Redis Integration in London
Integrating Redis into London applications, where the question worth settling early is whether it is an optimisation or a dependency. If the system still works when the cache is empty, it is a cache; if losing it takes the application down, it is a database holding your data in memory — and those two things need very different treatment.
Why this comes up
The problem
Session data lives only in Redis, and a restart logs out every user on the platform.
What you get
What we deliver
- Cache and store distinguished, so what must survive a restart is identified
- Persistence configured where data cannot simply be regenerated
- Eviction policy chosen deliberately rather than left at the default
- Expiry set on cached entries, since memory is finite and fills quietly
- Cold-start behaviour tested, so an empty cache does not overwhelm the database
- Failure handled gracefully, with the application degrading rather than stopping

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Redis Integration in London — common questions
- Is Redis a cache or a database?
- Either, and the design differs sharply. Used as a cache, losing it costs performance briefly; used as a store for sessions, queues or counters, losing it costs data — so the decision determines whether persistence and replication are optional or essential.
- Why does the eviction policy matter?
- Because it decides what happens when memory fills. The default may reject writes rather than discard old entries, which turns a full cache into application errors — and for genuine caching, evicting least-recently-used keys is almost always the behaviour you actually want.
- What is the cold-start risk?
- Every request missing the cache at once. When Redis restarts empty, traffic that was being served from memory hits the database simultaneously, and a system sized on the assumption of a warm cache can fall over at exactly the moment it is recovering.
- Should the application survive Redis being down?
- Wherever it reasonably can. A cache lookup that fails should fall through to the source rather than raising an error, so an outage in the cache layer slows the application instead of stopping it — and that behaviour needs testing deliberately, because it is never exercised in normal operation.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
