Microservices

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

Monolithic Architecture

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

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

Message Queue

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

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

The automated management of containerised application deployment, scaling, networking, and availability across clusters of machines, with Kubernetes as the dominant platform.

Software that creates and manages virtual machines, allowing multiple operating systems to share a single hardware host.

A data storage architecture managing data as objects rather than file hierarchies or block addresses.

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

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

Managing and provisioning computing infrastructure through machine-readable configuration files rather than manual processes.
