TOP 9 DEVOPS TOOLS

Introduction to Git
Git was created 10 years ago following the Linux
communitys need for SCM (Source Control
Management) software that could support
distributed systems. Git is probably the most
common source management tool available
today. After running Git internally for a short
period of time, we realized that we were better
suited with GitHub. In addition to its great
forking and pull request features, GitHub also
has plugins that can connect with Jenkins to
facilitate integration and deployment. I assume
that mentioning Git to modern IT teams is not
breaking news, but I decided to add to it to the
list due to its great value to us.

Introduction to Jenkins
Jenkins is an open source automation tool written
in Java with plugins built for Continuous
Integration purpose. Jenkins is used to build and
test your software projects continuously making
it easier for developers to integrate changes to
the project, and making it easier for users to
obtain a fresh build. It also allows you to
continuously deliver your software by integrating
with a large number of testing and deployment
technologies.

Introduction to Docker
Docker is a tool designed to make it easier to
create, deploy, and run applications by using
containers. Containers allow a developer to
package up an application with all of the parts
it needs, such as libraries and other
dependencies, and ship it all out as one package.
By doing so, thanks to the container, the
developer can rest assured that the application
will run on any other Linux machine regardless of
any customized settings that machine might have
that could differ from the machine used for
writing and testing the code.

Introduction to Puppet

• Puppet is a Configuration Management tool that is
  used for deploying, configuring and managing
  servers. It performs the following functions
• Defining distinct configurations for each and
  every host, and continuously checking and
  confirming whether the required configuration is
  in place and is not altered (if altered Puppet
  will revert back to the required configuration)
  on the host.
• Dynamic scaling-up and scaling-down of machines.
• Providing control over all your configured
  machines, so a centralized (master-server or
  repo-based) change gets propagated to all,
  automatically.
