Chef DevOps
What is Chef?
Chef is an open source innovation
created by Opscode. Adam Jacob, fellow benefactor of Opscode is known as the
founder of Chef. This innovation utilizes Ruby encoding to develop essential
building blocks like recipe and cookbooks.
Purpose of Chef
Chef is utilized in foundation
automation and aides in decreasing manual and tedious errands for frameworks.
Chef has its own convention for various building blocks, which are required to
oversee and automate infrastructure.
Chef’s Features
Following are the most conspicuous
features of Chef
·
Chef utilizes well known
Ruby language to make domain-specific language.
·
Chef doesn't make
presumptions on the present status of a node. It utilizes its systems to get
the present status of machine.
·
Chef is perfect for sending
and dealing with the cloud server, storage, and programming.
Benefits of Chef
·
Quickening programming delivery, when your framework is automated all the product prerequisites
like testing, making new conditions for programming arrangements and so forth
turns out to be quicker.
·
Expanded assistance Resiliency, by
making the framework computerized it screens for bugs and mistakes before they
happen it can likewise recuperate from blunders all the more rapidly.
·
Risk Management, the chef
brings down hazards and improves consistency at all phases of deployment. It
diminishes the contentions during the development and production environment.
·
Cloud Adoption, Chef can
be effectively adjusted to a cloud situation and the servers and framework can
be effectively arranged, installed and managed automatically by Chef.
·
To manage Data Centers and Cloud Environments,
Chef can run on various stages, it also can deal with all your cloud and
on-premise stages including servers.
·
Streamlined IT activity and Workflow, Chef gives a pipeline to consistent deployment beginning from
working to testing and entirely through delivery, observing, and troubleshooting.
Architecture of Chef
Chef deals with a three-level customer
server model wherein the working units, for example, cookbooks are created on
the Chef workstation. From the order line utilities, for example, knife, they
are transferred to the Chef server and every one of the nodes which are
available in the architecture are enlisted with the Chef server.
So as to get the working Chef foundation
set up, we have to set up different things in sequence.

Difference between Chef and Puppet
Puppet is an incredible enterprise-grade
setup the management tool. Both Chef and Puppet help development and operations
groups oversee applications and infrastructure. Anyway, they have significant
differences you ought to comprehend while assessing which one is directly for
you.
·
The architecture of Chef and
Puppet is comparative, yet they vary somewhat on how they handle HA.
·
In Puppet, the master recreates its
information to another server and they work in an active/passive way. For
Chef, HA is taken care of with three servers in an active/passive mode with an
API front end that can scale evenly.
·
Tools contrast by the way
you create and test recipes or manifests. Chef has a workstation including the
Chef SDK that you can introduce in your PC as a staging environment.
·
Puppet doesn't have a
workstation, yet it has an SDK where you can test manifests while creating them.
Additionally, you can apply manifests locally with the puppet apply command.
