- Chef: Chef and Puppet each require brokers to be put in on the managed nodes, which provides an additional step and potential overhead.
- Puppet: Puppet additionally requires agent set up on managed nodes.
Ease of Use

- Chef: Chef gives the next degree of flexibility however could have a steeper studying curve, particularly for customers who usually are not conversant in Ruby or DSLs.
- Puppet: Puppet has a status for being highly effective but additionally having a steeper studying curve as a result of its language and structure.
Group and Ecosystem
