The main difference between Amazon RDS and Aurora Serverless is that the more traditional RDS gives developers the option to choose database instance type and size. You can also select a database engine, including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle and Microsoft SQL Server.
Factors to consider before choosing
First and foremost, Aurora Serverless is only compatible with MySQL and PostgreSQL. If an application requires Oracle, SQL Server or MariaDB, then you need to use Amazon RDS.
Overview
Amazon RDS for PostgreSQL and Aurora PostgreSQL are fully managed open-source PostgreSQL database services. They both offer provisioning various types of database instances, multiple PostgreSQL versions, managing backups, point-in-time recovery (PITR), replication, monitoring, Multi-AZ support, and Storage Auto Scaling.
Scalability
Amazon RDS read replicas help reduce the load on the primary DB instance by offloading your read workloads to the read replica DB instances. It makes it easy to scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads.
Crash recovery
In Amazon RDS for PostgreSQL, during crash recovery, it replays the transaction logs since the last checkpoint. A checkpoint flushes the current in-memory modified database blocks and WAL information from memory to disk, which provides durability in case the database crashes for obvious reasons.
Failover
Amazon RDS for PostgreSQL handles failover automatically so that applications can resume database operations as quickly as possible. The failover time is typically around 60–120 seconds. This consists of failure detection, DNS propagation, and crash recovery. The failover time mainly depends on how long it takes to perform crash recovery.
Storage
Amazon RDS for PostgreSQL supports Amazon EBS solid state drive (SSD)-based storage types: General Purpose SSD and Provisioned IOPS. General Purpose SSD storage delivers a consistent baseline of 3 IOPS per provisioned GB and can burst up to 3,000 IOPS. The baseline IOPS limit for General Purpose SSD is 16,000 IOPS.
High availability and disaster recovery
Amazon RDS for PostgreSQL provides high availability and disaster recovery (DR) features by using Multi-AZ deployments, read replicas, and sharing snapshots. Multi-AZ configuration synchronously replicates data to a standby instance in a different Availability Zone. Automated backups are taken from the standby instance.
Backup
Amazon RDS automatically takes daily backups of PostgreSQL instances during a backup window. There is a slight performance impact when the backup initiates for single Availability Zone deployments. In addition, it also backs up transaction logs (WALs).
