Deep dive on Amazon RDS Multi-AZ with two readable standbys - AWS Online Tech Talks

Amazon Relational Database Service (Amazon RDS) for PostgreSQL and for MySQL now support a new Amazon RDS Multi-AZ deployment option with one primary and two readable standby database (DB) instances across three Availability Zones (AZs). With this new option, Amazon RDS users can get up to 2x faster transaction commit latency compared to Multi-AZ with one standby, typically under 35 second fail overs, and additional read capacity. In this session, deep dive into how this new deployment option works, how it’s different from Amazon RDS Multi-AZ with one standby, and see a demo of how this option can help with applications with read-heavy workloads.

Learning Objectives:
* Objective 1 - Get an overview of Amazon RDS Multi-AZ and the new two readable standbys option.
* Objective 2 - Compare Amazon RDS Multi-AZ with one standby and Amazon RDS Multi-AZ with two readable standbys to see which is best for your use case.
* Objective 3 - Watch a demo of this new deployment option and how it helps applications with read-heavy workloads.

In the second option, if the replication is not sync, does it still provide monotonic read consistency on read replicas?

[jee.lalitha]

In this architecture, the two readable standbys are also acting as read replicas?

[tharun]

In the first option if synchronous replication is used, wouldn't the availability be affected in case the standby replica fails?

Don't we have this for sql server engine ?

Can you create a read replica in a different region for DR? How does RDS Cluster support disaster recovery?
