Zero-Downtime Blue-Green Deployment Pipelines for Laravel Applications on OVH

Understanding the Blue-Green Deployment Pattern The blue-green deployment strategy is a technique for releasing software that minimizes downtime and risk. It involves maintaining two identical production environments, referred to as “Blue” and “Green.” At any given time, one environment (e.g., Blue) is serving live production traffic, while the other (e.g., Green) is idle. To deploy […]

Disaster Recovery 101: Architecting Auto-Failovers for Elasticsearch and Perl Deployments on Linode

Elasticsearch Cluster Health and Node Roles Achieving automated failover for Elasticsearch hinges on a robust understanding of its distributed nature and internal health mechanisms. Elasticsearch employs a master-eligible node system to manage cluster state. For high availability, it’s imperative to configure multiple master-eligible nodes. These nodes don’t necessarily need to be dedicated; they can also […]

How to Customize Child Themes and Custom Styling Overrides under Heavy Concurrent Load Conditions

Leveraging Child Themes for Robust Customization When embarking on WordPress theme customization, the cardinal rule is to always use a child theme.
