Load balancing dedicated server Hosting are one of the most advanced web server solutions used these days as the requirements of client’s are at inclination and in order to manage the requirements, it is important to setup a specification where every activity on the server is distributed accordingly and load has been managed. There are many of load-balancing. Hardware Setup of load-balancing is much costlier when compared to a software load-balancing setup.
Following are few of the ways of setup :
Round Robin DNS Load Balancing dedicated server :
It is basically DNS binded server that load-balances multiple dedicated web servers. This is normally known to be used for group of clusters. Some of the main advantages is that is very simple and can easily be implemented.
The only disadvantage is that the DNS server does not know if any server goes down. It knows only the difference of the IP and does not know by server port. The IP can be cached by others and request will not be forwarded to the other server.
Hardware Load-balancing dedicated server :
Hardware load-balancers route TCP/IP packet to different servers in a cluster. They are highly-reliable but with a cost. It used network gatewat to route traffic. The only disadvantage is that it is cheaper to software versions.
Software Load-balancing dedicated server :
These days, software load balancing dedicated servers are normally used which are integrated with web servers and application servers. They are much cheaper when compared to a hardware load-balancer and can easily be configured as per requirements. Unlike, Round-Robin, it can easily route based on different parameters. It requires additional hardware for complete setup of load-balancer.
Exchange Servers started in 1993 and outgrown since then. It was built in XENIX which is a version of Linux Operating System licensed by Microsoft from AT&T in the 70′s. to exchange server in April 1993.
The users were around 500 in Exchange server in Jan 1995 which then increased to 32000 in 1996. It was then migrated to beta version and the next version was brought in the market.
The Exchange Server 4.0 was released in 1996 and officially sold to public and was to upgrae Microsoft Mail 3.5. It was utilized by 400 client server mails with one database and 500 directories. Following release version was 5.0 which was released in 1997 introduces Administrator console integrated to SMTP-based networks. It also had an add-on feature known as Intenet Mail connecter which could directly communicate with server.
Exchange Server 5.5 was then released in 1997 which came in two versions, Standard and Enterprise. There were many differences in storage limit, mail transport connectors and had the ability of cluster servers.
Exchange Server 2000 edition was released in 2000 which many improvements and it’s limitations were reduced compared to Exchange Server 5.5. It supported more than one cluster and increased it’s supported database. Instant messaging support was also includes and the version includes Microsoft Acive directory which was unavailable in the previous version. The era was then supported by Exchange Server 2007 which was released in 2003. It was supported on Windows 2000 Server and Windows Server 2003. This allowed easy upgration from one operating sytem to another. This was mainly used by major organizations which could not afford downtime caused due to dedicated server migrations.
It main feature includes disaster recovery which allowed administrators to bring servers online faster by sending / receiving emails and recovering them from backups. It also provided anti-virus and anti-spam.
This was introduced in two versions such as standard and enterprise. The standard version allowed 75GB of database storage whereas Enterprise edition allowed 16TB and 4 storage group with 5 databases per group. However, it was only compatible with 32 bit version and not install on 64-bit windows server 2003.
The lastest version is Exchange Server 2007 which was in the beta version in 2006. It can run on 32-bit or 64-bit version of Windows Dedicated Servers. The performance has been improved with this version when compared to Exchange Server 2003.
Exchange server 2007 also introduces features such as voice-mail, filter options, web service support, Outlook Web Access new interface.

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/
VPS Hosting are just an next step to shared hosting packages and which are not really expensive such as a dedicated server. The features that are provided by VPS Servers are more or less like a dedicated server. no shared hosting packages provide full root access on Linux VPS’s or administrator access for Windows VPS Hosting packages. Customization are much more feasible when it comes to a VPS and it also allows third-party applications.
Much better performance when compared to any shared or reseller hosting packages. You will be able to host in a custom environment. However, in most cases good amount of knowledge is required in order to host a VPS. If you have a fully managed VPS, that would do much help and also assist you with major operations.
Also, be assured that you need more information on the VPS in order to host it. Best way is to gain as much knowledge from the host as possible. At the time of signup, please make sure you select the right options in order to meet your requirements. Wise selection of hosting package are always good for your pocket. Once you are aware of the vps you need to signup, please make sure the hosting provider can install it for you. You should not host any application or software that can likely over-load the VPS at the end of the day.
Complete isolated environment and indivualism is maintained on a vps at any point of time. Bodhost provides fully managed VPS Hosting package which are monitored 24×7 round the clock. For more information, please have a look at this link VPS Hosting
