Traditionally, relational databases were designed for scale-up architectures. Supporting more clients or higher throughput required an upgrade to a larger server. Until recently, this meant that implementing a read & write scale-out architecture either required a NoSQL database and abandoning traditional relational database benefits, or relying on sharding and explicit replication. There were no solutions that could scale-out and still provide complete ACID (Atomicity, Consistency, Isolation, and Durability) -compliant semantics. This tension is what inspired the NewSQL movement and ultimately led to today’s modern “elastic SQL” databases.
NuoDB is an elastic SQL database designed with distributed application deployment challenges in mind. It’s a full SQL solution that provides all the properties of ACID-compliant transactions and standard relational SQL language support. It’s also designed from the start as a distributed system that scales the way a cloud service has to scale, providing high availability and resiliency with no single points of failure. Different from traditional shared-disk or shared nothing architectures, NuoDB’s patented database presents a new kind of peer-to-peer, on-demand independence that yields high availability, low-latency, and a deployment model that is easy to manage.
This article highlights the key concepts and architectural differences that set NuoDB apart from traditional relational databases and even other elastic SQL databases.
