More than ever, the effective management of technology is critical for business competitiveness. For decades, technology leaders have struggled to balance agility, reliability, and security. The consequences of failure have never been greater-whether it's the healthcare.gov debacle, the Target cardholder data breach, or missing the boat with Big Data in the cloud.
And yet, high performers using DevOps principles, such as Google, Amazon, Facebook, Etsy, and Netflix, are routinely deploying code into production hundreds, or even thousands, of times per day, while providing world-class agility, reliability, and security. In contrast, most organizations struggle to do releases every nine months. By studying over 14,000 IT professionals worldwide, the authors have observed that high-performing organizations are 2.5 times more likely than their peers to exceed profitability, market share, and productivity goals.
The DevOps Handbook shows leaders how to replicate these incredible outcomes, describing what is required from all parts of the technology organization. Product Management, Development, Test, IT Operations, and Information Security working together can create the cultural norms and the technical practices necessary to maximize organizational learning, increase employee satisfaction, and win in the marketplace.
