Replication

Definition

Data replication is the process of copying data for redundancy as it is written. For disaster recovery, data is replicated to a remote site to provide another copy outside of the data center.

There are two types of replication - synchronous and asynchronous.

While synchronous replication continuously updates the replicated data and waits until the write has been copied to the target site before acknowledging the write to the application, asynchronous replication tells the application that the data has been stored while it is copying it to another site.

User Benefits

One of the user benefits is that they will be able to have access to the latest data in case of a main site is not available due to the fact that every transaction is replicated to the secondary site. The same situation happen when the replication is done in the same location where the production units are installed, fail of the production systems will not affect the users.

The process is transparent to the end-users so they will not be aware from where they access the data or applications.

Business Impact

One of the main concerns of every business is to assure availability and accessibility of data. Availability and accessibility means immediate access to the data which translates in a competitive advantage.

If you analyze replication from the disaster recovery point of view, a company that implemented such technology will be able to regain the activity with the latest data, while competition that didn’t implement such technology that still struggles to regain from the disaster.

This can earn the trust of your customers and business partners because they can see that they are working with a reliable partner.

On the opposite, losing company assets can be fatal for the business.
