In planning, we do requirements definition and architecture design, etc.
And then, We need to prepare a environment to share a information each other development team and operation team.
Project Management Tool
1. Jira
2. Trello
Collaboration Tool
1. Confluence
2. Miro
2. Code
In coding, programmer create source code according to requirements definition.
Version Management System
1. GitHub
2. GitLab
3. Bitbucket
IDE
1. Visual Studio Code
2. IntelliJ IDEA
3. Build
“Build” in DevOps, It pointe to gather source code in one place and to create a software actually to work.
Build is possible to execute manually, but it’s generally used a build automation tool.
Build Automation Tool
1. Maven
2. Gradle
3. Ant
Continuous Integration Tool
1. Jenkins
2. GitLab CI/CD

Container Tool
1. Docker
4. Test
In test process, We actually work a product in test environment and check whether there are bug or not.
Auto Test Framework
1. Selenium
2. JUnit, TestNG
3. Cucumber
Code Quality Analysis Tool
1. SonarQube
5. Deploy
In deploy, We do packaging a developed software and to put source code to production environment that user can use.
In DevOps, generally use CI/CD tool and automate from created source code to this deploy process.
By doing so, We can shorten development cycle and we can efficiently proceed software development.
Artifact Management Tool
1. Artifactory
2. Nexus
Release Pipeline Tool
1. Jenkins
2. GitLab CI/CD
6. Operate
In this process, we need to share circumstances to all of team and smoothly proceed a work.

2. Puppet
3. Chef
Container/Orchestration Tool
1. Kubernetes
2. Docker Swarm
Infrastructure Automation Tool
1. Terraform
7. Feedback / Monitor
After release a software, we continuously gather feedback from a user and reflect feedback in a next development.
At first glance, Monitor and Feedback are understood a cause of delay a development pace, but in the long run, it’s important process to improve development efficiency.
Operation / Infrastructure Monitor Tool
1. Nagios
2. Zabbix
Log Management Tool
1. Splunk
2. ELK Stack(Elasticsearch, Logstash, Kibana)
Performance Monitor Tool
1. New Relic
2. AppDynamics
