The Challenge

  • The app’s user traffic growth was expected to increase dramatically and required the ability to scale up immediately to user demands.
  • Infrastructure costs increase with the growth of application load. Minimizing the monthly run costs when user activity is low was a goal.
  • System redundancies needed to be implemented to limit outages.
  • Simplified deployment process for a modern serverless application was needed. Limit any manual intervention

The Solution

  • Implementing the serverless framework with API Gateway, Lambda, CloudFront, & S3 allows Wattifi to scale easily & manage infrastructure as code.
  • Leveraging a serverless solution allows Wattifi to avoid fixed hourly charges in favor of per web request.
  • The inherent redundancies & scalability of CloudFront, S3, API Gateway, & Lambda, allowed Wattifi to achieve a very high application reliability.
  • Implemented a reliable DevOps deployment model with AWS CodeCommit, CodePipeline & Codebuild.


  • Scalability
    Wattifi is able to instantly scale their application to any user demand with API Gateway and Lambda.
  • Continuous integration
    With low deployment times and eliminated need for manual processes has reduced deployment risks.
  • Cost
    Replacing EC2 with Lambda allowed Wattifi to achieve a cost per app request rather than fixed rates.
