What Is Chef And Puppet In DevOps

Today, Puppet is considering as the most sophisticated tool for configuration management, but the thing is to deliberate why the puppet is so popular and what makes it unique with other configuration management tools. Whereas Chef is known for a device which is used to control configuration, it is in great competition with Puppet. Before DevOps became a hot topic in the industry, development and operations were completely separate and new servers were manually configured without the cloud. DevOps represents project management best practices for developing and implementing the applications of web or mobile in a communal, isolated, or hybrid cloud hosting environment.

However, DevOp basic requirement is to synchronize code changes for external team members through the publication of program standards. Since Chef and Puppet, both are considering as the DevOps core tools, these tools allow program teams to work together to configure complex web support for specially coded applications that introduce customers to new software features with respect to information technology in many industries. However, many organizations adopted this advanced technology and trained their developers for Puppet DevOps certification and Chef DevOps training by means of stay competitive in the market.

What Is Puppet?

Currently, Puppet is known as a configuration management tool which is supposed to use in order to deploy, install, and manage a server by following the defined standards, it does the following:

  • Make separate settings for each device and constantly check and confirm that the required settings exist and have not been changed, and if changed, the Puppet will return to the required settings on the host.

  • Dynamic scoring of the machines, either scale-up or scale-down.

  • Facilitating the control over all configured devices, so that a central master server based on repo alteration automatically transmitted to all.

  • Puppet uses a master-slave architecture where the master and slave communicate with SSL via a secure encrypted channel.

Puppet- Key Metrics

Here, deliberating the key metrics of Puppet, some facts are about the highlight:

  • Large Foundations: More than 40,000 international companies, together with Google, Red-Hat, Siemens and others, use Puppets, as well as several universities like Stanford and Harvard-Law School. On average, 20 new enterprises use Puppets for the first time.

  • Large Base of Developers: Puppets are so used to it that many developers are cultured; however, the Puppet has many participants in the main source-code.

  • Continuous Business Growth: The Puppet has been commercial since the end of 2004 and is still being refined and developed. Used in a very large infrastructure, over 6000 machines, performance and agility lessons in these projects have contributed to the development of puppets.

  • Documentation: Puppet has a large user-driven wiki with hundreds of full-page references and language and resource types. Additionally, it is dynamically conversed on several mailing lists and has a very common IRC channel, so no matter what’s the problem is through Puppet, the solution is easy to find.

  • Support Platform: The server of the Puppet can be used on any system that supports rubies, such as Central OS, MS-Windows Server, Oracle-Enterprise Linux, etc. Moreover, it also runs on outdated versions of OS and Ruby.

Though it is now clear that Puppets are in high demand in the world, and people are more towards the advanced Puppet DevOps certifications in order to achieve their mutual goals.

What Is Chef?

In the world of technology, Chef is known as an automation tool, which defines Infrastructure as Code (IAS). Simply, a single-layer infrastructure (IAC) involves managing infrastructure by manually writing code rather than using processes infrastructure automation. Though, this can also be called programmable infrastructure. The Chef uses DSL the pure language of Ruby in order to write the system settings. The following are the types of automation that Chef does, regardless of the size of the infrastructure:

  • The configuration of infrastructure

  • The deployment of application

  • Across the whole network, the configuration is managed.

With respect to the Chef, the nodes have been updated dynamically with standard servers. This setting is further known as Pull-Configuration. This means that the developers do not need to execute any commands on the Chef server to convert the settings to the nodes. The node is automatically updated with respect to the setting of the server. Due to these advance updates, many businesses likewise adopted this technology and target their engineers to involve in Chef DevOps training to comprehend the needs as per the market values.

Chef- Key Metrics

Here are the key factors of the Chef which highlighted the incorporation of it:

  • Chef supports multiple platforms like A-IX, Free-BSD, OS-X, MS-Windows and Ubuntu, along with other platforms which include Arch-Linux, Debian and Fedora.

  • Chef can be supposed to integrate into the cloud computing platforms such as Inter-nap, Amazon-EC2, Google-Cloud Platform, Open-Stack, Soft-Layer, MS-Azure and Rack-space to automatically secure and configure the fresh machines.

  • Chef receives an active, smooth and rapidly growing support of the community.

Configuration Management

Configuration management is shaped to resolve the issues which incorporated with the Chef and Puppet installations. By using the tools of the configuration management such as Chef, and Puppet, developers can automate the respective task. All that has to do is to specify the settings for the central server and configuring all the nodes. In short, that need to be done is to recognize the server settings once and copy them to hundreds of the nodes gradually. However, configuration management helps to complete the following tasks in a very structured and simple way:

  • Decide which components will need to change as the changes required.

  • Repeat the process as the requirements have changed since the last procedure.

  • Revert to the previous version of the component, if upgraded to a new but corrupted version.

  • Replace the wrong component because the developer could not determine exactly which component to replace.

However, there are usually two ways by means of managing the settings:

Pull-Configuration: With respect to this type, the nodes regularly require server updates. Thus these nodes are synchronized; they remove the setting of the server. However, the pull-configuration method uses tools such as Chef, Puppet, etc.

Push-Configuration: In this type, the server switches settings to the nodes. Unlike switch settings, multiple commands must be run on the server to the configured nodes. Push-configuration mode is used by devices like Ansible.
