Public Cloud

Cloud Computing

The delivery of computing services — servers, storage, databases, networking, software — over the internet on demand.

Infrastructure as a Service

Cloud computing model providing virtualised computing resources like servers, storage, and networking over the internet.

Platform as a Service

Cloud computing model that provides a platform for developers to build, deploy, and manage applications without managing infrastructure.

Software as a Service

Cloud computing model that delivers software applications over the internet on a subscription basis.

Function as a Service

A serverless cloud computing model where individual functions are executed in response to events.

Serverless Computing

A cloud execution model where the provider dynamically allocates resources, charging only for actual compute time used.

Cloud-Native

An approach to building applications that fully exploit cloud computing advantages like elasticity, resilience, and automation.

Private Cloud

Cloud computing resources used exclusively by a single organisation, either on-premises or hosted by a third party.

Managed Service

A cloud service where the provider handles infrastructure management, maintenance, updates, and monitoring.

Cloud Cost Optimisation

Strategies and practices for minimising cloud computing expenses while maintaining performance and functionality.

Spot Instance

A cloud computing option that uses spare capacity at significantly reduced prices with the possibility of interruption.

Cloud Orchestration

The automated arrangement, coordination, and management of complex cloud computing systems and services.

An IT architecture combining on-premises infrastructure with public and private cloud services.

A strategy using services from multiple cloud providers to avoid vendor lock-in and optimise capabilities.

Spare cloud computing capacity offered at steep discounts compared to on-demand pricing, available when the provider has excess resources but subject to interruption.

An authentication scheme allowing users to log in once and gain access to multiple related systems.

The set of policies, technologies, and controls deployed to protect cloud-based systems, data, and infrastructure.

A query language for APIs that lets clients request exactly the data they need in a single request.

A communication method where messages are stored in a queue until the receiving application can process them.

Security solutions designed to protect server workloads running in cloud environments, providing vulnerability management, runtime protection, and compliance monitoring.
