Integration will move up the agenda of enterprise IT leaders in 2017 for one simple reason: digital business calls for the ability to have different applications, data sources, and middleware components talk to each other to deliver digital services and IT capabilities.


  • Enterprise IT leaders will show greater courage and many will indeed “rip and replace” a significant part of existing integration infrastructure to meet digital business integration requirements.
  • Global middleware-as-a-service market is expected to grow by over 35% over the next couple of years, with pure-play iPaaS being a major contributor to market spend.
