VMs in the Big Data Lab
The datacenter in the Big Data Lab provides a cloud computing infrastructure supported by 21 servers with the VMware vSphere platform. VMware vSphere is a virtualization platform for running virtual machines (VMs) in a large scale computing environment. VMs in the Big Data Lab can be managed through the vSphere Client or through OpenNebula. Big Data Lab VMs are subject to the Virtual Machine Policy and the Acceptable Use Guidelines.
The vSphere web or desktop client is used to access and manage VMs in the Big Data Lab via a vCenter Server. For step-by-step directions on using the vSphere Client, please see How to access virtual machines in the Big Data Lab.
OpenNebula is an free and open-source cloud infrastructure management platform that provides a web interface for provisioning and centralized management of virtual machines. OpenNebula's virtual appliance, called vOneCloud, brings OpenNebula to vSphere for a self-service cloud provisioning portal on top of an VMware infrastructure environment.
To access OpenNebula, first connect to the VPN (if you are off-campus) and then login to one.cs.hofstra.edu with your Hofstra portal credentials.
VPN remote access
The Computer Science Virtual Private Network (VPN) allows students and faculty to access resources of the Big Data Lab from off campus over the Internet. To connect to the VPN, you must install an OpenVPN client and obtain a client profile from csconnect.hofstra.edu.
Git is a free and open source version control system (VCS) widely used for source code management (SCM) in software development. Developed by Linus Torvalds and others in 2005 to aid in the development of the Linux kernel, the unique design and efficiency of Git has made it a popular tool among numerous open-source projects. Git is a command-line tool with broad support by many third-party graphical user interface (GUI) frontends.
Students and faculty can store and collaborate on projects at git.cs.hofstra.edu or utilize GitHub for personal projects. GitHub, a Git repository hosting service that is home to millions of open-source projects, offers free private repository hosting to students through the GitHub Education program.
Please see Getting started with Git for an introduction and setup directions.
