Software 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.

Platform as a Service

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

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.

A lightweight, portable software package that bundles application code with all its dependencies for consistent execution.

Processing data near the source of data generation rather than in a centralised cloud data centre.

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

A cloud computing model that enables the replication and recovery of infrastructure and data in the cloud.

A platform for developing, shipping, and running applications in isolated containers with consistent environments.

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.

An open-source container orchestration platform for automating deployment, scaling, and management of containerised applications.
