What is Clustered Hosting?

[adsense_id=”1″] Clustered hosting, also known as a web farm, is a technology incorporated in order to eliminate any single point of failure by stretching requests to a given website across more than one connected server. All services are balanced across the network, spreading the website’s load just as thin. When one server is too busy to easily handle a request, it is passed instantly to the next low-load server. The platform itself is data-driven, meaning that no human interference is needed to provision a new account to the platform, and all configuration changes to the cluster are propagated immediately.

Clustered hosting allows servers to load-balance this way because all resources are ‘virtualized’ across the entire cluster of servers, giving any web site on the platform the combined power of all servers in the cluster. All applications are balanced in real time, allowing the web site to run using the combined processing power that only a cluster can provide.

When provisioning new accounts, services, or configuration changes in a cluster all servers are propagated in real time. This is unlike shared hosting, where new provisions are usually employed only once per day, and dedicated servers, where a configuration file is typically updated after rebooting. The reliability and ease-of-use offered by clustered hosting is unique to its purpose, allowing your site to run at full speed with very little worry as to downtime.

Clustered hosting architecture has multiple tiers of security between the operating system and its running applications, making the system almost invulnerable to infiltration. This means that, besides having the power and sustainability of multiple servers, web sites in a cluster also have impeccable security and stability. Typical hosting architecture does not have a security layer built into its platform, leaving a software firewall as the last line of defense for a web site. Once the firewall is bypassed under these conditions, the operating system and its exploitable areas are left wide open. Clustered hosting eliminates this potential security breach by stopping attacks before they are ever able to reach the operating system.

The use of redundant switching, intelligent routing, and a cluster’s built-in firewall and proxy make it an ideal battleground for denial-of-service and other network-based attacks, adding yet another layer of security for your web site. These attacks can be easily spread across the server pool, and all affected hardware is immediately excluded from traffic handling, leaving the rest of the cluster to simply continue running at its normal pace.

Why is Clustered Hosting Right For You?

Clustered hosting can provide you with a stress-free base to control and grow your site and business. The dynamic scalability allows you to incrementally scale-out your business applications as the need arises; the hardware is always there when you need it. The combination of the parallel architecture and built-in security features makes for a secure clustered system with no single point of failure, helping you to make sure that your web site is always online and easily accessed by your users.
