Zero-Downtime Blue-Green Deployment Pipelines for Laravel Applications on Google Cloud

Understanding the Blue-Green Deployment Pattern The Blue-Green deployment strategy is a technique for releasing new versions of an application with zero downtime. It involves maintaining two identical production environments, “Blue” and “Green.” At any given time, one environment (e.g., Blue) is live and serving all production traffic, while the other (Green) is idle. To deploy […]

Infrastructure as Code: Provisioning Secure Ruby Clusters on AWS Using Terraform

Terraform Project Structure and Provider Configuration We’ll begin by establishing a robust Terraform project structure. This promotes maintainability and scalability. Our primary focus will be on provisioning a secure Ruby application cluster on AWS. This involves defining VPCs, subnets, security groups, EC2 instances, and load balancers. The core of our infrastructure definition will reside in […]

Step-by-Step: Diagnosing Slow Largest Contentful Paint (LCP) caused by unoptimized database queries on AWS Servers

Identifying Slow LCP Due to Database Bottlenecks Largest Contentful Paint (LCP) is a critical user experience metric. When LCP is slow, especially on AWS-hosted applications, the database is often a prime suspect. This post details a systematic approach to diagnosing and resolving LCP degradation caused by unoptimized database queries, focusing on common AWS infrastructure components. […]
