Virtual Web Servers - The Perfect Alternative to Shared Hosting

If you're like most webmasters out there, you've probably started off with shared hosting at one point or another. Though shared hosting has some advantages, by nature the hosting is shared with plenty of other websites. In order to cut costs, shared hosting companies over pack many accounts all on one single server. This can cause plenty of problems which shared hosting is all too known for, especially slow download speeds as well as sporadic downtime.

If your website is seeing a good amount of success, many would suggest that you switch to your own dedicated server. If you've seen the prices for a dedicated server, you know that costs can run high.

There is a solution in between shared hosting and dedicated hosting which is called a virtual web server. A dedicated virtual web server will let you operate your own websites as if you actually owned the server virtually. Each virtual web server has direct control over its own resources like RAM, CPU, and others. Each and every virtual web server is completely isolated from other virtual web servers, so you won't be affected in any way by the actions of other webmasters and their domains/servers.

If you treat your website like a business, or even if it is an e-commerce site, then getting a virtual web server is probably the best route for you to take. When it comes to giving your website a home on the Internet, you'll definitely want a presence that's going to be up at all times, with top download speeds.

You also have the option of installing any application on your server that you'd like. No longer are the problems of not being able to run certain web applications on your shared server because your hosting company doesn't support them. If you want something, simply install it on your virtual server. A single virtual web server will give you the flexible solution that you need for web hosting.

Web-Based SMTP Server Monitoring

Web-based monitoring of SMTP email servers is normally conducted using one of two different approaches. The first uses a socket level connection to verify whether or not the target server is operational. The second more comprehensive method involves sending round-robin messages to your email system and its subcomponents. Depending on your needs, hardware, and company size both have validity and a rightful place. To determine what is best for your company, let's examine both in more detail and the advantages and disadvantages of each.

Socket connection is the most prevalent method used by web-based monitoring companies due to its simplicity. A DNS check is normally conducted, then a socket level connection to port 25 of your email server is attempted. If DNS is ok and SMTP port 25 handshaking occurs, the server is viewed as operational. If not, the appropriate notification methods are triggered. The socket connection method advantages are: speed, low bandwidth, and no agent or server changes are required. Because of its simplistic design, socket connection monitoring can be used to monitor SMTP servers your company does not own or manage. The disadvantage to this approach is accuracy. Just because DNS is operational and handshaking occurs, it does not mean the server or subcomponents are actually processing messages.

The second, less used, method involves a round-robin process that actually sends test messages to your email systems and waits for the message to be returned. As with the socket connection method, a DNS check is normally performed first. A test message is then sent by the monitoring company to your email system. The message travels through your gateways, any subcomponents such as antivirus and content/spam filters, through the firewall to the designated internal server. The internal server, based on a pre-established server-based rule, returns the message back to the monitoring company. If the message is received by the monitoring company within the preset time, 15 or 30 minutes for example, the email system and subcomponents are viewed as operational. If not, the appropriate notification methods are triggered.

If you are using Microsoft Outlook & Exchange, a server-based rule would look something like this: Apply this rule after the message arrives from EmailVerify@SiteRecon.com and with "Email Verification for" in the subject forward it to "Webmaster@SiteRecon.com

The advantage of this approach includes the ability to check the complete message process for failures. For example, a gateway checked using the socket connection method could be fully operational, yet a connected spam filtering appliance or antivirus process could be hung halting message processing. Depending on the monitoring company, the ability to include a specific type of attachment to the round-robin process is also available. Including an attachment such as the Eicar.Txt text pattern for example, permits subcomponents such as antivirus to be fully tested. The disadvantages to this approach are: increased processing by your servers as this testing method sends 96 messages per day using a 15 minute monitoring interval; creation of an email account to receive the test message; and establishment of a server based rule.

The diagram outlines the process for both round-robin and socket connect monitoring methods.

Clearly, the round-robin method offers a more comprehensive testing process than the socket connection method. However, depending upon your needs both process have a rightful place in verifying your email systems are up and operational.

If you do not have the ability to establish server based rules, your only choice is to use monitoring based on the socket connection method. If you have the ability to establish rules, the round robin process offers a much more comprehensive testing method.

Socket connection type monitoring is offered by a wide range of companies and prices vary widely. Round-robin processing is offered by SiteRecon and Websitepulse and range from $11 to $29 per month depending on the monitoring frequency.

Is Your Website Secure On A Shared Server? Part 2

SSL certificates The secured socket layer (SSL) technology provides strong encryption of HTTP packets during their transfer through the World Wide Web. However, in order to encrypt; a SSL certificate from a trusted certification authority like Verisign or Twate is necessary.

Shared hosting and SSL certificates SSL can undoubtedly provide a lot of security on the server side. Most of the encryption done is on the 128 bit level, which in its own right is very secure. But, when it comes to securing websites on shared hosts the real problems surface as the SSL technology requires an IP address ( with port number) and most shared websites don?t have one!

To overcome this problem many ISP?s have come-up with shared SSL certificates. But, this quick fix solution actually undermines the importance of SSL certificates as, with a shares SSL certificate the credibility and trustworthiness of a certificate comes under the scanner.

However new methods are being developed at a rapid pace whereby Genuine SSL certificates would be provided to websites operating on shared hosts and with the evolution of IPv6 (The new generation of Internet Protocol) the scarcity of public IP?s would also be addressed to a certain extent).

Other practical methods to ensure security on shared servers

• You should have complete information about the types of scripts and software installed on the server. As applying unproven or substandard codes by others using the server might affect you too.
• Enquire about the security audit procedure employed by your host. That?s because the frequency of review can be the deciding factor between succumbing to a security threat and overcoming it.
• The most important action you can take on your part is to use very strong password for your website. As using easy to crack password would make your website as open as a stadium in front of hackers.

When we talk of the World Wide Web and its secure nature, we have to understand that nothing is fool-proof. Recent times have seen hackers breaking in to some of the most secure websites. That?s why, the trick here lies in keeping up with the times and heeding to the latest of security updates. A web hosting provider who does that can provide a great deal of security to your website even if it?s hosted on a shared server.

Because a good web design attracts user and some time visitor loves the design and bookmark the same site for future visits or for future reference or might be interested in making the same web design for his clients or might be possible he/she will edit the same design. But this is true that your website must have a good design. Not only to attract the internet visitor but also helps in browsing the products & services, so that visitor can reach to the destination with the minimum number of clicks.

Web Designing - While audience creation, advertising and promotions drive traffic to a site, it's the design that either encourages visitors to explore or drives them away in frustration. A good design is, of course, aesthetically pleasing. More importantly, though, it engages visitors, makes it easy for them to navigate the site and compels them to explore the site further, purchase products and return another day. Attractive graphics that support the company's message are important. But large graphics that take a long time to load frustrate users. Many visitors won't wait long enough for the graphic to finish loading. Additionally, visitors are less likely to return to a site that has cumbersome or confusing navigational cues. Selection of a Web Designing Company is always a big game as far as your online business is concern. Web design differs significantly from design for other media.

Is Your Website Secure On A Shared Server? Part 1

Security aspects of a shared web hosting server have always on the forefront. And, with almost 90% of websites being hosted on shared servers, the security considerations are not uncalled for.

Also know as virtual hosting, shared hosting has been the favorite of small and medium size enterprises. Owing to the fact that shared web hosting works out to be cheaper than hosting on dedicated servers. That?s because a website shares a server with other websites in a virtual environment. But, does that make it vulnerable to hacking? That?s the million dollar question. To understand the security aspects of hosting on shared servers, we will have to first understand the different modes of shared hosting.

Types of shared hosting

• Domain based shared hosting:

It works on the Virtual Private Server (VPS) technology and provides each website with a unique URL, even though they are hosted on a single server. The VPS technology achieves by creating effective partitions in the server and gets them to act as individual servers.

• Name based shared hosting:

In name based shared hosting, a websites name appears as a subset of the service providers name. Example of such service providers are geocities, blogspot etc.

• Directory based shared hosting:

With respect to directory based shared hosting, the customers website will be mentioned as a directory in the host domain name. The most important point that comes through with shared hosting is the relative lack of a dedicated IP address. That?s because most of the web security apparatus are applicable on the IP address level. That?s the reason why, dedicated severs are capable of providing a more secure environment; as they guarantee a unique IP address.

The other blockade with shared server security is the relative difficulty encountered in implementing SSL certificates.

Virtual Dedicated Server Hosting

A virtual private server, also known as virtual dedicated server, provides one of the ways of partitioning one server computer into multiple servers. By this, each server has the facade and capabilities of running on its own dedicated machine or computer. In each virtual private server hosting, a full-fledged operating system can independently run and reboot each server.

Virtual private server hosting is not a new technology as it had been in common practice in mainframe computers. However, it has its rebirth with the improvement of virtualization software and technologies for other architectures. In all, virtual dedicated server hosting acts as a bridge between shared web hosting services and dedicated server hosting services. The biggest advantage of using virtual private server hosting is its cheaper cost, in comparison to a dedicated server.

A virtual private server hosting generally runs its own copy of operating system with customers having super-user-level access. Above all, in virtual private server hosting, you can easily install almost any software that runs on the OS. At times, certain software does not run well in a virtualized environment. This includes firewalls, anti-virus clients, and even the virtualizers.Having said that, Arachno Net provide their virtual private servers, complete with raid disc mirroring, a secured /tmp directory, firewall and brute force detection system already installed.

Recent time has witnessed the massive increase of the number of virtualization clients. These virtualization clients, usually, run on a single machine. A virtual private server web hosting generally has limited processor time, RAM, and disk space. You will be surprised to know that at times virtual private servers are also employed as honeypots. These honeypots allow a machine to purposely run software with known security flaws. They, of course, make sure that it is done without endangering the rest of the server. Multiple honeypots can be quickly set up through virtual private servers in this fashion.

While choosing a virtual private server hosting company, ask the following questions. Finalize your selection only if you are convinced:

1. What are the specifications of the host server, that is, the RAM, CPU, and network throughout?

2. How many virtual private servers are run on the host server that you'll be on?

3. How is resource contention handled? In other words, what happens if all the other virtual private servers on your host server are running CPU/RAM-intensive processes?

4. Last but not the least, do you have a dedicated minimum amount of RAM/CPU/Network usage? If so, how much?

All these questions are satisfactorily answered by virtual private server hosting provided by Arachno Net. Arachno Net provides network monitoring, daily data backups, 99.7% uptime through multiple oc3 Internet connectivity, and backup power UPS and generators.

Secure Your Own Bandwith With a Dedicated Server

If you are serious about your online business endeavors, you might just consider looking for an online dedicated server. The dedicated server is actually an entire server which is at your disposal, and which is not shared with anybody else.

Right from the start, the advantages are clear: you, as the webmaster, have full control over the server, including option of operating system, hardware, etc. You can customize everything according to your own personal needs, while the administration is still handled by the hosting company.

The most important advantage of using an online dedicated server is that your website performance will not be affected by the traffic of the other websites with which you would have been sharing your server's bandwidth.

The online dedicated server environment provides an exclusive server or servers devoted to the sole purpose of serving yourself only. You do not share hard disk space with other customers, and you avoid shared hosting.

Before dedicated servers existed, a web site developer used to have two hosting options, the low-priced shared hosting model and the premium-priced dedicated server. A person who bought space on a shared host would get a certain amount of disk space and monthly transfer, and would have the web site served from a common web server.

The hosting company would attempt to provide a wide range of options for the web site developer, in order to increase the popularity of their products. But, for example, if a customer needed a non-standard program installed or maybe wanted to use a privileged account in order for a particular utility to run, he would be completely not allowed to achieve these goals.

A simple example might be a site which required a database to store the information in. Many hosting companies provide the standard MySQL database to use on their servers. If your application requires another type of database though, then it could prove to be incompatible with the shared hosting account.

And a dedicated server can be customized anyway you want. But, there's also a catch. Because it can handle much more traffic than a shared hosting account, their much better performance doesn't come cheap. A typical dedicated server can cost the savvy webmaster hundreds of dollars per month depending on its size, network connectivity and the amount of management required from the hosting company.

Webmasters who don't fit into the standard shared hosting model and find that it doesn't work anymore for them, or whose sites grew very popular and required a large amount of resources have the alternative of a dedicated server. It can be customized to exactly fit the needs of you as a site developer. And as long as your business is very successful, you are probably way better with a dedicated server at your disposal.

Dedicated server is better than shared server

Web host company offers two options such as shared server space or dedicated server at the time of leasing server. Dedicated server is a single web server within a network of computers that is dedicated only to one customer. Mostly large businesses use dedicated servers because it satisfies the requirements of large businesses due to several reasons.

Dedicated server is best option instead of shared server because it enables you to install data applications. It offers full control over server operating system and enables the customers to customize hardware as well as software setup to meet exact requirements. Web host provides hardware of the computer, network connectivity and routing equipment with dedicated server whereas client controls and maintains server software.

Dedicated server is the best option for the people who want huge amount of data space and bandwidth. These servers offer complete control on entire network. Major advantage of dedicated servers is that it provides each and every service at the small cost. Sometimes it enables the clients to install desired software with superior flexibility and administrative options. The clients don?t share resources in dedicated server.

These servers offer ability to manage firewalls and password access due to security purposes. Basic requirement to have a dedicated server is technical skill. A person with a great technical knowledge can easily handle all problems of dedicated servers. Dedicated servers are costlier than shared servers.

Dedicated servers are categorized as managed dedicated servers and unmanaged dedicated servers. Several things such as operating system, hardware options, space and bandwidth are such options that should be considered while selecting dedicated servers .
