Resilient Banking Systems: Applying SRE, Cloud Automation, and Observability at Scale

Abstract

Resilient Banking Systems: Applying SRE, Cloud Automation, and

Observability at Scale

Objectives:
1. Understand the core principles of cloud-native architecture and their role in building scalable
and resilient banking systems.
2. Explore how Site Reliability Engineering (SRE) enhances reliability, availability, and
operational excellence in financial platforms.
3. Learn how cloud automation and Infrastructure as Code (IaC) improve efficiency,
consistency, and disaster recovery.
4. Examine observability practices that enable proactive monitoring, faster incident resolution,
and performance optimization.

5. Analyze integrated strategies combining SRE, automation, and observability to achieve end-
to-end resilience and compliance in banking systems.
