Here are some of the top DevOps myths.
DevOps replaces Agile
DevOps is absolutely compatible with Agile. In fact, DevOps is the logical continuation of the Agile journey that was started in 2001, because we now know that the real definition of “done” is not when development is done coding. Instead, code is only “done” when it has been fully tested and is operating in production as designed. (Note that Agile is not a prerequisite for adopting DevOps.)
DevOps replaces ITIL
Although some may view DevOps as backlash to ITIL (the IT Infrastructure Library) or ITSM (IT Service Management), DevOps and ITIL are compatible, too. ITIL and ITSM remain the best codifications of the processes that underpin IT Operations, and actually describe many of the capabilities needed in order for IT Operations to support a DevOps-style work stream.
DevOps means NoOps
DevOps is sometimes incorrectly interpreted to be NoOps (i.e., IT operations is entirely eliminated). However, more precisely, DevOps will often put more responsibility on development to do code deployments and maintain service levels. This merely means that development is taking over many of the IT Operations and operations engineering functions.
DevOps is only for open source software
Although many of the DevOps success stories take place in organizations using software such as the LAMP stack (Linux, Apache web server, MySQL database, PHP or Python or Perl), organizations are implementing DevOps patterns using Microsoft .NET, SAP, and even COBOL applications running on mainframes and HP LaserJet firmware.
DevOps is just “infrastructure as code” or automation
While many DevOps patterns require automation, DevOps also requires shared goals and shared pain throughout the IT value stream. This goes far beyond just automation.
DevOps is only for startups and unicorns
DevOps is applicable and relevant to any organization that must increase flow of planned work through development while maintaining quality, reliability, and security for the customer.
