group suggestions performed a significant function in setting the objectives for Puppet 5’s
launch, having helped the builders with figuring out and defining sure
patterns, corresponding to:
- Completely different model numbers
throughout elements have been an enormous supply of confusion - There was numerous chaos when
it got here to combining elements to get a working set up in addition to the place
every part would match - Since each Facter 3 and
PuppetDB 3 seamlessly rolled into PC1, guaranteeing a brand new Puppet Assortment for
each main launch didn’t make a lot sense
makers ensured that one essential side didn’t get affected: Modules that labored on Puppet 4 will work
unchanged beneath Puppet 5.

or$surroundings
, it received’t set up a brand new file in
both location or take away$hieradata
.
Efficiency boosts
enhancements and new options have contributed to ushering efficiency boosts
in numerous features. The runtimes of Puppet 5 agent have decreased by 30% at
equal hundreds (that’s, from a median of 8 seconds to five.5 seconds). In
addition CPU utilization of Puppet 5 server has decreased by no less than 20% as
in comparison with Puppet 4 in all situations, whereas the CPU utilization for Puppet 5
PuppetDB and PostgreSQL have additionally considerably decreased in all situations.
instances of Puppet 5 reported by Puppet Server have decreased by 7% to 10% in contrast
to Puppet 4. Puppet 5 can now scale to 40 % extra brokers with no deterioration
in runtime efficiency, whereas Puppet 4 agent runtimes have been disastrously lengthy
when scaled to the identical variety of brokers.
