Journey to Adopt Cloud-Native Architecture Series: #3 – Improved Resilience and Standardized Observability

AWS Disaster Recovery

In this blog, we talk about architecture patterns to improve system resiliency, why observability matters, and how to build a holistic observability solution. Minimum business continuity for failover. This allows us to adjust capacity needs by forecasting usage patterns along with configurable warm-up time for application bootstrap.
