    • There is no distance constraint between data centers, data centers can be located in different cities, nations, continents.
    • Maintenance on single data center at a time takes place without interruption, through ACTIVE-ACTIVE architecture.
    • Does not require any intervention to existing software on data centers or to software that will be acquired later.
    • Data in both data centers is equal instantly. The data written to one data center is instantly written to the other data center. Thus, there is no data loss, data integrity is not deteriorated.
    • Both data centers respond to read and write requests with load balancing, resources used effectively.
    • Capacities such as 1 Gbit / 10Gbit is not required between data centers.
