Dedicated Server hosting
This form of hosting allows customers to lease pre-configured, high-end equipment and connectivity from the provider. Offering greater flexibility than shared hosting and less responsibility than colocated hosting, the customer generally retains control over their hosting environment. They choose their operating system and software and tailor it to their needs. The provider, however, remains responsible for administration.

Customers using a dedicated server hosting solution require an overall competency in IT and server administration issues. It also requires a more significant investment of finances, time and human resources than shared hosting.

Shared hosting
Sometimes known as virtual hosting, this is the most basic and the most inexpensive of hosting alternatives. With shared hosting, numerous customers host their websites on one server, sharing the cost of an Internet connection that’s generally faster and more secure than dial-up connections. An range of basic bundled services at a low monthly fee makes this a popular choice for first-time webmasters.

While economically sound, this type of shared hosting typically cannot handle large amounts of storage or traffic and the provider offers little to no IT services or flexibility.

Colocated hosting
For webmasters who desire complete control over their server, colocated hosting is an option. The provider offers only space for a server on their rack and usually a low performance bandwidth. The customer is responsible for everything else — purchasing, configuring and maintaining the physical hardware (servers, firewalls, etc.), software and the operating system.

Setting up and maintaining a colocated server is not a simple undertaking. It demands that the customer have a great deal of IT expertise and time. Any extra services or assistance by the provider also incurs extra costs.

Hosting often uses its own language, or languages, comprised of acronyms, proprietary names and terms that have been granted new meanings. For some it’s a first language. For others it’s an entirely new language. This abridged glossary is designed to assist in “translating” the more common hosting terms into more common language.

Apache
One of the world’s most popular Web server programs, Apache was built by a group of open-source programmers and is often used because of its outstanding performance, strong security features and the fact that it is free.

Application Infrastructure
The software components that your custom application relies on for its functionality. Examples include web servers, application servers and database servers.

Bandwidth
The amount of data that can be transmitted at a given moment to a server. The higher your bandwidth, the larger amount of traffic your site can handle at one time.

CGI
Short for Common Gateway Interface, a small script that processes data taken from the user (such as from a form application).

Cgi-bin
The directory on a web server where CGI scripts are stored.

DDoS
Short for Distributed Denial of Service Attack, the most common form of attack on network devices. It overwhelms a network by monopolizing its bandwidth by flooding it with information from multiple hosts, thereby preventing legitimate network traffic.

Device
Refers to the individual hardware components that make up a unique hosted configuration. This includes servers, firewalls and load balancers.

Firewall
A piece of security software or hardware designed to protect web servers. They are typically used to protect sites from hacker attacks/unauthorized access.

FTP
Short for File Transfer Protocol, a method of allowing remote users and Web servers to exchange files.

HTML
Short for HyperText Markup Language, the language by which web servers and client browsers communicate. All server-side functions (such as database processing), although they may be performed in another language, must eventually be output back to the user in HTML.

HTTP
Stands for HyperText Transfer Protocol, the protocol by which HTML files move across the Internet. HTTP requires a client browser and an HTTP server (typically a web server).

IDS
Short for Intrusion Detection System, it recognizes all types of hostile network traffic and computer usage that can’t be detected by a conventional firewall.

IIS
Short for Internet Information Server, Microsoft’s server software for Windows NT/2000.

IP
Short for Internet Protocol, which designates the format of “data packets” that are used to exchange information over the Internet.

J2EE
Short for Java 2 Platform, Enterprise Edition, J2EE is a programming platform for developing and running distributed multi-tier architecture applications, based largely on modular components running on an application server.

LAMP
An acronym for a set of free software programs commonly used together to run dynamic Web sites:

* Linux, the operating system;
* Apache, the web server;
* MySQL, the database management system (or database server);
* Perl, PHP, and/or Python, scripting languages.

Load Balancing
Distributing data across a network of servers in order to ensure that a single Web server does not get overloaded with work, thereby affecting performance.

Managed Backup
Refers to the copying of data for the purpose of having an additional copy of an original source, specifically storing data on separate tape media not located on the server. If the original data is damaged or lost, the data may be copied back from that source.

Name Server
A server responsible for translating domain names and IP addresses.

NOC
Short for Network Operations Center, a hosting company’s “home base,” so to speak. The NOC is usually where most administration, technical support and physical server storage takes place.

Packet switching
The method by which most data is exchanged throughout the Internet. Most data is broken down in to smaller “packets” prior to transfer, and then reassembled at the destination.

RAID
Short for Redundant Array of Independent Disks, a method of data protection/backup. Data is stored over a number of servers so that information will still be accessible if a piece of hardware/software crashes.

SAN
Short for Storage Area Network, a network designed to attach computer storage devices such as disk array controllers and tape libraries to servers. In a storage network, a server issues a request for specific blocks, or data segments, from specific disk drives. This method is known as block storage. The device acts in a similar fashion to an internal drive, accessing the specified block, and sending the response across the network.

Scalability
The ability of a piece of software or hardware to expand/grow as necessary.

Service Level Agreement (SLA)
A formal written agreement made between two parties: the service provider and the service recipient. The SLA itself defines the basis of understanding between the two parties for delivery of the service itself. The document can be quite complex, and sometimes underpins a formal contract. Generally, an SLA should contain clauses that define a specified level of service, support options, incentive awards for service levels exceeded and/or penalty provisions for services not provided.

SQL
Short for Standard Query Language. A standard protocol used to request information from databases. Servers that can handle SQL are known as SQL servers.

SSL
Short for Secure Sockets Layer, a protocol developed by Netscape to handle and protect confidential/sensitive information required for e-commerce transactions (like credit card numbers). SSL addresses usually begin with ‘https’.

VPN
Short for Virtual Private Network, a private communications network usually used within a company, or by several different companies, to communicate over a public network.

Web Hosting
Web hosting is a service that allows users to post web pages to the Internet. A Web host, or hosting service provider (HSP), is a business that provides the technologies and services needed for Web sites to be viewed on the Web.

XML
Short for Extensible Markup Language. XML is a language allowing developers to create their own markup tags. All XML tags are defined by the programmer, and can be interpreted differently in different applications. For example, the “” tag in HTML means Italics, but could mean anything in XML, depending on the function the developer assigns to it.

The Internet Exchange Messaging Server (IEMS) is a highly modular and scalable open architecture messaging system. It can be used from small single machine installations to fully distributed systems linking geographically distributed sites into a common set of logical domains. Its various components can be run on a single machine or in a distributed environment. Administrators can install IEMS on Windows 98 and ME (Anti-Virus Detached Machine), NT, 2000, and XP. For Linux administrators, IEMS can be installed on RedHat Linux 6.2 through 9.0; Mandrake 8.2 through 9.1; SCO Linux Server 4.0 (United Linux 1.0); RedFlag, and Cosix (CS&S).

A technical introduction and specifications to IEMS can be found here. In additional all IEMS Documentation is freely downloadable.

Internet Exchange Messaging Server totally integrating spam detection, handling, and decision making across the entire messaging system - from connection controls through to the end user mail client. IEMS spam control measures include SMTP connection controls (site and Internet blacklisting), mail relay, MTA level content analysis, user mail sorting, and user directed Bayesian filtering. Site administrators are able to define site wide spam security policies, while deferring decisions on many of the spam detection methods to the end user, including SMTP connection controls.

This combination of SMTP controls, Content Filters, Bayesian Filters, DNS Blacklists, and the integrated extension of these controls to the end users allows for an extremely flexible protection system, designed to block the maximum number of problem messages with no collateral damage.

Some of the many features include anti-virus scanning, attachment filtering at the MTA level, distribution list manager, batch SMTP, connector modules to legacy mail environments such as Lotus cc:Mail and Notes, and more. Messages can be retrieved from the IEMS Message Store using any standard POP3 or IMAP4 capable client (Outlook Express, Eudora, Evolution, etc), as well as the customizable IEMS Web Mail Client. The Web Mail client also supports private and public address books as well as online file storage through web folders. IEMS also supports Outlook compatible calendaring and scheduling, allowing for a natural migration path from Microsoft Exchange.

IEMS is licensed in either Standard Enterprise Edition or Professional Enterprise Edition modes. Both editions are identical in terms of functionality with the exception that the Professional Enterprise includes cc:Mail and Lotus Notes connectors and also has the ability to operate across distributed systems.

IMA provides a free public test environment you can log into now to get an immediate feel for the power and flexibility of IEMS or you can download your own copy and test it on your server for free for 30 days.

What is SSH ?

SSH or Secure Shell is a suite of programs which provide encryption of sessions between computers. It is a secure replacement for telnet, rlogin, rsh and rcp.  The encryption begins before the username/password  conversation starts thus providing a mechanism for no plain text passwords traveling over the intra/internet.  Secure Shell also provides a better means  of authenticating host computers helping to prevent address spoofing attacks. The main features of SSH include secure remote logins, terminal emulation, fully integrated secure file transfers, and secure tunneling of X11 traffic.

SSH Clients

SSH clients exist for all common architectures and operating systems. Some are free, some are shareware or commercial versions.

SSH Clients for Unix/Linux

* OpenSSH is an SSH v1.x and v2.x compliant SSH package that is freely usable and re-usable by everyone under a BSD license.

With Dedicated Servers you get full root ssh access. You have complete control over the server administration and specifications.

Linux Dedicated Server Web hosting is a fast, stable, reliable, and free operating system for a website, which operates faster than other similar dedicated servers, according to information currently available on the Internet. If a website owner wishes to purchase the program on a CD instead of downloading it from the Internet, the purchase price is about £20. An important feature is, this that the Linux Dedicated Server system is open-source, meaning the source code is readily available to anyone who wants it. This availability has resulted in improvements to the system from multiple contributors that insure a very stable operating system and high uptime.

Managed Linux dedicated servers such as Linux web hosting provide clients with a top-ranked environment to host mission critical and resource intensive web sites. They include ecommerce and database applications, corporate information systems, email, and groupware applications. Anyone looking for the power and freedom of administering and running their own dedicated web server remotely, there are unmanaged dedicated servers from Linux. Most people using this brand of program for host service will have a company actually doing the hosting duties, which are many. These services should include monitoring and management seven days a week, twenty-four hours a day. Version management should be part of their service so the website owner is kept up to date on the version of the program that is in place and what other versions might be available. They should be able to plan for expansion so there is no shortage of space available.

Managed Dedicated Servers

People might be thinking about managing their own dedicated server. Before making a decision to do so they should check out the hosting packages online on fully managed dedicated servers. This will save some headaches in maintenance. A hosting service will manage and keep it up and running. Most sites offer support for technical problems pertaining to any kinds of site issues. Hosting packages range in price depending on the customized features offered. Choosing faster processor speeds and more memory will end up costing more than just the low-end basic service. However, the basic service will provide the designated dedicated server hosting with a good processor speed and adequate memory.

When choosing a web hosting service, individuals should evaluate the site for effectiveness. The functionality, traffic, and available services must be closely examined. Of course one must consider a budget when it comes to web hosting services. Weigh the differences in cost to having a dedicated server verses a full one. With managed dedicated servers technical issues will be taken care of by the hosting service. Any hardware or software issues are usually also included with technical support.

Using managed dedicated servers for a website will provide a service that will allow people to concentrate on the more important aspects of a business. Some companies that offer web hosting server management also offer tips on marketing techniques. Some include marketing packages along with hosting services to help the new business owner with initial advertising. Do some research on fully managed dedicated servers and find a reputable company that offers reasonable prices. Become informed by reading frequently answered questions on various sites and if not sure about some issues, make some phone calls using available contact information or do a live chat with a professional. This will help clear up anything people may be concerned about. “Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.

cPanel Dedicated Server

The cPanel essentially is a control panel system that hosts data on the web. This system is installed on, what is known as, a dedicated server. It must be remembered that cPanel does not have any billing service. One has to physically register clients and deal with their payments manually, using an external service provider.There are essentially two sides to this cPanel dedicated server system:

1. On the one hand there is the Web Host Manager or the WHM for whose who host the content on the web: the function of the WHM is basically to insure that the functions of the system and control panel are performed safely through the right interface. It also helps in easy administration of the hosting accounts and the reseller accounts. The good part about this is, however, the WHM does not require performing functions like manually set up user accounts, deal with their passwords and inbox, etc.

2. And on the other end is end user who uses the cPanel: it is the end user who ultimately uses the cPanel which allows them the liberty to administer everything on their own account, creating accounts, elimination accounts, clearing emails, etc.

Receiving a cPanel server:

Not all dedicated servers purchased or leased through server providers come with a cPanel system. However, while looking out for a dedicated server to purchase, one must necessarily go for a cPanel dedicated server. If cPanel is purchased with the server, there are chances of gaining a good discount on it. Web Hosting UK (webhosting.uk.com) is the popular cPanel partner Network Operating Centers. The cPanel can, however, be run on Linux.

Using the cPanel dedicated server:

The cPanel dedicated server would require to be initialized before one can start off with the publicity and client servicing bit. The following steps would give you an idea of how to go about the initialization:

1. Name servers must be set up.
2. Server protection must be gained by tuning security settings.
3. Verification for effective operation of all services must be done regularly.
4. Ad-on scripts to forward to clients may be included.
5. Security scripts can also be included.

Miscellaneous to keep in mind:

It must be remembered that cPanel does not have any billing service. One has to physically register clients and deal with their payments manually, using an external service provider.

Dedicated server vs Shared Server:

Most people pick dedicated servers, this could be because they have some experience using this services or they already read some stories about this content. If we think logically on the word “shared” this drive us directly to the knowledge that we share some concepts of the server.We hope that the server we share is totally debugged and with zero problems, we don’t want any kind of downtime on our website, this is never sure for shared websites.

So why is better the dedicated server, you principally have total control on your website, also you can install any kind of application, you can update any kind of software or hardware in your server, it’s made by your specific requirements and only for them.

Also, this option is great for people that need to upload huge amount of data, and need great capabilities for bandwidth.

For the dedicated servers we also can provide the capabilities to manage firewalls and password access, this is for security purposes. If you have big knowledge on dedicated servers, can control any kind of problem
