Vercel Migration in Derry
Migrating applications to Vercel for Derry organisations, where the database connections are what break first. A long-running server holds a handful of connections; serverless functions each want their own, so traffic that was comfortable before exhausts the database's connection limit almost immediately after the move.
Why this comes up
The problem
The application moved to serverless functions and the database now refuses connections under normal load.
What you get
What we deliver
- Connection pooling introduced so functions share a bounded set of connections
- Long-running work identified, since execution time is capped on serverless
- Background jobs and scheduled tasks given somewhere appropriate to run
- In-memory state removed, as instances are created and discarded unpredictably
- File writes relocated, because the filesystem is not persistent between invocations
- Rendering strategy chosen per route rather than applied uniformly

Vercel Migration in Derry — common questions
- Why do connections run out?
- Because each function instance opens its own. A traditional server maintains a small pool for all requests, whereas concurrent serverless invocations each connect independently — so a database configured for a hundred connections is exhausted by a hundred simultaneous requests.
- How is that fixed?
- With a pooler in front of the database, or a driver designed for serverless access. Both keep the number of actual connections bounded regardless of how many functions are running, and one of them needs to be in place before the migration rather than after.
- What about long-running work?
- It needs somewhere else. Functions have an execution limit, so report generation, large imports and anything taking minutes will be terminated mid-way — a queue with a worker running elsewhere handles those far better than trying to fit them into the limit.
- Can we write files?
- Not durably. Anything written during an invocation disappears with the instance, so uploads, generated documents and caches on disk all need moving to object storage — which is easy to overlook because it works fine in local development.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
