Instead of setting up all the components manually, Vagrant provides us the feature of using one configuration file (called Vagrantfile), where all the required software components and their configuration information are specified. Vagrant is the modern solution to all these problems.

But due to this manual installation and setup of the components, there might be a slight difference which provides us a lot of pain, because, in such a scenario, the application might run in a development environment, but face issues in the production one.

The development, testing, and production environment should be identical.

The manual configuration might be erroneous, which needs to debug and fix every time.

In every machine, the setup needs to be done separately, which takes a lot of time.

During the setup process, a lot of issues are faced. Prior to Vagrant, all these components need to be set up manually.

as Databases, other components like webserver, load-balancer, API Gateway, Message Queue, etc. as a language, MySQL, Oracle, MongoDB, etc. For example, a modern web application might have components like Java, JavaScript, Python, etc. ISRO CS Syllabus for Scientist/Engineer ExamĪn application consists of several components which need to be configured properly to run the application.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.DevOps Engineering - Planning to Production.Python Backend Development with Django(Live).Android App Development with Kotlin(Live).Full Stack Development with React & Node JS(Live).Java Programming - Beginner to Advanced.Data Structure & Algorithm-Self Paced(C++/JAVA).
