February 2026 (2026-02) summary for ministryofjustice/modernisation-platform-environments: Delivered non-production environment cloning and deployment automation to improve environment parity and deployment flexibility. Implemented initial clone import workflow and updated Terraform configuration to support cloning a production app into non-production environments. Hardened security for the POC clone by standardizing the security group to ensure proper network access. These changes streamline environment provisioning, reduce manual steps, and strengthen IaC practices with traceable commits.

January 2026: Delivered automation, PoC infrastructure, and cross-environment secrets governance to accelerate deployments, improve security, and strengthen testing. Key features include automated CI/CD build triggers and Concourse pipeline automation, Tariff App server PoC infrastructure enabling testing, and expansive Secrets Manager module upgrades across Copilot, Experian, Review Case Documents, and Claim environments. Also fixed namespace cleanup to ensure clean resource lifecycle and maintained dependencies to latest versions. Result: faster release readiness, standardized secrets handling, reduced manual toil, and improved governance across environments. Technologies demonstrated include AWS EC2 provisioning, security groups, Secrets Manager, CI/CD tooling (Concourse), and IaC practices.

December 2025 monthly summary: Delivered production-grade automation for Tariff App environments by implementing automated AMI creation and production environment cloning, migrating away from the v1 AMI approach. Strengthened AWS SSM maintenance window reliability and governance with environment-scoped provisioning, IAM roles/policies, and scheduling controls to ensure repeatable maintenance. Hardened network security for Tariff App clones with restricted networking and aligned security groups to production, including updated analytics CIDR ranges for development and production environments. Resolved maintenance window defects by correcting date scheduling and instance targeting, and by removing an invalid parameter from the config. Enabled secure on-premises LAN access for CICA users with updated firewall rules to allow traffic between on-prem and MP CICA environments. These initiatives collectively reduce deployment risk, accelerate testing and production readiness, and strengthen security and governance across the platform.

November 2025 delivered security, resilience, and governance improvements across the modernisation platform stack, with concrete business value in safer production releases, scalable storage, and secure cross-environment access. Key features included production-scoped Tariff App security groups with side-by-side deployment to support incremental changes without downtime, and NFS port updates to enable reliable storage access. Major enhancements also covered backups on non-production instances, root volume tagging, and volume sizing adjustments to accommodate growth. Bugs around ingress security group handling and volume tagging were fixed, and infrastructure resource tagging/naming consistency improvements were completed to aid cost governance and operability. Additionally, cross-environment firewall rules extended Analytical Platform access to CICA MP in UAT and Prod, enabling secure data sharing for analysis and reporting. Overall, these efforts reduce risk, improve operational agility, and strengthen security and governance while delivering measurable production readiness improvements.
