Concourse vs Hudson: What are the differences?
What is Concourse? Pipeline-based CI system written in Go. Concourse's principles reduce the risk of switching to and from Concourse, by encouraging practices that decouple your project from your CI's little details, and keeping all configuration in declarative files that can be checked into version control.
What is Hudson? Extensible continuous Integration Server. Hudson monitors the execution of repeated jobs, such as building a software project or jobs run by cron. Among those things, currently Hudson focuses on the following two jobs:
1.Building/testing software projects continuously, just like CruiseControl or DamageControl
2.Monitoring executions of externally-run jobs.
Concourse and Hudson can be primarily classified as "Continuous Integration" tools.
