Digital Vision for Cloudification


Multicloud, PaaS, Swarm Computing. What does all this mean? Consult our lexicon to understand the A-Z of Cloudification!

AI (Artificial Intelligence)

Applies advanced analysis and logic-based techniques, including machine learning, to interpret events, support and automate decisions, and take actions.

API (Application Programming Interface)

A set of subroutine definitions, communication protocols, and tools for building software.


An expanding list of cryptographically signed, irrevocable transactional records shared by all participants in a network. Each record contains a time stamp and reference links to previous transactions.

CIO (Chief Information Officer)

Oversees the people, processes and technologies within a company’s IT organisation to ensure they deliver outcomes that support the goals of the business.

Client/server setup

The splitting of an application into tasks performed on separate computers connected over a network. In most cases, the “client” is a desktop computing device (e.g., a PC) or a program “served” by another networked computing device (i.e., the “server”).

Cloud computing

A style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies.

Cloud orchestration

The process to manage multiple workloads, in an automated fashion, across several cloud solutions, with the goal being to synthesise this into a single workflow.

Deep Learning

Part of a broader family of machine learning methods based on learning data representations, as opposed to task-specific algorithms.


The use of digital technologies to change a business model and provide new revenue and value-producing opportunities; it is the process of moving to a digital business.

Edge computing

A cloud computing solution that performs the same functions as a central cloud computing or storage server on a decentralised location closer to the local devices.

GDPR (General Data Protection Regulation)

A regulation in EU law on data protection and privacy for all individuals within the European Union (EU) and the European Economic Area (EEA). It also addresses the export of personal data outside the EU and EEA areas.

Hybrid Cloud Computing

Refers to policy-based and coordinated service provisioning, use and management across a mixture of internal and external cloud services.

IaaS (Infrastructure as a service)

A standardised, highly automated offering, where compute resources, complemented by storage and networking capabilities are owned and hosted by a service provider and offered to customers on-demand.

IoT (Internet of Things)

The network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment.

LAN (local-area network)

A geographically limited communication network that connects users within a defined area. A LAN is generally contained within a building or small group of buildings and is managed and owned by a single enterprise.


Measure of the responsiveness of a network, often expressed as the round-trip time (in milliseconds); that is, the time between initiating a network request and receiving a response.

Legacy application

An information system that may be based on outdated technologies, but is critical to day-to-day operations.

ML (Machine Learning)

Advanced machine learning algorithms are composed of many technologies (such as deep learning, neural networks and natural-language processing), used in unsupervised and supervised learning, that operate guided by lessons from existing information.

Moore’s Law

The observation that the number of transistors in a dense integrated circuit doubles about every two years.


The use of multiple cloud computing and storage services in a single heterogeneous architecture.

Open source

Describes software that comes with permission to use, copy and distribute, either as is or with modifications, and that may be offered either free or with a charge.

PaaS (Platform as a service)

A PaaS offering, usually depicted in all-cloud diagrams between the SaaS layer above it and the IaaS layer below, is a broad collection of application infrastructure (middleware) services (including application platform, integration, business process management and database services).

Private Cloud Computing

A form of cloud computing that is used by only one organisation, or that ensures that an organisation is completely isolated from others.

Public Cloud Computing

A style of computing where scalable and elastic IT-enabled capabilities are provided as a service to external customers using Internet technologies—i.e., public cloud computing uses cloud computing technologies to support customers that are external to the provider’s organisation.

SaaS (Software as a service)

Software that is owned, delivered and managed remotely by one or more providers.

Swarm Computing

A cluster of intelligent devices working in tandem in which the many independent devices are grouped together to become one ‘swarm’ of interconnected units, each supplying a small amount of data and processing power which, when combined, provide enough information, intelligence and independence to enable localised, time-sensitive data processing and decision making.

TPU (Tensor Processing Unit)

An AI accelerator application-specific integrated circuit developed by Google specifically for neural network machine learning.
