FAQ

When should we start thinking about scalability?
Now. Good scalability practices (caching, database indexing, stateless design) cost almost nothing to implement upfront but are extremely expensive to retrofit. We build scalable foundations from day one and layer advanced scaling as traffic demands it.
Can you scale our existing application without rewriting it?
Usually, yes. 80% of scaling is optimization, not rewriting: add caching layers, optimize database queries, implement CDN, add read replicas, and move heavy operations to background queues. We only recommend rewrites for fundamentally stateful architectures.
How do you do load testing?
We use k6, Locust, or Artillery to simulate realistic traffic patterns at 2-10x your current peak. We identify the breaking point, analyze bottlenecks (usually database or external APIs), and fix them. We then retest to verify improvements.
What causes most scaling issues?
In our experience: N+1 database queries (solved with eager loading and query optimization), lack of caching (solved with Redis), synchronous heavy operations (solved with background queues), and monolithic databases (solved with read replicas and eventually sharding).
