Clustering solutions with dedicated managed servers

Clustering is when a group of two or more nodes (computers) work together as one single system to provide a high availability of services for users.

When a failure occurs on one server in a cluster, resources are redirected and the workload is redistributed to another server in the cluster, meaning no single point of failure.

The failover time is greatly reduced and there is less chance that data will be lost during a system failure. Data does not have to be sent to a backup system at time of failure, because it is already on both servers.

The cost factor is reduced since it is not necessary to have a separate RAID (Redundant Array of Independent Disks) in each server.

There are a few types of clustering solutions and we offer SQL and MySQL.

Benefits of clustering solutions

• There is zero downtime with 100% availability.
• Replication can take place using standard network protocols, over any distance to any location.
• Minimum bandwidth is used.
• There is queued task processing to automatically trigger tasks.

Database replication in clustering solutions

Database replication involves a small software module being installed on each source and target server. An easy-to-use client application lets the client define which data will be replicated and where the copies will be stored.

The initial mirroring operation can be performed while the source servers are active. After this simple configuration and initial mirroring are completed, operations are automatic and transparent.

The failover module resides on the target (passive) server, and continually monitors the source servers. In the event of a server failure the target server can assume the names and IP addresses of the failed servers (in addition to its original name), and invoke scripts to restart applications.
