Monolithic Architecture

Microservices

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

Service Mesh

An infrastructure layer handling service-to-service communication in microservices, managing traffic, security, and observability.

API

Application Programming Interface — a set of protocols and tools for building and integrating software applications.

REST API

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

GraphQL

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

gRPC

A high-performance remote procedure call framework developed by Google using Protocol Buffers for serialisation.

Event-Driven Architecture

An architecture pattern where the flow of the system is determined by events — significant changes in state.

Message Queue

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

Pub/Sub

A messaging pattern where publishers send messages to topics and subscribers receive messages from topics of interest.

Edge Computing

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

Content Delivery Network

A distributed network of servers that delivers web content to users based on their geographic location.

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

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

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

A database designed from the ground up to operate in cloud environments with automatic scaling and high availability.

The practice of building and maintaining internal developer platforms that provide self-service capabilities, standardised tooling, and golden paths for software delivery teams.

An approach that distributes workloads across multiple cloud providers to avoid vendor lock-in, optimise costs, meet regulatory requirements, and improve resilience.

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

Cloud infrastructure providing on-demand access to graphics processing units optimised for AI training and inference, enabling organisations to scale compute without capital investment.
