows:
The Nova service handles the creation, deletion, and general management of virtual machines
The neutron service connects the networks across the OpenStack services.
Cinder is the OpenStack block storage service that is traditionally deployed on Ceph. Ceph is a unified and distributed storage system designed for performance, reliability, and scalability. Ceph with Cinder, therefore, allows for scalability and redundancy for storage volumes. Coreix solutions all utilise Ceph with OpenStack.
Swift is a highly available and distributed object/blob store for OpenStack. This is required for storing unstructured data objects utilising a RESTful API.
Image Storage Repository
Glance manages virtual machine disk images and acts as a central repository for those images.
The Keystone component authenticates and authorises OpenStack services. Fundamentally the core OpenStack service providing API client authentication, service discovery, and distributed multi-tenant authorisation.
The OpenStack orchestration capabilities offer developers, administrators and IT professionals faster and better access to IT resources which means users can provision virtual machines rapidly as required which can significantly reduce development and testing periods, in addition, allowing users the freedom to sandbox and experiment with new ideas as they arise.
OpenStack solutions may seem expensive at the top end private cloud level, however, when you break this down to an individual virtual machine and per GB storage cost the savings are in plain sight.
Whether this is public, private, or hybrid cloud solutions, OpenStack is by far one of the most cost-effective solutions on the market.
