DevOps as a practice and philosophy includes the communication and teamwork between developers and IT operations. Traditionally, developers and operations are two very different teams who would point fingers when issues would arise with software. DevOps is an attempt to abolish this and has both teams work together. The business result of this is a more stable and reliable software to provide to customers.
Working in a DevOps environment, agility is everything. That next release needs to get into production quickly, so even a minor network issue can hamper speed and efficiency.
