Chef can manage a variety of node types, including servers, cloud virtual machines, network devices and containers. The tool is intended to enable developers and IT operations professionals to work together to deploy applications on IT infrastructure. Chef is a Configuration management DevOps tool that manages the infrastructure by writing code rather than using a manual process so that it can be automated, tested and deployed very easily. Chef has Client-server architecture and it supports multiple platforms like Windows, Ubuntu, Centos, and Solaris etc. It can also be integrated with cloud platform like AWS, Google Cloud Platform, and Open Stack etc.

• Chef is used by worlds leading IT industries like Facebook, AWS, HP Public cloud etc.
• The server, which can be hosted locally or remotely, provides the necessary tools to drive the node architectural settings.
• Ohai collects system configuration data to be used in cookbooks and is required to be present on every Chef node.
• In a Chef architecture, you can have a number of nodes that are responsible for collecting all the information regarding current node states.

Much Agile and DevOps work occurs in the cloud, making for easier collaboration and doing away with the need to manage on-premises infrastructure. There are broadly two ways to manage your configurations namely Push and Pull configurations. Let’s say there is a system administrator whose responsibility is to maintain the upstate of all the systems in the network. There may be many systems that need maintenance, which is why it is okay if one of them goes down. One of the traditional deployment workflows is Gannett, which was characterized by various handoffs and manual tests.

Your company might have dedicated individual teams of development and operations working tirelessly round the clock for maximum profitability and revenue generation. Yet, the results do not seem to match the expectation or the projections. Often, the reason for this is the lack of collaboration between teams.

• Test Kitchen provides a development environment on a workstation to create, test, and iterate on cookbooks before distributing its contents to production nodes.
• It would not be a suitable option to sit on every one of the devices and install the software in each of them.
• The Bookshelf is a versioned repository (generally located at /var/opt/opscode/bookshelf; full root access is necessary for access).
• Before getting into Chef deeply let us understand Configuration Management.

With this flavor, the server is hosted within the enterprise infrastructure. Chef comes in various flavors, such as Chef Solo, which has no remote server and cookbooks are located on the local site itself. Ohai is used for determining the system state at beginning of Chef run in Chef-Client. The term “chef on node” refers to an execution in which a chef-client is hosted by and operates within a node as a job and is housed within a VM or container. Progress is the leading provider of application development and digital experience technologies.

What Is Chef – Configuration Management With Chef

In many organizations, those two functions exist in different silos. DevOps brings development and operations together to create a unified infrastructure that maximizes productivity. You should chef certification devops also emphasize on research and the introduction of new tools and frameworks. However, the most crucial aspect of project management refers to the translation of requirements into the workflow.

• Chef is an open source systems management and cloud infrastructure automation platform.
• Similarly, a Chef workstations can download cookbooks found in the Supermarket.
• It also provides an interface to manage nodes, cookbooks, roles, environments, and databags.

All nodes must be bootstrapped over SSH as either the root user or a user with elevated privileges. Cookbooks created on a Chef workstation can be used privately by one organization or uploaded to the Chef Supermarket for others to use. Similarly, a Chef workstations can download cookbooks found in the Supermarket. It was easier to handle peaky traffic because of cloud’s compute-on-demand model, and handoffs were minimized.
