Chef created by Adam Jacob as an tool for his counseling organization. Whose plan of action was to build end-to-end. Moreover named as programmable infrastructure. Explain Chef and its components, Chef uses a pure Ruby, space specific language (DSL) for composing system configurations. Read more at Devops online training

Chef lets you manage them all by transforming infrastructure into code. Infrastructure described as code is adaptable, versionable, intelligible, and testable. Regardless of whether your infrastructure is in cloud, on-premises or in a hybrid environment. You easily and rapidly adjust to your business changing needs with Chef.

Work Station:

One or more workstations arranged to enable clients to writer, test, and look after cookbooks. Cookbooks transferred to Chef server from workstation. A few cookbooks custom to association and others depend on community cookbooks available from Chef Supermarket.

Ruby, programming language that author syntax for cookbooks. Most recipes are simple patterns (obstructs that characterize properties and qualities that guide to particular design things like packages, documents, services, layouts, and users). The full energy of Ruby is accessible for when you need a programming language.

Often, a workstation designed to utilize Chef Development Kit as development toolbox. Chef Development, a bundle from Chef that gives a recommended set of tooling. Including Chef itself, chef command line tool, Test Kitchen, ChefSpec, Berkshelf, and more.

Chef Server:

To enumerate Chef server acts as a center point of data. Cookbooks and policy settings transferred to Chef server by clients from workstations. (Policy settings may likewise be kept up from the Chef server itself, through the Chef management support web UI.)

The chef- client accesses Chef server from hub on which it's installed to get configuration data. Performs searches of recorded chef- client run data. After that pulls down the necessary configuration data and chef client run done. To illustrate chef client’s transfers refreshed run data to Chef server.

Equally Chef management console is the UI for the Chef server. For example It utilizes to manage data bags, attributes, run-records, roles, conditions, and cookbooks. Furthermore to design part based access for clients and groups. Get in touch with OnlineITGuru for mastering the Devops

Chef management console is UI for Chef server. It utilize to manage data bags, attributes, run-records, roles, conditions, and cookbooks. Furthermore to design part based access for clients and groups.

Chef Advantages:chef keep up various platforms like AIX, RHEL/CentOS, FreeBSD, OS X, Solaris, Microsoft Windows and Ubuntu. Extra client platforms incorporate Arch Linux, Debian and Fedora.

Moreover Chef coordinated with cloud-based stages, for example, Internap, Amazon EC2, Google Cloud Platform, OpenStack, SoftLayer, Microsoft Azure and Rackspace to automatically provision  and configure new machines.

In the mean  time, Chef has a dynamic, keen and quickly developing community support.

Due to Chef's majority and adaptability. It used by giants like Mozilla, Expedia, Facebook, HP Public Cloud, Prezi, Xero, Ancestry.com, Rackspace, Get Satisfaction, IGN, Marshall University, Socrata, University of Minnesota, Wharton School of the University of Pennsylvania, Bonobos, Splunk, Citi, DueDil, Disney, and Cheezburger.

Disadvantages:

Keeping up exact, repeatable forms was troublesome.

There were many build failures and tests were frequently running in the wrong situations.

Organization and provisioning times could extend from a few days to several weeks.

Therefore At any rate Operations team didn't approach cloud or improvement conditions.

Most Important Each team uses its own tool set, and there was no responsibility to finance or security. Nobody knew how much an application really cost. Simultaneously Security had no real way to review product stacks.
