Amazon Aurora DSQL provides a distributed SQL
database with 99.999% multi-Region availability, virtually
unlimited scalability, strong consistency, and zero infrastructure
management
At 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
customers’ most demanding workloads that need to operate across
multiple Regions with strong consistency, low latency, and the
highest availability whether they want SQL or NoSQL.
- Amazon Aurora DSQL is a new serverless, distributed SQL
database that enables customers to build applications with the
highest availability, strong consistency, PostgreSQL compatibility,
and 4x faster reads and writes compared to other popular
distributed SQL databases.
- Amazon DynamoDB global tables now supports multi-Region strong
consistency, ensuring customers' multi-Region applications are
always reading the latest 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 foundational building block of every
application, and customers rely on AWS databases to power their
most critical workloads,” said G2 Krishnamoorthy, vice president of
Database Services at AWS. “Over the years, we have innovated to
provide customers with the widest range of high-performance and
scalable databases, including Amazon Aurora, which hundreds of
thousands of customers rely on every day. Aurora removes the need
for customers to make trade-offs by providing the performance of
enterprise grade commercial databases with the flexibility and
economics of open source. Now, we’re reimagining the relational
database again to deliver strong consistency, 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-native relational database that
delivers all of the performance and capability of a high-end
commercial database, with the flexibility and cost-effectiveness of
an open source database. However, as customers increasingly build
globally distributed, real-time applications with millions of end
users around the world, they continue to push the limits of
relational databases and want more from Aurora. They want a
multi-Region database with low latency, strong consistency, high
availability, and zero operational burden—and it has to be SQL. The
options available today force trade-offs. Some provide low latency
and high availability, but not strong consistency or SQL
compatibility. Others provide strong consistency and high
availability, but can’t avoid very high latency and still don’t
offer SQL compatibility. Now, customers no longer have to
compromise with Aurora DSQL, the fastest distributed SQL database
that delivers strong consistency, 4x faster reads and writes
compared to other popular distributed SQL databases, 99.999%
multi-Region availability, virtually unlimited scalability, and
zero infrastructure management.
Aurora DSQL’s active-active architecture and automated failure
recovery ensure that a customer’s application is always available
by enabling an application to read and write to any Aurora DSQL
endpoint. All transactions written in one Region are reflected in
other Regions with strong consistency. With Aurora DSQL, there is
no need to provision, patch, or manage database instances, and all
updates and security patching happen with no downtime and zero
impact to performance. Aurora DSQL automatically scales to meet any
workload demand without database sharding or instance upgrades, and
can scale reads and writes independently, eliminating scaling
bottlenecks while maintaining performance. Aurora DSQL is
PostgreSQL compatible, offering an easy-to-use developer
experience.
To make this possible, AWS had to reinvent relational database
transaction processing. Aurora DSQL overcomes two historical
challenges of distributed databases—achieving multi-Region strong
consistency with low latency, and syncing servers with microsecond
accuracy around the globe. To achieve multi-Region strong
consistency with low latency, Aurora DSQL decouples transaction
processing from storage to overcome the limitations of the current
approaches, which were constrained by information being passed back
and forth multiple times at the speed of light. To overcome this,
Aurora DSQL only checks each transaction at commit time and, on
commit, parallelizes all the writes across all regions to provide a
multi-Region database with strong consistency and fast writes. To
ensure each Region sees every database operation in the exact order
they occurred, Aurora DSQL uses Amazon Time Sync Service, which
added hardware reference clocks on every Amazon Elastic Compute
Cloud (EC2) instance, synchronizing them to satellite-connected
atomic clocks to provide microseconds level accurate time within
anywhere in the world. By solving these challenges, Amazon Aurora
DSQL enables customers to build globally distributed applications
on an entirely new scale.
For example, Razorpay, one of the largest fintech companies in
India, is looking to use Aurora DSQL to power new fintech
solutions, helping them create resilient applications that can
rapidly scale to support the needs of their growing user base.
Aurora DSQL will help Razorpay achieve multi-Region strong
consistency, which is critical for financial use cases that require
high degrees of precision, for their applications while operating
more efficiently at a global scale.
Amazon DynamoDB global tables now supports multi-Region
strong consistency
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 any scale. Today, customers across virtually every
industry and size are building and modernizing their critical
applications by leveraging DynamoDB global tables, a multi-Region,
multi-active database that provides 99.999% availability. AWS is
now using the same underlying technology leveraged by Aurora DSQL
to enhance DynamoDB global tables, adding the option of strong
consistency to the highest availability, virtually unlimited
scalability, and zero infrastructure management already available
in DynamoDB global tables.
AWS customer Reltio processes more than 9 billion customer
profiles for market research and 60 billion API calls annually. In
2020, Reltio went all-in on Amazon DynamoDB to enhance the
performance, scaling, and security of its database solution. Now,
as Reltio continues to expand globally, the company plans to
leverage multi-Region strong consistency in DynamoDB global tables
to meet the stringent resilience and performance requirements of
its growing customer base.
Both Amazon Aurora DSQL and multi-Region strong consistency in
Amazon DynamoDB global tables are available in preview today.
