App integration

• Connecting cloud applications and workflows so they can communicate and/or exchange data
• Key services

The Problem

• diagram
• Scenario
  • App A - crawls data
  • App B - gets the crawled data & transforms it
  • You want to ensure these apps are modular, but they must work together
  • You can have an API (could be built with API Gateway or AppSync), and App A could send a request to this API once it’s done crawling
• The problems
  • different applications running on top of different instances/services don’t necessarily bring their own communication APIs
  • extra cost (we have to build and maintain the extra api)
  • if u have other applications that does same thing, same solution must be re-implemented (copied) many times
  • Connectivity may be problematic
