The new culture of software development, explained by a 30-year industry veteran.
Over the last decade, more and more companies have adopted a new approach to software development called Dev Ops. But few people seem to understand what Dev Ops is—or how they might fit into a Dev Ops environment.
Dev Ops Overture answers these questions. It begins with an overview of what software development methodologies came before Dev Ops and of the problems associated with those systems. It then explains what Dev Ops is and how it works to address these problems. Finally, it offers advice to anyone who wants to position themselves for a career in Dev Ops and warns of common pitfalls to avoid.
Maybe your company has adopted Dev Ops, and you need to adjust to an Agile culture. Or perhaps your company hasn’t adopted Dev Ops, and you want to either advocate for the change or to position yourself to switch to a company that has. Or maybe you want to become conversant in Dev Ops practices. Either way, Dev Ops Overture is for you.
Shawn D. Doyle is a founder and CEO of Release TEAM, Inc., a Dev Ops Consulting Firm, established in 1999. After serving in the US Army and Desert Storm, he has amassed nearly 30 years of software delivery experience, having worked with companies from midsized to Fortune 100 to solve their business-critical challenges. Shawn lives with his wife and three dogs in Colorado.
Software is everywhere. Dev Ops makes better software. Here is where you start.
