Zero-Downtime Deployment Strategies In Financial-Grade CI/CD Pipelines: Enabling Continuous Compliance And Resilience

Abstract

The topic of the research presented in this paper is zero-downtime deployment strategies in financial-grade CI/CD pipelines with a focus on resilience and regulations compliance. It presents an empirical evidence and systematic review synthesis to discover practices related to blue-green deployments, canary releases, and automated rollback mechanisms. The aspects of Infrastructure as Code (IaC), service mesh architectures, and compliance-aware DevOps pipelines are explored in how they provide availability and reduce risk. Quantitative details illustrate the trade-offs among reliability, speed and security. Results indicate that zero-downtime methodologies in conjunction with continuous compliance tooling, have a substantial benefit on system availability and regulatory correspondence in high-availability fiscal systems.
