Linux Server

Selecting the right server from the numerous ones available is a highly important task. The selected server must be the one best suited to meet all the needs. The selected server should support the current work requirement as well as those which are being anticipated tomorrow. The server should provide the required connectivity with other devices. It is always best to have a server solution which is customizable. The most important factor to be checked is that the server should maintain a level of operating security that is required by the business. A server selected considering these conditions will provide the best performance. The selection of a server is dependant on the applications expected to run on the server, budget and technical complexity involved in setting up and maintaining the server.

People who want to customize the system especially the developers generally go for Linux servers. The advantage of going for a Linux server is that the underlying code can be modified and can be used on a wide variety of platforms. Another option of selecting a server is to go for a remote server service.  The various factors that need to be considered while selecting a server are speed, large storage capacity, reliability and security. As a server is expected to provide services to many client computers at once, speed of operation is an important factor. The server should have plenty of disk space if it is to act as a central storage repository. Servers should be reliable as any breakdown can result in heavy loss. The server should be having a lockable case of physical security along with a software security against malicious hackers. It is always desirable to go for a server having warranty and service agreement. The server chosen should be of suitable form factor. Form factor refers to overall size and shape of the server.

A server operating system is designed for stability, reliability and security. The choice of operating system is determined by the use to which the server will be put. In general the choice of server operating system is dependant on familiarity with OS, total cost of ownership and compatibility with any application to be run on the server. The server processor should be capable of handling the operations. The processor varies depending on the size of business and criticality of the mission or operation of the server. If the server operation can’t be unavailable for even short period of time, then it is better to go for hardened standalone server which is fitted with extra parts like extra power supply making it more reliable. Another option is to go for a server cluster which involves two or more servers connected to a shared storage device. If the applications that need to be run on the server are of critical behavior, a fault tolerant server can be selected. The selection of the right server results in efficient operation resulting in excellent performance. So now you can see why choosing the right server is so important to a user.

We all know about website appearing in front of our monitor while surfing the Internet but do you know that there are different systems for websites. One of the systems for websites is the Linux system. The system that we are referring to now is the OS (operating system). So, what do we know about the website system and why a Linux operating system.

For those who are actively engaged in the world of websites, they sometimes go by the name of webmasters. A Linux web hosting is a system that is appropriate for them as it be very compatible with open-source programming languages like Perl, PHP and Phython.

A server is a computer program that manages and provides services to other programs in the same or other computers. The various servers are application servers, database server, fax server, game server, communications server, file server etc. The computer in which the server program is running is also called as a server. This belongs to the hardware section of servers. A single machine by itself can act as a server or multiple machines can jointly act as a server depending on the workload and it is down to the user to determine which is the best method.

Servers act as a centralized gateway for resources and data. Moreover servers can be accessed remotely and across multiple platforms. Since multiple machines are controlled by the server, any global change can be easily made at this single location. Many servers are designed to operate over a long period of time and often unattended. Compared to the normal work station computers, servers have better hardware configurations which includes a faster CPU providing a better processing power, larger hard disk and faster RAM and uninterruptible power supply. Also software limits are often overcome in servers due to licensing.

In the computer world, servers are often used to represent the ability to handle multiple operations or requests. Since server provides services to multiple machines connected over a network, fast network connections are mandatory for efficient operations. It is not so common to see server machines with a graphical user interface. In most cases, the long running servers do not need a GUI and moreover this helps in avoiding unnecessary consumption of resources. Servers often contain multiple power supplies and hard disk as a security measure to provide backup.

Servers are normally rack-mounted and kept isolated in server rooms. The boot up time for servers is long compared to normal workstations as the special operating systems running on the server do extensive memory testing and verification. Many system checks are executed while boot up so as to reduce failure rate. Linux, FreeBSD, Solaris are some of the popular operating system for servers. Linux servers run on Linux operating system. The best example for client server model is the internet itself with millions of servers connected together and all accessing and sharing data at the same time 24 hours a day.

The size of a server varies from a Blade server with minimal physical space to a rack-mount server which can be quite large. Multiple blade servers with various functionalities are often clubbed together to provide operations similar to a multi-operational rack-mount server and many businesses have this kind of set up in a dedicated room. Intel server systems as well as software’s available in the market are designed to deliver high levels of performance. The rack mount Intel server systems are widely used for energy efficient applications. AMD servers with quad-core processors provide excellent performance-per-watt efficiencies which makes them the ideal choice for anyone who is wanting to keep running costs to a minimum whilst still taking advantage of an excellent server.

Servers differ in the services they provide to the client machines. Servers are classified based on application as wells as the physical structure and size. Application servers run certain specified software applications. It can be a software framework which hosts the services or a hardware platform on which the services are deployed. The database server provides access to the primary locations of data. The entire data is stored at a single location which then makes it easy to access them from multiple client locations that can then also run concurrently.

A communication server provides the platform for the communication network. The fax server and the file server differ in the service they provide. A common type of server is the game server which acts as a common point for online gamers. Proxy servers act as a bridge between the client machine and the server. The proxy server filters the requests from the client based on the service and server demands and connects to the required server. Proxy servers are capable of editing the client requests.

Software’s that control the access to sound devices come under sound servers. Web servers accept the client HTTP requests and provide them the HTTP responses along with some optional data. Web servers are generally rack-mount servers. A home network which contains multiple machines like fax machine, printer, media devices etc can be controlled from a single machine called the home server. Home servers run on a variety of operating systems including Windows, Linux and Solaris.

Linux servers come with fully functional media service support and hence they are widely used as home servers. A common and free Linux home server is Amahi. Blade servers and rack-mount servers differ in the physical space they occupy. Blade servers also come with a blade enclosure capable of including multiple blade servers of various functionalities. Blade servers are commonly used for web hosting and cluster computing as they are ideal for these types of uses.

Blade servers are capable of handling large workloads. Rack-mount servers are those in which servers are arranged in industrial rack. A single standard rack is capable of holding 10 to 20 servers. Rack-mount servers come with rails or slides to ease inserting and removing the components. The rack mount server which comes with locking pins helps in easy server installation and removal which helps to make it both accessible and secure.

Multiple machines in a single rack are controlled using a single keyboard or mouse through a KVM switch. AMD has launched many server systems as well as chassis for rack mount environment. The Opteron server blades from AMD offer many benefits. The rack mount communication servers from Intel are widely used for data network application because of its rugged design and long life. The Intel rack mount servers come with the latest dual core and quad core CPU technology. Intel blade servers are suitable for small-to-medium as well as large data centre customers which makes them ideal for large offices and so on.

In Web hosting there are two different worlds. One that uses Windows OS and the other that is powered by Linux systems. There are many differences between them but here are a few that are crucial for deciding which hosting type to choose.

1. Supported technologies

If you use some of the following languages or databases you need a Windows hosting:

.NET scripts

Microsoft SQL

Microsoft Access databases

ASP or ASP.NET scripts

There is a simple reason they will only work on Windows servers.

On Linux on other hand you will be able to run:

PHP scripts,

MySQL databases,

Python,

XML and many other languages yet to come.

The main reason for that is because Linux is an open source system where anyone can contribute to development.

2. Price

The fact is that Linux hosting plans are much cheaper than their Windows fellows. Why is that? The reason hides in price of the software that hosting companies have to buy. Windows server software is quite expensive while Linux is free of charge. Smaller costs for hosting company means smaller costs for you.

3. The open source

Linux is an Open Source code, which enables people from all around the world to contribute to its development. That fact has given Linux the leverage to kick out Windows out of hosting game. Because of its extreme versatility Linux has become a platform for many new technologies that became widely used in hosting industry. This means that Linux is giving you far more options as an user that Windows does.

Conclusion

Many people even don’t know what their page is hosted on. Currently (2006) Linux servers are dominating the hosting world. If you do not need support for Microsoft products or use ASP go for Linux hosting. It is cheaper, and gives you more freedom.

A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting where the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.
One of the reasons people choose to outsource dedicated servers is the availability of high powered networks from multiple providers. As dedicated server providers utilize massive amounts of bandwidth, they are able to secure lower volume based pricing to include a multi-provider blend of bandwidth. To achieve the same type of network without a multi-provider blend of bandwidth, a large investment in core routers, long term contracts, and expensive monthly bills would need to be in place. The expenses needed to develop a network without a multi-provider blend of bandwidth does not make sense economically for hosting providers.

Many dedicated server providers include a service level agreement based on network uptime. Some dedicated server hosting providers offer a 100% uptime guarantee on their network. By securing multiple vendors for connectivity and using redundant hardware, providers are able to guarantee higher uptimes; usually between 99-100% uptime if they are a higher quality provider. One aspect of higher quality providers is they are most likely to be multi-homed across multiple quality uplink providers, which in turn, provides significant redundancy in the event one goes down in addition to potentially improved routes to destinations.

Law enforcement recently has been following the general tide of government and public service groundswell by seeking computing solutions in the Linux direction. Particularly in law enforcement, their needs match well with open source software. They have to work lean on a taxpayer’s budget, and open source is free or low cost. They need top security, and Linux is still the highest-scoring operating software in official government assessments. They need mission-critical reliability, and Linux is so stable, it doesn’t just outrank the competition in stability – it makes the competition disappear!

Some recent examples of law enforcement agencies finding a solution in open source:

* Kent Police have lowered the cost of running their major criminal investigations system by a factor of 90% using Novell Linux Open Enterprise Server. The migration to Novell enabled Kent to scale up their Holmes II investigation system to work on larger projects with a broader scope – something they’d never been able to do before. They were also able to run it on their cheapest hardware they could find, thanks to Linux’s light requirements. A new policing operating system, named Genesis, is now being tested for scalability on Linux servers.

* Delivery of the first Linux systems to the West Yorkshire police force could see police forces throughout England and Wales unanimously switching to Linux desktops in a new pilot scheme. The deployment is taking place under a contract awarded by the UK Police IT Organization. If successful, it will lead to over 60,000 desktops deployed. In West Yorkshire alone, the installed base is around 3,500, and a spokesman reckoned that the savings from this would be around one million pounds per year!

* The New South Wales Police department is currently undertaking a major upgrade to its information infrastructure, made necessary due to the increasing volume of data handled by the force, and they’re switching to Linux systems to handle the load. Because the Linux systems are proving so reliable, they are looking forward to the higher capacity network more efficiently archiving and transmitting data stored as evidence, such as surveillance videos and audio material.

* Scottish police forces have also developed a Linux-based system for ensuring that they comply with the Freedom of Information Act legislation, an act which is intended to facilitate ‘open government’ by allowing the public to request access to government data. Since open source and open information go hand in hand, the system has scaled easily and saved tons of labor. The force doesn’t have to worry about proprietary media formats interfering with the public’s ability to access the data, and the efficiency of the Linux system allows a lot of manual tasks to be automated where they couldn’t before. The system is literally returning officers to the streets because it has saved everyone so much work.

* Police in the city of Munich have switched 14,000 of their department computers from Microsoft’s Windows operating system to Linux. The motivation for the decision was to make the government less dependent on one information technology supplier, and to save money while increasing capabilities. One technology analyst even compared the break-through migration to the fall of the Berlin wall, referring to the oppressive requirements of dealing with a proprietary software company’s agenda.

That government feels friendly with open source should come as no surprise. Traditionally, the Internet has been 80% Linux and Unix-based systems since its creation. The first Internet services were started and maintained by government providers, who used Unix system’s built-in multitasking features and excellent speed to create a fast, reliable network. Linux, a modern version of that Unix ideal, has already established itself as the leading system for server-room deployment, but now the effects are beginning to trickle down to the desktop user level and workstation deployments, where they are discovering that Linux systems have workspace-ready features built in which other commercial operating systems are just now beginning to discover and implement.

Furthermore, Linux systems come with the guarantee that because they are open source, no commercial company can restrict their usage in the future. A platform ported to Linux can stay on Linux, without support dying out and constant upgrades creating problems down the road.

Finally, the inherent security of the Unix computing model guarantees the effectiveness of Linux without the worries over security problems. Because there are in effect no viruses which can infect a Linux system known, and no critical security exploits found in the systems even by government security standards, departments are also considering Linux as a measure to protect our national data under concerns over national security and the terrorist threat in our modern times.

What is dedicated server hosting? Simply put, dedicated server hosting simply means taking an entire web server on rent from your hosting service provider. This is different from shared server hosting, where a number of clients are hooked to the same server and share the resources of the server jointly.

What are the advantages of dedicated server hosting?

If your e-business is showing any signs of expansion, then you should probably consider renting a dedicated server. When you rent an entire server, you have the freedom to customize the server as you wish. So, customized options are within reach. In case your website attracts huge traffic, then you will need the additional resources provided by a dedicated server. Besides, the extra money you pay ensures that you receive powerful, high-capacity servers with 24/7 on-line technical support, which is vital if you want to avoid downtime. Upgrades, when you need it, are faster and cheaper and can occur in less than 24 hours.

How to select the right dedicated server hosting?

The main reasons for you to buy dedicated server hosting are high traffic and business volumes. If you have a website that is large enough to justify the cost of a dedicated server, then the ideal host should give you access to excellent front end and back end tools. Most dedicated servers provide you with standard features like Cpanel and systems for maintaining the software you have installed on your server. Here are some points for you to consider.

Windows or Linux: Linux, if you are technically savvy and want a cheaper hosting plan. Linux servers are versatile. Windows servers are more expensive since they require bigger machines to run on and incur licensing fee. However, Windows servers are very customer friendly. Check out your comfort level and make your selection.Managed or unmanaged: Unmanaged dedicated server hosting plans come with hardware, OS and web server – and that’s all! Simply put, you only get the storage space, security and bandwidth from your host. You will have to deal with any technical issues that crop up on the way. This is enough if you are adept at handling your server yourself. But, if you are more of a businessperson than a computer geek, you may be better off with a managed hosting plan which will provide you with all the tools you need to get your server up and running properly, without any hassles.Speed: On the information highway, speed is everything. Choose a service provider who gives you top-grade bandwidth. Downtime should be nonexistent. So, look for a service provider who has the ability to re-route traffic to your website, in case your connection goes down. References: Before you drop your money into the box, ask for references from existing clients. You do not want a service provider whose quality of service is below your expectations. Find out if the provider has the know-how and the technical backup to follow through with their promises. High performance, easy management, quick maintenance and good search engine rankings are necessary for the success of your business. Look for a provider who can give you all these and more.

What Is Linux :-

Linux is an operating system that was initially created as a
hobby by a young student, Linus Torvalds, at the University of
Helsinki in Finland. Linus had an interest in Minix, a small
UNIX system, and decided to develop a system that exceeded the
Minix standards.

Linux is developed under the GNU General Public License and its
source code is freely available to everyone. Linux may be used
for a wide variety of purposes including networking, software
development, and as an end-user platform.

Linux is often considered an excellent, low-cost alternative to
other more expensive operating systems. Due to the very nature
of Linux’s functionality and availability, it has become quite
popular worldwide and a vast number of software programmers have
taken Linux’s source code and adapted it to meet their
individual needs.

At this time, there are dozens of ongoing projects for porting
Linux to various hardware configurations and purposes. Here are
10 reasons why Linux could be the best operating system for you.

A Linux Distribution has thousands of dollars worth of software
for no cost (or a couple of dollars if purchased on CD). Linux
is a complete operating system that is :-

Stable – the crash of an application is much less likely to
bring down the operating system under Linux

Reliable – Linux servers are often up for hundreds of days
compared with the regular reboots required with a Windows
system. Extremely powerful.

Comes with a complete development environment, including C,
C++, Fortran compilers, and toolkits such as Qt and scripting
languages such as Perl, Awk and sed. A C compiler for Windows
alone would set you back hundreds of dollars.

Excellent networking facilities: allowing you to share CPUs,
share modems etc; all of which are not included or available
with Windows 95 The ideal environment to run servers such as a
web server (e.g. Apache), or an FTP server.

A wide variety of commercial software is available if the free
software doesn’t satisfy your needs.

An operating system that is easily upgradeable. After any
length of time a typical installation of Windows and software
gets into a complete mess. Often the only way to clear out all
the debris is to reformat the hard disk and start again. Linux,
however, is much better for maintaining the system.

Supports multiple processors as standard.

True multi-tasking; the ability to run more than one program at
the same time.

Excellent window systems called X; the equivalent of Windows
but much more flexible.

Linux holds a major share as a server operating system and has
the largest market share for the entire Internet. It is also
increasingly popular on the desktop as well. Internet Presence
Division provides value-added service and support on all
versions of Linux.
