scale-to-zero apps
Applications that scale on demand and idle to nothing
We architect at the application layer for the cloud's native primitives: functions that spin up per request, managed databases and queues instead of servers to babysit, and event-driven flows so the system scales with traffic and costs nothing while it waits.

Cloud-native application design, not just deployment
Cloud-native is an architecture decision, made in the code, before any infrastructure is provisioned. We design applications as composable functions and managed services — event-driven where it fits, stateless by default, and built around the platform's building blocks — so the app absorbs a traffic spike, scales to zero when quiet, and bills for what it runs rather than what it reserves.
Applications architected as functions and managed services — event-driven, scale-to-zero, and priced by execution rather than idle server time.
What you get
Scaling you don't manage
Functions and managed services scale up with demand and down to zero on their own, so a traffic spike is absorbed automatically instead of paging someone to add capacity.
Cost that follows usage
Paying per execution rather than per idle server means a quiet app costs almost nothing, and a busy one costs in proportion to the work it actually did.
Less to operate and patch
Managed databases, queues, and runtimes take server maintenance off your team's plate, so effort goes to the application instead of the machines under it.
Core capabilities
How the application scales itself
Serverless application design
Functions and stateless services designed around the platform's execution model so the app scales per request and idles to zero.
Managed data & messaging
Managed databases, queues, and object storage chosen so there are no servers to patch and state is handled by the platform.
Event-driven flows
Events, triggers, and asynchronous processing so work happens in response to activity rather than a polling loop or a warm server.
Cold-start & cost tuning
Function sizing, concurrency, and cold-start handling tuned so the serverless model stays fast and economical at real load.
The rollout
From traffic shape to a tuned, scaling system
Week 1
Map the traffic shape
Spiky, steady, or idle most of the time: the workload's real usage pattern gets mapped before a single function is written.
Week 2
Decompose into functions
The application is broken into event-driven functions and triggers, each scoped to one job.
Week 3
Wire managed data & queues
Managed databases and queues replace the servers your team would otherwise size and patch.
Week 4
Load-test and tune
The system is tested under real traffic and cold starts are tuned wherever latency actually matters.
How we work
From decomposition to tuned under real load
Decompose the app
Break the application into functions and managed services that map to the cloud's execution and storage primitives.
Design the events
Define the triggers and async flows so processing follows activity instead of running on idle servers.
Build on managed services
Implement against managed databases, queues, and storage so there's no infrastructure to babysit.
Tune for load & cost
Address cold starts, concurrency, and function sizing so the app stays fast and cheap under real traffic.
Under the hood
Three pieces, working together as one architecture
The application is decomposed into event-driven functions, each triggered by the request, upload, or queue message that actually needs it, instead of a monolith listening for everything at once.
- Event-driven functions
- Scoped triggers
- One job per function
Benefits
No server sized for the bad week
No capacity reserved for a spike that happens once a month. The platform absorbs it when it comes.
The bill tracks real usage
A quiet night costs close to nothing; a busy month costs in proportion to what it actually processed.
Spikes absorbed automatically
A launch or a promotion scales without anyone getting paged at 2am.
Cold starts tuned before they're a complaint
Function sizing and keep-warm strategies are addressed deliberately, long before production finds them.
Patching becomes the platform's job
Managed runtimes and databases take server maintenance off your team's plate.
An honest call if the workload changes
If traffic becomes steady and high-throughput, we'll say when containers would serve you better.
Selected work
Workloads built for their own traffic shape
Deliverables
What lands in your repo
A working app, plus the event and data architecture and the cost profile that let your team run it after we leave.
Cloud-native application
The app built as functions and managed services, event-driven and designed to scale to zero.
Event & data architecture
The triggers, queues, and managed data stores that carry the application's workload.
Cost & performance profile
Cold-start, concurrency, and cost tuning documented so the serverless model holds at scale.
Industry expertise
Where the traffic idles, then spikes
E-commerce & retail
Checkout and order flows that idle overnight and spike on a promotion: the textbook case for paying per execution instead of per reserved instance.
Media & publishing
Bursty traffic around a story or a drop, absorbed automatically instead of over-provisioned for a peak that comes twice a year.
Financial services
Event-driven processing (payments, settlements, statements) where each message triggers exactly the function it needs and nothing sits idle.
Logistics & distribution
Order and tracking pipelines that scale for month-end volume and cost close to nothing at 2am, when nothing is moving.
SaaS & startups
New products whose traffic is unknown, where scale-to-zero economics mean you're not paying for load you don't have yet.
Events & ticketing
The on-sale spike that would crush a fixed cluster, absorbed by a platform that scales to it and back down after.
Got a workload that idles at night and spikes at month-end?
Tell us the workload and its traffic shape. We'll map a serverless architecture that fits it and show you the cost profile before you commit, instead of after the first invoice.
Why choose us
Architecture that earns the pay-per-execution pitch
Built on the cloud's native primitives
Functions, managed databases, and managed queues do the work instead of a server you have to size, patch, and babysit.
You pay for execution instead of idle time
A quiet night costs close to nothing and a busy month costs in proportion to the orders it actually processed, with no reserved capacity sitting idle.
Scales without a 2am page
A traffic spike is absorbed by the platform automatically, so a launch or a promotion doesn't turn into an incident.
No servers for your team to patch
Managed databases, queues, and runtimes take server maintenance off your plate, so effort goes into the application instead of the machines under it.
Cold starts tuned, never ignored
Function sizing, concurrency, and keep-warm strategies are addressed deliberately wherever latency actually matters.
Honest when serverless isn't the fit
Steady, high-throughput workloads are sometimes better served by containers, and we say so before you commit to the wrong model.
Why work with Flaidex

03
Cost profile shown before you commit
We model what the workload will actually cost under serverless pricing before you approve the rebuild, instead of after the first invoice.
04
Documentation your engineers keep
Clear, maintainable docs of the functions, triggers, and data flow, written for your team to own and extend after we leave.
05
Built on your cloud, no new platform
We build on the managed services your provider already offers, with nothing proprietary to adopt or get locked into.
06
Plain answers on serverless vs. containers
If your workload is steady and high-throughput, we'll tell you when a container-based approach serves you better.
Questions
What teams ask before they go serverless
Q01How is cloud-native development different from DevOps or containerization?
Cloud-native is an application-architecture decision made in the code: designing the app as functions and managed services that use the cloud's native primitives, so it scales per request and idles to zero. DevOps is the operational practice of automating deployment and running environments; containerization is a packaging choice. This service is about how the application itself is structured, not how it's deployed or packaged — those are separate, complementary concerns.
Q02What does 'scale to zero' actually mean for our costs?
It means that when no one is using the app, it consumes no compute and therefore costs almost nothing, unlike a traditional server that bills whether or not it's handling requests. You pay per execution, so cost tracks real usage: near-zero when quiet, proportional when busy. For workloads with uneven or bursty traffic, that pricing model is often dramatically cheaper than reserving always-on capacity.
Q03What are cold starts, and do they hurt performance?
A cold start is the brief delay when a function spins up after being idle. For most workloads it's negligible, but for latency-sensitive paths it matters, so we tune for it — sizing functions appropriately, managing concurrency, and using provisioned concurrency or keep-warm strategies where a path genuinely can't tolerate the delay. We address cold starts deliberately rather than letting them surprise users.
Q04Is serverless right for every application?
No. Serverless shines for event-driven, bursty, or unevenly-loaded workloads where scaling and idle cost matter. Steady, high-throughput, or long-running workloads can be better served by containers or provisioned compute. We assess the workload's traffic shape and processing pattern before committing, and we're candid when a serverless model isn't the economical or performant fit.
Q05How do you handle state in a serverless architecture?
By keeping the functions stateless and pushing state into managed services — databases, queues, object storage, and caches the platform operates. That separation is what lets functions scale freely, since any instance can handle any request without local state. It also removes servers you'd otherwise have to patch and maintain, which is a large part of the operational saving.
