Infrastructure that costs what it uses, not what it might.
Serverless means you build and run applications without thinking about servers: nothing to provision, nothing to patch, capacity that follows demand, and a bill that follows execution rather than uptime.
FUEiNT Technologies is a software studio in Coimbatore, India, building serverless applications on AWS since 2014 — Lambda, API Gateway, DynamoDB, Cognito, S3 and CloudFront, defined in code with SAM or CDK.
What we actually build.
The full AWS serverless suite, used where each part earns its place. Nothing here is on the list because it sounds modern.
Run code without provisioning or managing servers. You pay only for the compute time you consume, which is what changes the economics of a spiky workload.
A fully managed front door for creating, publishing, maintaining, monitoring and securing APIs at any scale.
A key-value and document database delivering single-digit millisecond performance at any scale — provided the access patterns are designed first, which is the part most teams skip.
Sign-up, sign-in and access control, so you are not writing and then defending an authentication system of your own.
Secure, durable, scalable object storage with content delivered from the edge closest to the user.
AWS SAM or CDK, so every environment is reproducible and a rollback is a deploy rather than an act of memory.
How a serverless engagement runs.
What runs today, when it spikes, and what it costs. Nothing moves before there is a picture of what is being moved.
The heaviest and spikiest thing goes first, because that is where serverless pays back fastest and proves the pattern.
Functions, tables, queues and permissions defined in SAM or CDK — never clicked into a console where the next person cannot find them.
Logs, traces and alarms in place before traffic, so the first surprise is visible rather than reported by a customer.
You get the view that explains every line of the invoice, in the account that receives it.
- Your current architecture, however roughly drawn.
- A recent AWS bill, or your hosting invoice if you are not on AWS yet.
- The workload that spikes, and roughly when.
- Compliance or data-residency constraints, if any exist.
Questions we are actually asked.
What does serverless actually mean here?
Serverless architecture lets you build and run applications and services without thinking about servers — AWS handles the infrastructure management. There is no software or runtime for you to install, maintain or administer.
Serverless or a normal EC2 setup?
On cost, serverless is pay-per-use and often cheaper where traditional hosting charges a fixed monthly cost including idle time. On scalability, serverless is automatic and instant where EC2 is manual or slow to auto-scale. On maintenance, serverless is effectively zero where a server means OS updates and security patches. Steady, predictable, always-on load is the case where a server still wins.
Can you migrate an application we already run?
Usually in pieces. The heaviest and spikiest workloads move first, and the rest follows once the pattern has proven itself under real traffic.
Which languages do you write Lambdas in?
Node.js and Python are our defaults, and both are first-class runtimes on Lambda.
Whose AWS account does this live in?
Yours, wherever you have one — so the bill, the logs and the data are yours from the first deploy, and the infrastructure-as-code repository is yours with them.
The work either side of this one.
Send us the invoice you cannot explain.
A cost and load model of what you run today is the first thing we produce, before anything is moved. Two sentences is enough to start it.
