Jenkins multiple masters
We are planning to implement a little Jenkins server farm which will continuously build our binaries as code is getting checked in.
- Plan to have around 500-600 odd VMs in this farm
A few questions that arise then are:
1) Should we go with 1 master - multiple slave configuration OR should we have a multiple master-multiple slave configuration? The second seems the obvious choice, however, reading around I found out that resource utilization is much better with the first option.
2) Is there a Jenkins plugin which can facilitate multiple masters - basically so that if a job comes in it is load balanced across the masters which then delegate it to any available slave.
3) Can Jenkins scale upto 500-600 slaves with 1 master alone?
Answer
For your proposed configuration it might be worth going with the commercial product from CloudBees http://www.cloudbees.com/jenkins/enterprise. They will give you support and also have load balanced and high availability plugins which the open source version lacks
