Companies Using Amazon Web Services in Cardiff: 140 Active Firms (2026)
Cloud infrastructure users run public-facing websites on scalable hosted compute and storage, within Cardiff and its metropolitan area.
Adoption usually sits with engineering, digital operations and marketing-technology teams rather than general IT alone. The public cloud stack provides rented compute, storage, networking and deployment services for public-facing sites, customer portals and transactional applications. Companies running this stack tend to have more than a brochure site: uptime monitoring, release processes, security controls and campaign measurement are part of the operating model. Typical users skew towards mid-market and larger organisations with recurring digital demand, including B2B services, consumer-facing platforms and institutions where web traffic, content delivery or seasonal usage patterns make conventional hosting less attractive.

Cardiff has 140 actively trading companies running this cloud infrastructure stack on public-facing websites. Reported employment across the cohort totals 896 people, which points to a user base weighted towards small operating teams rather than very large local employers. The adoption mix is not confined to software: Travel & Hospitality accounts for 28.6% of the cohort, with Education & Training at 7.1%, Advanced Manufacturing at 5.7%, Sport & Leisure at 5.0% and SaaS also at 5.0%. Only 7 companies report turnover above £5M, so the Cardiff picture is more about practical cloud use across digital operators than a concentration of large platform businesses.
Companies running public cloud infrastructure inherit a procurement and governance workload even when the underlying platform is outsourced. GDPR remains the main reference point where customer accounts, booking flows, payment journeys or analytics tags involve personal data, with the ICO setting expectations on lawful basis, retention and breach handling. Public-sector or education-adjacent users will usually need clearer evidence on access controls, audit logging, supplier due diligence and data location. The wider stack often includes content delivery, object storage, analytics, tag management and bot-checking services, so accountability tends to sit across engineering, digital, legal and procurement rather than with a single systems owner.
Adoption appears likely to deepen through incremental migration rather than wholesale replatforming. Cardiff’s cohort looks broad by sector but relatively modest by company scale, so many users will tend to expand cloud use around specific workloads: traffic management, media delivery, customer portals, booking flows and internal tooling. Cost governance may become more visible as finance teams scrutinise recurring infrastructure spend, while privacy and security reviews are likely to shape procurement for organisations handling customer or student data. Supplier consolidation may also matter, as cloud hosting, delivery, monitoring and identity controls are increasingly bought as connected parts of the operating stack.

Key facts
About 5% of the trading cohort reports turnover above £5M (7 of 140 firms) — the rest sits below that revenue band.
13% of the cohort was incorporated since 2022 (19 firms), so a sizeable share is in its first few filing cycles.
59.3% of Cardiff users also run a content-delivery layer, pointing to public-facing sites built for cached delivery rather than simple brochure hosting.
41.4% also show object-storage usage, consistent with websites and applications serving files, media or backups from hosted storage.
Travel & Hospitality is the largest tagged sector in the Cardiff cohort at 28.6%, ahead of Education & Training at 7.1%.
Financial-risk classifications are mixed: 24.3% are classed as stable, while 20.7% are weak and 7.1% are distressed.

How Amazon Web Services usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
