jBPM is a toolkit for building business applications to help automate business processes and decisions. jBPM originates from BPM (Business Process Management) but it has evolved to enable users to pick their own path in business automation. It provides various capabilities that simplify and externalize business logic into reusable assets such as cases, processes, decision tables and more. business processes (BPMN2) case management (BPMN2 and CMMN) decision management (DMN) business rules (DRL) business optimisation (Solver) jBPM can be used as standalone service or embedded in custom service.

Programmers use a command-line interface (CLI) to issue text-commands to the Operating System (OS), instead of clicking on a Graphical User Interface (GUI). This is because command-line inerface is much more powerful and flexible than the graphical user interface. The Terminal application is a command-line Interface (or shell). By default, the Terminal in Ubuntu and macOS runs the so-called bash shell, which supports a set of commands and utilities; and has its own programming language for writing shell scripts.

Transmission Control Protocol (TCP) is a communications standard that enables application programs and computing devices to exchange messages over a network. It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks. TCP is one of the basic standards that define the rules of the internet and is included within the standards defined by the Internet Engineering Task Force (IETF). It is one of the most commonly used protocols within digital network communications and ensures end-to-end data delivery.

Redis is an open source (BSD licensed), in-memory data structure store used as a database, cache, message broker, and streaming engine. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

Redis Sentinel is the high-availability solution for open-source Redis server. It provides monitoring of all Redis nodes and automatic failover should the master node become unavailable. This guide provides a sample configuration for a three-node Redis cluster. Sentinel itself is designed to run in a configuration where there are multiple Sentinel processes cooperating together. The advantage of having multiple Sentinel processes cooperating are the following : Failure detection is performed when multiple Sentinels agree about the fact a given master is no longer available.

Machine learning is a branch of artificial intelligence (AI) and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy. How Does Machine Learning Works? Similar to how the human brain gains knowledge and understanding, machine learning relies on input, such as training data or knowledge graphs, to understand entities, domains and the connections between them. With entities defined, deep learning can begin.
