VVaaggrraanntt Mitchel Hashimoto & John Bender http://vagrantup.com Based on Virtualbox, Ruby Runs on MacOS, Linux, Windows Supports multiple provisioners (puppet/chef/shell/powershell/Salt/Ansible/Docker)* Vagrant lowers development environment setup time, maximizes dev/prod parity,and makes the "works on my machine" excuse a relic of the past.Developers no longer need to worry about setting up complicated infrastructurecomponents. Projects with conflicting dependencies can each get their own sandbox-- keeping a developer's workstation free of the hacks needed for multiple versionsof software to coexist.*http://vagrantup.com 15. WWhhyy wwoouulldd uussee iitt?? Reduces setup time (3 steps & youre ready) Simplicity (you dont have to mess with vbox/vmware api) Self-Service (You dont have to ask for resources) Consistency (Your teammate gets the same exact environment) Repeatability (You can build/destroy/rebuild/shutdown as you please) Contained (You dont have to pollute your laptop and break things, get thedevelopment environment isolated but at the same time connected ) 16. CCaappaabbiilliittiieess Filesharing (A folder from your machine into the virtual machine) Port forwarding (A port from the vm pointing to a local port) Non-Intrusive (You can use your editor/ide from your machine writing into theshared folder) Multi VM Stack Not only one vm per config file You can build many environments as you want only limited by your workstation/laptopresources 17.

DDeevvOOppss && VVaaggrraanntt ccoommmmuunniittyy Chef & Puppet Friendly (Puppet standalone/server, Chef solo/server) We can create/reuse puppet modules or chef recipes Integrate to the cloud environment with minor tweaks Recipes across internet (Just google it: vagrant+project) http://vagrantbox.es You dont have to start from scratch Package (You can create a new basebox based on another according to your needs) Veewee (A tool to automate the creation of a basebox for your particular needs) Dont reinvent the wheelIT Engineering 23. PPrrooffiitt!! Decrease the time it takes for a developer to get up andrunning on a new project Isolate development environments from each other Increase your chance of successful deployment by mirroringthe production environment Reuse your Puppet or Chef recipes in production anddevelopment environments Keep your development machine small and fast 24.
