What is active-active disaster recovery?
Active-Active Disaster Recovery An active-active, or stretched clustering, configuration is the deployment of a second identical live infrastructure which continually replicates with the first site. This framework will typically consist of only two sites.
What is active/passive DR site?
In a disaster recovery environment, the cluster on the primary site provides data and services during normal operation; the cluster on the secondary site provides data and services if the primary cluster fails. When a failure occurs at the primary site, the DR solution is activated.
What is an active-active configuration?
An active/active configuration consists of two or more servers actively running a different database instance with each serving as a backup for each other. The database instances must be on different shared physical disks.
What is active-active environment?
When multiple copies of an application are run in an environment, the environment is known as an active-active environment. Traditionally, applications had to be built to support the concept, and had to be run using some of the most expensive combinations of software and hardware available on the market.
What is active-active in AWS?
In active-active failover, all the records that have the same name, the same type (such as A or AAAA), and the same routing policy (such as weighted or latency) are active unless Route 53 considers them unhealthy. Route 53 can respond to a DNS query using any healthy record.
How do you check if the cluster is active-active or active passive?
correct terms for A/A is multi instance cluster so if your cluster has Multiple SQL Server instance it should be Multi instance cluster generally cluster with single instance and two nodes of which one is active and other is passive will be A/P cluster. In a multi instance cluster both instances can be on same node.
What is active-active datacenter?
The term active-active refers to the use of at least two data centers where both can service an application at any time, so each functions as an active application site. This means the application continues to be accessible even if parts of the network or servers fail unexpectedly.
What is the active-active cluster?
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.
Is high availability active-active?
Active/Passive is called a “high availability” solution. The downtime is very minuscule, but there is still a little time between when the first node fails and the secondary node picks up the traffic.
What is active failover?
In Active/Active Failover, the system or network that’s being secured is divided in half, and the two pieces of equipment take responsibility for half, while still standing by to provide failover for the other part.
Is always on active-active?
AlwaysOn Is the New Active/Passive and Active/Active.
How do you check if the cluster is active-active or active-passive?
When does an active region become a recovery site?
If a disaster event occurs and the active Region cannot support workload operation, then the passive site becomes the recovery site (recovery Region). We then take steps so that our workload can run from there. All requests are now switched to be routed there in a process called “failover.”
How to create a disaster recovery plan for Active Directory?
You can first fail over Active Directory using Site Recovery. Then, fail over the other applications, using application-specific recovery plans. This article explains how to create a disaster recovery solution for Active Directory. It includes prerequisites, and failover instructions.
When to use site recovery for Active Directory?
If you have deployed Active Directory for multiple applications in your primary site, for example, for SharePoint and SAP, you might want to fail over the complete site. You can first fail over Active Directory using Site Recovery. Then, fail over the other applications, using application-specific recovery plans.
What do you need to know about disaster recovery?
If your definition of a disaster goes beyond the disruption or loss of a physical data center to that of a Region or if you are subject to regulatory requirements that require it, then you should consider Pilot Light, Warm Standby, or Multi-Site Active/Active.
