Clustered Hosting: Optimized Resources Usage for Better Performance
In most of the web hosting environments, the website and all its associated data are located on a single server. So if the datacenter faces hosting problems like server goes offline, this would cause serious trouble. The solution to this problem is Clustered Hosting.
Generally, most of the hosting solutions use a single server for hosting multiple hosting services like website, database, FTP, email etc. So, it has a single failure point and finite traffic capacity causing troubles for high traffic websites.
Clustered Hosting differs from the traditional web hosting mechanisms as the load of web hosting is spread across “nodes” which are multiple physical machines, thus increasing the availability and also the chances of one feature or service like email or FTP, affecting other services like MySQL. Large websites, discussion forums use clustered hosting as they run with multiple front-end web servers and back-end database servers.
Single failure points can be eliminated by load balancing in clustered hosting using multiple physical servers. In a single server, periodic reboots maybe required for software upgrade but in clustered hosting the reboots can be staggered to make the services available while upgrading all the necessary machines present in the cluster.
The advantages of Clustered Hosting are:
- Enhanced Reliability: The computer grid is powered by several clusters running dedicated hosting services with more than 2 servers in each cluster. All the clusters work together for hosting the website and eliminate single point of failure.
- Flexibility: Many servers can be added to a cluster and many clusters can be added to the grid for increasing availability as and when required.
- Maintenance: Scheduled or unscheduled maintenances of the servers for hardware check or software upgrade, don’t affect the website.
- Enhanced Security: Security can be enforced at all the layers for maximum protection from Kernel to the applications. Classes of attacks like SQL injection, cross site scripting, buffer overflows etc can be stopped.
- Load Balancing: The workload is distributed across multiple nodes for achieving optimum utilization of resources. The load balancers use schedule mechanism for prioritizing requests and forward requests for processing to the servers.
- Better Performance: Close integration with load balancers allows the web servers to perform parallel request delivery. So, the web pages are served very fast.
- Fast Raid Storage: In clustered hosting, the storage of data is redundant, optimized and protected from single point failures.
- Faster SQL Queries: For faster execution of database queries, multiple instances of SQL database services are run concurrently. Unattended queries are promptly handed over to another available database server.
- Reduced Mail Queuing: Implementation of a more balanced system of distribution of the mail queue provides better mail processing & delivery services. Multiple mail servers are used for shortening the queue.
- Fail-Safe DNS: The zones are centralized from hosting servers by DNS servers present in the cluster using a fail-redundant DNS structure
Clustered hosting costs same as shared hosting, so it is cost-effective. Access to large number of servers in clusters provides you with computing power as much you require. So, clustered hosting has gained popularity due to its several advantages over shared hosting.
