Enterprise Virtual Desktop Infrastructure Architecture on OpenStack Cloud with Lightweight Directory Access Protocol

Virtual Desktop Infrastructure (VDI) is a Virtualized Technology that hosts the user's desktop at Datacenter Server. OpenStack is the most successful opensource enterprise cloud platform. Cloud-based VDI, also known as “Desktop as a Service” or DaaS, increases utilization of Datacenter infrastructure, provides high elasticity, increases service diversity, and improves scalability. It also allows for prioritizing delivering value, give the choices to use a wide range of hypervisor/storage/network. In this paper, an architecture proposed that comprises three major components that are, hypervisor, connection broker, and display protocol for enterprise-level VDI on OpenStack. The hypervisor used to host many virtual machines on a single hardware. Connection broker used for configuring, inventorying, provisioning, and centralized management of desktops and display protocol allows users to view the desktop that hosted at Datacenter. Lightweight Directory Access Protocol (LDAP) used for user authentication and authorization for desktops. In the paper, we explore the architecture design and implementation of the VDI system on OpenStack and verifies the experiment results.
