MDADM is a Linux tool used to create, manage and monitor sofware RAID arrays (RAID 0, 1, 4, 5, 6 and 10). It's a free tool that can also be used aside from Linux, like raidtools developed by SUSE.
It also enables particular non-raid situations like Multipath and Failover with different "voluems" on the same physical disk in order to simulate fault situations.
Kubernetes is a container orchestration tool. Developed mostly by Google, it saw a quick spread thanks to its capabilities of optimizing, improving and automating a large amount of manual management operations (deployment, deletion, creation, etc..).
ALOHA is a network protocol developed by the University of Hawaii in 1971 as a first demonstration of the operation of wireless networks on UHF frequencies. This protocol has laid the groundwork for the definition of the following Ethernet and WiFi protocols.
The acronym LTSC (Long Term Servicing Channel), referring to the Microsoft world, characterizes the server products that are accompanied by a policy of releasing updates "slower" and with a cadence of two to three years between each major release. Compared to the SAC policy, the nomenclature of server operating systems is of the YYYY type, rather than YYMM (with Y = year and M = month).
The acronym SAC (Semi Annual Channel), referring to the Microsoft world, characterizes the server products that are accompanied by a policy of issuing of the semi-annual, customer-oriented policy that regularly require the latest features available. The service model is the same that characterizes the Windows 10 client operating system, with about six-month macro-relase and a YYMM type nomenclature (Y = Year, M = month).
Project Honolulu is the new Web platform (based on HTML 5) for centralized management of hosts and clusters in a Microsoft Windows Server environment. After being made available as a technical preview, in the next release Windows Server 2019 will be integrated in all respects.
The acronym WSL (Windows Subsystem for Linux) indicates the technology (a set of software components) introduced by Microsoft that allows you to run Linux commands inside a Windows Server 2016 or 10.
This is a limited Linux environment and exclusively on the command line, so not a real Linux machine.
The acronym RIP (Routing Information Protocol) indicates a distance vector routing protocol, which as a path calculation metric uses the number of hops (jumps), up to a maximum of 15 units and to avoid loops.
The term Serverless Computing describes a cloud computing model where the provider deals with the distribution of computational resources, while the processing cost is calculated only on the basis of the consumption of the application in use, or on pre-purchased computing capacity.
Of course the computational power is provided by physical servers, but the term Serverless emphasizes that this aspect is completely transparent to the developer.
The acronym IoE (Internet of Everything) describes a context in which commonly used devices and products are all connected to the Internet and equipped with digital capabilities. In this ideal, in the future everything will be connected to the global network.
The term Snippet indicates an extract of code that is short, reusable and easily integrated into larger codes. For example, a snippet can be composed of some lines of code that implement a certain function through parameters that are independent of the surrounding code.
A Zero Day Exploit describes a situation in which specific and unknown vulnerabilities are disclosed to the public simultaneously with the discovery of the same. This is a potentially very risky situation, because in the immediate future there are no patches or solutions that can secure the exploit.
InfiniBand is an input / output architecture for the transmission of data between high performance systems composed of CPUs, processors and storage and characterized by high working frequencies, very low latencies and wide scalability.
IB architectures are realized through networks composed of switches with throughput higher than those typical of broadcast architectures like Ethernet. The maximum data transfer rate is around 40 Gbps.
The acronym DPO (Data Protection Officer) indicates the person or persons who, within the company context, are responsible for the correct application and compliance of the regulation on data processing (GDPR).
The acronym GDPR indicates the new General Data Protection Regulation, which will come into force on 25 May 2018. This is the single and mandatory regulation for the whole European Union and that replaces the previous law on Privacy. The purpose of this provision is to restore the control of personal data to users and to intervene more precisely in case of data breach.
In the field of Information Technology, the term piggybacking refers to situations where an unauthorized third party gains access to protected systems, exploiting the collaboration with an entity that is authorized to do so.
Hold Down Timer is a technique used by network routers. When a node receives notification that another router is offline, it starts a tolerance timer to allow time for offline devices to recover, without having to update their respective routing tables accordingly.
Blockchain is a process in which a set of subjects (or nodes) shares computing and computing resources, to make available to the community a virtual database in which each participant has a copy of the data contained. The system is regulated by a cryptographic protocol considered safe by the community itself.
The acronym LRDIMM (Load Reduce DIMM) indicates a specific type of RAM memory (of the Registered DIMM family) that replaces the memory register with an isolated circuit called Isolated Memory Buffer. This component buffers commands, memory addresses and data signals and isolates the host controller's memory chip. In practice, the physical host "reads" only the iMB chip upstream of the desk and allows an increase in storage capacity up to 100%.
WSL stands for Windows Subsystem for Linux, a resource that makes possible to run Linux commands on Windows systems, allowing developers to work on Windows machines and leveraging commands of the open source OS. It was introduced in Windows 10 version 1607.
The term Cloud Orchestration describes the techniques of cloud process automation to certain goals. Unlike simple automation, which deals with individual and specific tasks, orchestration "understands" and manages entire sets of tasks and processes.
IRQ (Interrupt Request) indicates an asynchronous signal sent to the processor by a certain device that implies the execution of a certain command.
This kind of interrupts is generated by the hardware parts the machine is composed, unlike software IRQs that are generated by a certain software state, so not related to a physical device.
IPsec (Internet Protocol Security) is a set of protocols that provide security for the IP protocol itself, like additional authentication options, integrity control a data encryption. It’s often used to realize secure VPN networks.
The term ISP, which stands for Internet Service Provider, refers to these companies that provide their clients with Internet connectivity. This service is offered using different technologies; traditionally, via twisted-pair cabling, and more recently, optical fibre (to-the-home or to-the-cabinet).
