When are Virtual Private Servers (VPS) a Logical Alternative to Shared or Dedicated Hosting?

September 3rd, 2010 Steve No comments

A Virtual Private Server (VPS) – is the next logical step up from a shared platform. Its scalability in resources versus cost makes it a viable alternative to dedicated server hosting.  

While Virtual Private Servers – offer the same complement of operating systems and software components expected from a dedicated server, they vary from shared in that each virtual private server is isolated from one another, allowing concurrent execution of multiple operating systems – without allowing the execution of one partition to adversely affect the performance of another partition. Instead of allowing the kernel or operating system of a VPS to interface directly with hardware components, virtualization software intercepts requests, queues them, and manages their interpretation.

A Virtual Private Server platform – is ideally suited for:

Low End

  • Stand Alone Services
    • Private Proxies
    • Small Email Server
    • VPN Endpoint
    • DNS Server
  • Static Websites

 Low to Mid Range

  • Small to Moderately Dynamic Sites
  • Repositories
  • FTP Servers
  • Databases

 Mid Range

  • Dynamic Websites
  • Entry Level Web Servers
  • Busy Email Servers
  • Remote Linux Desktops

 Mid Range to High End

  • Large Dynamic Websites
  • Hosting Multiple Sites
  • Hosting Forums
  • Hosting Complex Applications

 High End (rivals most low end dedicated server packages)

  • Hosting Tons of Client Sites
  • Hosting Large Forums
  • Hosting eCommerce Sites
  • Windows Terminal Services
  • File Servers
  • SharePoint and Extensive Database Applications

Xen™ virtualization explained

August 16th, 2010 Steve No comments

Xen™ – is a virtual machine environment that supports execution of multiple guest operating systems with outstanding levels of performance and resource isolation. Xen is Open Source software, released under the terms of the GNU General Public License.

Servers likeHostirian’s Dedicated Servers are ideally suited to employ virtualization to present the illusion of many smaller virtual machines, each running a separate operating system.

Virtual machines – on one dedicated server are isolated from one another, allowing concurrent execution of multiple operating systems – without allowing the execution of one to adversely affect the performance of another partition.

XEN Hypervisor – is a layer of software running directly on the server’s hardware, replacing the operating system, which allows that server’s hardware to run multiple guest operating systems concurrently. It becomes the interface for all hardware requests such as CPU, I/O, and disk for the guest operating systems.

Server virtualization benefits

  • dynamic fault tolerance against software failures (through rapid bootstrapping or rebooting)
  • hardware fault tolerance (through migration of a virtual machine to different hardware)
  • the ability to securely separate virtual operating systems
  • the ability to support legacy software as well as new OS instances on the same computer

Killing off Result5.Google

August 1st, 2010 Steve No comments

I had to tackle result5.google this past weekend, and what I thought at first was a virus was actually a re-direct to Russia. One of my friends was having problems searching, as his results were constantly being re-directed to advertising pages. He was running a small three computer network in his home with a Linksys wireless router.

Trying to access or download any type of anti-virus program was fruitless and scans with Microsoft Security Essentials and StopZilla turned up other viruses, but didn’t kill off result5.google. Neither did Malwarebytes.

Searches on Bing and Google returned plenty of posts on how to eliminate this problem, but only one helped – and that was to log onto the router, correct the DNS and change the password, then empty his computers’ history, temp pages and cookies. Seems his router’s DNS had been changed to 213.109.67.169 and 213.109.73.170, which a traceroute revealed pointed to Eastern Europe. When he installed his network, he neglected to change the router’s password from the vendor’s default, leaving himself open to exploits.

Typically, routers are marked with their serial numbers and MAC addresses, and from there you can search the vendors online support pages to determine its IP and how to log on to the router to change its password and settings.

I hope this helps anyone out there who is experiencing this problem.

Want LOTS of FREE Traffic from Google?

July 20th, 2010 Steve 8 comments

I read a ton of articles, threads and posts from SEO experts everyday. Why? Because just like everyone else, I want to increase sales online. For years, SEO practitioners preached a mix of link this and content that, or touted banner advertisements or AdSense ads. Since the onset of search engines, techniques to outwit them to rank higher in Search Engine Results Pages (SERPS) have basically evolved beyond simply obtaining backlinks, providing lots of content or optimizing keywords and meta tags.

FREE versus Paid Traffic
Organic traffic is traffic you receive from free click-throughs in search engines (not sponsored) – the higher your site ranks, the more traffic you receive, thus higher revenues on the backside. Paid traffic would be traffic obtained via banner ads or programs like AdSense. Bottom line to increase profits – reduce overhead – increase productivity. So how do you make your website more productive without forking out a ton of money on paid advertising?

Google Algorithms Put to the Test
For years, I’ve been reading about how complex Google algorithms were. We’ve witnessed a number of cycles or shifts in how Google analyzes and ranks sites, but if you tie in Google’s history of acquisitions and free tools, their core emphasis (today) lies within three (3) PRIMARY variables – all driven by human activity. Much like Bing, they’ve transitioned from being a search engine to being a decision engine.

So What is this ‘FREE Traffic” Big Secret?
I can’t tell you the number of times I’ve seen the phrase, “Content is King” or “Content is King Kong.” I’ve said this myself in a past life. The real KING today is Organic Search Traffic!! Think about this for a second. What does paid advertising get you – a position on a page with the expectation that being seen at the top of that page will result in a click through to your site.

Viewing Patterns Take Center Stage
Numerous studies have been conducted by leading SEO firms to determine viewing patterns and projected click through patterns over the years. Going back to the early 2000’s, banner advertising worked very well, drawing over a 30% click through rate. When banner advertising fell out of favor, the trend evolved to link building, but a ton of black hat SEO strategies forced Google to revise their algorithms.

So what do today’s viewing patterns tell us about paid ads?
Very simply that organic traffic is growing and paid is declining. Here’s a question for you – when you do a search query on Google, do you read the sponsored ads at the top of the page or the ads on the side bar? Studies have shown that those viewers who do read them is on the decline. Consider this – sponsored ads were only drawing 5% of the click throughs in their prime, and even less now. So where are the other 95% of the click throughs occurring? The answer is in Google’s organic listings – the FREE ones!! Banner Ads don’t even register and sponsored ads aren’t much better. Currently, paid listings that appear above the organic listings receive only 2 to 3 percent of the available clicks with those on the side receiving a paltry 1 to 2 percent. To verify this, you simply have to use Google’s own internal Traffic Estimator Tool.

Organic Traffic is KING
Not only is organic traffic FREE, but it also receives the majority of all traffic. The first organic listing receives over 40% of the available traffic, while the second, or number two, receives nearly 20%. Let’s say you’re running an AdWords campaign and you’re getting 1000 clicks per day (multiply those clicks by your cost per click – OUCH). Compare that to number one in Google’s organic listing at 40%. Your paid 1000 clicks translate to 8000 FREE organic clicks. And viewing patterns indicate the first ten organic search positions outperform even the number 1 paid ad on the same page. OK, you’re saying that you know it’s important to rank high in SERPS, so how is this a big secret?

What does Google look at today to rank organic listings?
While Google doesn’t divulge their algorithms publicly, they do post recommendations and guidance. We do know they look at content, which is essentially the domain name itself, certain meta tags and so. They still look at links, both inbound and outbound, assigning authority to those links. And this should be no surprise – they look at the human element – activity. This consists of traffic, RSS subscriptions, comments on blogs, updates to your site and so on.

How do today’s algorithms differ from years past?

I think we all remember PageRank. Up until about 2003, Google counted the number of inbound links to a site, applied a ranking score to each (based on quality), and the sites with the most quality inbound links ranked highest.

When Google introduced Adsense, a shift to content ensued. The focus was to create a ton of pages with content – then place Google’s ads on them. When visitors to those websites clicked thru on the ads, Google split the ad revenue with the site owners. What happened?  For a few years, content worked well, but the SERPS began to be overrun with spam. Another shift was incorporated to regain relevancy, going back to a more robust emphasis on links. This was quickly countered with SEO tactics like link wheels, irrelevant comments on do-follow blogs, robotic article rewrites that were posted everywhere linking back to a main website.  

Enter Google Caffeine
Essentially, Caffeine rewards activity and freshness, meaning more relevance is given to sites that routinely update their content. They still factor in link juice and volume of relevant content, but human activity (social media) is the prevailing trend across all industries.

Over the years, Google has invested heavily in technology that measures HUMAN ACTIVITY. Think about all the programs and businesses they’ve invested in, many that never turned one penny in profit. Why? As long as SEO practitioners could automate strategies to exploit Google’s algorithms, their rankings and AdSense revenue was diluted.

Going Forward
Consider this – with the addition of FeedBurner, Chrome, Google Analytics, Google’s Toolbar and on and on, user statistics are being sent to Google on a massive scale. With Caffeine, their algorithms have shifted once again – only now with primary emphasis on traffic. Note – avoid automated programs. Google has garnered a wealth of information about human trends and SEO tactics over the years, and can see through most attempts to exploit their services.

It’s best to create organic websites that are highly relevant to the service or products you offer, then create activity on that site by embracing social media (Facebook, Twitter, etc), incorporating a do-follow blog (moderating comments and disabling spam links), then tweak your site as needed.

If done properly, your website will not (realistically) leap to number one overnight, but will rise in Google’s rankings over the first 30 to 90 days. Back links and quality content are still important, but my recommendation is to emphasize ACTIVITY.

To Your Success

Private versus Public Cloud Services

July 15th, 2010 Steve 3 comments

Private versus Public Cloud Solutions
Let’s face it, there are BILLIONS of dollars invested in existing IT infrastructure. As more and more enterprise vendors step into the cloud arena, will business in general migrate to the public cloud or opt instead to keep much of their investment in legacy code and custom applications in-house via a private cloud?

The future of cloud computing is up in the air (pun intended)
At this point, we don’t really know how cloud technology is going to shake out. Even if cloud technology gets huge, there’s likely to be a split between private and public clouds for the foreseeable decade. I think as the industry matures, you’ll see commodity services migrate to the public cloud and mission-critical stuff linger in a private cloud.

OK, so what is cloud computing?
Essentially, cloud computing is simply another way of delivering computing resources to run websites and web applications. It allows clients to scale their operations, horizontally and vertically, based on the demands of their users, while ensuring that there are adequate resources to support their apps. You can think of it as technology services delivered on-demand.

Traditional web hosting services are offered in packages with set limits on disk space and data transfer, so as traffic fluctuates, data and transfer needs vary resulting in excess, unused capacity during lean times.

Who could benefit from Cloud Services?
Essentially, everyone could benefit from cloud technology. Businesses that experience seasonal spikes, especially eCommerce retailers, where 80+ percent of their business peaks during holiday seasons, are prime candidates for cloud services.Cloud computing offers those businesses enough services to meet their increased traffic demands, then the option to scale back after the holidays, aligning their operating costs with revenue.

Taking the lead from the BIG vendors
Nearly all of the BIG vendors, from Microsoft to HP and IBM to CISCO, are talking cloud, with most listing their top two priorities as virtualization and cloud computing (virtualization is a cloud enabler). Google and Amazon already host public clouds while vendors like EMC are promoting solutions that virtualize existing servers and storage (private cloud).

Types of private versus public cloud solutions
As the following graphic from Microsoft highlights, there are choices to both private and public cloud services. Of course, these are not all inclusive. In the following months, I’ll address different cloud scenarios, demystifying some of the confusion about what cloud services really offer
