Also, the way people and teams worked have changed drastically in recent years with the advent of new philosophies such as DevOps and methodologies like Agile.

Unlike before, different teams have started working together and there is more and more automation from application development to deployment. vagrant and docker made developers life so easy by  reducing the time to setup, test development environments. Cloud computing has drastically changed the way how servers are provisioned. You don’t need to wait for days to get a server provisioned for your application deployment. With few clicks, you will have your server ready for deployment. The process gets more easy by writing automation scripts for server provisioning and configuration. One such example is python boto library. Using boto sdk you can automate AWS server provisioning.
