Mark Burgess and Diego Zamboni introduce CFEngine. They describe the challenges regarding web scale - scale, complexity and knowledge - and how CFEngine helps to tackle those challenges with a fundamentally decentralized and knowledge-oriented approach. An example demonstrates how those ideas translate into practice.
Joseph Hall, SaltStack senior engineer, introduces the the remote execution and configuration management system. He describes the tool’s guiding principles: scale, speed and power. Joseph argues that "infrastructure as data" is better than "infrastructure as code". The article finishes with a simple LAMP scenario to demonstrate SaltStack.
This article gives a short introduction to NixOS, a Linux distribution, and to Nix, the package manager on which NixOS is based. These provide a declarative approach to configuration management with many advantages to users, such as strong reproducibility and atomic upgrades and rollbacks.
Michael DeHaan, creator of Ansible, introduces the IT automation system, its guiding goals and the philosophy behind its community. Michael uses a simple but common scenario to demonstrate Ansible.
Once the cultural DevOps transformation is under way, how can teams shipping cloud (or on-premises) applications use the full suite of DevOps technologies to simplify delivery and management at scale? 4
Scripting database objects change-scripts is a risky thing to automate. A better solution needs to be implemented in the shape of Continuous Delivery and DevOps for database.
"In Search of Certainty", written by CFEngine's creator, Mark Burgess, takes us into a journey through physics and biology and how it relates to the information infrastructure realm.
John Kordyback explains why you should and how you can introduce Continuous Delivery into a typical enterprise, where dozens of systems adopted over the years generate massive complexity. 4
Andrew Phillips and Jenkins creator Kohsuke Kawaguchi review state-of-the-art plugins and solutions in the Jenkins ecosystem for achieving efficient, reproducible and secure delivery pipelines.
InfoQ reached out to experienced ops engineers to ask them what is “Immutable Infrastructure”, its borders as well as its benefits and drawbacks, in particular compared to desired state convergence. 1
The second edition of Stephen Nelson-Smith's book "Test-Driven Infrastructure with Chef" describes a testing workflow and tools for writing fully tested infrastructure code
Yaniv Yehuda looks at the challenges involved in automating database deployments and offer suggestions based on Agile and DevOps concepts. 6
