WHAT IS DEVOPS?
DevOps aims for a simple, yet important goal to make IT easier, faster and cheaper, to provide more value faster to the business / consumer / user.
DevOps, a philosophy, culture, and movement that arose from an urgent need for better alignment, collaboration, and empathy between IT Development and IT Operations teams or departments, is now increasingly used to denote precisely the aforementioned key ingredients that constitute the New IT wave.
Enterprise-wide DevOps stands for rethinking traditional IT practices and capabilities, including a product, process, and people perspective. DevOps is the ultimate search for flow in the delivery of IT services.
SOFTWARE DEVELOPMENT METHODOLOGY
WATERFALL
Traditional (1970) structured, rigid software development methodology
Think -Silo’s, software developed as one single project -change is difficult
AGILE
Agile (2001) methodology know for flexibility and fast development of software
Think – Developers develop software super fast but the agility stopped at the door of production
DEVOPS
Devops (2009) collaboration between development and production professionals through all stages of a product or service lifecycle
Think – High-performing teams that meet to metrics for successful digital business models
WHY DEVOPS MATTERS?
Digital Business Models are driving IT transformational Change. Old Waterfall approaches are being abandoned as Enterprises ask the question – What does DevOps mean for my IT organization, are my people ready for DevOps, and do my teams have the right skills to work in an Agile / DevOps environment.
Adopting DevOps concepts and principles requires a deep cultural and organizational change for organizations. Moving from siloed, waterfall driven systems to adopting Agile and Scrum practices first, and DevOps second means changing behavior. Old practices, ways of working make way for new approaches to doing work.
