This document discusses strategies for building scalable architectures on the cloud as a startup. It recommends adopting a serverless approach using microservices and cloud services. The document outlines how serverless architectures provide better scalability, efficiency and flexibility compared to managed servers. It provides examples of AWS serverless services that can be assembled to build applications, such as Lambda, API Gateway, DynamoDB. The conclusion recommends focusing on assembling existing microservices rather than building proprietary ones, using serverless solutions for faster development, and migrating applications to the cloud for scale.

Conclusion / Tips
ASSEMBLE MICROSERVICES
GO SERVERLESS
SCALE UNI-CLOUD
“Focus on unique assembly of existing web microservices (eg.AI services)
versus building and maintaining your own propietary web microservices.”
APPLICATION
STACK
“Focus on serverless solutions as much more effective use of your limited
resources and faster time to market. Decouple your microservice as much
as possible for scale, using event-driven design with queues or streams.”
“Focus on migratbility of your applications (eg. standards / containers)
versus going down the route of a multi-cloud or self-managed strategy.”
