Serverless Architecture

Pay for traffic, not idle servers.

Why keep servers running and billing at 3am when nobody's using them? We build serverless on AWS Lambda, Azure Functions, Cloud Run, and event-driven patterns — no infrastructure to babysit, automatic scale, and a bill that tracks real usage.

Less to run, more to ship

The best server is the one you never manage

Serverless trades undifferentiated heavy lifting for focus — no patching, no scaling, no idle bill. For the right workloads, it's the fastest, cheapest way to ship.

No servers to babysit

No instances to patch, scale, or wake up at 3am for. The provider runs the infrastructure, so your team builds features instead of maintaining fleets.

Scales from zero to millions

Functions scale out automatically with demand and back down to nothing when idle — absorbing a traffic spike without any capacity planning.

Pay only for what runs

Billing is per request and per millisecond of execution. No traffic means no bill — eliminating the idle spend that quietly inflates server-based costs.

Event-driven by design

We wire functions to queues, streams, schedules, and event buses with Step Functions orchestration — so even complex workflows stay reliable and observable.

What you get

A system that runs itself

Event-driven, codified, and observable — with cold starts tuned and costs visible, so it's production-ready, not a proof of concept.

  • A serverless application defined entirely as Infrastructure as Code
  • An event-driven architecture diagram and design
  • Functions on AWS Lambda / Azure Functions / Cloud Run
  • Orchestration with Step Functions or Durable Functions where needed
  • Cold-start optimization and a performance benchmark report
  • Observability, tracing, and a cost-monitoring dashboard

Design to launch

How we build serverless systems

  1. 1

    Architecture & event design

    We map your events, triggers, and data flows, and design a serverless architecture sized to your latency and concurrency needs.

  2. 2

    Function & event wiring

    Functions built and wired to queues, streams, schedules, and event buses, defined as IaC for repeatable deploys.

  3. 3

    Performance & cold-start tuning

    Benchmarking and optimization — provisioned concurrency, lean bundles, and runtime tuning where latency matters.

  4. 4

    Observability & launch

    Distributed tracing, cost dashboards, and alerting wired in, then deployed with a clean handover to your team.

Serverless, in production

Cadence Events: a spiky ticketing platform that paid for idle servers

An event-ticketing company ran always-on servers sized for rare on-sale spikes — expensive most of the time, still strained at peak. We re-architected it serverless and event-driven.

Annual savings

We paid for fleets of servers that sat idle between on-sales, then still sweated every big drop. Going serverless cut our compute bill by nearly three-quarters, absorbed our biggest on-sale without us touching a thing, and freed the team from server babysitting entirely.

Straight answers

Serverless architecture questions

What is serverless architecture?

Serverless architecture runs your code in managed, event-driven functions (like AWS Lambda or Azure Functions) and managed services, so there are no servers to provision, patch, or scale. The cloud provider runs and scales the code automatically, and you pay only for actual execution — not for idle capacity.

When is serverless the right choice?

Serverless shines for event-driven workloads, APIs with variable or spiky traffic, scheduled jobs, stream and file processing, and asynchronous tasks. It's less suited to long-running, steady-high-throughput, or ultra-low-latency workloads — we assess your traffic and latency profile before recommending it.

How do you handle cold starts in serverless?

We minimize cold-start impact with provisioned concurrency for latency-sensitive paths, lean runtimes and small deployment bundles, efficient language choices, and keeping functions warm where it matters — so users get consistent response times without paying to run idle servers.

Is serverless actually cheaper?

For variable and event-driven workloads, usually yes — you pay per request and per millisecond of execution instead of for always-on servers, which eliminates idle spend. For constant high-volume workloads the math can flip, so we model your costs honestly before committing to the pattern.

Can you build complex workflows with serverless?

Yes. We orchestrate multi-step, stateful workflows with AWS Step Functions, Azure Durable Functions, and event buses (EventBridge, Pub/Sub), so even complex business processes run reliably in a serverless model with retries, error handling, and full observability.

Stop paying for idle servers. Go serverless where it counts.
