If there were any doubts about DevOps and PaaS being tied to each other, I think the reported growth in the PaaS market should put it to rest.
MarketsandMarkets recently reported that PaaS in 2014 has grown to $1.28 Billion and the expected CAGR is upward of 32 percent.
So the question is what is causing such a huge uptick in PaaS adoption?
The answer is simple – rather than spending all their money on IaaS, a number of enterprise players including banks, telco and even providers of payroll services are recognizing the need for PaaS and experimenting with it.
Don’t get me wrong. This doesn’t mean the end of Data Center or private cloud. It just means that for a number of new apps, these traditional IT shops need new frameworks and auto-scaling, elastic infrastructure to support the app tiers – something that all major PaaS providers deliver but IaaS does not.
As we move forward and enterprise IT adopts cloud and develops DevOps mindset, we will see more and more teams moving to (private or public) PaaS.
What remains to be seen is if they will pay for the platform (Heroku, EngineYard, etc) or go with opensource versions of Cloud Foundry and OpenShift.
