What Is Active Active Replication
What Is Active Active Replication. Active replication was first introduced by leslie lamport under the name state machine replication. Active directory has two basic types of writes to the ad database, a replicated write (where the change is performed on another dc) and an originating write (where the change is performed on the local dc).

The replicas receive updates from the master, sharing the same mvcc timestamps. All replicas respond to the client’s request. Connections are configured between sites to ensure that active directory objects are replicated between sites.

This requires that the process hosted by the servers is deterministic. In this configuration, a mirror module replicates a full virtual machine and restarts the virtual machine in case of failure.

Figure 1 — an hpe shadowbase active/active architecture as shown in figure 1, an a/a system is a network of independent processing nodes, each having access to a common replicated database, so that all nodes can participate in a common application. What is active directory replication?

What makes this architecture active / active, is the fact that you now have consumers reading from both. Replication active directory uses multiple domain controllers for many reasons including load balancing and fault tolerance.

The readable secondary database may be in the same azure region as the primary, or,. Active/active (read enabled) is integrated into the sap hana system replication solution and gets activated with the operation mode logreplay_readaccess.this operation mode provides fast takeovers, reduced need for bandwidth in continuous operation, and support for replication modes such as sync (with or without the full sync option), syncmem, and async.

It is to be made sure that every replica receives the client request in the same order else the system will get inconsistent. Replication within each cluster is synchronous but between clusters it is asynchronous which means the following scenario is possible:

Shadowbase replication keeps the data in the separate databases synchronized, and ensures that the records are. The dr site only starts processing requests (becomes active), if the primary data center fails.

Deterministic means that, given the same initial state and a request sequence, all processes will produce the same response sequence and end up in the same final state. Active replication was first introduced by leslie lamport under the name state machine replication.
