High Availability Solution

In order to provide business continuity for your managed server, ForLinux have developed several disaster recovery solutions and will work with you to provide the best solution, backed by ForLinux expertise.

High availability server

Multi Data Centre Failover

From time to time Data Centres experience problems that can cause website downtime. A multi Data Centre failover solution will resolve this problem. Very simply, each website name has a unique IP address. This IP address points to your live server. If the server becomes unavailable, ForLinux failover software changes the IP address to a new IP address containing an up-to-date copy of your website. This process takes approximately five minutes to achieve.

This solution is best suited for websites and applications that do not have large databases but require 24 x 7 access to their sites.

This solution provides :

  • An active disaster recovery solution
  • Improved web site availability
  • Resilient, secure and highly available operations platform delivering IT certainty

MySQL Replication and Clustering

Replication enables data from one MySQL database server (called the master) to be replicated to one or more MySQL database servers (slaves). Your replication slaves do not need to be connected permanently to receive updates from the master, which means that updates can occur over long distance connections.  Depending on the configuration, you can replicate all databases, selected databases and even selected tables within a database.

This solution provides :

  • Scale-out solutions – spreading the load among multiple slaves to improve performance.
  • Data security – because data is replicated to the slave, and the slave can pause the replication process, it is possible to run backup services on the slave without corrupting the corresponding master data.
  • Analytics – live data can be created on the master, while the analysis of the information can take place on the slave without affecting the performance of the master.

ForLinux technicians have extensive knowledge and experience in implementing and supporting MySQL replication and clustering solutions.


Server Mirroring with Block Level Replication and High Availability

Block level replication refers to the process which allows data to be replicated between two or more servers in real time across a dedicated network connection, regardless of the application running on the server. The servers can be implemented in a high availability configuration, so that in the event of a server failure a standby can take over.

This solution is ideal for mission critical environments requiring immunity from server failure, for example high demand production environments.

This solution provides :

  • Data Security - data is replicated at block level between two or more servers, regardless of the application
  • Disaster Recovery - with high availability, a server failure does not impact your business processes
  • Automatic recovery after node, network, or disk failures

Included with all Complex multi server solutions:

  • Full server and application support
  • 100% Network uptime
  • 100Mbps Bandwidth
  • Multiple IP addresses
  • Patching & Security updates
  • Full Root access
  • Server performance report
