The server cluster is the system where you can use 2 or more servers to give a solution in a shorter time. The great first advantages of using this kind of technology is that having two servers working on the same problem defines more efficiency and cutting the solving time.

Many companies are increasing the amount of resource-heavy applications and requiring increasingly massive processing power to manage their systems… yet still rely on obsolete, single computers to do all the work.

For problems of malfunction on some of the computers in the cluster, automatically the work is distributed to the other computers in the cluster. This is more efficiency on problems caused by hardware or any other component problem.

Technology-savvy companies know that a server cluster actually saves them money. So instead of spending their IT budget on many single mainframe systems to process their information separately, they decide to invest in a single powerful central unit to handle all of it at the same time, with more precision and speed.

This is the great solution, because this is more efficient process to solve the speed and management problems of elements and information stored in single servers, processes where need more processing that the one that provides a single and powerful server.

A web hosting control panel is a web-based platform which is able to manage one’s web services under a single location. It can mange email accounts, FTP accounts, disk space monitoring, create backups and bandwidth monitoring. The web hosting control panels gives a unique solution to Linux newbies to host multiple websites on VPS and dedicated servers. The web hosting control panels give a unique solution to Linux newbies to host multiple websites on VPS and dedicated servers.

There are some most preferred open source/paid control panels:

1. cPanel
2. Plesk
3. ISPConfig
4. Ajenti
5. Kloxo
6. Open Panel

Which one to go? : –

cPanel is a Linux-based web hosting control panel with an easy to use graphical interface and automation tool suite which is designed to make website hosting simpler. It functions according to the needs of administrators, end-user website managers.

Plesk provides the ability to configure and maintain Windows or Linux servers. WordPress tools make use of Plesk12 enhanced server to site security features.

The features of control Panel are:

1. Common line access: Plesk and cPanel both offer command line access. cPanel has API-based access and command line access both. Plesk has command line access tool called the Panel Action Log Command Line Access tool.
2. Removing Panel: Removing cPanel requires reformatting the server and reinstalling the OS. To remove Plesk Uninstall scripts are available.
3. Ease of use: cPanel collects functions into high level groups that include preferences, files, logs, domains, security and software services. Plesk is divided into functions that has statistical and resource usage, websites, mail, application and statistics.

Benefits:

Plesk control panel is provided with Windows. It is cost effective and allows users to automate tasks and upgrade components easily at times automatically. For host servers it is secure platform than cPanel. Technical support for Plesk is easier to understand and not very technical in comparison to cPanel. Plesk can be used for both Linux and Windows servers, whereas cPanel can be used mainly with Linux web servers. Plesk works on a cloud where several servers and sites are there. The stability of Plesk control panel is appreciable as with the use of Plesk it is very easy for anyone to manage multiple accounts on one single server.

What Plesk lacks:

Plesk has some disadvantages:-

1. Difficulty in big tasks: It is very difficult to complete a big task such as many thousands unique files from a directory which have to select and move slowly.
2. Fixing permission issues: It is difficult to manage and check permissions of files which have changed through control panel.
3. Server security: The control panel is based on the server and relies easily in software and hardware. So, there is a chance of DDOS attack easily.

Conclusion:

The right control panel makes a large difference for users. Plesk and cPanel both have great features and are similar in many functions. They both have different security methods which are used in different ways.

For dedicated server, user has to manage and take care of that server. A person purchasing managed dedicated server hands over all technical and support issues to the provider. User can either choose a managed server and hosting company handle all the details, maintenance and updates. User can manage the server by himself.

Few things are there which has to be considered into buying a dedicated server:-

Fully Managed Hosting:

It means the server is managed by hosting company for user. Server management has following services:-

1. Server monitoring
2. Server security covers virus scanning, software firewall configuration and spam filtering.
3. Database Management
4. Storage Management

Data Center Facilities:

While buying a dedicated server, it is of main concern that what facilities are being provided. Some of important features to check among data center services are:-

1. Power Redundancy
2. On-site Security
3. Cooling systems
4. Redundant bandwidth

Remote Reboot Capability:

Remote reboot provides the capability to restart a server from a remote location without the need to call the hosting company. IPMI (Intelligence Platform Management Interface) is a service to do remote power management for user’s servers.

Content Delivery Network:

It is an efficient and fast delivery of content over website. A CDN allows website to replicate over multiple different locations like Asia and Europe. If somebody from Japan access any website, a CDN server from Asia will deliver the request and if somebody from Spain access any website, a CDN server from Europe will deliver the request.

Technical Support:

Most of the companies’ offer 24/7/365 technical support via phone or live chat. Technical support number must be readily available if any sudden server crash/failure or any technical disaster occurs. There should also be some tutorials and guides available for users to troubleshoot some errors themselves.

Few basic protection tips:

Any users who is using dedicated server hosting soon find some responsibilities on host provider. Some protections are:-

Passwords: On switching to dedicated server, a password change is necessary. User has to change password immediately. User has to remember following:-

• Make password more cryptic. User has to choose some collection of letters, symbols and numbers.
• User can also use a random password generator as it does not recommend using passwords which consist of dictionary words.

Better Security: The web server security depends on ability to identify interruptions during internet access of its ports. To prevent from unauthorized access, a firewall provides control over incoming traffic. Virus can easily infect the server which can be catastrophically impossible to cure. Every server is always vulnerable to sudden illicit attacks so it is better to prevent them by applying security measures. For e.g. Firewall security, Antivirus etc.

Keep Current Software: Most software manufacturers monitor new security loopholes and introduce updates to deal with security liabilities.

Update OS with latest patches: User has to make sure that OS is running with latest installed security updates. This will help in minimizing the risk of dedicated server. Most Linux distributions keep informed their users of new updates.

Backup: At some point, there may be some data lose. So, user has to perform regular backups with databases, configuration files, dynamic files and logs, resident customer files.

Conclusion:

Most users are comfortable in handling their operations in dedicated server management. Some services such as OS update, software update, managed backups should be included in managed dedicated server plan. There is a necessity of security precautions that should never decrease the importance of running dedicated server.

A clustered approach to web hosting can take the sites to a new level as it overcomes the limitations of one physical server. Even compared to the finest dedicated server plans a clustered approach is still far superior. Grid web hosting technology or the clustered dedicated servers allows sharing of processing powers amongst many servers, distributed in real time. This means that the websites are powered by a very powerful and inexhaustible source; it is because even the largest customer cannot take more than a tiny fraction of the large server pool. The other benefit is that, if one server is under threat there are lots of back us available and the other servers are available to share the load.

Clustered web hosting is structured in such a way, that the intrinsic errors are eradicated. These errors are generally found in shared hosting system, this means grouping of a number of servers and then networking them so that the work stack can be shared. Clustered web hosting is the site that caters to this service. In this case the resources of the websites are drawn so accurately that a particular web site is not confined to only one server. The consistency of the server is maximized as all web sites have their own service redundancy.

This involves sharing of a numerous servers, sharing of their programs, and also distributing it during active time. Whenever there is a change in a clients account, then this information is speedily transmitted to all the servers that are present in the clustered dedicated server. There are a lot of advantages of clustered dedicated servers.

In the ordinary hosting situations, the security tiers are not generally incorporated in the platforms. Hence most of the hosts have to implement the firewall method to overcome this weakness. But this is not the case with clustered dedicated servers; in this case there are many levels of security. The network of a clustered web hosting has excellent routing and switching structure; it has an inbuilt fire wall and also has a proxy tool. This keeps the clustered web hosting one notch higher than other traditional hosting techniques

One’s single office connection is not enough to host a web server now an important question which arises is which is best, leasing a dedicated server or buying own server and co-locating someone\’s data center?

Distinction

If one is unsure of the difference; here it is in a nutshell. If one co-locates, it simply means renting space within someone else\’s facility to store his/her own server or servers. It is very much similar to a high tech gym locker that user is renting all or part of house his/her servers. The user either ship or deliver the server to his/her provider. Additional services that are provided by the host along with co-location differ from individual to individual host but it surely will not include the actual server. With a dedicated server the user will get all the features of co-location, as well as, the actual web server itself.

Which is superior?

Between web hosting and co-location web hosting, the best would be which is best suited for one’s need. Comparing both we will find that there are excellent situations for both the dedicated server option is quickly becoming a better choice in more and more cases. If one already possesses a web server, or prefers to use cluster, then obviously co-location possibly will be the user’s ideal choice. If the user is bearing in mind buying new equipment and shipping it off for co-location, he/she should reassess. One should know that, the prices and equipment existing in dedicated hosting currently are outstanding, not only this but it will relieve the user from the burden of hardware. Most hosts prefer to carry suitable spare parts on hand according to the servers used, so that quick action can be taken if any undesirable thing happens. Depending on one’s arrangement with a collocation deal hardware failure could simply mean paying extra to have a server shipped back, having it fixed by oneself rather then sending it back to the data centre.

Now we get to know that what is dedicated hosting and what its needs are. Firstly, it is worthwhile to note that dedicated server is quite an expensive service and so its optimum utilization is must. By maximum utilization of a dedicated server a business owner can run a successful business but this statement will be only considerable when we will present this statement with facts, which are as under.

Freedom and security
Above all of the conditions customer firstly wants to security as well as freedom and this can only be achieved by way of dedicated server. The best part of dedicated server is that now there is no need to share it with web sites. Further facility provided by dedicated server is that it gives customer the additional third party security for its sites and emails. It also enables deep access to its user’s server so as to configure it and optimize it in a way required. It also helps in selection of software that needs to be installed.

Power and functionality

User can get 50 to 100 GB of hard drive by dedicated server and also approx.1, 000 GB of data transfer. According to user’s requirement he can customize the configuration and chose any CPU RAM. With the help of dedicated server dependency on web host tends to decrease as well as time delays tends to do down steeply thereby making it more economic in future.

Respectability
It’s not worthwhile to run a popular website on a shared hosting. It’s not acceptable.

If you want to know difference in dedicated hosting and co-location web hosting then co-locate, you are simply renting space within someone else\’s facility to store your own server or servers. It\’s like a high tech gym locker that you are renting all or part of to house your servers. You either ship or deliver your server to your provider. Additional services provided with co-location vary from host to host but it certainly won\’t include the actual server. With a dedicated server you are getting all the features of co-location, plus the actual web server itself.

If we concerned about better one then it certainly depends on your particular needs, and there are excellent situations for both the dedicated server option is quickly becoming a better choice in more and more cases. If you already own a web server, or cluster that you prefer to use, then obviously co-location may be your best choice. If you are considering buying new equipment and shipping it off for co-location – please reconsider. The prices and equipment available in dedicated hosting these days are outstanding plus relieve you of the burden of hardware.
