Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. “Ubuntu” is an ancient African word, meaning “humanity to others”. The Ubuntu distribution brings the spirit of Ubuntu to the software world.

From its outset Ubuntu project has been committed to a regular release cycle and has managed to deliver on that commitment without fail. It is the regularity and reliability of these releases that makes Ubuntu a great option for users and businesses who can plan upgrades and new installs with a reliability that is very unusual in the operating system market. This diagram gives our long term commitment to releases and demonstrates the key difference between a Long Term Support release and our standard releases.
LTS Desktop and Server
Long Term Support releases for desktop and server. There are deployment platforms with wide hardware and software support and ideal or individuals and businesses making a longer term investment in Ubuntu
Standard release
These are the 6 monthly release that contain the best of the new from the Open Source and commercial worlds and suited to users happy to upgrade regularly.
Point Release
These are 6 monthly updates to the long term support cycle. These are primarily bug fixes and patches with occasional feature enhancements that maintain the integrity of the release over a long cycle. The point releases continue up to the next LTS release which then offers an obvious upgrade path for users
LTS Server
This is the extended support period for server.

The short answer is “not really.” You’ll save lots & lots of money by leasing/renting space on your Internet Service Provider’s server or simply utilizing companies such as; Fatcow, SliceHost or MediaTemple. In-house Web servers cost money for hardware, software, system administrators, firewalls, leasing T1 lines, and the list goes on and on. We’re easily talking about an easy $15,000 or more. Compare that to paying a $0/down no set-up fee and as low as $20.00 (standard package) per month to an ISP.
Don’t be talked into it by a computer systems person who wants a new toy. Make sure you need it. You MAY need an in-house Web server if:
- You are getting tens of thousands of hits a day
- You need access to sophisticated programs your ISP won’t install
- You need to provide direct Web access to data from your mainframe
- Lastly, you are like myself who are paranoid and love FULL control
Even then, investigate keeping your hardware physically located at your ISP’s physical location (called “co-location”) to save money, and share the services of a systems administrator and a fast T1 line with other such businesses.
In closing, last night I was asked, ‘why do you host your own web server?’ The reason was simple to me, like most other system administrators, I am paranoid and love FULL control over my company’s resources. I can install and uninstall any possible customization to please me and only me. I also save cost on running Ubuntu Server.
Benefits of running Ubuntu Server is that it is a FREE Operating System, (OS) and includes the following:
Ubuntu users enjoy the unprecedented performance and security that Linux provides.
Because we care about your business we have ensured that the Ubuntu Server Edition:
- Easily integrates with your existing networks.
- Provides a low total cost of ownership.
- Offers multiple life cycle scenarios for you to choose from.
- Is provided with FREE life maintenance.
- Is backed by Canonical’s world-class support.

Furthermore, I can access it at the ‘Root-level’ and perform any action directly ‘on-the-go’ with my Motorola DROID via ConnectBot (A secure shell (SSH) client for the Android platform.)
