  20. 20. Companies Ecosystems (Devs)Ecosystem #2: SOA + ESB Style
  21. 21. Developer PerspectiveSOA + ESB Style for Developers Encourage reutilization Standardize and hide communications between different applications If the services are well documented, decoupled and well focused everything is easy You need to know how to expose legacy apps if they dont have an exposed interface The ESB will deal with different protocols of communication
  22. 22. Developer Perspective (Common Issues)Common Issues Developers says that they like re-utilization We all prefer new or known technologies We all prefer using and researching new stuff We dont like to review or modify old code 99.999999% of the times companies have legacy systems DEAL WITH IT!
