Virtualization is a widely used technology nowadays. A whole set of hosting plans is based on it – the so-called Virtual Private Servers (VPS). They allow steady transition from regular shared to the most powerful dedicated solutions. While big projects may require the power of an independent dedicated server, some personal and small-to-medium businesses may not need such resources at high costs at first. At the same time the needs of  such customers may not be satisfied with what regular shared hosting has to offer due its nature . Unlike shared hosting, V PS allows full isolation from other users on the host server. It provides full control over the account (i.e. root access), remote reboots and system restore.

Nowadays various approaches and implementations of virtualization exist. In this article we will compare two most widely used virtualization engines: OpenVZ and Xen. The main goal of the article is to provide basic concept, and outline the differences and similarities of the two engines.

As recently announced by well a known IT giant Microsoft, its Windows Azure Cloud Platform will be launched into production state on January 1 2010. Currently the platform is in its technical preview state, which in a way means that it is not widely available to anyone who wants to “taste” it.

So what is this Cloud Platform? To answer this question we need to answer a question of what a cloud computing is first. As explained by Wikipedia: “Cloud computing is Internet- (“cloud-“) based development and use of computer technology”. Simply speaking, this is an internet based environment aimed at providing software in a form of a ready to use service, with no need to worry about technical specification of the hardware required, installation and configuration procedures and maintenance. All this is being carried out on the side of the Host, on a so-called “Cloud Platform”.

Most hosts today offer server-side security, which means that they protect the servers including the OS and services that run on it. However this doesn’t mean that they guarantee protection of either content or software on your hosting account. There are two main reasons for this:

  • You possesses full login information to your account. This means that if a password is stolen from you the host stops being capable of protecting anything on your hosting account.
  • You are free to install software such as CMS, Ecommerce systems, Blogs, Forums etc. This in turn means that if you put an application that has vulnerabilities your entire site will be in danger. Of course hosts could track all installations on the server, but for a shared server this would simply mean existence of a whole army of administrators monitoring the server 24x7x365 and no such thing as cheap web-hosting would be possible.

As you see the responsibility for keeping your site up-to-date with latest security measures lies mostly on you. But why so much mess about this security thing? Because there are lots of hackers constantly looking for ways to take advantage of someone else’s information. There is no miracle cure for protecting from everything, but there are definitely a few things you can do to ensure better website security. In this article we will tell you about basic web site security measures.

There is a huge number of articles available these days about Google Wave. Some of them describe various features that are yet to be and already are implemented in this astonishing new technology. What I would like to share in this post is our impressions from using Google Wave. Our Sitevalley team got sweet opportunity to get an invitation to use Wave Preview while it is still not freely available to everyone and for this we would like to thank Google a lot! From very start it was a big load of fun to play with waves and actually most features are still not clear enough for us. Here you will find a few feature reviews, some basics about the conception of Google Wave and several personal impressions we got when using it. I also attached a nice extension list and cool video for those who is starting to use Google Wave or is at least interested in doing so some time soon.

Welcome back to Sitevalley blog. In the previous post we have covered the basics of creating the content for your site when using ‘Joomla’ as Content Management Systems. Joomla can be easily installed using the ‘Softaculous’ in your cPanel control panel. The ‘Joomla’ installation is available on ‘Pro Hosting’ Plan.

This is the second part of the tutorial dedicated to the creation of the simplest website. Here we will cover the creation of menus and layout of your website.

So far we’ve been pursuing the following goals:

  • Main topic of the site should be information about computers;
  • There should be 4 sections dedicated to history of computing, hardware, programming languages and computer networking.
  • There should also be a section for the owner of the site that will be dedicated to his personal news and the like.
  • The front page should be dedicated to special stuff.
  • The sections for links, search page and news feeds dedicated to computers should be included. Also news feed should be available on the front page.

At this point you should have performed all actions described in the first part of the tutorial. Therefore you now have all the content related data in your Joomla.
