Zero-Downtime Blue-Green Deployment Pipelines for Python Applications on AWS

Establishing the Blue-Green Foundation with AWS Elastic Beanstalk Blue-green deployment is a strategy that minimizes downtime and risk by running two identical production environments, “Blue” and “Green.” At any given time, one environment (e.g., Blue) is live and serving production traffic, while the other (Green) is idle. To deploy a new version, we deploy it […]

Zero-Downtime Blue-Green Deployment Pipelines for Python Applications on DigitalOcean

Understanding Blue-Green Deployments Blue-Green deployment is a strategy for reducing downtime and risk associated with application releases. It involves maintaining two identical production environments, “Blue” and “Green.” At any given time, one environment (e.g., Blue) is live and serving production traffic, while the other (Green) is idle. To deploy a new version, we update the […]

Resolving indexing lock conflicts and high CPU during bulk stock updates Under Peak Event Traffic on AWS

Diagnosing the Root Cause: High CPU and Lock Contention During peak traffic events, especially when coupled with high-volume stock updates, systems often exhibit a dual symptom: elevated CPU utilization and persistent database lock contention. This is not a coincidence; these issues are frequently intertwined. The high CPU is often a direct consequence of the database […]
