Linux Graphical Desktop on Rackspace Cloud : Preface

Linux Graphical Desktop on Rackspace Cloud needs some priming as most has very limited idea on VNC Remote Desktop and the tight integration with OpenCloud. Linux Graphical Desktop is a phrase used by common peoples, the right technical terminology is using a LXDE VNC desktop environment. In other word, you can actually use a fully functional Remote Computer via Internet Connection.

Linux Graphical Desktop on Virtual Private Server

We will discuss Virtual Network Computing and the real hands on guide Linux Graphical Desktop on Rackspace Cloud in two separate articles and guide respectively, this article is mainly intended for the enthusiasts, small business owners, academicians, research institutes – all needs a universally accessible powerful computer that absolutely looks like a usual desktop, takes normal keyboard and mouse commands or touch screen support on a pay as you go model for cost reduction.

Linux Graphical Desktop on Rackspace Cloud : The Must Be Known Points

We are not actually using a Desktop Virtualization, the real server of Rackspace is using OpenStack for the Cloud Configuration and the IP you are getting is actually is of a node. Virtualization on Virtualization is not impossible, but technically difficult and can be unstable.

A : Desktop on Physical Computer

B : VNC Client Software

C : Remote Server's Linux Graphical Desktop

There are difference between the Server Operating System we use and Operating System we install on our working physical personal computer. But, the IP is a public IP, therefore the security should be made be very tight, otherwise such a setup can be hacked. It is better to think of a minimal default homepage when a GET request is done for the IP / domain name or in easy words, if someone opens the domain name or IP on browser. You must be careful about every security loopholes of a Linux Graphical Desktop.
Usually a client software is used to access the Linux Graphical Desktop from Windows, Mac or a Linux PC or even from some Tablets. The advantages of using a Linux Graphical Desktop on Rackspace is, you can get all the advantages of a server but the function of a physical computer. For Linux we generally use Debian or Ubuntu. You can understand, an user can get a 48 GB computer with this Linux Graphical Desktop Setup. Linux Graphical Desktop can be deployed in two ways – as a part of Private or Hybrid Cloud computing or a Public Cloud Computing. We will however discuss the methods for Linux Graphical Desktop setup on Public Cloud as it is hourly charged, you can scale down the RAM to minimum to reduce cost, when not needed. The only limiting factor for such a high end Linux Graphical Desktop on remote server are the geographical distance and Speed of Internet Connection. There are ways to make them better.
