# Amazon RDS for PostgreSQL

PostgreSQL has become the preferred open source relational database for many enterprise developers and start-ups, powering leading business and mobile applications. Amazon RDS makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. With Amazon RDS, you can deploy scalable PostgreSQL deployments in minutes with cost-efficient and resizable hardware capacity. Amazon RDS manages complex and time-consuming administrative tasks such as PostgreSQL software installation and upgrades; storage management; replication for high availability and read throughput; and backups for disaster recovery.\


Amazon RDS for PostgreSQL gives you access to the capabilities of the familiar PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS for PostgreSQL currently supports PostgreSQL 9.6, 10, 11, 12, 13, 14 and 15.\


## Benefits <a href="#benefits" id="benefits"></a>

#### Easy, managed deployments <a href="#easy.2c_managed_deployments" id="easy.2c_managed_deployments"></a>

It takes only a few clicks in the Amazon Web Services Management Console to launch and connect to a production-ready PostgreSQL database in minutes. Amazon RDS for PostgreSQL database instances are pre-configured with parameters and settings for the server type you have selected. Database parameter groups provide granular control and fine-tuning of your PostgreSQL database.\


#### Fast, predictable storage <a href="#fast.2c_predictable_storage" id="fast.2c_predictable_storage"></a>

Amazon RDS provides two SSD-backed storage options for your PostgreSQL database. General Purpose storage provides cost-effective storage for small or medium-sized workloads. For high-performance OLTP applications, Provisioned IOPS delivers consistent performance of up to 80,000 IOs per second. As your storage requirements grow you can provision additional storage on-the-fly with zero downtime.\


#### Backup and recovery <a href="#backup_and_recovery" id="backup_and_recovery"></a>

The automated backup feature of Amazon RDS enables recovery of your PostgreSQL database instance to any point in time within your specified retention period of up to thirty five days. In addition, you can perform user-initiated backups of your DB Instance. These full database backups will be stored by Amazon RDS until you explicitly delete them.\


#### High availability and read replicas <a href="#high_availability_and_read_replicas" id="high_availability_and_read_replicas"></a>

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for your PostgreSQL databases, making them a natural fit for production database workloads. Amazon RDS Read Replicas make it easy to elastically scale out beyond the capacity constraints of a single database instance for read-heavy database workloads.\


#### Monitoring and metrics <a href="#monitoring_and_metrics" id="monitoring_and_metrics"></a>

Amazon RDS for PostgreSQL provides [Amazon CloudWatch](https://www.amazonaws.cn/en/cloudwatch/) metrics for your database instances at no additional charge and Amazon RDS Enhanced Monitoring provides access to over 50 CPU, memory, file system, and disk I/O metrics. View key operational metrics in Amazon Web Services Management Console, including compute/memory/storage capacity utilization, I/O activity, and instance connections.\


#### Isolation and security <a href="#isolation_and_security" id="isolation_and_security"></a>

As a managed service, Amazon RDS provides a high level of security for your PostgreSQL databases. These include network isolation using [Amazon Virtual Private Cloud (VPC)](https://www.amazonaws.cn/en/vpc/), encryption at rest using keys you create and control through [Amazon Key Management Service (KMS)](https://www.amazonaws.cn/en/kms/) and encryption of data in transit using SSL.
