Complex Tablet Solution

Project Description

Customer was looking for tablet solution to support complex workflows and functionalities, with key requirements like

  • Complex workflows
  • Including payment functionality
  • All functionality must work on- and offline
  • Only a subset of data can be stored on tablet
  • Data input is coming from several subsystems, must be merged to be usable
  • Data output must be sent back to subsystems
  • Subsystems cannot handle data exceptions themselves
  • Communication with subsystems is sensitive
  • System must be scalable for high load and worldwide rollout

Tablet Solution


MCON was designing a infrastructure based on Amazon Web Services including:

  • Authentication using Amazon Cognito
  • Middle layer for complex communication and information commissioning, based on Java
  • Highly secured middle layer, no direct connection from tablets to middle layer
  • Communication with tablets through messaging services only (Amazon SNS, Amazon SQS), large data to be transferred encrypted by Amazon S3 buckets


Amazon Web Services

  • Amazon Cognito
  • Amazon SNS
