![]() To ensure availability, you must manually enable the Multi-AZ feature on your RDS instance and replicate it synchronously to a standby replica in another Availability Zone. In RDS, Amazon EBS volumes handle database and log storage. It keeps data separate from the instances and makes 6 data copies to 3 Availability Zones. RDS is compatible with MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle.Īurora provides a reliable and fault-tolerant architecture by design. You will only pay for what you use with Reserver or On-Demand Instances.Īurora is compatible with PostgreSQL and MySQL. You can try it with no minimum or upfront fees. RDS is a more cost-efficient option than Aurora. There’s also a more-cost efficient SSD-backed option that fits general-purpose use cases where high performance is not critical.Īurora is priced according to a pay-as-you-go principle. The first SSD-backed option provides high performance, which is still lower than the one provided by Aurora. This step helps Aurora’s performance stay consistent even when the loads increase dramatically. In Aurora, all replicas are stored within the same storage cluster, which reduces the replica lag to a minimum. One of the key features behind Aurora’s high performance is that the database service writes logs directly to the storage without keeping any log buffers. The throughput performance provided by Aurora is two times higher than the performance of PostgreSQL and five times higher than the performance of MySQL running on similar hardware. Based on their vast experience with both technologies, our database specialists have completed the table below. Now it’s time to review and compare the most critical features of Amazon Aurora and Amazon RDS. In a situation where there can be only one, it is important to thoroughly compare Aurora and RDS, evaluate their benefits, and understand how the two solutions respond to your needs. However, not all of our customers want to go with both relational database services. We handled this project in style and brough the customer the main benefits of both Aurora and RDS in a single project. In particular, we applied custom approaches to converting Java, C, Cobol, and Shell data bulk processing apps to Java code that was perfectly compatible with PostgreSQL. We thoroughly researched the infrastructure and converted them manually according to our custom practices. Some of these objects could not be converted automatically. The ABCloudz team used AWS SCT to automatically convert the objects from Oracle to PostgreSQL on Amazon Aurora and pre-configured Amazon RDS servers. ![]() ![]() Even though Amazon RDS is a more cost-efficient solution than Amazon Aurora, some customers prefer to pay more just to have all database management tasks handled by the provider. The reason was that these customers didn’t want to handle any database maintenance, configuration, and instance switches. Most of their customers were ready to run their database management systems on Amazon RDS, but some wanted to use Amazon Aurora. The edtech company needed to adjust their solutions to the needs of their customers. A complex database management system migration from Oracle to PostgreSQL involving Aurora and RDSĪBCloudz helped a large educational technology company migrate their customer-facing database management system from Oracle to PostgreSQL in an effort to cut their database maintenance cost. ![]() Keep reading to know which choice fits you best and when you should go with Aurora or RDS. In this article, we will compare the two technologies and tell you about their common use cases. Amazon RDS is close to being a fully managed solution, but it leaves some space for simple database configuration. It is also known for its strong emphasis on reliability and business continuity.Īmazon RDS, a distributed relational database service with which we have solid expertise, it allows its users to provision, setup, patch, and backup Aurora, MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle database engines on AWS. Aurora is a fully managed relational database that brings its users the performance and availability of traditional enterprise databases, as well as the simplicity and cost-effectiveness of open-source databases. But which Amazon relational database fits you best? The most common dilemma is choosing between Amazon Aurora and Amazon RDS.Īmazon Aurora is one of Amazon’s most rapidly developing database services. In our previous posts, we focused attention on different AWS services and the benefits of migrating to Amazon’s relational databases.
