Amazon Aurora DSQL provides a distributed SQL database with 99.999% availability across multiple regions, virtually unlimited scalability, high consistency, and zero infrastructure management
LAS VEGAS – December 3, 2024 –In AWS re:Invent, Amazon Web Services, Inc. (AWS), an Amazon.com, Inc. company. (NASDAQ: AMZN), today announced new capabilities for Amazon Aurora and Amazon DynamoDB to support the most demanding customer workloads that need to operate across multiple regions with high resilience, low latency and maximum availability, whether they want SQL or NoSQL.
- Amazon Aurora DSQL is a new serverless distributed SQL database that enables customers to build applications with high availability, high durability, PostgreSQL support, and four times faster reads and writes than other databases distributed SQL.
- Amazon DynamoDB global tables now support strong persistence across multiple regions, ensuring that cross-region customer applications always read the most recent data without having to change any application code.
- AWS customers including Autodesk, Electronic Arts, Klarna, QRT and Razorpay are exploring Aurora DSQL to support their rapidly growing businesses.
“Databases are a critical element of any application, and customers rely on AWS to power their most critical workloads,” said G2 Krishnamoorthy, vice president of Database Services, AWS. “Over the years, we’ve innovated to provide customers with the broadest range of high-performance, scalable databases, including Amazon Aurora, which hundreds of thousands of customers rely on every day. Aurora eliminates the need for customers to compromise by providing the performance of enterprise-grade commercial databases with the flexibility and economics of open source. Now, we’re reinventing the relational database to deliver robust durability, global availability, and virtually unlimited scalability, without having to choose between low latency or SQL.”
Amazon Aurora DSQL enables highly resilient applications that meet the most stringent business continuity requirements
Amazon Aurora is a cloud-based relational database that provides all the performance and capacity of a high-end commercial database, with the flexibility and cost-effectiveness of an open source database. However, as customers develop more and more real-time, globally distributed applications with millions of end users worldwide, they continue to push the boundaries of relational databases and want more from Aurora. They want a multi-regional database with low latency, strong resilience, high availability and zero operational overhead – and it has to be SQL. The options available today require compromises. Some offer low latency and high availability, but without robust persistence or SQL support. Others offer strong resiliency and high availability, but cannot avoid very high latency and still lack SQL support. Now, however, customers no longer have to compromise with Aurora DSQL, the fastest distributed SQL database that offers extreme durability, four times faster reads and writes than other distributed SQL databases popular, 99.999% availability in many regions, virtually unlimited scalability and zero infrastructure management.
Aurora DSQL’s active-active architecture and automatic error recovery ensure that a client application is always available by allowing it to read and write to the final point from Aurora DSQL. All transactions written in one Region are mirrored in other Regions with great consistency.
With Aurora DSQL, there’s no need to provision, patch, or manage database instances, and all updates and security patches are performed non-disruptively and without performance impact. Aurora DSQL automatically scales to meet any workload demand without database partitioning or instance upgrades, and can scale reads and writes independently, eliminating scaling bottlenecks while maintaining performance. Aurora DSQL is compatible with PostgreSQL and provides an easy-to-use developer experience.
To make this possible, AWS had to reinvent relational database transaction processing. Aurora DSQL overcomes two long-standing challenges of distributed databases: achieving robust consistency across multiple regions with low latency and synchronizing servers with microsecond accuracy around the world. To achieve robust persistence across multiple low-latency regions, Aurora DSQL decouples transaction processing from storage to overcome the limitations of current approaches, which were limited by information being transmitted back and forth multiple times at the speed of light. To overcome this, Aurora DSQL only verifies each transaction at commit time and at that time parallelizes all writes across all regions to ensure a multi-region database with strong consistency and fast writes. To ensure that each region sees each database operation in the exact order in which it occurred, Aurora DSQL uses Amazon’s time synchronization service, which adds hardware reference clocks to each Amazon Elastic Compute Cloud instance (EC2), synchronizing them with satellite-linked atomic clocks. to ensure accurate time to the microsecond level anywhere in the world. By solving these challenges, Amazon Aurora DSQL enables customers to build global distributed applications at a whole new scale.
For example, Razorpay, one of the largest fintech companies in India, is looking to use Aurora DSQL to power new solutions fintechhelping them build resilient applications that can scale quickly to meet the needs of their growing user base. Aurora DSQL will help Razorpay achieve strong consistency across multiple Regions, which is critical for financial use cases that require high degrees of accuracy for their applications, while operating more efficiently on a global scale.
Amazon DynamoDB global tables now support robust persistence across multiple regions
DynamoDB was the first fully managed, serverless NoSQL database that transformed what Internet-scale applications could achieve by redefining performance and simplifying operations with zero infrastructure management and consistent single-digit millisecond performance at every scale. Today, customers in nearly every industry and size are building and modernizing their mission-critical applications by leveraging DynamoDB’s global tables, a multi-active, multi-region database that delivers 99.999% availability. AWS is now using the same underlying technology that Aurora DSQL uses to enhance DynamoDB global tables, adding the option for robust high-availability, virtually unlimited scalability, and zero infrastructure management already available in DynamoDB global tables.
The AWS Reltio client processes more than 9 billion customer profiles for market research and 60 billion API calls each year. In 2020, Reltio launched on Amazon DynamoDB to improve the performance, scalability and security of its database solution. Now, as Reltio continues to expand globally, the company plans to leverage the robust multi-region resilience in global DynamoDB tables to meet the stringent resiliency and performance requirements of its growing customer base.
Both Amazon Aurora DSQL and strong multi-region consistency on Amazon DynamoDB global tables are available in preview today.
