Commercial Database MigrationsĪmazon provides you with the capabilities needed to migrate your PostgreSQL database workloads to Aurora. RDS provides automated migration tools to convert existing RDS PostgreSQL databases to Aurora PostgreSQL. It takes care of database management concerns like setup, patching and upgrades, backup and recovery, failover, and high availability. It can run as part of Amazon RDS, and is also provided in a serverless model, known as Aurora Serverless.Īurora PostgreSQL is a fully managed service that lets you operate and easily scale existing and new PostgreSQL databases. AWS Aurora PostgreSQLĪmazon Aurora PostgreSQL is an Amazon-developed database engine that is compatible with PostgreSQL and fully complies with ACID requirements (Atomicity, Consistency, Isolation, Durability). To ensure consistency, any changes to the instance source are propagated to all associated read replicas. You can then serve read traffic from multiple data copies, and increase the aggregate read throughput of your application. To do this, you need to create one or more replicas of your source database instance. The read replicas feature can help you provision read-heavy databases beyond the capacity of a single instance. This allows RDS to failover to the updated standby if your main database fails.
Any database updates will be then made concurrently on both the main and standby databases. The system automatically creates and manages a replica of your database and puts it in “standby” within another availability zone. Once you enable this feature, RDS starts automatically creating and modifying your DB instance, to ensure database availability. In addition to automated backups and DB snapshots, RDS provides features for replication, including multi-AZ deployments and read replicas. RDS stores DB snapshots until you delete them, and lets you copy snapshots across available AWS regions for disaster recovery and migration purposes. DB snapshots-the system lets you create snapshots as backups for each DB instance.Automated backups store copies of the database and transaction logs, and you can specify a retention period of up to 35 days.
Automated backups-by default, Amazon RDS is configured to automatically create point in time copies of DB instances, which you can later restore as needed.There are several backup and recovery options available when using RDS PostgreSQL, including: RDS provides you with features to simplify and automate the process. You can easily deploy new databases and migrate your existing applications and tools. You get to use all of the familiar features of PostgreSQL, and leverage RDS management capabilities. Easy Managed DeploymentsĪmazon RDS for PostgreSQL lets you easily run your PostgreSQL database on Amazon RDS DB Instances. You can manage your RDS PostgreSQL instances using standard management utilities such as pgAdmin or psql. Amazon does not provide access to the physical hosts running the database instances (for example, using SSH). It provides automated backups, and lets you easily create database snapshots, with point in time restore. AWS RDS PostgreSQLĪmazon RDS lets you deploy fully managed PostgreSQL database instances.

We’ll also cover Babelfish with Aurora, an innovative service that lets you migrate Microsoft SQL Server databases to PostgreSQL and save on license costs. Let’s explore the two main options for deploying PostgreSQL on AWS as a managed service - Amazon Relational Database Service (RDS), and Amazon Aurora. Managed PostgreSQL Options on AWS: RDS and Aurora
The most recent major release is PostgreSQL 12.Īmazon Web Services (AWS) provides PostgreSQL as a fully managed AWS database service, using Amazon Relational Database Service (RDS) and Amazon Aurora, an Amazon-developed database engine which is fully compatible with PostgreSQL. PostgreSQL is used as a primary data repository for many web, mobile, geospatial, and analytics applications. PostgreSQL is highly reliable and is known for its integrity and accuracy, having been developed over 20 years by a large open-source community. PostgreSQL is a high-performance, enterprise-class open-source relational database that supports both SQL (relational) and JSON (non-relational) queries.
