Case Study: Avanza Bank achieves real-time, in-memory performance and 6× faster time-to-market with GigaSpaces

Avanza Bank - Customer Case Study

Avanza Bank, Sweden’s largest stockbroker and a customer‑centric digital bank, faced major scalability, latency and availability problems from its legacy three‑layer architecture (web, business logic, SQL). Critical batch jobs degraded over time—for example, a daily customer benefits job grew from 6 hours in 2010 to 18 hours by 2014—hindering performance and growth.

Avanza replaced its relational backend with Smart DIH as a single source of truth, holding over 22 TB in memory and enabling a microservices-driven platform. The change cut the benefits job to 10 minutes, raised availability to 99.999%, boosted microservices from ~150 to 1,200+, achieved 1.7 ms mean response times, delivered 6x faster time‑to‑market (simple services to production within a day), and enabled real‑time features like trade recommendations and 2‑minute loan approvals.
