What is a Tech Stack?

“Our technology stack is the foundation of our digital capability — strategically selected layers of software and infrastructure that enable us to build, scale, and evolve products with speed, security, and confidence.”

User-Level Definition

A stack is just the combination of tools and systems that make an app or website work — from what you see on your screen to all the behind-the-scenes engines that power it.

Executive Definition

A software stack is the integrated collection of technologies used to build and run applications, websites, and platforms. These include interface frameworks, databases, APIs, servers, and infrastructure.

The stack directly influences performance, scalability, time to market, and long-term cost. It can refer to:

Application Stacks (mobile, web, desktop)
Web Hosting or Delivery Stacks
CRM and Operational Platform Stacks
Cloud Infrastructure and DevOps Tooling

Strategic stack choices unlock agility, resilience, and integration potential across the business.

Developer Definition

A stack is the full technology layer cake used to deliver software, typically including:

Front-End: HTML/CSS, JavaScript frameworks (React, Vue)
Back-End: Server-side languages (Node, Python, PHP)
Database: SQL/NoSQL (PostgreSQL, MongoDB)
Infrastructure: OS, Web Server, Containerisation, CI/CD
Supporting Services: Auth, Queues, APIs

The stack determines deployment velocity, architecture scalability, and maintenance overhead.
