Apps that scale without overpaying
Microservices, serverless and containers designed for your app to grow elegantly from 1K to 1M users.
Building cloud-native applications is not 'uploading your app to AWS'. It's designing from the start to scale elastically, fail gracefully and operate efficiently. We design event-driven, API-first architectures with embedded DevSecOps and observability. We have productive cases in consumer goods, healthcare and education built with this approach (see case studies).
What you get with Caleidos
Event-driven architecture
Decoupled components with SNS/SQS/EventBridge. Resilience to partial failures and ability to scale specific parts in isolation.
Serverless by default
Lambda + API Gateway + DynamoDB when applicable. You pay for actual usage, not idle servers. Instant auto-scaling.
Containers when it matters
EKS or ECS Fargate for workloads requiring granular control or legacy that doesn't easily go serverless.
API-first with governance
Documented, versioned APIs with auth (Cognito or IAM) and rate limiting from day one.

What we get asked the most
Microservices yes or no?
Not by default. For new mid-size apps: well-designed modular monolith usually wins. For apps with clear differentiated scaling requirements per domain or large parallel teams: microservices.
Do you work with Next.js, React, Vue, etc.?
For frontend: React/Next.js most common in our cases, also React Native for mobile. For backend: Node.js, Python (FastAPI), Java (Spring Boot), Go.
How long for a cloud-native MVP?
Functional MVP in production: 8-12 weeks for scoped scope. Complete commercial product (auth, payments, multi-tenant, observability, compliance): 4-6 months.
