Comparison Aurora vs. RDS
In this part of the article, we will compare various Aurora and RDS features and metrics so you will have a better understanding of these databases.
Performance
In the realm of database applications, subpar performance is far from ideal. Let's begin by discussing a pivotal performance aspect of these two databases. Amazon Aurora offers 3x the throughput of PostgreSQL or 5 times that of standard MySQL when running on comparable hardware. AWS RDS offers 3x faster than MySQL, and 2x faster than PostgreSQL.
What does "five times the performance of MySQL" mean?
AWS tests with SysBench on r3.8xlarge instances show that Amazon Aurora delivers over 500,000 SELECTs/sec and 100,000 UPDATEs/sec, 5 times higher than MySQL running the same benchmark on the same hardware. Detailed instructions on this benchmark and how to replicate it yourself are provided in the Amazon Aurora MySQL-Compatible Edition Performance Benchmarking Guide.
What does "three times the performance of PostgreSQL" mean?
AWS tests with SysBench on r4.16xlarge instances show that Amazon Aurora delivers SELECTs/sec and UPDATEs/sec over three times higher than PostgreSQL running the same benchmark on the same hardware. Detailed instructions on this benchmark and how to replicate it yourself are provided in the Amazon Aurora PostgreSQL-Compatible Edition Performance Benchmarking Guide.
RDS employs SSDs in its database services to enhance IO throughput. Amazon RDS allows users to select from two SSD-backed storage choices: one tailored for high-performance OLTP applications and the other designed for cost-effective general-purpose use.
| Performance | AWS Aurora | AWS RDS |
|---|---|---|
| Speed | Up to 5x faster than MySQL, 3x faster than PostgreSQL | Up to 3x faster than MySQL, 2x faster than PostgreSQL |
| Latency | Low latency for both reads and writes | Higher latency for reads than writes |
| Throughput | High throughput for both reads and writes | Higher throughput for writes than reads |
| Scalability | Horizontally and vertically scalable | Horizontally scalable only |
The architecture of RDS closely resembles the manual installation of a database engine on Amazon EC2, with the key distinction being that AWS handles provisioning and maintenance. RDS offers a plethora of features, including automatic failover and backups. It relies on Amazon EBS volumes for the storage of databases and logs. The Multi-AZ feature must be enabled on your RDS instance to ensure reliability, facilitating synchronous replication to a standby replica in a different Availability Zone.
Aurora's database storage is inherently reliable and fault-tolerant, regardless of the instances. Within this tool, data is redundantly distributed across three Availability Zones in six copies, each consisting of 10GB chunks. This robust redundancy mechanism ensures data durability, even if you operate just a single Aurora instance.
Compatibility with database engines
It's crucial to grasp the compatibility of different database types with Aurora and RDS. When transitioning your on-premises databases to the cloud or migrating from RDS to Amazon Aurora, it's essential to adhere to your service-level agreements (SLAs) with minimal to no downtime.
Aurora integrates with two database management systems, PostgreSQL and MySQL, specifically versions 9.6.1 and 5.6. This compatibility allows you to run your existing database tools and applications on Aurora without requiring any modifications.
In contrast, when dealing with Amazon RDS, migrating from EC2-hosted or on-premises databases like PostgreSQL, SQL Server, or MySQL mandates using AWS Database Migration Service.
Storage auto-scaling
Amazon Aurora exhibits impressive flexibility in storage capacity, ranging from a minimum of 10 GB to a maximum of 128 TB, depending on your database usage. Moreover, this scaling occurs in 10 GB increments without adversely impacting database performance. Importantly, there's no need to allocate storage in advance, alleviating the burden of database administrators in predicting and provisioning storage for uninterrupted business operations.
In contrast, RDS necessitates database administrators to provision storage on the fly, even up to 6 TB, with no downtime. However, it's worth noting that Aurora exclusively supports the InnoDB storage engine and automatically converts tables from other storage engines into InnoDB.
Resiliency
Aurora is more resilient than RDS because of its architectural design. It has a fast recovery from failures. If a compute node crashes, Aurora can recover quickly. It can start new read replicas with minimal lag, and if the writer fails, another replica can be promoted to take over without waiting for the other nodes to reach a consensus. All the shared state is in the data nodes, so failed nodes can be replaced almost immediately.
Replication
Aurora offers two types of replicas that utilize the same underlying volume as the primary instance. All Aurora replicas instantly reflect any updates made on the primary instance. Aurora provides the flexibility to provision up to 15 replicas, and this replication process occurs in a matter of milliseconds. Additionally, Aurora automates failover procedures to prevent any potential data loss.
In contrast, RDS permits only five replicas, and the replication process is comparatively slower when compared to Amazon Aurora. RDS requires manual intervention for failover, which may result in data loss occurring at the last moment.
Failover
In RDS, manual intervention is necessary to initiate failover to a read replica, potentially resulting in data loss. However, you can employ the Multi-AZ feature (Standby instance) to enable automatic failover and mitigate the risk of downtime and data loss.
Conversely, Aurora automates the failover process to a read replica to prevent data loss. Moreover, Aurora boasts a faster failover time.
Cluster endpoints
In RDS, a cluster endpoint is designated for writing queries, serving as the DNS endpoint directing to the current master database instance. During a failover event, RDS seamlessly redirects this endpoint to the new master through a straightforward DNS adjustment. However, for read replicas in RDS, the application load balancing is responsible for handling instance endpoints, as RDS lacks a dedicated load balancer for read replicas.
On the other hand, Aurora follows a similar approach for writing queries, utilizing the cluster endpoint. Additionally, it offers a reader endpoint that acts as an automatic load balancer for read replicas, simplifying the management of read queries. In the event of a failover in Aurora, one of the read replicas assumes the role of the master and is removed from the reader set.
Backup
RDS generates and stores automated backups of your DB instance within the designated backup window. These backups encompass the entire DB instance, not just individual databases, aligning with your specified backup retention period. You have the flexibility to restore your database to any specific point in time within this retention period. It's worth noting that there might be temporary interruptions in storage I/O during the snapshot process, potentially affecting database performance.
In contrast, Aurora automatically backs up your cluster volume and retains restored data throughout the backup retention period. These backups are continuous and incremental, allowing for swift restoration to any desired point within the retention period. Importantly, there are no performance impacts or service interruptions during the backup data writing process.
Both store their backups in Amazon S3.
Pricing
AWS offers various instance types tailored to different database engines. For example, AWS RDS follows a pay-as-you-go model, allowing you to try it for free using the AWS Free Tier without extra charges. On the other side, Aurora does not have a Free Tier period, so you need to select the required plan.
Aurora is often more expensive than RDS for similar workloads and is calculated based on the instance type, size, and EBS volume. Aurora pricing is mostly decided by instance size, with service charges based on actual usage. You can find more information on AWS Pricing Calculator and Amazon RDS pricing.
