AWS increases Epic database sizing options for customers

Amazon Web Services (AWS), in collaboration with Epic, is announcing another increase in Epic on AWS customer database sizing, measured in global references per second (GRefs/s).

Epic’s Chronicles Operational Database (ODB) can now be sized to 75 million GRefs/s in AWS. This is achieved on an Amazon Elastic Compute Cloud (EC2) R7an.48xlarge instance combined with Amazon Elastic Block Store (EBS) io2 Block Express volumes, all within a horizontally scaled (ECP) ODB architecture. This announcement sets a new bar for public cloud sizing using native cloud services. For customers running Epic’s Chronicles ODB in single server mode (SMP), AWS delivered a sizing increase up to 47.3M GRefs/s. This represents a 68% increase in SMP and an 36% increase in ECP sizing since our previous update in October 2023. In total, AWS has increased our ECP sizing by 150% over the past 12 months. AWS’ global infrastructure design also provides at least 3 Availability Zones in every AWS Region, allowing for highly available infrastructure deployment to support Epic system resiliency.

The R7an instances are powered by 4th Gen AMD EPYC processors and built on the AWS Nitro System. The Nitro System is a lightweight hypervisor that provides improved compute and networking performance for EC2 instances. Nitro enables the delivery of efficient and flexible cloud services with enhanced security, isolated multi-tenancy, private networking, and fast local storage.

io2 Block Express is the next generation of EBS storage server architecture. It has been built for the purpose of meeting the performance requirements of I/O intensive applications. io2 Block Express minimizes I/O delay and latency variation (network jitter) and delivers up to 2.5x better average I/O latency than major cloud providers, providing faster and more consistent performance for your applications. These volumes provide sub-millisecond latency and larger capacity, IOPS, and throughput than other AWS volume types.
