Load balancing dedicated servers offer many features when compared to a dedicated server. Some of them are as follows :
- Asymmetric load : load can be shared with the back-end dedicated server servers. This way, it improves performance on the front-end servers.
- Immediate Activation : In case of failure, the back-end server can immediately brought online.
- SSL Load Management : SSL connections can be managed through load balancing hardware.
- Protection against DDoS : SYN cookies and delayed binds. They can work offline and protects from DDoS counter attacks.
- Compression of HTTP : gzip on web browser to reduce load on the data transfer.
- TCP Offloading / buffer : Every HTTP request has different TCP Connection. It can serve every client that reaches the sever and takes care of every task.
- Caching of HTTP : It can store the data that are static, it reduces the load on the dedicated web server and does not need to retrieve the data everytime.
- Filtering : Traffic management and filtering.
- Security on HTTP : It can hide HTTP error page, remove HTTP response and cookie encryptions in order to maintain high security on servers.
- Priority Que : Differentiating between decent traffic and bad traffic.
- Request Switch : Requests can be sent to different load balancing servers as per URL that is requested.
- Authentication from client : Authentication for clients to access the website.
- Firewall : Un-secured connection to the load balancing servers are prevented and not allowed. This ensures security on the dedicated server.
Load-balancing dedicated servers with affordable prices are the best solutions to remain online always!
High-availability, redundancy, performance have become an important factor of web server hosting. Access to Internal as well as external client IP to keep 100% uptime. Any downtime occurred can bring-in loss to the company. It is also known that load-balancing dedicated server hosting configuration are highly priced. BODHost provide cheap and Affordable load balancing dedicated server configurations that suit every pocket. Even small Intel P4 configurations can be setup as load-balancers reducing a good amount of cost. However, the main concept remains that every requirement is different from one another.
BODHost understands every requirements of a client and provides them with reliable load balancing dedicated server solutions. load balancing servers improves performance on a dedicated server by managing and distributing load among servers. for example, application server and database server. It means application will run from the application server and the database will be retreived from the database server. This reduces the load on one server and distributes it between two dedicated server configurations.
Bandwidth and traffic management on load balancers are also taken care of. Fail-over dedicated server hosting setup and management are all part of BODHost dedicated server management technique program. We also run dedicated server monitoring technqiues that runs through the servers to check if the servers are functioning appropriately.
At BODHost, we understand that how important your business is and make sure everything is running smooth.

There are many more features of a dedicated server hosting package which can be included to the list.
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.
BODHost.com supports Exchange Dedicated Server Setup
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.
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.
Are you looking forward to buy a Dedicated Server ?
If are you looking to purchase a Dedicated Server, there are a few important points that we need to take care of. Basically, we need to understand our requirements such as how much disk space / storage do we require ? or how much bandwidth do you require ?
Once we have understood the requirements, we need to understand what applications are required on the dedicated server. Budget would be the next question which ofcourse is main for many client who need a dedicated server. The next would be which is the hosting company we should opt for ?
In order to research for a good dedicated server hosting provider, you need to refer a lot of reviews, uptime stats, Support test checks and others. These are few of the important points when we look forward to buy a dedicated server.
