Reducing product costs by migrating to Node.js

  • Saving money on Cloud by handling more requests in a single thread.


Lower costs due to AWS DynamoDB single-table design

Proper understanding of cloud services is crucial for implementing efficient cloud native solutions.
  • Implementing an AWS DynamoDB single-table design correctly and understanding data access patterns thoroughly.
  • The infrastructure part and the application part done by the same team or in close collaboration with the DevOps team.


Business logic and infrastructure using AWS CDK

  • Giving developers operational responsibilities to improve understanding of the services they use allowing them to enhance the performance at the design and infrastructure level.
  • One team using the same set of skills to work on both business logic and infrastructure by leveraging TypeScript, Node.js and AWS CDK.
