This article mainly explains "what are the advantages of DevOps". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the advantages of DevOps".

DevOps (a combination of Development and Operations) is a group of processes, methods, and systems that facilitate communication, collaboration, and integration among development (application / software engineering), technology operations, and quality assurance (QA) departments. It is a culture, sport, or practice that emphasizes communication and cooperation between "software developers (Dev)" and "IT operation and maintenance technicians (Ops)". Build, test, and release software more quickly, frequently, and reliably by automating the process of "software delivery" and "architecture change".

Benefits and value of Devops

According to the 2016 DevOps New Trends Survey, 74% of companies are trying to accept DevOps, so what are the benefits and value of Devops?

Code submission is directly triggered: eliminate waiting time, quickly feedback each change corresponding to a delivery pipeline: make problem location and debugging easy, the full development process is efficient and automated: stable, fast, delivery results are predictable and continuously automated regression testing: improve delivery quality facilities sharing and provide on demand: maximize resource utilization

As can be seen above, the benefits of DevOps are based more on continuous deployment and delivery, which is for business and products. DevOps begins with the acceptance of DevOps culture and technology methodology, which is a set of processes and methods for inter-departmental communication and cooperation, which helps to improve the company's organizational culture and enhance employees' sense of participation.

Devops and continuous Integration

DevOps is a complete workflow for IT operation and maintenance, which optimizes all aspects of program development, testing, system operation and maintenance based on IT automation, continuous integration (CI) and continuous deployment (CD).

Throughout the technical materials of various DevOps practice companies, the most comprehensive and classic is the technical key points of DevOps Tools mentioned in flickr's 10 + deploys per day best practices:

1.Automated infrastructure (Automation, Integration between Systems) 2.shared version control (SVN shared Source) 3.one step build and deploy (continuous build and deployment) 4.feature flags (backbone Development) 5.Shared metrics 6.IRC and IM robots (Information Integration)

The above technical points run through the line of continuous integration / deployment, backbone development is the premise of continuous integration, automation and centralized management around the code are necessary conditions for the implementation of continuous integration. There is no doubt that DevOps is an extension of the idea of continuous integration, and continuous integration / deployment is the technical core of DevOps. Without automated testing and continuous integration / deployment, DevOps is a castle in the air.

Technology Stack and tool chain of DevOps

Everything is Code,DevOps also integrates continuous integration, continuous delivery, user feedback and system optimization through the technical tool chain. Elasticbox collates 60 + open source tools and categories, including version control & collaborative development tools, automated build and test tools, continuous integration & delivery tools, deployment tools, maintenance tools, monitoring, warning & analysis tools, etc., and complements some domestic services that enable you to better implement DevOps workflows.

Version control & collaborative development: GitHub, GitLab, BitBucket, SubVersion, Coding, Bazaar automated build and test: Apache Ant, Maven, Selenium, PyUnit, QUnit, JMeter, Gradle, PHPUnit continuous integration & delivery: Jenkins, Capistrano, BuildBot, Fabric, Tinderbox, Travis CI, flow.ci, Continuum, LuntBuild, CruiseControl, Integrity, Gump, Go container platform: Docker, Rocket, Ubuntu (LXC), third-party vendors such as (AWS/ Aliyun) configuration management: Chef, Puppet, CFengine, Bash, Bash, Rudder, Rudder Ansible micro-service platform: OpenShift, Cloud Foundry, Kubernetes, Mesosphere service activation: Puppet, Docker Swarm, Vagrant, Powershell, OpenStack Heat log management: Logstash, CollectD, StatsD monitoring Warning & Analysis: Nagios, Ganglia, Sensu, zabbix, ICINGA, Graphite, Kibana

DevOps = Culture + Tools

If you want to deploy DevOps throughout the business, you need not only soft requirements, that is, top-down cultivation of DevOps culture to explore, but also hard tool chain requirements in order to achieve higher quality software delivery.
