Virtual Machine Hosting

These days the term virtual server has grow to be widespread in the online hosting world. This is definitely not a completely new technology, as the idea has been around since at least the 1980’s, produced by the big computing companies at the time on the Unix system (IBM, DEC, etc.).

Virtual server software (also known as a VDS software), is actually a technology that splits real computing components into several virtual hardware containers which each run their own OS, separate from each other. These virtual private servers can be used for many purposes including:

  • Optimising hardware resource utilisation
  • Running groups of lower intensity programs
  • Providing hardware independent hosting platforms
  • Roaming computer’s desktop replacement

There are numerous virtual server technologies currently available, including:

  • XEN
  • VMware
  • KVM
  • OpenVZ

Each of them have their particular pros and cons, however essentially perform a similar function, which is to create a virtual hardware environment as a way to run an independent OS.

Lots of hosting providers offer you virtual hosting solutions as a way to eliminate the need for clients to deploy any server hardware at all. Instead a client simply rents a virtual machine within the hosting company’s facilities and so removes the need to buy any hardware whatsoever. In these hard economic times we are seeing more and more people turning to VPS as a means to deliver their online services. The need to not deploy physical servers for many people has been a huge benefit in terms of saving time and money.

In addition, the use of a virtualised server often leads to increased uptime for the client, as they are less affected by hardware failures. Most VPS virtual server hosting companies will be able to move the VPS to another physical server in the event of a hardware failure occurring on the server physical server currently hosting your VPS.

10 Minute Guide To Domain Name Registration

Domain names are essential in order for the world wide web to operate correctly. Without a domain name your website cannot be found easily. The domain name system (DNS) is used for converting human friendly names to IP addresses. To identify a specific device within a DNS namespace the hostname or fully qualified domain name (FQDN) is used, for example, http://www.mydomain.com identifies the ‘www’ device in the ‘mydomain’ domain.

The domain registration procedure is used for claiming a domain name to use within the public DNS infrastructure (internet DNS). It’s a very simple procedure, costing very little nowadays. If you want to run a website a domain name is an essential prerequisite. Domain names have multiple levels. All internet registered domains stem from a top level domain. There are now many top-level domains, including:

  • .com
  • .org
  • .co.uk
  • .net

+ many more.

Second level domains reside directly under one a top level domain, for example, mydomain.com, where ‘mydomain’ is this 2nd level domain.

These days there are many domain name extensions readily available for use. Just a few domain extensions such as .com, .org, .net and .edu were offered during the internets infancy. Now many more extensions have become available, for example .me, .tv, etc., due to the surge in internet websites being developed.

There is a specific naming convention used for all domain names without exception. The following restrictions are applied to all domain names:

  • Can include hyphens (-)
  • Maximum 255 characters in total.
  • Must use ASCII letters (A-Z and 0 to 9)

Every level of the domain is separated by a period (.) creating a domain tree.

Most domains may be registered on a yearly cycle, however it is recommended that you register your domains for as many years as you can manage upfront. There are some domain name extensions that employ a minimum two year registration limitation, thus yearly registration is not a possibility. The.co.uk domain name extension is but one such demonstration of this.

The domain name system (DNS) is utilised to convert human friendly names, for instance http://www.example.com, to network addresses called IP addresses, for example 192.168.1.1 which computers use to exchange data. There’s another service for changing IP addresses to domain names, called reverse DNS (rDNS). The system is employed to match up IP addresses to domain names, i.e. the opposite of DNS.

Ubuntu Easy Television Has Arrived

Canonical is going to be pitching a TV-of-the-future idea maximising their touch-based Linux distro along with Ubuntu cloud.

The Ubuntu shop utilised the spotlight among the Consumer Electronics Show (CES) on Mon so as to preview Ubuntu Tv set, a program percolating inside Canonical which received a shot of pr late last year from Mark Shuttleworth.

The concept driving Ubuntu TV, Canonical says, is to deliver Television the way it seemed to be intended: no cables, boxes as well as problems.

Canonical director of communications Gerry Car blogged this: “The goal is to uncomplicate television for the average viewer while delivering to him or her all the services and options that they are becoming used to.”

Ubuntu has been tightly associated with PCs and servers – however Canonical recently shifted into cloud solutions by way of the unveiling of its Ubuntu One service.

Canonical’s classic rallying cry had been “Linux for human beings”. The motto with regard to Ubuntu Television will be “TV for human beings”.

The Ubuntu Television concept shadows as well as extends improvements within the fusion of TV, computing and web. What’s more , it creates the actual Ubuntu media cloud – having Ubuntu 1 for the “web hub” of all things.

We’re told Ubuntu Television will give end users the cabability to pause as well as view programmes on several TVs along with other gadgets, such as touch screen phones.

The enabler for this definitely seems to be Ubuntu One, Canonical’s cloud storage along with data-synching service, which presently allows you to stream tunes and gain access to material with various gadgets. You are able to currently stream music in Ubuntu One to iPhone, iPad and Android devices.

More IBM Patents Sold To Google

In excess of 200 patents were purchased from IBM by Google lately as a way to protect Google services and products from possible future legal cases.

The patents deal with several aspects and technologies, for example:

  • databases
  • wireless telephone systems
  • near-field communications (NFC)
  • cellphones
  • server infrastructure

These patents come in addition to the existing 2,053 bought via IBM by Google within the last year or so. IBM aren’t the sole benefactors of Google’s rising patents acquisitions, as Motorola Mobility also have sold around 17,000 patents and 7000 patents pending, adding up to $12.5 billion US (£7.7 billion). The acquisitions are currently being evaluated by competition regulators. Google has also tried to purchase a further 6000 telecommunications related patents from Nortel, but was unsuccessful in their bid.

Among one of the newest patents is one specifically addressing “identifying common interests between users of the communication network”, that is thought may possibly play a imminent role in Google+. Google’s increasing patents acquisitions have come about to try to safeguard itself against its competitors, which in turn Google accuses of buying up what it has termed “bogus patents” so as to slow up the progression of Google’s mobile operating-system, Android.

Google currently have a number of legal disputes open from the likes of Oracle, Microsoft and Apple relating to some of the technologies utilised inside Android. The present Oracle argument centres around possible Android infringements in relation to Java.p>

Right now there is currently huge competition around with regards various operating systems, specifically mobile variations. In an additional technology patents related lawsuit earlier recently AT&T have been required to pay TiVo US$215 million, plus an extra undisclosed regular monthly licensing payment. It is expected that we now will see more of these patents, software acquisitions and law suits from the major players within the technology marketplace during the coming months. No terms had been presented from both Google or IBM in relation to these most recent patents exchanges.

UK VPS

You can make do with shared hosting services when your web site is just taking off. However, as your site evolves and thus manages to attract more and more people, you probably should consider moving it over to a VPS hosting service local to your target market. For example, if your market is people in the UK, a UK VPS (Virtual Private Server) hosting service would be the best choice.

In comparison with shared hosting, VPS web hosting provides for full control over your hosting setup. This allows the web master to choose exactly which components they require in order to offer up services to their users.

Resource Segregation

With VPS hosting, a single server can be virtually segregated making use of software, so that it becomes individual VPS servers. Each virtual server is separate to any other VPS on the system. In other words, the performance of the website on one virtual server will not interrupt web sites on other virtual servers. When you are using a virtual private server, the hosting company gives you dedicated resources such as:

  • memory
  • processor
  • bandwidth
  • disk space

Each VPS package usually comes with different amounts of each of the above component. Using a VPS allows you to not only provide hosting services, but any other service you can think of due to its highly configurable nature. This is often compared to having a dedicated server, which in many ways a VPS is as good as, if not better.

Dedicated Servers

There are some cases where a dedicated server would be better suited, such as when you have very high resources requirements (e.g. huge amounts of RAM and disk space). In many cases, it is more economical to use dedicated servers hosting instead.
