Sub-domain management is very much similar to main domain name configuration. The main difference is that it is attached to the main domain name. Request for subdomain is routed to DNS server which has DNS information for the main domain. Sub-domain DNS records resolved to a IP address, the rquest is sent to the web server that is assigned with the IP address. the request can now be moved to the website. By many DNS server entries, subdomain configuration can be taken care of and application setup for management of load or applications.
DNS server should have pointer to the sub domain as CNAME or hostname or MX entry for emails. If the IP address of the main domain name and sub-domain name are the same, we then use CNAME or alias. A records are used if the IP points to the different dedicated server in case of load balancing server setup.
CNAME is used when the IP address of the sub-domain and the main domain are the same. It means the parent domain and child-domain points to the same IP address such as :
www IN CNAME domain.com.
subdomain1 IN CNAME domain.com.
subdomain2 IN CNAME domain.com.
A record is setup when the main domain is different from the sub-domain. This is in case of a load balancing or server cluster setup such as :
subdomain1 IN A 123.2.33.45.
subdomain2 IN A 123.2.33.46.
MX records are mail exchanger sub-domains in case of email setup that will be pointing to the dedicated web server IP address and used for different email account such as :
subdomain1 IN MX 10 subdomain1.domain.com.
subdomain2 IN MX 10 subdomain2.domain.com.
If the sub-domain is configured on a different DNS name server, nameserver records is created for the sub-domain. Different nameservers can reduce security issues.
DNS Server sends the request for the sub-domain to the IP address, it starts functioning. It then needs to be configured to manage the request based on the IP address / Host headers. It is utilized by web servers to host different domains / sub-domain on one IP address.
In a Windows dedicated server, we have to use IIS manager to add sub-domains that will be assigned to IP address. Port is then set to 80. Host header can be added by clicking on advanced tab nect to IP address configuration for website application. Sub-domain that points to sub-directory of website which is then home directory for the sub-domain.
In a Linux dedicated server, we use Apache web server which is configured by virtual host entry in httpf.conf :
Listen 80
NameVirtualHost *
ServerName www.domain.com
DocumentRoot /home/httpd/htdocs/
ServerName subdomain.domain.com
DocumentRoot /home/httpd/htdocs/subdomain/
At the time of request to the DNS Server in order to resolve domain names, it provides different cnames in one order. It redirects the request to servers which are in groups. The BIND feature of DNS resolveing the domain to the server, the request are sent to the same server.
In case of Multiple CNames, when there are four dedicated web servers clusters configured with a IP address, adding them to the DNS with A names. The srv can be set as per our selectionand should meet up the next option.
srv1 IN A xx.xx.xx.1
srv2 IN A xx.xx.xx.2
srv3 IN A xx.xx.xx.3
srv4 IN A xx.xx.xx.4
Add cnames to resolve www.domain.com to one of servers such as
IN CNAME srv2.domain.com.
IN CNAME srv3.domain.com.
IN CNAME srv4.domain.com.
DNS Dedicated Server will then resolve to www.domain.com. The request is sent over group of servers.
Also, the request that is sent to the domain without www should be forwarded to www.domain.com. In order to avoid cname error, we need to do the following :
options {
multiple-cnames yes;
};
In case of Multiple A records for one domain is thus not appropriate DNS server for BIND 9. We use the following :
www.domain.com. 60 IN A xx.xx.xx.1
www.domain.com. 60 IN A xx.xx.xx.2
www.domain.com. 60 IN A xx.xx.xx.3
www.domain.com. 60 IN A xx.xx.xx.4
In this case, if any DNS load balancing dedicated dedicated server, it will have no idea if the server is down. It does not check the port of the dedicated server. IP can be cached by nameserver, the request cannot be sent to load balancing DNS server.
Round Robin DNS load balancing does have many drawbacks but can removed by using Perl scripts.
Reviewing on a Dedicated Server Hosting Package is not an easy process. Different Configurations differ in performance and should be selected as per requirement. If in case, you need to host heavy MySQL or MS SQL Database on the Dedicated Server, you need to make sure that you opt for a high-end dedicated server configuration and if you need to host a few simple HTML Websites with no restrictions, then a basic dedicated server should do fine. Reviewing each processor’s performance is important at the same time.
Every Client should also do research on the dedicated server hosting provider prior to his or her signup with them. There are many factors that we need to consider while reviewing a dedicated server hosting package. There are many server hosting companies who provide fully managed dedicated servers to their clients. Basically, what we need to find out is that if a dedicated server hosting is worth the service that we are looking for. It is most important that we take care of our requirements and meet up the specifications that we opt for.
Linux Plesk Dedicated Servers and Windows Web Servers both support Plesk as control panel. Plesk is very easy to manage on a dedicated server. Features such as Domain Management, Email, MySQL and MS SQL Database Management and much more. Website uploads with a few clicks, domain bakcups, FTP, Crontabs, SpamAssassin Setup, Plesk Reseler Dedicated Features and many more all are important features of a Plesk Dedicated Server.
BODHost Recommends Plesk as Control Panel while opting for a Windows Dedicated Server Plesk can easily integrate with databases and if we opt for Plesk add-on’s such as Plesk Power Pack, it helps us to integrate SQL Database with Plesk Control Panel and Dr. Web Anti-virus sacns for viruses on the VPS.
Debian Dedicated Servers are yet another Operating System Distribution for Linux. Many users prefer using DebianOS on their dedicated Web Servers. There are few of the basic installation procedures that we need to follow :
- Language Selection as per preferance.
- Confirmation of keyboard setup
- Installation files directly load from CD or source.
- Manual Network Setup
- Clock / Time Zone Setup
- Disk Partitions
- NTFS partition should be kept intact
- Boot Load Installation
Debian Dedicated Servers are compatible with cPanel, yet the stability has not yet out-performed.
Dedicated Servers are mostly leased and not purchased from any Web Server Hosting Provider. In order words, it may also be called as Renting a Dedicated Server. This way a client saves on purchasing hardware everytime and anytime he needs to change the servers, he can proceed with the cancelation and opt for a new dedicated server. This is a much easier process than a co-location dedicated server where a client has to purchase a dedicated server and maintain it.
The maintenance of a co-location dedicated server include is bandwidth allocations, power supply, switches, racks and software applications that run on the hardware. It is indeed a costly affair. Hence, most suggestions incline towards dedicated server rentals from a well-known dedicated server hosting provider or Data Center.
cPanel Dedicated Server
Linux Dedicated Servers installed with cPanel ( WHM ) is known as cPanel Dedicated Server. cPanel is installed on a Linux Operating System and Windows OS does not support cPanel as of now. Even though it is in beta version and preferably it will support Windows by end of this year. cPanel is known to easily integrate with the server and provide easy-to-use graphical interface to the client. The Complete server can now be accessed through WHM and you no longer need to follow the command lines. Ofcourse, you need to hit those keys for the initial installations. But that can be avoided if the hosting company provides a fully managed dedicated server.
Once installed, you can directly manage the services, DNS, emails etc. with a few instant clicks. You can also create SSH key to the server for secured access. Regular updates with better features have always followed cPanel configurations. We strongly recommend cPanel as a control panel if you are looking for a linux dedicated server.
Discount can be offered on a Dedicated Server and the percentages differ from one hosting company to another. Generally, dedicated server hosting companies offer discount on yearly prices or to dedicated server resellers.
BODHost.com offers two months free of dedicated server hosting service with our yearly prices. We also provide dedicated reseller service with increasing number of discounts on every dedicated server leased from us.
Dedicated Server Bandwith refers to the data transfer rate from one to another in a given time period and is often represented in bits p/sec
For example, visitors to your server, web site, or applications use Dedicated Server as the traffic moves from your server to the Internet and vice versa. Connectivity refers to the “access providers” that supply bandwidth, or data transfer rate, through various connection points across a network or footprint to one or multiple data centers where dedicated servers are housed.
Dedicated Server bandwidth are measured as follows following:
• Average bits and Transfer Speed
• Unmetered Dedicated Server
• Total Byte Transfered
95th Method: Line Speed – average utilization, refers to the speed in which data flows from the server or device. Measured utilizes bits p/sec , kilobits p/sec, megabits p/sec and gigabits p/sec
Unmetered Dedicated Servers : Unmetered Dedicated Server is the total Mbit/s Speed allocated to the server and configured with Port switches. Unmetered Dedicated Server services usually have an additional charge.
Dedicated server providers utilize huge number of bandwidth, lesser price from more no. of providers. This is in place of expensive infrastructure.
Network Uptime are packaged along with Service level Agreement provided by the dedicated server hosting provider. Most offer 100% Network Uptime with redundant hardware.
Basic Dedicated Servers come with 2000GB or 2TB High-Quality Bandwidth Per Month. These can definitely be upgraded to a Unmetered Dedicated Server
Unmetered Dedicated Servers
Bandwidth is one of the main features of a dedicated server. This mainly refers to ( Incoming / Outgoing ) Data transfer of the server. Basically, formula of bandwidth is calculated on monthly basis or 30 days. Bandwidth basically is in referance to packets.
Unmetered Dedicated Servers does not refer to unlimited capacity, however it is a rough figure of the projected bandwidth per month. This can be offered in many connection types such as 10Mbps / 1000Mpbs / 1Gbps.
At BODHost, we offer many different types of Unmetered Bandwidth Options :
- 10Mbps High-Quality Unmetered Bandwidth Per Month
- 20Mbps High-Quality Unmetered Bandwidth Per Month
- 50Mbps High-Quality Unmerered Bandwidth Per Month
- 100Mbps High-Quality Unmetered Bandwidth Per Month
- 1Gbps High-Quality Unmetered Bandwidth Per Month
