2022 © GridGain Systems 12 GridGain Enables • Distributed in-memory computing supports running a full simulation within 2-3 hours. • Hybrid deployment capabilities allow provisioning and scaling to the cloud • Execution of AI/ML models UPS: Application Acceleration & Scale Out Network Simulation & Planning Challenges • Turn-around time to execute a simulation must be low enough to process 100Ks of simulations • Data generation & simulation execution takes more than a day • Scaling is expensive and time consuming UPS is a global package delivery and supply chain management solutions company. Its services include package deliveries with strict deliver-by SLAs. To consistently meet these SLAs and account for any kind of localized outage in a hub or a processing center, they need viable alternate shipping routes readily available. They achieve this by running simulations and building alternate “network plans” for the next 180-day window.

2022 © GridGain Systems 13 Optiva: Application Acceleration & Scale Out Call Data Records Management & Charging Engine Challenges • Ensure no revenue loss for carriers by guaranteeing exactly once processing of call data records in real time • Zero downtime, fault tolerance • Single architecture that scales based on the carrier size and their subscriber base. GridGain Enables • ANSI SQL and ACID support with strict consistency • Transactional Persistence for disk-based durability and very low recovery SLAs • Horizontal scalability to support small and big carriers with the same solution architecture • Hybrid deployment capability to support on premise or cloud-based deployments Optiva provides business (BSS) and operations (OSS) technology to the telecommunications industry. One of its applications, Optiva Charging Engine, helps telco carriers charge their customers accurately for phone calls and data usage. Processing call data records exactly once, reliably and with ultra low latency is key to win business from carriers. They needed a reliable data management platform that would support small and large carriers alike.
