Decoded: Technology

Scalability is the ability of a system, product or business to handle more work, more users or more customers without breaking, slowing to a crawl or needing costs to grow just as fast. A scalable setup can grow by adding resources in a planned way instead of being rebuilt from scratch.

Cloud vs on-prem is the choice between running software and data on servers rented from a provider over the internet (cloud) or on hardware a company owns and operates in its own building or data center (on-premises). The decision shapes cost, control, security responsibilities, speed of setup and who fixes things when they break.

SaaS, short for software as a service, is software you use over the internet and pay for on a subscription, usually per user per month or per year. The provider runs the servers, handles updates, security and backups, and you simply log in through a browser or app instead of installing and maintaining it yourself.

An MVP, short for minimum viable product, is the smallest version of a product that real users can actually use, built to test whether an idea is worth pursuing. It includes only the core features needed to solve one problem, so a team can launch quickly, collect feedback and decide what to build next.

Tech debt, short for technical debt, is the future cost of choosing a quick or limited solution in software instead of a better one that would take longer. Like financial debt, it can be useful in the short term, but it builds interest: every later change becomes slower, riskier and more expensive until someone pays it down.

An API, short for application programming interface, is a set of rules that lets one piece of software request data or actions from another. Instead of a person copying information between systems, one app sends a structured request, the other sends back a structured answer, and neither needs to know how the other works inside.
