Dedicated servers are those that exclusively serve a single client. A web master should think about the possibilities of unusual traffic surges towards the site and prepare to maintain enough data transfer, speed and accessibility.
Dedicated servers make available the entire disk space and processing speed for a single domain. This greatly enhances website performance and ensures better data transfer. Dedicated hosting may be managed or unmanaged by the host. In case of managed hosting apart from physical server, the host also provides other services like system administration functions, upgradation and maintenance and also installs certain software. Managed systems are better, since the host offers immediate service, in case the server crashes.
While moving on to dedicated servers, the client must make sure of the increase in web site usage and corresponding earnings. The costs involved and the facilities that such servers provide would not be utilized to the full extent for a fairly new site with poor sales.
The past performance of the host helps to decide the reliability for the client. The agreement should specify the level of security, both virtual and physical that is expected to prevent data theft, and sabotage. A proper comparison between various hosts should be made regarding the amount of memory, size of the hard drive, speed and type of processor, and the bandwidth provided. These may be customized to requirement and frequently upgraded.
A website that is smaller in size with an average level of traffic expected can make do with a shared server. A shared server is much cheaper compared to a dedicated one, but offers a restricted amount of free disk space, bandwidth and data transfer and speed. A shared server hosts a number of other websites that may be related with totally different businesses. Although, the client will be offered a fixed level of disk space and bandwidth, the excess traffic towards other sites on the server may affect the accessibility of the site.
Most available shared servers have a huge variety of packages on offer. The advantage is that web master pays only for the amount of service and space they use. Shared hosting charges vary from dollars 3 to15 depending on the number of services availed and the location of the host. The cheapest offers are best for those with websites that are not attracting heavy traffic.
Virtual private server (VPS) can also be used as a method to host websites, instead of installing a separate computer for the purpose. In this, a physical server is partitoned into multiple servers that have unique appearance and capacities, as separate entities. Each has its own operating system and can be independently rebooted.
VPS is useful for websites that manage a lot of interactive media. It s also suited for those needing to set up parallel websites. The costs involved are on the higher side and hence is advisable for sites that see an upward trend in revenues. The advantages include the option of root access, that lets the web master to choose the software required for client management.
A decision to shift over to a better software to manage an already huge customer database is easily done through this option.
