**Come join us and tune in to hear Bob Smart present on "Behind the Front Door: Building Secure, Resilient & Recoverable Middleware on Azure"**

A recent redesign of middleware for a financial services mobile app, serving over half a million active users, demanded constant trade-offs between security, performance, resilience, and recoverability. These dimensions often pull in different directions: zone-aware routing and sticky transactions are preferred for financial processing, while mTLS and fixed egress IPs for allowlisting can clash with native Azure resilience patterns.
The architecture incorporated proactive design for recoverability, including routine failover and disaster recovery testing. Azure Chaos Studio played a central role in validating failover mechanisms and observability controls, enabling automated, repeatable testing aligned with APRA’s CPS 230 expectations.
When the system was tested under real-world pressure, including April’s credential stuffing campaigns, heightened media coverage, and market volatility triggered by "Trump’s Liberation Day", the middleware held strong.
