Difference Between VDI and Cloud Computing


Interested for a hassle-free business environment with less managing and security chores? Present innovations in technology bring forth your desire to achieve in your business through the Cloud Computing and Virtualization methods. These terms are a little unclear to many users and newbie of the techno world. Also it’s significant to know and understand the uniqueness and differences of these technologies for a business firm so as to adopt and utilize their services.

Virtualization, a form of cloud computing, is narrowing down your business space and management through virtual machines.  It can be performed with Virtual Desktop Infrastructure (VDI) technique using a centralized data center from which data can be accessed through single server by many virtual desktops. Through VDI, one can run multiple operating systems and applications on numerous virtual desktops eliminating ‘one server-one application’ model. VDI consists of a physical server/PC, a hypervisor to manage the virtual machines, a virtual remote desktop agent to manage and control the desktops using management console and software protocol, and endpoint devices.  VDI helps to reduce the purchase of numerous hardware and other equipments. They enhance power efficiency and produces less e-waste.

Cloud Computing is another techno buzz that offers many benefits to businesses. In simple words, it refers to the process of saving and acquiring the access of data and other programs over the internet instead of using the hard drive. ‘Cloud’ is the metaphor for the internet. Today resources are limited but demands of the users grow exceedingly. This can be leveraged and helped by cloud computing. Cloud based services provide data and resources of high scalability to drive your businesses upfront. You can scale up or down your work and storage depending on the situation. They provide agility of processes due to shared infrastructure and assist to increase your revenue in market by reducing the infrastructure costs.

VDI denotes the centralization of desktop computing whereas cloud computing denotes consolidation of servers into one single resource pool or cloud. Cloud computing constructs and controls a server-side resource pool (cloud) whereas VDI acquires and controls a client-side resource pool (virtual desktop). With VDI, you can prevent breaching of data and data loss in a firm due to hardware failure or data theft because all the data and applications are consolidated and stored in a single server within the centralized data center. Though cloud computing is secure, personalized information can sometimes be breached through hacking (cyber attack) of the internet because the applications and data are accessed over the internet. The virtual resources connected in cloud are cheaper than the physical resources connected to a personal PC or network. You can use the apps that suit your business from the cloud service provider and pay for what you use only. But VDI requires the purchase of all the four components from vendors to suit your business.

With cloud computing, you can drive your business using mobility solutions. With the introduction of smart phones, you can choose an application server that supports big mobile platforms like iOS, Android, Blackberry, etc. VDI assists in optimizing the resources to meet the growing demands of the users. Virtual desktops are best in optimization of every resource within their infrastructure enabling your employees to stay connected for anytime service. With cloud based web portals, your employees are flexible enough to access data from any location to enhance your business performance. Both of them increases flexibility, availability and utility of resources; minimize location dependency, management and administrative tasks and reduce IT costs.

Finally VDI can fix up the large enterprises who toil through the security and management routine whereas Cloud Computing can be utilized by small to mid-sized firms for enhanced performance. It is wise for a firm to assert its needs and then choose on what technology best fits them.
