DevOps is about principles, practices, and creating a collaborative environment that improves software delivery and increases business value. It focuses on people and culture to improve collaboration between development and operations groups.
DevOps is not:
• A role, person, or enterprise
• Something only a system administrator can do
• Something only developers can do
• Writing Chef and Puppet scripts
• Tools
The goal of DevOps is to create, operate and manage complex systems with a culture of continuous improvement across all components in the product and service delivery. This includes:
• Improved deployment frequency
• Faster time to market
• Continuous integration
• Continuous delivery
• Infrastructure automation
• Lower failure rates of new releases
• Faster recovery time from crashes or failures
Challenges in adoption of DevOps
Drawing from my experience in DevOps implementation, the top key challenges in adopting DevOps across large enterprises are:
Resistance to change:
Transitioning to DevOps involves cultural shifts, process changes, and new tool adoption. Teams may resist changing established processes and roles.
Absence of cross-functional teams: Silos between development, operations, and other departments can impede collaboration and slow down workflows.
Leadership support: Lack of support from leadership leads to difficulty in initiating changes.
