What is an operating system?

An operating system (OS) is the Application Which, after being initially loaded into the computer by a boot program, oversees all the other application programs in a computer. The application programs make use of the working system by making Furthermore, users can interact directly with the operating system Via a user interface like a command line or a graphical user interface (GUI).

Types of operating systems.

Operating systems normally include pre-loaded on almost any Computer you purchase. Many men and women use the operating system which comes with their computer, however it is possible to update or perhaps alter operating systems. The three most frequent operating systems for personal computers are Microsoft Windows, macOS, and Linux. A GUI enables you to use your mouse to click on icons, switches , and menus, and that which is clearly displayed on the display by means of a combo of images and text. Each operating system's GUI includes a different feel and look, so if you Switch to another operating system it might appear unfamiliar at first. However, modern operating systems have been made to be effortless to utilize , and the majority of the fundamental principles are exactly the same.

Microsoft established the Windows operating platform at the mid-1980s. There have been a number of distinct variants of Windows, but the latest ones are Windows 10 (published in 2015), Windows 8 (2012), Windows 7 (2009), along with Windows Vista (2007). Windows includes pre-loaded on many new PCs, which helps to ensure it is the hottest operating system on the planet.

MacOS (formerly called OS X) is a Lineup of operating systems made by Apple. It comes preloaded on all Macintosh computers, or Macs. A number of the specific models include Mojave (published in 2018), High Sierra (2017), and Sierra (2016). Based on StatCounter Global Stats, macOS users accounts for significantly less than 10 percent of international functioning systems--considerably lower than the percent of Windows users (greater than 80 percent ). 1 reason behind this is that Apple computers have a tendency to be costlier. But a lot of individuals do prefer the appearance and feel of macOS over Windows.

Linux (pronounced LINN-ux) is a household of open-source operating systems, so they may be altered and distributed by all around the globe. This differs from proprietary program such as Windows, which may only be altered by the organization that owns it. The benefits of Linux are that it's free, and there are several different distributions or variations you may select from. Based on StatCounter Global Stats, Linux users accounts for under 2 percent of international functioning systems. But most servers run Linux since it's relatively simple to personalize.

The operating systems we have been speaking about so much were created to operate on desktop and notebook computers. Mobile apparatus like telephones , tablets , and MP3 players Are distinct from desktop and notebook computers, so that they run operating systems that have been designed especially for mobile devices. From the screenshot below, you can view iOS running in an iPad. Operating systems for mobile devices normally are not as fully featured As those created for desktop and notebook computers, and they are not capable to Run each the exact same software. But, you can still perform a Great Deal of things Together, like watch videos, browse the net, manage your calendarand play games.

Ubuntu Blog: What’s new in Open Source MANO: multi-cloud orchestration, operator lifecycle management, and more..

Open source MANO (OSM) community recently added two more bricks in the wall of NFV orchestration events: OSM Release NINE and OSM#10 Hackfest. The community has come a long way to mature OSM into its 9th version. A toast to all the system integrators, network operators, researchers, and VNF vendors who have hit the home run there!

Canonical’s contribution towards the OSM Release NINE highlights the model-driven capabilities for network services onboarding. This model-driven approach paves the way towards the goal of multi-cloud orchestration using centralized OSM components. Another major integration is the alignment of the OSM network model with ETSI (European Telecommunication Standard Institute) SOL006 standards.

Canonical being a key member of the OSM community, also participated in Hackfest, and in collaboration with other stakeholders, covered the majority of the hackfest sessions. The event held once again behind the screens from Nov 30 to Dec 4, 2020 and focused on enhancing community interactivity and encouraging developers to participate in the project.

Canonical in OSM#10 Hackfest – The highlights

Canonical’s engagement in OSM#10 Hackfest was aiming to drive better lifecycle management of network services using a model-driven approach. The team was present both as instructors in Hackfest sessions and leaders in community technical sessions.

The Hackfest sessions were categorized into Operations, VNF onboarding, and OSM Ecosystem progression. The first three days were focused on deployment and operations of network functions over bare-metal machines, virtual machines (VMs), and Kubernetes-managed containers. The fourth day was focused on creating network descriptor packages from scratch and onboarding of virtual network functions (VNFs), physical network functions (PNFs), and Kubernetes network functions (KNFs) using operators (Juju Charms). Finally, the fifth day focused on good practices for OSM development. You can follow the event agenda on the OSM wiki for videos and presentations.

Following are some highlights presented by Canonical during the event

Model-driven Universal Operator Lifecycle Manager: Mark Shuttleworth (CEO at Canonical, and OSM technical steering committee (TSC) member) demonstrated how model-driven operators address challenges of network service lifecycle management. VNF configuration and abstraction (VCA) component in OSM provides universal operators for deployment of network services on underlying infrastructure of bare metal machines, VMs, and K8s clusters. VCA is now able to provide dynamic integration of operators in production environments which implies that service providers can add and integrate operators with the existing model.  Multiple sessions on this topic were covered by David Garcia (module development lead (MDL) for N2VC (network to VNF communication)). In the end, followed by many efforts of the environment setup and preparation of Hackfest, a session on the guidelines for OSM development was covered by Mark Bariel (MDL for DevOps) 

TATA Charmed 5G Deployment: Another exciting news on Charmed OSM, leveraging the management capabilities for 5G telco workloads, was announced by TATA ELXSI. The functional ability of Juju’s controller and Charmed OSM made possible the deployment of 5G Kubernetes network functions (KNFs) on MicroK8s infrastructure. All the components, i.e. Radio Access Network (RAN) and 5G Core, have been based on a model-driven operator framework that can be reused, upgraded, and integrated according to the current demands. We congratulate TATA ELXSI on this step forward!

Charmed 5G System Overview

OSM Release NINE – New ingredients in the OSM recipe 

OSM Release NINE is at the end of the tunnel to offer compelling features to telcos, system integrators, VNF vendors, and all the curious minds out there in the NFV world. 

The technical plenary meetings for OSM Release NINE were held in parallel to the Hackfest sessions. The main offerings by Canonical are summarised below

Multi-Cloud scenario manager: Progressing towards “distilling your operations into code”, OSM VCA (Juju) is targeting multi-cloud support for future releases, which will allow service providers to deploy and integrate network services across various virtual infrastructure managers (VIMs). This will also enable the decomposition of even very complex network services, consisting of bare metal machines, VMs, and containers, and integrating them from a centralized unit with a consistent user experience.

Upgrades in VCA: OSM supports both proxy and native charms (operators). In native charms, operator and workload are co-located in the same machine, and in proxy charms, they reside in different machines. The addition of distributed proxy charms brings the operator near to workload on registered clouds of the same VIM. In this case, the operator can be deployed anywhere away from OSM (edge) which reduces the possibility of a single point of failure and unlocks geo-redundancy in the future roadmap of OSM.

Some other major features in the OSM Release NINE include:

  • Multi-tenancy in Grafana: In previous releases, common credentials have been used for Grafana dashboards. Now, by extending the OSM’s role-based access control (RBAC) feature, the users can access the Grafana dashboards using the OSM’s credentials.
  • Support of VCA deployment in Kubernetes using Charmed OSM installer.  
  • Support for modeling Kubernetes descriptor units using Helm version 3 and Juju bundles.
