DEVOPS Vagrant Online Training

DEVOPS VAGRANT ONLINE TRAINING @ VIVANTA IT LABS

Vagrant Training is an open source software used to create and manage virtual development environments. It can be considered a wrapper around virtualization software such as VirtualBox and configuration management software such as Chef, Ansible, and Puppet.
Vagrant allows you to use virtualization and cloud technologies to power faster, efficient, and sharable development environments. It duplicates the development environment to allow users to easily share and combine data on different machines and also takes care of security concerns.
