All about Web hosting and Dedicated server hosting
What is a shared hosting, Why use a shared hosting?
Virtual machine technology, can host a truly divided into many "virtual" host,
each shared hosting has a separate domain names and IP addresses, with a complete Internet
server (www, FTP, email) function. Web hosting is entirely independent, outside, each
shared hosting and a host exactly the same independent. The same effect, but the cost is
quite different. Because multiple shared hostings share a real host of resources, each
shared hosting user to bear the cost of hardware, network maintenance costs, communication
costs are greatly reduced lines, Internet truly affordable for everyone in the network!
Currently, many companies set up Web sites using this method, it saves not only the
purchase of machinery and leased-line costs as well as the use and maintenance of servers
without the technical aspects of fear, not to employ specialist managers, because these
things to us to restaurants.
A machine's resources to be allocated to multiple shared hosting, each shared hosting will
decrease the performance of
This issue depends on the performance of the host and the creation of the number of shared
hostings, if configured properly, with high bandwidth circuits, shared hosting will be
faster than a lower-bandwidth connections independent host. Number of users per host will
be controlled within a certain amount, in full performance while using the system to
protect the interests of customers.
What is the server hosting
When the user intends to have their own Web, Email, FTP and other servers, he can have two
ways: first, self second is managed.
Self requires a high level of professional and technical personnel, to put greater
resources for the purchase of hardware and software, but also pay for routine maintenance
is not capping and line communications, and longer construction period. In comparison,
managed the economic, efficient and useful.
The basic action mechanism of Internet users / server (Client / Server), the biggest
feature is the inter-temporal and cross-boundary. In other words, even apart, as long as
everyone on the network, the two sides can communicate directly, which provides us with an
important technical means: Remote Control (RemoteControl). Server Hosting created the
technical basis and depend mainly means \ "user / service \" and \ "Remote
Control \" and other mechanisms. That no matter where our users, as long as the
Internet, you can feel so far to control the server, the server has to achieve and
maintain.
Server hosting and shared hostinging What is the difference
Server hosting business can be broken down into server hosting and shared hostinging
(shared hostinging). "Server hosting" is a real connected with Internet network
environment when the company put a server, or to rent a server, customers can remotely
control the server configuration as WWW, E-mail, Ftp server. "shared hostinging"
means: to a UNIX or NT system, designated small machine's hard disk, after the breakdown
of hard disk space for each block can be configured as an independent domain name and IP
address of the www, email, FTP servers, such server, by people browsing, can not tell it
to share with others, a host system resources. In this machine you can rent space by
remote control technology, such as file transfer (FTP), full control is part of his space,
such as downloading information, applications configuration and so on. It should be said,
by "shared hostinging" this approach has a separate site, the cost performance
is much higher than their own construction and maintenance of a server, the current way of
establishing the site was being more and more enterprises and institutions used.
Assessing the server where the performance of several
A. server hardware configuration
B. server software configuration
C. The operating system installed on the server and development environment
D. server support functions
E. server network environment where
Server is to access what factors determine the speed of the
A. server's hardware configuration (including the type of server, CPU, hard disk speed,
memory size, card speed, etc.)
B. server environment where the net rate of
C. server network environment where the Internet backbone network associated with the rate
of
D. ChinaNet international export rate
E. visitor's ISP (Internet access service provider) and the line between the rate of
ChinaNet
F. visitor's ISP (Internet access service provider) to the client open the port access
rate
G. visitor computer's configuration, Modem rate, quality of telephone lines
Why should provide Web + EMail + FTP server hosting
"Web, E-mail, FTP" function is more basic three commonly used Internet
functions. Web function, is enabling visitors to type the domain name through a browser,
visit the home page of the site owners, to promote corporate image, product purpose. Email
function, by setting the company's own domain name with Email box, can establish the
image, but also set up a convenient, low modern communication links. FTP functions can be
realized so that interested visitors to download the file, increase the rate of site
visits. The three functions from the user, whether corporate image, product promotion, or
from the after-sales service, online technical support, are essential.
Can multiple domain names point to the same site
On the server settings, we can achieve multiple domain names point to the same web site,
users can access with multiple domain names on the same site with a page contents.
How to test the speed of the shared hosting
Modem or green if you are directly associated through the network, or through a Telnet
gateway functionality, you can network you want to know \ "ping \" look. PING
command to your current host to the target host sends a \ "package \", target
host receives the \ "packet \" will be immediately and automatically return to a
data packet, and then, you get a A round-trip packet time spent.
Such as \ "ping www.microsoft.com \", then Enter, you will get from China to
visit Microsoft's server response time. General, \ "PING \" command will
automatically continue until you terminate it, such as knock \ "ctrl + C \".
If you are familiar with the features Telnet, PING, and you has the network of the Telnet
different account, you can different network-based and the other of Zhujijinxing PING
²âÊÔ, you can compare the different access points Zhexie Pi access the host's response
time and get the \ "packet loss rate \", the average response time test results.
However, PING command can only be tested over the underlying network and server
performance, may reflect the Unicom network bandwidth and data congestion level, but a
higher level of server performance are not well reflected - which, most important, such as
running host on the Internet Web server software and hardware efficiency (the efficiency
of the decision through the Web server files directly download speed - that is, users
access the server's speed), you can not give. In fact, there are some well-known
international neutral body, to help users understand server performance and other
information server, opened a number of specialized test stations, available to the users
of these tests. Among these, Monte Sano Software company run NetMechanic sites give users
the main server performance testing services free of charge.
The Website address is:
http://www.netmechanic.com/server_check.htm
Access http://www.netmechanic.com/server_check.htm, you can type directly in the interface
need to test the server's domain name address, and enter your EMAIL address so that the
testing service to every 15 minutes on the target site send a test, 8 hours after the test
results will be posted to your E-mail mailbox. The service can be a major operation on the
server performance, such as PING response time, DNS resolution time, CONNECT time, Web
server file download speed for each test point given the data and average.
Now you can by using these methods on your own websites or other websites of interest to
test, while Microsoft can microsoft.com, Netscape netscape.com, yahoo.com and other tests,
were compared.
As the service site in the United States (in ServerPro service also provides access to
tests of European origin), the test results to the United States access to the source.
Therefore, we will find the site to host the test results in the United States shows a
very high speed of the network, it shows one in the U.S. (or Europe) of the user access to
host access to our results. Sites on other national tests, is relatively much lower rate -
that is what we often hear of China's international export network data line bottlenecks.
PS mentioned in this Netmechanic server performance test site free of charge because of
the recent testing requirements are sometimes too much, you may experience \ "Sorry,
full testing requirements, please submit their applications over a period of time \"
situation. Just try again some time, all will be able to join the ranks of free test, and
one can also enter more than one test.
What is NT Load Balancing Service
WLBS (Windows NT Load Balancing Service) is a network service, used to manage different
servers between the TCP / IP communications. WLBS not a beautiful pseudo-application
distributor, to share the server CPU load, it is more suitable to be described as a
network traffic based on a more flexible dynamic load balancing service. The most commonly
used load sharing technology is Round Robin DNS (RRDNS). In RRDNS technology, the request
was just a simple loop to send to different servers. So when one of these server crashes,
the request will still be sent to the machine. The WLBS host server is working and
determine whether to accept the request, in order to overcome this weakness, if the above
situation, WLBS put network traffic sent to another server, thereby avoiding mistakes.
When the application and the Web site to meet growing traffic demand, you may even want to
CPU unloaded from one server to another stage to go. Not long ago, you can only select
Round Robin DNS and expensive hardware to share the system load. But now, WLBS for
Microsoft Enterprise Edition Server 4.0 can help you spread the server TCP / IP traffic.
The distribution of services so that you can add Web servers to meet growing load site
To improve performance, WLBS services provide real-time fault tolerance to increase in
maintenance and unload the server. If you plan to undertake mission-critical Web
applications to increase more features and better reliability, then the above mentioned
combination of these features, they constitute an essential service.
