Devops is exciting for developers, and can also be scary. It will change what you need to know and the skills you need in order to succeed. Doing devops requires that you learn new tools and embrace deep cultural changes to the way that you think and work. You'll have to adapt to new processes in the shorter term, while also anticipating long-term organizational changes. Adopting devops means you'll learn to work differently than you have before, alongside other developers and sysadmins who are also making this big shift.
Making the shift
Devops replaces the change control bureaucracy and firefighting that systems administrators are accustomed to with automated continuous deployment and infrastructure as code. The sysadmin becomes an operations engineer, using new tools like Puppet and Chef (and Ansible and Salt and Vagrant and Docker) to design and rapidly spin up standardized, preconfigured systems in a public or private cloud. As a result, wait times go down and reliability goes up.
