blockchain

A  digital database containing information (such as records of financial  transactions) that can be simultaneously used and shared within a large  decentralized, publicly accessible network providing encrypted security.

decentralized

To distribute the administrative powers or functions of (a central authority) over a less concentrated area.

dapp

DApp is an abbreviated form for decentralized application. A DApp has its back end code running on a decentralized peer-to-peer network. Contrast this with an app where the back end code is running on centralized servers.


A DApp can have front end code and user interfaces written in any  language (just like an app) that can make calls to its back end. Furthermore, its front end can be hosted on decentralized storage such as  Swarm or IPFS.

disrupt

To radically change (an industry, business strategy, etc.), as by introducing a new product or service that creates a new market.

centralized service provider

A Centralized Service Provider uses a type of computing architecture where all or most of the processing / computing is performed on a central server. Centralized computing enables the deployment of all of a central  server's computing resources, administration and management. The central  server, in turn, is responsible for delivering application logic,  processing and providing computing resources (both basic and complex) to  the attached client machines. Having all of the information stored in one central location allows for attackers to pinpoint one location where the information exists and then execute there attack. 

AI (artificial intelligence)

A  branch of computer science dealing with the simulation of intelligent behavior in computers.

UCaaS (Unified Communications as a Service)

Unified Communications as a Service:  A category of "as a Service" or "Cloud" delivery mechanisms for Enterprise Communications. Similar to "Platform as a Service", with UCaaS, unified communications services can be made available from the cloud to enterprises. 

DDos (Denial of service attack)

In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of  a host connected to the Internet.

collaboration

Unified communications and collaboration  (UCC) refers to the combined use of communications and collaboration  solutions. UCC aggregates the communication services that people often use into a single interface. These services include  email, instant messaging, voice, click-to-dial, presence,  videoconferencing and so on. 

SaaS

Software as a service (SaaS)  is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. It is sometimes referred to as "on-demand software", and was formerly referred to as "software plus services" by Microsoft


SaaS applications are also known as Web-based software, on-demand software and hosted software. The term "software as a service" (SaaS) is considered to be part of the nomenclature of cloud computing, along with infrastructure as a service (IaaS), platform as a service (PaaS), desktop as a service (DaaS),  managed software as a service (MSaaS), mobile backend as a service (MBaaS), datacenter as a service (DCaaS), and information technology management as a service (ITMaaS). 


SaaS apps are typically accessed by users using a thin client, e.g. via a web browser.  SaaS has become a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization,  accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning management systems, content management (CM), geographic information systems (GIS), and service desk management. SaaS has been incorporated into the strategy of nearly all leading enterprise software companies.


According to a Gartner estimate, SaaS sales in 2018 were expected to grow 23% to $72 billion.
