Linux Load Balanced Servers requires a cluster of dedicated servers that can be designed to work together to share the load of a website or application that is the common link between these servers. Often the servers that form a load balancing cluster are of a high specification as websites that receive high volumes of visitors require powerful backbones that are capable of supporting every request that the website receives. Load balancing is applied to web servers more often than not because this is where a majority of requests are made to and in most situations there isn’t anything that can be done to reduce the impact of requests for web pages and scripts, but alterations can be made to database/SQL statements to reduce the number of database queries that are made in a single page request.
A load balancing cluster requires at least two web servers and two database servers so that the loads can be spread evenly; a further server is required to act as the ‘load balancer’, which will route traffic as required to the server with the lowest load at that point in time. The second database server in the cluster won’t be actively accessed, instead with the first database server being the only actively accessed database host and the second server being in place for backup purposes.
Benefits of Load Balancing
Scalability is important when developing a large website because otherwise you could face downtime and for many businesses this can introduce the element of lost revenues, therefore making the investment of a large and stable hosting infrastructure a justifiable necessity. Host.co.in offers a range of different load balancing solutions that you can take advantage of how you wish so that you can provide your website with a suitable platform on which it can be hosted. There are many benefits to choosing a load balancing configuration, including:
As well as being a suitable solution for distributing the load placed on web servers, load balancing is a solution that can also be introduced to a number of other services and applications that you can use in the server environment. Linux server-based load balancing is most suitable for web servers, although network-based load balancing allows you to introduce the use of different protocols so more advanced applications can be scaled through load balancing.
Load balancing is something that can be configured for you by bodHost’s 24×7 support team when you purchase at least two dedicated servers from us. Our support team is fully knowledgeable in all areas of server management so you can be assured that the load balancing cluster put together by us will meet your expectations in terms of scalability and stability.
Unfortunately, not all search bots and spiders comply with robots exclusion rules; nor do they have to either. While we’re not lawyers (and we could be wrong), as far as we’re aware, there is no U.S. law prohibiting search engines from ignoring robots.txt exclusions on websites. However, that doesn’t mean there’s no point in using them; as most of the major search engines comply with the robots.txt exclusions, including Google and Bing/Yahoo!
We have suspicion to believe Baidu, a popular search engine in China, does not comply with robots.txt exclusions. However, some smaller search engines worldwide may also not comply with robots.txt exclusions.
The only plausible way to prevent is likely to blacklist their IPs on your Dedicated Server or your individual hosting account. You may also need to blacklist an IP range in order for it to be more effective. Otherwise, password-protect the specific directory.
PHP is one of the most widely-used server-side scripting languages for creating dynamic web pages and web applications. Some of the most popular web applications including forums, e-commerce shopping applications, content management systems and blogging applications are developed using the PHP programming language. PHP is incredibly easy and simple to learn but has a huge array of features for the most complex applications you’d need to create. A few prominent examples of popular PHP applications include WordPress, being one of the largest blogging software used in the world; phpBB, a popular bulletin board software and Joomla, a popular content management system (CMS) developed in PHP (among others).
PHP originally started as a simple set of tools for web developers to be able to use in order to automate and simplify certain tasks. Although originally, Rasmus released PHP as the “Personal Home Page Tools”; and it had. very limited and basic functionality and were originally simply a set of Perl scripts for his personal website. However, later on he rewrote those Perl scripts as CGI binaries in the C language with more features including the ability to process form input and a few other things – and he had renamed the language toolkit to “Personal Home Page/Forms Interpreter”, commonly shortened at the time as “PHP/FI”. The first version of PHP/FI, version 1.0, did have some basic features that are still common to PHP today, including variables (that has syntax similar to that of Perl), dynamic form handling, and could (as it can today) have HTML embedded in the PHP file.
In 1997, Zeev and Andi, at Technion IIT (a public research university in Israel) rewrote the PHP parser, and PHP 3 came with some useful new features; one of which being basic support for object oriented programming – and until PHP 5, object oriented programming support in PHP wasn’t favourable in comparison to other languages; especially considering PHP 3 and PHP 4 essentially had partial support for all of the models in object oriented programiprogramming, such as visibility of methods and class-level properties/variables only being available since PHP version 5. Object oriented programming is a programming and development model in which code logic is separated into different methods and with features in object oriented programming such as inheritance, abstract classes and more; it can make application development easier especially for large-scale applications.
PHP 5 also introduced PHP Data Objects, a simple, object-oriented way to interact with database systems. It’s similarly an alternative to using the standard database functions such as mysql_query() for MySQL databases and pg_query() for PostgreSQL databases.
Even though PHP is designed for the creation of web applications, it has plenty of interesting and useful features, including:
You can dynamically create images using PHP by simply writing PHP code. – images are drawn using the Graphics Draw (GD) library. An image is then rendered by PHP saved to the server.
You can compress files using PHP to various compression formats, including .zip, .rar and .bz2.
You can check the strength of passwords using built-in PHP functions – there is a cryptography extension Crack that allows you to test the strength of a password.
Bodhost’s Linux dedicated servers are offered with the choice of cPanel/WHM and Plesk if you require a web-based control panel through which you can manage your dedicated server and any hosting related services, for example clients and web hosting plans. As the only other method of management available to you as a Linux dedicated server administrator is through SSH, a web hosting control panel is strongly recommended as an addition to your hosting package so that you are able to fully utilize the features and power that a dedicated server can offer.
The most popular control panel for Linux servers in any case is cPanel; not only is cPanel a low cost control panel suite, but it is also uses system resources efficiently to ensure that your server remains stable, even when under load. Some of the core features of cPanel include:
cPanel is often seen as being the most complete solution available to Linux system administrators and is the ideal platform for anyone with a Linux Dedicated Server who is looking to start their own web hosting business. Like any other web hosting control panel, cPanel offers the facilities necessary to create and maintain your own web hosting clients, based around your own web hosting plans.
We here at Bodhost can also offer you the Plesk control panel for your Linux dedicated server, but we don’t feel that this can offer you the same benefits and features as cPanel. Along with Plesk, we can provide installation services for any control panel that you wish to use on your Linux Server.
With our Windows dedicated hosting plans, you will find that you are more limited with the choice of control panel offered by Bodhost as we only support Plesk on our Windows servers. However, you shouldn’t let this change your mind about choosing Bodhost as your Windows dedicated hosting provider because Plesk is one of the most feature-rich web hosting control panels available for the Windows platform. Some of the features offered by Plesk that you will find useful include:
If there is another web hosting control panel that you would like to use with your Windows dedicated server then you should contact Bodhost’s 24×7 support team as they can offer assistance with the installation of a number of different applications; however, it should be noted that you will need to purchase and supply your own license in the case of commercial applications.
The shared cloud is offered to promote affordable cloud hosting that is accessible to users of all abilities and businesses of any size so that they are able to reap the benefits of the reliability and security that the cloud platform can provide. eNlight cloud hosting from Bodhost utilizes one of the core principles of promoting affordability in the shared cloud – the pay-per-use concept; the definition of ‘pay-per-use’ in this context is that you will be paying for the resources that you wish to have allocated to your server or are using and nothing beyond that. Furthermore, the eNlight platform allows for the expansion of virtual machines with just a few clicks so that resources are assigned immediately; with this feature we can assure you that no downtime will be incurred when adjusting the resource arrangement on one of your virtual machines.
Offering low unit prices for each of the resources that form an eNlight virtual machine is another feather in the crown of the platform; although affordability can be achieved by allowing customers to specify the units that they require of each individual resource, it is important to offer competitive resource pricing so that even customers with low budgets are able to obtain a reasonably powerful VM for the price. The major benefits of the enterprise cloud hosting can also be whittled down to:
More often than not even the largest of businesses won’t be able to fully utilize what a private cloud can offer in terms of capacity and the shared cloud often has more than enough clout to offer – Bodhost is always adding additional capacity in the form of extra hardware to ensure that our eNlight clusters are able to improve the performance of their virtual machines then necessary. Auto-scaling is also available for situations where demand can’t be predicted and where you may not be in a position manually increase the resources of your virtual machine(s); auto-scaling will automatically allocate the resources that your VMs require to remain stable when they are put under a high load, with these additional resources then withdrawn once demand subsides.
As an enterprise web hosting company, Bodhost is able to offer one of the best shared cloud platforms in the US and we believe that our cloud hosting plans are some of the most affordable and offer a number of additional benefits over traditional web hosting plans. Even though the cloud may be a more expensive endeavor for some, the additional cost is there to cover the extra hardware that is used to provide a stable hosting environment; traditional web hosting plans that use single-server configurations often fail to meet an uptime level of 99.95% because there is no redundancy in place to handle server failures.
Cloud computing as a technology is being slowly adopted by businesses of all sizes because it allows for the centralized storage of documents and application data so that users are able to create a consistent experience between all of the devices that they use to access the cloud, whether these are computers or mobile devices. In the context of web hosting, the cloud introduces the concept of having full control of your virtual machines along with other external factors; IaaS (Infrastructure as a Service) platforms such as eNlight not only provide you with virtual machines, but these VMs can be adapted as you see as necessary and you can adjust external settings and setup features including firewalls and vLANs between eNlight VMs.
For an unmatchable enterprise cloud hosting experience, you should look into Bodhost’s eNlight hosting services and see how USA cloud hosting can save your business money.
