Server Clusters

Scale Your Business Faster and Ensure Uptime with High Availability Server Cluster Hosting, Our server clusters are custom-built to fit your business needs, from two to 200 servers. Additionally, we offer managed services for mission-critical apps that you won’t find elsewhere, like managed high-availability and high-performance.

What Is Clustered Hosting/ Cloud Servers?

On traditional hosting servers, all services are hosted and run in a single physical machine, including web, database, email, FTP and others. Any service failure could affect one another, even break down the entire server operation. Clustered hosting is a type of hosting that spreads the content and load of hosting across multiple servers to do different jobs, i.e. to make your Application (and other hosted services) perform better, faster, always available while minimizing the chance of single point failure.

What Are The Benefits Of Clustered Cloud Servers?

High Availability With Server Redundancy

In regular hosting, your Application and services are hosted on one server. In the event of server failure, you will face inconvenience such as your customers not able to view your Application. And if email service is down, you will not be able to send or receive emails under the hosted domain.

In a clustered hosting environment, your Application and services are hosted on more than one server to provide redundancy. If a server within the cluster crashes, the other available servers will take up the role of the server that has crashed.

Prevent Resource Overloading With Load Balancing

Instead of hosting on a single server to process all requests, you can distribute the workload across multiple servers in a cluster to maximize throughput, minimize response time, and avoid overload.

For example, when visitors make requests to load your Application, the load balancer will distribute the processing burden evenly or in some cases unevenly (in scenarios which servers are not of equal computing power) to all the web servers. Thus no single server is handling 100% of the web traffic, which failing could end up causing server overloading.

The chances of your Application being taken down because of a malicious attack such as a DDOS attack are also reduced because there are many servers within the cluster which are able to take the strain of the attack together.

Improved Performance With “Servers Teamwork”

You get more powerful processing resources by integrating multiple processors and memory module integrated as an interlinked resource pool that is shared across your cluster. Your Application are not served by a single server, but multiple optimized servers that result in lightning-fast Application loading speed.

If many visitors are viewing your Application simultaneously, the load balancer will distribute the traffic to the available servers so that they work together to deliver the images, scripts and page content to your visitors in parallel.

Customized Hosting With Great Scalability

You have the flexibility to configure the number of web servers, mail servers, database servers, load balancers, firewall switches, devices and the structure in your cluster to best suit your requirements.

Whenever you need a higher resource for a specific service, you can easily add more servers to the cluster which spreads the work around, ensuring degradation of service will not happen. Clustered hosting is perfect for those needing greater flexibility and room to expand.

	Single Server Hosting	Clustered Servers
Server Load	A single server takes the entire burden to handle all services (web, email, database, DNS etc).	Services are specifically spread across multiple servers in a well-organized structure, making them easier to be managed, maintained and protected.
Failure Risk	Single-point failure happens when hardware failure or server crash.	No single-point failure risk.
Standby Server	No standby server to operate when a server failure happens.	Standby server always available to continue functioning when failure happens.
Web content work load	All Application contents & applications served by a single server.	Application contents & applications served by multiple servers in parallel action for faster delivery.
Requests work load	100% of requests are processed by a single server.	Requests are prioritized and distributed to multiple servers intelligently to speed up the response time.
Database Security	Databases are stored in the same web server that is more vulnerable to malicious access.	Databases are securely stored in the back-end server and well protected from direct access.
Firewall Protection	Limited firewall protection.	More firewalls can be set up within cluster layers for better security.
Email Queue	Lengthy email queuing occurs when sending a massive number of emails.	Email queue is distributed to multiple mail servers to noticeably reduce the email processing time.
DDOS vulnerability	More vulnerable to DDOS attack.	Smart load balancing to multiple servers reduces the chance of DDOS to crash your Application or applications.
Downtime	Downtime happens during hardware maintenance and repair.	The server still continues functioning during hardware maintenance and repair.
Scalability	Can only scale up (Adding more CPUs or memory to a single server)	Flexible to scale up (Add more CPUs and memory to a single server) and scale out (Add more servers to a cluster)
