1 week ago - You can create an Aurora PostgreSQL cluster using the Amazon RDS Console or AWS CLI or RDS API with I/O-Optimized storage and use the Optimized Reads instance class (db.r8gd), which indicates the instance provides local NVMe SSD storage. For existing Aurora PostgreSQL clusters, you can upgrade to db.r8gd instances through an instance class modification with minimal downtime by using Aurora high availability features with the following options:

2 days ago - Aurora has 5x the throughput of MySQL and 3x of PostgreSQL with full PostgreSQL and MySQL compatibility. Aurora also offers DSQL, the fastest distributed SQL database that is PostgreSQL-compatible. Aurora is designed for up to 99.999% multi-Region availability.

An Aurora primary DB cluster in one Region and up to 10 read-only secondary DB clusters in different Regions by using an Aurora global database. Aurora PostgreSQL doesn't support cross-Region Aurora Replicas. However, you can use Aurora global database to scale your Aurora PostgreSQL DB cluster's read capabilities to more than one AWS Region and to meet availability goals.

September 27, 2024 - To further improve uptime, the team created an Aurora PostgreSQL replica in a second Availability Zone in each Region. These replicas are continuously and durably replicated from the writer instance, and are able to take over as the writer in seconds, allowing the workload to keep running in the primary Region, thanks to the design of the Aurora storage system. To further improve high availability during in-Region failovers, the team used Amazon RDS Proxy, which is a Regional service that sits between the application and Aurora PostgreSQL cluster.

May 17, 2023 - The following design is highly scalable and durable, exclusively addressing high availability but not disaster recovery. The AWS Global Infrastructure is always growing and to get an understand of its reach please see this diagram of the footprint. This diagram shows the High Available setup of an Amazon Aurora cluster with read replicas in two of the availability zones.

October 31, 2024 - Aurora PostgreSQL Limitless Database scales a node up to a higher capacity when its current utilization is too low to handle the load. It scales the node down to a lower capacity when its current capacity is higher than needed.

May 17, 2024 - Aurora PostgreSQL supports up to 15 readers for scaling out read workloads and high availability within a single AWS Region. Aurora provides this by scaling storage across three Availability Zones in the AWS Region.

MySQL and PostgreSQL compatibility. Aurora provides managed high · availability (HA) and disaster recovery (DR) capabilities in and across AWS

1 week ago - Aurora provides an ideal environment ... close match to those of commercial database engines, and delivers the enterprise-grade performance, durability, and high availability required by most enterprise database workloads....

It merges the performance and ... open-source databases. High Performance: Delivering up to five times the throughput of standard MySQL and up to three times that of standard PostgreSQL....

Read scaling and high availability depend on minimal lag time. You can monitor how far an Aurora Replica is lagging behind the writer DB instance of your Aurora PostgreSQL DB cluster by monitoring the Amazon CloudWatch ReplicaLag metric. Because Aurora Replicas read from the same cluster volume as the writer DB instance, the ReplicaLag metric has a different meaning for an Aurora PostgreSQL DB cluster.

As an alternative to modifying the DB instance class directly, you can minimize downtime by using the high availability features of Amazon Aurora. First, add an Aurora Replica to your cluster. When creating the replica, choose the DB instance class size that you want to use for your cluster. When the Aurora Replica is synchronized with the cluster, you then failover to the newly added Replica. To learn more, see Aurora Replicas and Fast failover with Amazon Aurora PostgreSQL.

March 16, 2025 - According to AWS, Aurora can deliver up to five times the throughput of standard MySQL and three times the performance of standard PostgreSQL - due to its distributed and highly available architecture.

2 days ago - Amazon Aurora is a relational database service that offers unparalleled high performance and high availability at global scale with full MySQL- and PostgreSQL-compatibility and PostgreSQL-compatible DSQL.

You can use the AWS Management ... DB instance and specifying a different AZ. For high availability across multiple AWS Regions, you can set up Aurora global databases....

July 26, 2023 - Pick your preferred Aurora-compatible MySQL or PostgreSQL version. Choose the DB instance size, storage capacity, VPC, and other configurations. Enable multi-AZ deployment for high availability...

October 29, 2024 - Aurora PostgreSQL is a version of PostgreSQL provided by AWS, offering faster performance, higher availability, and automatic scaling, while regular PostgreSQL doesn’t have these built-in cloud benefits.

If optimizations don't improve the instance metrics and mitigate the resource exhaustion, consider scaling up your DB instance before you reach its limits. For more information on available DB instance classes and their specifications, see Amazon Aurora DB instance classes.
