Docker has been launched in the year 2013 and emerged as a forerunner in containerization. Docker has been the
number one container platform since its launch and became one of the important DevOps tools with its continuous
improvisation. It is a tool to create, deploy and run applications by using containers.
We use Docker in production for most services. It automates application deployment and provides integrated security.
Docker eases configuration management, control, and scaling issues by allowing the container to move from one place
to another place. Docker container allows the developer to package an application with all of the required components
and subcomponents, such as libraries and other dependencies, and ship it all out in the form of a single package. It
automates application deployment and provides integrated security.
The most important advantage of Docker is that it distributes apps into containers to make them more reliable and
transferrable. Besides, Docker simplifies the process of cloud migration. All major cloud service providers such as AWS
and Google cloud extended their support for Docker. So if you have any plans for cloud migration, then Docker can help
you in the process
The following are the Features of Docker:
• Docker Container can be used with any language. • Scale up to 1000’s nodes
• Ship the container wherever you want, either in QA or even the cloud • Update with zero downtime.

has its own domain-specific language. This tool supports the concept of infrastructure as code and dynamic scale up and
down of machines on a need basis. To deliver a secure software puppet automates the entire infrastructure management,
this is the reason nearly 42% of businesses use the Puppet tool.
Puppet runs on various systems, including the Unix system, IBM mainframe, macOS servers, Cisco switches, and Microsoft
windows.
Puppet has two layers: 1. A configuration language which describes the appearance of hosts and services.
2. An abstraction layer which allows the administrator to implement the configuration on a variety of platforms which
includes Windows, Linux, Mac OS, etc.
