Distributed networks
The future will be even more complicated. There is no one single model for applications and no more private networks. Depending upon the application you will need to communicate with clouds, data centers, devices, mobiles, IoT. etc. Roaming between different access networks with different Quality of Service. With bandwidth becoming a very limited resources with billions of new connected devices. And many devices, IoT and applications will communicate directly peer-2-peer without any cloud connection. Why should a key app to your car have to communicate with a cloud somewhere? It would only open for Man-in-the-Middle attacks, DDoS failures, etc.  as well as require unnecessary bandwidth usage.

Security can no longer be peripheral as pointed out here. It must be application, user and situation dependent. And asynchronous to provide reliable transport mechanisms. 

This all means new architectures and methods, that will vary between application types. And yet it has to be simple to develop, implement and maintain, otherwise it will not be used. An open field for innovation and startups like apptimate.io.

Time for the cloud-DMZ?
The concept of a dynamic cloud perimeter is very appealing when faced with mobility and hybrid cloud.  Create the cloud-DMZ once and have all access go through it regardless of where the users, enterprise apps and data lie.  Better yet if the "on-prem" components can effectively take the enterprise infrastructure off the Internet completely and the cloud-DMZ becomes the new LAN.

Unfortunately, the idea that enterprises can "extend-the-perimeter" by establishing trust with user and devices doesn't work in the new outside-in world where all users are accessing internal company data and application from the Internet.  With exploits like the recent StageFright, the reality is we can never be sure that trust, once established, has not been compromised.
