Unlock the power of DevOps release management to elevate your software development with early quality checks, testing, automation, and QA integration, reshaping your software delivery life cycle for excellence Key Features Understand the SDLC and the most popular release management models Learn what makes DevOps unique and how CI/CD pipelines enforce good DevOps release management Drive a culture-driven release management initiative in your organization that breaks down silos Purchase of the print or Kindle book includes a free PDF eBook Book Description At the core of software development lies the imperative of swiftly and reliably releasing new features and updates, emphasizing the vital role of release management in the DevOps methodology. Discover how software development teams can elevate their processes by incorporating quality checks and shifting left, moving testing, automation, and QA procedures much earlier into the SDLC. However, release management is still tasked with application monitoring, overseeing infrastructure components, and managing change orders and schedules. This book offers insights into the essence of DevOps Release Management, illuminating its nuances and providing basic strategies for its implementation. You'll explore how CI/CD pipelines enforce good DevOps release management and master techniques to optimize them. You'll also learn how to foster a culture of cross-functional product development that minimizes waste and maximizes value to the customer. By the end of the book, you'll have gained a comprehensive understanding of DevOps release management, its benefits, and practical implementation strategies. Equipped with this knowledge, you'll be able to assess your own development processes and identify areas for improvement, ultimately leading to increased efficiency, collaboration, and value creation.
