The classic mistake: AWS everything from day one
Bill shock
Your cloud bill doubled in six months, nobody can explain every line item, and the Kubernetes cluster set up "for future scale" is serving a few hundred users.
AWS has a service for everything. That is its strength for large organisations with dedicated infrastructure teams. For a startup with two engineers building an MVP, it is a complexity trap. You spend two weeks configuring IAM roles, VPCs, and security groups before writing a line of product code.
The right infrastructure for a startup is the simplest infrastructure that meets the current requirements, not the infrastructure that will meet requirements three years from now.
A sane starting point
PaaS for early stage (pre-product-market fit)
Railway, Render, or Fly.io deploy your application from a Dockerfile with minimal configuration. Managed Postgres, Redis, and object storage are one click away. You pay per use. No IAM, no VPC, no load balancer config. This is the right default until you have real traffic and a reason to optimise.
AWS/GCP/Azure at growth stage
Once you are past product-market fit and have traffic that makes per-request PaaS pricing painful, moving to EC2/ECS or GKE with managed RDS/Cloud SQL is the right step. The migration is not trivial, but the cost savings at scale justify it.
The exception: compliance requirements
If your product handles healthcare data (HIPAA), financial data (PCI), or European user data (GDPR with specific residency requirements), you may need AWS/GCP from the start to meet certification requirements.
Cloud bill growing faster than your users?
Get a free consultationWhat every production deployment needs
Regardless of infrastructure provider, a production deployment needs: a deployment pipeline that runs tests before deploying, environment variable management that keeps secrets out of the codebase, automated database backups with tested restore procedures, basic observability (error tracking, uptime monitoring, log aggregation), and a rollback path for bad deploys.
These are not optional. A startup without database backups is not running lean: it is one corrupted table from losing everything.
Cut cloud costs without slowing down: a FinOps checklist
FinOps is not about the smallest possible bill: it is about getting value from every dollar. These six habits catch most waste.
Tag every resource
Label by product, environment, and owner so every line on the bill has a name next to it.
Set budget alerts
Get an alert when spend passes 50%, 80%, and 100% of the monthly budget, not when the invoice arrives.
Switch off what is idle
Staging and preview environments rarely need to run overnight or at weekends.
Commit only to your baseline
Savings plans or reserved capacity for steady load; on-demand for everything else.
Watch serverless and AI usage
Functions and model calls are cheap per request and expensive at scale. Monitor them daily.
Review monthly
A 30-minute monthly review with engineering and finance keeps costs from drifting.
Key takeaway
The goal is not the smallest bill. It is knowing what every dollar buys and switching off what buys nothing.
