Summary ● If you don’t have any CI, start small ● No need for Jenkins: there is plenty of online tools ○ Appcenter, Bitrise, CircleCI, etc. ● Physical devices cheaper than remote options in our case ● But with local Jenkins: ○ Fully configurable ○ OSS and not owned by a single company ○ Well adopted, plenty of plugins, large community ○ More secure (no access from internet)
