The key difference between these two architectures is performance. Active-active clusters give you access to the resources of all your servers during normal operation. In an active-passive cluster, the backup server only sees action during failover.

What is Active Active SQL cluster?

In SQL Server, Active/Active clustering simply. means having two separate instances running in the cluster—one (or more) per machine. So, Active/Active clustering refers to a two-node cluster, with each node running SQL Server instances but each with a different set of databases.

What is Active Active network?

An active/active system is a network of independent processing nodes, each having access to a common replicated database such that all nodes can participate in a common application. Any user can be connected to any node over this network. The nodes all have access to two or more copies of the database.

What is replication active/active active-passive?

“Active-Active” vs. Active-passive replication means one-way replication from a master database that is being actively updated to a slave database that is not updated except by the replication process. This is also called “master-slave” replication.

What are active clusters?

Active-active clustering is a data resiliency architecture in which client workloads are distributed across two or more nodes in a cluster to keep your data safe and available in the event of an unexpected component failure.

What is difference between active-active and active/passive cluster SQL Server?

The actual difference between active/passive and active/active is just that in active/passive all business logic runs on one node and the “passive” node just waits for a failover.

What are active and passive nodes?

Active/passive clusters are groups of computing resources that are implemented to provide high availability of software and hardware computing services. When the active node fails, the cluster can fails over to one of the inactive nodes.

What is active-passive?

Active voice means that a sentence has a subject that acts upon its verb. Passive voice means that a subject is a recipient of a verb’s action. The two grammatical voices are active and passive. Write with confidence.

What is an active-passive cluster?

Is Oracle RAC active-active?

Oracle RAC uses an active-active architecture that enables multiple database instances, each running on different nodes, to simultaneously read and write to the same database.

What is active and passive firewall?

Active/Passive — One firewall actively manages traffic while the other is synchronized and ready to transition to the active state, should a failure occur. In this mode, both firewalls share the same configuration settings, and one actively manages traffic until a path, link, system, or network failure occurs.

What is the difference between active/passive clustering and Active/Active Clustering?

This is different from active/passive clustering where only one member of a cluster provides service to users at a time. Active/passive is the preferred recommended cluster configuration. In an active/passive cluster, the cluster includes at least one passive node and one or more active nodes.

What is the difference between active-active and active-passive configuration?

Like the active-active configuration, active-passive also consists of at least two nodes. However, as the name “active-passive” implies, not all nodes are going to be active. In the case of two nodes, for example, if the first node is already active, the second node must be passive or on standby.

What is an active active high availability cluster?

Active-Active high availability cluster. An active-active cluster is typically made up of at least two nodes, both actively running the same kind of service simultaneously. The main purpose of an active-active cluster is to achieve load balancing.

What is the difference between active-passive and passive failover?

The passive (failover) server serves as a backup that’s ready to take over as soon as the active (primary) server gets disconnected or is unable to serve, an active-passive failover for when a node fails. When clients connect to a two-node cluster in active-passive configuration, they only connect to one server.
