System Engineering / Scalability

Scalability Engineering

Products rarely fail at launch — they fail when growth arrives and one part of the system can't keep up. We find where your architecture will break first, then design and implement the changes — stateless services, caching, queues, autoscaling, and data-layer scaling — that let it grow predictably.

This Is For You If...

  • Traffic is growing and response times rise at peak hours

  • A launch, campaign, or new customer will multiply your load soon

  • Your app runs on one server and you're not sure what happens with two

  • Infrastructure costs grow faster than your users



Which Area Matches Your Problem?

Ask Yourself

Points Toward

Do you know where the system breaks under load?

Load Testing & Capacity Planning

Does the app keep state on the server?

Horizontal Scaling

Is the same data fetched again and again?

Caching

Do slow tasks run inside user requests?

Queues & Background Processing



Scalability Services We Offer

Load Testing & Capacity Planning

We simulate realistic traffic with k6, Locust, or JMeter to find the first bottleneck and the load at which it appears.

Horizontal Scaling

Making services stateless, moving sessions and files out of the server, and adding load balancing and autoscaling.

Caching

Redis, CDN, and application caching with invalidation rules that keep data correct.

Queues & Background Processing

Moving slow work — emails, reports, AI calls, imports — to queues and workers so requests stay fast.



What We Need From You

What to Share

Why It Helps

Current traffic and growth expectations

Defines the scale to design for

Architecture overview and hosting

Shows what can scale and what can't

Monitoring data at peak

Points to the current bottleneck

Budget constraints

Keeps the design cost-effective



Common Mistakes to Avoid

Instinct

Why It Doesn't Help

Do This Instead

Rewriting as microservices to scale

Adds complexity without fixing the actual bottleneck

Find the bottleneck first with load tests

Buying bigger servers repeatedly

Costs rise and there's always a ceiling

Make the app horizontally scalable

Caching without an invalidation plan

Users see stale or wrong data

Define when and how each cache is refreshed

Ignoring the database

It's usually the first limit

Plan Database Scaling alongside the app



How It Works

1. Share goals

Tell us your expected growth and current pain

2. We load test

We find where and when the system breaks

3. We design changes

Prioritized by impact and effort

4. We implement

Changes rolled out and re-tested under load

5. We hand over

Capacity plan, dashboards, and runbooks



Why Codersarts

We base every scaling change on measured bottlenecks, not assumptions, and choose the simplest change that meets your growth. You get a system that scales and a team that understands why.



Turnaround Time

A load test and scaling plan is typically delivered within a week. Implementation is scoped from the plan.



FAQ

Do we need Kubernetes to scale?

Not necessarily. Managed autoscaling is often enough; see Kubernetes when it is.

Can you scale an AI-built app?

Yes — often after a rescue; see AI App Rescue.

How is this different from performance work?

Performance makes one request faster; scalability keeps it fast as load grows. See Performance Engineering.

Is our project kept confidential?

Yes. Your data, code, and results stay confidential, and an NDA is available on request.
