Tag: Operating System

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Examples of popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. So-called mobile operating systems include Android and iOS. Other classes of operating systems, such as real-time (RTOS), also exist.

Ease into Kubernetes on Microsoft Azure

Managing containerized applications at scale is a new kind of challenge, especially if yoursquo;re planning on automating as much of the operations as possible.

There is a fundamental disconnect between containers and the underlying infrastructure of our datacenters, one that makes it difficult to map containers onto the available physical and virtual resources.

Thatrsquo;s where datacenter-scale tools such as Kubernetes come into play, providing an essential new management layer to control how and where our containers run.Originally developed and open sourced by a team at Google, the Kubernetes project is now managed by the independent Cloud Native Computing Foundation. Kubernetes is available on all of the major public cloud platforms including Azure. Perhaps best thought of as a datacenter operating system, Kubernetes monitors the resources used by a containerized application and deploys its elements on the underlying infrastructure to ensure that services operate correctly, managing the mapping between the requirements of the containers and the capabilities of the underlying infrastructure.To read this article in full or to leave a comment, please click here

How will the cloud change IT? Look at Microsoft

Microsoft is planning a global sales reorganization to better focus on selling cloud software, according to Microsoft insiders.

This comes as no surprise, considering that Microsoft did the same fornbsp;its ailing phone business last year. What does this mean? Well, cloud in, software outmdash;at least from the Microsoft business standpoint. However, count on Microsoft soaking you for more operating system and office automation money for years to come.
So, thatrsquo;s still a thing. To read this article in full or to leave a comment, please click here
