Too Long; Didn't Read
As a solo entrepreneur I cannot manage a server myself. PaaS comes in as a life saver. Since I started hosting my apps on Google App Engine I saved time and money, but the best part is: my app is secure and scalable without having to lift a finger. It's like all of Google is working for me to host secure and scale my apps. So if you are like me, a solo engineer or even a small team still hosting your app on server instances, I bet its only a matter of time.
