Cluster hosting is regarded as worthy by many website owner because they have such features which is not available in any other hosting service provider. If you go through the features then you would understand why it is worthy to invest in a clustering hosting service.
Always available: Any clustering hosting service provider is created with such architecture that your web applications will be available always. It also comes with automatic server recovery facility so that an application can move to another server if one or more servers fail to operate. If all the servers fail then the entire set of data can be recovered safely through the use of log execution and checkpoints.
Excellent performance: In cluster hosting the response time and throughput together work in tandem to meet the demand of critical and heavy applications. All data is kept safely in memory and bottlenecks do not happen always because of the writing of transaction logs to disk.
Automatic failover system: With this service you would get quick failover time within few seconds so that all the data in your applications can be recovered when there is a server failure. Also the servers can automatically start, recover and also reconfigure themselves and therefore no advanced features are needed to be added into any application.
Low maintenance cost: Since this type of service is designed in a self-governing fashion therefore there is not much need of fine tuning the systems and thus there is no need of extra cost. You would find that there are very less conflicts between hardware and software and thus needing no or little intervention.
Scalability: This type of hosting service is configured in such a fashion that you can implement the level of performance, the system of fault tolerance and level of scalability in the way it matches the requirements of your applications.
User friendly: The tools used in cluster hosting can be used easily and they are extremely powerful. Thus you can easily monitor the nodes of database, control the access to the applications and can easily create the backup files as well as restore the backup with the help of the command line tools.
