DevOps Solutions
DevOps is the blending of tasks performed by a company’s application development and systems operations teams. The term DevOps is being used in several ways. In its most broad meaning, DevOps is an operational philosophy that promotes better communication between development and operations as more elements of operations become programmable. In its most narrow interpretation, DevOps describes the part of an organization’s information technology (IT) team that creates and maintains infrastructure. The term may also be used to describe a team of software engineers who strategically look at the entire software delivery chain, overseeing shared services and championing the use of new development tools and best practices.
DevOps Features
Ansible for DevOps
Ansible has rapidly become one of the most popular IT automation tools in the world. We’ve seen the open source community expand from the beginning of the project in early 2012 to over 1200 individual contributors today. Ansible’s modular architecture and broad applicability to a variety of automation and orchestration problems created a perfect storm for hundreds of thousands of users worldwide.
Ansible is a general purpose IT automation platform, and it can be used for a variety of purposes. From configuration management: enforcing declared state across your infrastructure, to procedural application deployment, to broad multi-component and multi-system orchestration of complicated interconnected systems.
Chef DevOps Deployment
Treating infrastructure as code refers to writing code, via any descriptive language, to manage server provisioning and configuration process in addition to deployment of actual application code. It involves adopting automated testing and related practices that are already used in modern application development, such as version control, integration testing, small deployments, use of design patterns etc. One of the popular frameworks for managing infrastructure provisioning and configuration is Chef. It provides an extensive library of primitives for managing every resource that is used in the process of building and maintaining web infrastructure.
Docker
Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.
Jenkins and Build Automation
Jenkins is a software that allows continuous integration. Jenkins will be installed on a server where the central build will take place. The following flowchart demonstrates a very simple workflow of how Jenkins works. As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project. Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Mac OS X and other Unix-like operating systems.
