Apache Cassandra is a free and open-source distributed wide column store NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
In computer programming, an application programming interface (API) is a set of subroutine definitions, protocols, and tools for building software.
An application software (app or application for short) is a computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming.
A computer cluster is a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.
A database is an organized collection of data, stored and accessed electronically.
In data storage, disk mirroring is the replication of logical disk volumes onto separate physical hard disks in real time to ensure continuous availability.
DRBD is a distributed replicated storage system for the Linux platform.
E-commerce is the activity of buying or selling of products on online services or over the Internet.
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
In computing and related technologies such as networking, failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network.
In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system.
Hector is a high-level client API for Apache Cassandra.
High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.
High availability software is software used to ensure that systems are running and available most of the time.
HP Serviceguard, formerly known as MC/ServiceGuard, is a high-availability cluster software produced by HP that runs on HP-UX and Linux.
Hyper-converged infrastructure (HCI) is a software-defined IT infrastructure that virtualizes all of the elements of conventional "hardware-defined" systems.
IBM PowerHA SystemMirror (formerly IBM PowerHA and HACMP) is IBM's solution for high-availability clusters on the AIX Unix and Linux for IBM System p platforms and stands for High Availability Cluster Multiprocessing.
In computing, a Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/OS.
The Linux-HA (High-Availability Linux) project provides a high-availability (clustering) solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS).
A network address is an identifier for a node or host on a telecommunications network.
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients.
OpenSAF is an open-source software project to develop high availability middleware consistent with Service Availability Forum (SA Forum) specifications, under the LGPLv2.1 license.
Pacemaker is an open-source high availability resource manager software used on computer clusters since 2004.
A power supply is an electrical device that supplies electric power to an electrical load.
A quorum is the minimum number of votes that a distributed transaction has to obtain in order to be allowed to perform an operation in a distributed system.
The Red Hat Cluster includes software to create a high availability and load balancing cluster.
In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
The SAFplus Availability/Scalability Platform is an open source software library used to provide high availability, scalability/clustering, and management services for software applications running in a tightly coupled distributed system.
In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".
The Service Availability Forum (SAF or SA Forum) is a consortium that develops, publishes, educates on and promotes open specifications for carrier-grade and mission-critical systems.
A shared-nothing architecture (SN) is a distributed-computing architecture in which each node is independent and self-sufficient, and there is no single point of contention across the system.
Oracle Solaris Cluster (sometimes Sun Cluster or SunCluster) is a high-availability cluster software product for Solaris, originally created by Sun Microsystems, which was acquired by Oracle Corporation in 2010.
Split-brain is a computer term, based on an analogy with the medical Split-brain syndrome.
A storage area network (SAN) is a Computer network which provides access to consolidated, block level data storage.
An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
Urgent computing is prioritized and immediate access on supercomputers and grids for emergency computations such as severe weather prediction during matters of immediate concern.
Veritas Cluster Server (rebranded as Veritas Infoscale Availabilty and also known as VCS and also sold bundled in the SFHA product) is a high-availability cluster software for Unix, Linux and Microsoft Windows computer systems, created by Veritas Technologies.
