2025-09 monthly summary for companieshouse/ch.gov.uk focusing on stabilizing and improving the live environment and search capabilities. Delivered provisioning and configuration changes to boost search performance, enable proactive monitoring, and eliminate configuration drift between environments.

In August 2025, delivered infrastructure and configuration changes for companieshouse/ch.gov.uk to improve reliability, traffic routing, and cost control across multiple environments. Implemented environment-wide listener enablement, explicit ECS capacity management, granular health checks, and code readability improvements in Terraform. These changes reduced deployment risk, stabilized service behavior, and demonstrated strong execution of IaC practices.

July 2025 monthly summary focusing on delivering infrastructure improvements for ch.gov.uk to enable safer deployments and scalable resource usage. Delivered environment-level dedicated ECS clusters for staging and live, with flags to control cluster usage and Fargate deployment for services. This work improves workload isolation, deployment reliability, and capacity planning across environments. Commits driving the changes: a6e0add858c7d57efae36b0ea55aac6383d1bc11; 4de4ee32e1971d04c8d78914b6abdff2f0807da8. No major bugs fixed this month; focus was on infrastructure optimization and reliability enhancements.

June 2025 monthly summary for repository companieshouse/ch.gov.uk. Delivered scalable ECS deployment scaffolding with per-service and dedicated clusters (Officers, Search, Default), including data sources, locals, vars, and cluster modules to enable service isolation and targeted resource management. Implemented per-profile dedicated ECS usage with updated locals and data lookups for EC2 instance types, enabling per-profile deployment hygiene and flexibility. Extended live environment support with toggles and live cluster creation in Live and Staging, and added per-cluster service secrets to improve security posture and separation of concerns. Refined deployment defaults and tuning across staging and live (disable Fargate, CPU/Memory tuning) and updated deployment configurations to reflect new infrastructure. Improved reliability and performance with robust local conditionals, ensuring EC2 CPU/Mem usage when not on Fargate and corrected boolean handling, alongside lowering CPU scaling threshold to 15% for more responsive scaling. Completed module version upgrades to align with ECS deployment changes, and enhanced code quality and maintainability via vault key standardization, comments for clarity, removal of obsolete vars, and documentation improvements. Overall, these efforts deliver faster, safer, and more scalable deployments with clearer governance and better operational efficiency in production-like environments.

May 2025 monthly summary for companieshouse/ch.gov.uk focused on reliability, performance, and environment parity. Key features delivered: ECS autoscaling optimization across live, staging, and cidev environments, and re-enabled listeners in CI/CD development and staging to restore event-driven processing. Major bugs fixed: no explicit bug fixes reported this month; efforts concentrated on stability and resource efficiency. Overall impact: improved scalability and responsiveness under varying load, reduced risk of scaling oscillations, and cost efficiency through tuned resources. Technologies/skills demonstrated: AWS ECS autoscaling, CPU/memory balancing, scale-out cooldown management, per-environment task counts, CI/CD flag management, and event-driven architecture across multi-environment deployments.

April 2025 monthly summary for repository companieshouse/ch.gov.uk. Delivered targeted infrastructure and traffic control improvements to enhance resource governance, deployment safety, and service isolation. Implemented granular ECS service configuration with per-service CPU/memory allocations and per-service task environments for selected services, and hardened traffic routing controls by disabling live listener rules to stop cross-service traffic.

March 2025 highlights: delivered targeted ALB routing fixes across PSC, ACSP, and Limited Partnerships APIs; advanced listener system and infrastructure improvements in ch.gov.uk; and introduced dashboards, staging support, and resource management to improve stability and observability. The work reduces routing misclassifications, stabilizes deployments under load, and enables faster, safer feature delivery across services.
