Devops For The Desperate

DevOps for the Desperate is a hands-on, no-nonsense guide for those who land in a DevOps environment and need to get up and running quickly. This book introduces fundamental concepts software developers need to know to flourish in a modern DevOps environment including infrastructure as code, configuration management, security, containerization and orchestration, monitoring and alerting, and troubleshooting. Readers will follow along with hands-on examples to learn how to tackle common DevOps tasks. The book begins with an exploration of DevOps concepts using Vagrant and Ansible to build systems with repeatable and predictable states, including configuring a host with user-based security. Next up is a crash course on containerization, orchestration, and delivery using Docker, Kubernetes, and a CI/CDpipeline. The book concludes with a primer in monitoring and alerting with tips for troubleshootingcommon host and application issues. You'll learn how to: Use Ansible to manage users and groups, and enforce complex passwords Create a security policy for administrative permissions, and automate a host-based firewall Get started with Docker to containerize applications, use Kubernetes for orchestration, and deploycode using a CI/CD pipeline Build a monitoring stack, investigate common metric patterns, and trigger alerts Troubleshoot and analyze common issues and errors found on hosts

Increase profitability, elevate work culture, and exceed productivity goals through DevOps practices. 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, cardholder data breaches, 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 and reliably deploying code into production hundreds, or even thousands, of times per day. Following in the footsteps of The Phoenix Project, The DevOps Handbook shows leaders how to replicate these incredible outcomes, by showing how to integrate Product Management, Development, QA, IT Operations, and Information Security to elevate your company and win in the marketplace.

In the latest novel from national bestselling author Gerry Bartlett, curvaceous vampire Glory St. Clair has to figure how to compete with the wiles of a witchy woman... Just when Glory has her life semi–on track, a woman from her longtime lover Jeremiah Campbell’s past steamrolls into town on a mission to win him back. Normally Glory wouldn’t feel threatened by a mortal with amorous intentions, but Jerry’s ex just happens to be a beautiful voodoo priestess with evil spirits at her beck and call—and a serious lack of conscience when it comes to getting what she wants. And then there’s Glory’s family. After a lifetime of being MIA, Glory’s mom wants to go on a mother-daughter bonding trip to Olympus, home of the gods. And though Glory doesn’t trust her, her mother is offering to help with her pesky voodoo-woman problem. But with no guarantee of a return trip, can Glory dare leave Jerry alone while she visits a place where her less-than-perfect figure won’t be appreciated and time has no meaning? But size and the bonds of time are the least of her worries when love is on the line…
