Can you configure a database instance to be both a read replica and a primary database instance for original instance?

Can you configure a database instance to be both a read replica and a primary database instance for original instance?

You can’t configure a DB instance to serve as a replication source for an existing DB instance. You can only create a new read replica from an existing DB instance.

What type of replication will the primary database use to replicate to the standby instance?

synchronous
Replication to a standby replica is synchronous which is highly durable. Endpoint of DB instance remains the same after a failover, the application can resume database operations without manual intervention.

How do I connect an instance to a database?

Open the RDS console and choose Databases to display a list of your DB instances. Choose the SQL Server DB instance name to display its details. On the Connectivity & security tab, copy the endpoint. Note the port number.

Will my standby RDS instance be in the same VPC as my primary?

Q: Will my standby be in the same Region as my primary? Yes. Your standby is automatically provisioned in a different Availability Zone of the same Region as your DB instance primary.

What will happen when the primary instance in multi-az goes down?

If a storage volume on your primary instance fails in a Multi-AZ deployment, Amazon RDS automatically initiates a failover to the up-to-date standby (or to a replica in the case of Amazon Aurora). DB Instance failover is fully automatic and requires no administrative intervention.

How to set up replication on a database?

In the event that a secondary replica transitions to the primary role, it must be configured so that the secondary can take over after a failover. All possible publishers will connect to the subscriber using a linked server. To create a linked server to the subscriber, SRV4 , run the below query on the possible publishers: SRV2 and SRV3.

How does merge replication work in SQL Server?

When the network connection is established between both database servers, merge replication agents detect changes made on both databases and modify databases to synchronize and update their state. Merge replication is similar to transactional replication, but data is replicated from the Publisher to the Subscriber and inversely.

What are the different types of replication in SQL Server?

MS SQL Server Replication Types. 1 Snapshot replication. Snapshot replication is used to replicate data precisely as it appears at the moment when the database snapshot was created. 2 Transactional replication. 3 Peer-to-peer replication. 4 Merge replication.

Is it possible to replication MS SQL Server 2008?

Replication will not work if you install MS SQL Server 2008 on the second machine. For example, if you want to configure MS SQL transactional replication, you can use the second database server (where the Subscriber is configured) of a version within two versions of the source database server on which the Publisher is configured.
