Platform as a Service

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.

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.

Public Cloud

Cloud computing resources shared among multiple organisations and available to the general public over the internet.

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 software architecture where all components are tightly integrated into a single deployable unit.

An architectural style structuring an application as a collection of loosely coupled, independently deployable services.

An API architectural style using HTTP methods and stateless communication for web service interaction.

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

The process of moving workloads back from public cloud environments to on-premises or private cloud infrastructure.

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

Cloud computing practices that minimise environmental impact through renewable energy usage, efficient cooling, workload consolidation, and carbon-aware scheduling of compute tasks.
