Aurkibidea:
- <p>As enterprises increasingly migrate mission-critical applications to the cloud, achieving continuous availability</p> <p>across geographically distributed regions becomes essential for meeting service-level objectives and ensuring</p> <p>operational resilience. This paper presents high availability (HA) strategies for cloud-based active–active</p> <p>services, emphasizing the use of core infrastructure primitives such as global DNS load balancing, regionspecific load balancers, and smart health checks. Through a comparative analysis of leading cloud platforms—</p> <p>Google Cloud Platform (GCP), Microsoft Azure, and Amazon Web Services (AWS)—the paper outlines</p> <p>methodologies for designing robust, multi-region architectures capable of sustaining sub-second failover and</p> <p>seamless user experiences. It further explores the role of DNS-based routing, L4/L7 load balancing, CDN</p> <p>integration, and real-time observability tools in enabling automated recovery from regional and service-level</p> <p>failures. In addition to platform-specific evaluations, the paper provides actionable best practices for deploying</p> <p>HA systems, including low-TTL DNS configurations, comprehensive dependency-aware health checks, and fault</p> <p>injection testing. The paper concludes by reinforcing the importance of layered failover mechanisms and</p> <p>continuous monitoring in achieving operational excellence in modern cloud-native environments</p> <p>This record contains metadata only.
