Ansible


Ansible is an open source IT configuration management (CM) and automation platform, provided by Red Hat. It uses human-readable YAML templates so that users can program repetitive tasks to occur automatically, without learning an advanced language.

Ansible replaces ad hoc scripting or manual CM with an automated and repeatable process. The tool pushes application code, programs and IT infrastructure setup instructions via modules to managed nodes, whether physical servers, virtual machines (VMs) or cloud instances. The tool also gives users the option to invert its setup to a pull architecture, where managed nodes request instructions from the tool, typically done to enable scaling.

Ansible components

An Ansible user sets up instructions as commands or packages them into reusable plays, executed in playbooks. Ansible performs an orchestration function, giving the user control over the order in which it carries out automated steps.

Ansible is agentless, meaning that it does not install software on the nodes that it manages. This removes a potential point of failure and security vulnerability and simultaneously saves system resources.

The CM tool integrates with other systems management and hosting technologies, including asset libraries, monitoring and collaboration software, and cloud and virtualization platforms. Ansible can control Windows systems using Windows Remote Management (WinRM). The Ansible control node must be Linux, with Python 2.6 or greater.

Black swan

A  black swan event  is an incident that occurs randomly and unexpectedly and has wide-spread ramifications. The event is usually followed with reflection and a flawed rationalization that it was inevitable. The phrase illustrates the frailty of inductive reasoning and the danger of making sweeping generalizations from limited observations. The term came from the idea that if a man saw a thousand swans and they were all white, he might logically conclude that all swans are white. The flaw in his logic is that even when the premises are true, the conclusion can still be false. In other words, just because the man has never seen a black swan, it does not mean they do not exist. As Dutch explorers discovered in 1697, black swans are simply outliers -- rare birds, unknown to Europeans until Willem de Vlamingh and his crew visited Australia. Statistician Nassim Nicholas Taleb uses the phrase black swan as a metaphor for how humans deal with unpredictable events in his 2007...

A Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a computer chip that performs rapid mathematical calculations, primarily for the purpose of rendering images. A GPU may be found integrated with a central processing unit (CPU) on the same circuit, on a graphics card or in the motherboard of a personal computer or server. In the early days of computing, the CPU performed these calculations. As more graphics-intensive applications such as AutoCAD were developed; however, their demands put strain on the CPU and degraded performance. GPUs came about as a way to offload those tasks from CPUs, freeing up their processing power. NVIDIA, AMD, Intel and ARM are some of the major players in the GPU market. GPU vs. CPU A graphics processing unit is able to render images more quickly than a central processing unit because of its parallel processing architecture, which allows it to perform multiple calculations at the same time. A single CPU does not have this capability, although multi...

6G (sixth-generation wireless)

6G (sixth-generation wireless) is the successor to 5G cellular technology. 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. One of the goals of the 6G Internet will be to support one micro-second latency communications, representing 1,000 times faster -- or 1/1000th the latency -- than one millisecond throughput. The 6G technology market is expected to facilitate large improvements in the areas of imaging, presence technology and location awareness. Working in conjunction with AI, the computational infrastructure of 6G will be able to autonomously determine the best location for computing to occur; this includes decisions about data storage, processing and sharing.  Advantages of 6G over 5G 6G is expected to support 1 terabyte per second (Tbps) speeds. This level of capacity and latency will be unprecedented and wi...
