DevOps, a design philosophy that mixes software program improvement and data know-how operations, has an unlimited collection of instruments to select from. Chef and Puppet are two of the extra standard DevOps instruments on the market, however the large query that arises is, which alternative is one of the best for you?
We need to assist DevOps designers make a educated determination. To that finish, we current this text, which outlines the variations and similarities of the 2 configuration administration instruments. There are plenty of articles on the market that do these sorts of comparisons, do you have to need to do extra analysis. However no matter how a lot analysis you determine to do, by the point you’re accomplished with this text, you’ll actually have a greater concept which of those two particular instruments is finest suited on your distinctive state of affairs.
So let’s dive proper into Chef vs. Puppet!

To cite the designers, Chef is “…a powerful automation platform that transforms infrastructure into code. Whether you’re operating in the cloud, on-premises, or in a hybrid environment, Chef automates how infrastructure is configured, deployed, and managed across your network, no matter its size.”
A chef is an open-source cloud configuration that interprets system administration duties into reusable definitions, in any other case often called cookbooks and recipes, which is why it’s named Chef. Is smart, no?
Chef runs on a strong mixture of platforms, together with Home windows; enterprise Linux distributions; AIX; FreeBSD; Solaris; Cisco IO; and Nexus. As well as, Chef additionally helps cloud platforms together with Amazon Net Companies (AWS),
Google Cloud Platform, OpenStack, IBM Bluemix, HPE Cloud, Microsoft Azure, VMware vRealize Automation, and Rackspace.
In accordance with the designer’s web site, Puppet is an open-source programs administration instrument created for centralizing and automating configuration administration. It contains its personal declarative language to explain system configuration.
Puppet runs on the next platforms: Purple Hat Enterprise Linux (and derivatives), SUSE Linux Enterprise Server, Debian, Ubuntu, Fedora, Microsoft Home windows (Server OS), Microsoft Home windows (Shopper OS) 10 Enterprise 7, 8, 10, macOS 10.12 Sierra, 10.13 Excessive Sierra.
Puppet and its conditions have been reportedly run on the next platforms, although Puppet doesn’t present official open-source packages or carry out automated testing:
Different Linux: Gentoo Linux, Mandriva Company Server 4, Arch Linux
Different Unix: Oracle Solaris model 10 and better, AIX model 6.1 and better, FreeBSD 4.7 and later, OpenBSD 4.1 and later, HP-UX.
How Do Puppet and Chef Stack Up In opposition to Every Different?
Now that we have now an concept the place every of those instruments is coming from, how do they evaluate? Are they extra comparable or completely different, and which is best for you?
We’ll get our solutions by breaking down the instruments primarily based on some necessary traits:
- Availability: On this context, availability is outlined as how accessible the instruments are throughout unscheduled service interruptions. If Chef’s major server goes down, a backup server takes up the slack. Puppet incorporates a multi-master structure, so if the energetic grasp is down, there’s one other grasp to fill in for it.
- Phrases and Ideas: For the reason that configuration managers summary the configuration recordsdata, it’s necessary to familiarize your self with the phrases distinctive to every instrument. The chef has you working with cookbooks and recipes, whereas Puppet works with manifests and modules. Recipes and manifests, as a rule, describe single ideas, whereas cookbooks and recipes describe extra common ideas.
- Enterprise Price: Chef Automate has an annual payment of $137 per node, and that worth provides you all the pieces it’s worthwhile to construct and deploy. Puppet costs vary from $112 per node/yr when you select the usual help plan, as much as $199 per node/yr bundling within the premium help plan.
What They Have in Frequent
A lot for the variations. What do these two instruments have in frequent?
- The Setup: Chef capabilities with a master-client structure, with the server working on the grasp machine, whereas the consumer runs as an agent on each consumer machine. Chef additionally contains an extra part referred to as “Workstation,” which handles all the configurations which are examined by storing then pushing them to the central server.
Puppet makes use of a master-agent structure association as properly. The Puppet server runs on the grasp machine, whereas Puppet purchasers run as an agent on every consumer machine. Additionally, there’s an agent-master certificates signing that takes place afterward.
So, in different phrases, each instruments are troublesome to put in.
- Managing the Instruments: When you’re utilizing Chef, then be able to entry your programming expertise as a result of you will have them to handle configurations efficiently. Chef’s consumer pulls configurations from the server, and people configurations are in Ruby DSL.
Puppet isn’t any much less concerned, sadly. It makes use of its personal language referred to as PuppetDSL (Area Particular Language). The method is oriented in the direction of system directors and options non-immediate distant execution.
The underside line, each instruments use the pull configurations. That signifies that the slave nodes routinely pull configurations from the central server with out the necessity for any instructions. That is versus the push configuration, the place all of the configurations current within the central server are pushed to the nodes.
- Scalability: Each Chef and Puppet are very simply scalable. They’ll each deal with giant infrastructure, supplied the consumer gives the IP tackle and hostname of the nodes that must be configured. The instruments will deal with the remainder.
- Configuration Language: Chef makes use of Ruby DSL (Area Particular Language), a developer-oriented language that’s difficult to be taught. Puppet employs the above-mentioned PuppetDSL, one other troublesome to be taught the language.
- Interoperability: Each the Chef server and the Ruby server work solely on a Linux/Unix machine. Chef Consumer and Workstation can run on Home windows, and Puppet Agent is suitable with Home windows.
The Professionals and Cons of Every Instrument
In an effort to paint a easy, simple image, let’s check out a pattern of the professionals and cons of Chef vs. Puppet.
- The entire Consumer Interface
- Highly effective reporting capabilities
- Grants entry to a well-established help neighborhood
- Assist for pre-Ruby variations is within the technique of being scaled again
- Its model-driven strategy equals much less management when in comparison with code-driven approaches
- Superior duties require CLI, and since it’s primarily based on Ruby, you’ll must be acquainted with the latter
- Its code-driven strategy means larger flexibility and management of configurations
- The “Knife” instrument lessens set up complications
- Supplies you with an intensive assortment of configuration and module recipes
- Doesn’t help push performance
- When you don’t already know Ruby and procedural coding, prepare for a steep studying curve
- It’s a fancy instrument
Within the last evaluation, the perfect DevOps instrument is determined by the wants and targets of your group. Chef has been in existence for a very long time compared with most different DevOps instruments and demonstrates a superb functionality for dealing with extraordinarily advanced duties. In case your group has development-focused groups and environments, then Chef is the perfect alternative.
Puppet has additionally been round for fairly some time and has been deployed and well-vetted in a collection of giant, demanding environments. Primarily based on this, Puppet is an efficient alternative for bigger enterprises that favor well-tested and long-standing instruments.
The ultimate alternative comes right down to realizing what’s necessary for what you are promoting.
