Server Uptime has the maximum importance in the Internet world. Getting a Dedicated Server mirrored can help you stay online at any given point of time. Dedicated Server Mirroring is a concept that has been preferred by large business to carry out the mission critical tasks.
“Server Mirroring” the name itself gives an idea of the technology. In this the data is mirrored or duplicated on two servers that share the same configuration. In this type of hosting service you can opt. between, Mirrored Dedicated Linux Servers and Mirrored Dedicated Windows Servers. This technique is a type of file or data synchronization and is widely preferred due to its reliability. In the Mirroring architecture, two systems are linked together. When there is a data transfer, the data is transmitted to either of the servers, but, the same data is duplicated on the other server/s as well. Encryption is possible too on the mirrored servers. This technology can be applied to WAN as well as LAN architecture of servers.
In this type of architecture, the web hosting provider, sets up the servers of similar configurations on different locations ie. different racks, different geographical locations, different datacenters etc. Usually, it is suggested to keep the servers in the same datacenter to avoid a delay in the delay in mirroring of the data. One among the servers is a Master and other as Slave or Secondary Server. If due to any reason, the Master Server fails to respond/ work, the Secondary Server takes over and starts operating as a Master Server, this avoids the possibilities of the downtime of website/s. FAM and RSync modules are used in the Mirroring architecture. When the Secondary server works as Master server, the process is called as a Failover Process.
Once the Master Server is replaced or repaired and re-installed to the network, the Restoration process gets initiated. In this the latest changes on the Secondary server that has taken place when the Master Server had failed, is now restored. Now, when the Master servers functionality has been resolved, the website data again starts getting resolved from the Master Server.
This kind of architecture proves to be an effective way of avoiding the downtime of websites. The Mirroring architecture helps in preventing the loss of data. You can avail this service from Web Hosting providers on request.
