Banks running large-scale risk and P&L analytics face pressure to reduce cloud infrastructure spending without compromising performance. As real-time and historical analytics continue to grow in scope, compute efficiency becomes a strategic priority. One of the most effective optimizations available today is deploying Atoti, ActiveViam’s in-memory analytics platform, on AWS Graviton, Amazon’s ARM-based processor.
Why Graviton works so well with Atoti
Atoti is built on a Java runtime, making it architecture-agnostic and enabling it to run on Graviton instances with no code changes. This removes typical migration barriers associated with hardware shifts and allows firms to adopt Graviton quickly and safely.
ActiveViam collaborated with AWS to validate Atoti on Graviton, ensuring performance parity with x86-based deployments while delivering substantial improvements in cost efficiency. Customers with large Atoti deployments have already recorded substantial reductions in hardware spend after moving to Graviton-backed instances. One Tier‑1 bank running more than 100 Atoti instances saw approximately a 40% reduction in cloud hardware costs following its migration.
Nomura’s Graviton deployment: Measurable, immediate impact
Nomura’s Market and Credit Risk Technology teams manage highly granular, compute-heavy analytics across large historical datasets. To increase access to historical data while reducing compute expenditure, Nomura migrated its Atoti workloads from in‑house data centers to AWS and deployed them on Graviton using the same memory footprint.
The transition required no refactoring or modification to application code, accelerating their cloud optimization program and avoiding the risk and complexity normally associated with major infrastructure changes. After the migration, Nomura achieved a 42% reduction in compute costs with no degradation in performance or user experience. Analysts retained fast access to both real-time and historical aggregation capabilities across market and credit risk use cases.
"By embracing the power of Atoti on AWS Graviton… Nomura has achieved an unparalleled granular aggregation capability at a drastically reduced cost."
