July 2026 (2026-07) monthly summary focusing on key accomplishments: Delivered two major reliability improvements in the cloud-platform-environments workstream. (1) DLQ monitoring and alerting for lao_domain_events_dlq across preproduction and production environments, with CloudWatch alarms and Prometheus rules to flag messages lingering in the DLQ beyond 15 minutes, enabling proactive incident response. (2) DLQ automatic redrive from the Dead Letter Queue to the main queue via a Kubernetes CronJob in the hmpps-probation-mi-ui-test namespace, scheduled daily at 09:00 UTC, using AWS CLI and environment-specific queue ARNs to improve recoverability. These efforts consolidate DLQ monitoring into a single coherent feature set and directly enhance reliability, observability, and recovery capabilities. No major bug fixes were logged this month. Key benefits include faster detection of stuck messages, automated recovery, and reduced manual intervention across preprod/prod/test environments.

June 2026 performance summary focusing on delivering scalable, observable, and maintainable cloud environments. Key outcomes include baseline infrastructure and CI/CD for cloud-platform-environments, enhanced observability with pre-computed latency quantiles, consolidation and stabilization of probation user creation in Redshift, and traceable changes across environments.

April 2026 focused on delivering automation for cloud deployments and strengthening observability for critical services in the cloud-platform environments. The work delivered a new deployment pipeline trigger, enabling faster, safer releases, and fixed Prometheus monitoring for hmpps-digital-prison-reporting-mi-ui to ensure accurate metrics across all environments. These changes reduce deployment toil, accelerate issue detection, and demonstrate strong DevOps capabilities.

March 2026 delivered core development infrastructure for the HMPPS Probation UI in cloud-platform-environments, enabling isolated dev environments and secure, scalable deployments. Implemented a new Kubernetes namespace with RBAC and infra controls (LimitRanges, ResourceQuotas, NetworkPolicies) and cross-account IAM roles to support UI development. Introduced HAAR client admin RBAC to empower the team to manage deployments, secrets, pods, certificates, services, ingresses, configmaps, and events within the probation microservice environment. Extended certificate configuration with a DNS name to support the service domain. Upgraded infrastructure modules to take advantage of latest features and fixes: Elasticache cluster to 8.1.0 and cloud-platform-terraform-serviceaccount to 1.2.0. Overall, these changes improve dev speed, security, and reliability, enabling safer multi-team collaboration and smoother deployments. No major bugs reported this month; improvements reduce operational toil and set a stronger foundation for future platform iterations. Technologies demonstrated include Kubernetes ops (namespaces, RBAC, policies), cross-account IAM, DNS/certificate management, and Terraform module upgrades.

February 2026 monthly summary for ministryofjustice/modernisation-platform-environments. Key features delivered: infrastructure cleanup and cost optimization; AWS Glue connection module for Redshift data domain. Major bugs fixed: none reported this month. Overall impact and accomplishments: reduced cloud spend by removing unused resources, simplified infrastructure, improved data connectivity to Redshift, and strengthened security posture through explicit connection properties and security configuration. Technologies/skills demonstrated: Terraform, AWS Glue, AWS Kinesis, EventBridge, Redshift connectivity, security configuration, and IaC best practices for cost governance.

January 2026: Delivered the Digital Prison Alert Slack Channel Naming Convention for the ministryofjustice/modernisation-platform-environments repo, standardizing Slack alert channel names to improve clarity, incident triage, and response times. The change reduces cognitive load for operators and supports faster incident handling through consistent naming across DPR alert channels.

November 2025 monthly summary focused on delivering observability enhancements and governance improvements for the data platform environments. The work prioritized business value through improved resource visibility, faster diagnosis, and better governance.

Month 2025-10 monthly summary for ministryofjustice/modernisation-platform-environments focusing on key business outcomes and technical achievements. Key features delivered: - Terraform Tagging and Naming Standardization Across AWS Resources: Standardized tag keys and resource naming across Terraform-managed resources to improve governance, consistency across environments, and reduce churn from unnecessary updates. Included refactoring work and naming alignment for instances and data files, with safeguards (ignore-tags) to minimize disruption. - RDS and Secrets Manager Lifecycle Stabilization: Implemented lifecycle rules to ignore changes where safe, stabilizing RDS and Secrets Manager configurations and reducing unnecessary resource replacements while strengthening secret management. - Platform Update: Windows AMI for Digital Prison Reporting System: Updated Windows AMI to the latest version to improve performance, security, and compatibility for the reporting platform. Major bugs fixed: - Resolved RDS-related instability by applying lifecycle ignore-change rules and targeted fixes, reducing unexpected replacements and one-off outages. - Minor configuration inconsistencies addressed (e.g., platform file adjustments and ignore-tags handling) to ensure tagging governance remains non-disruptive. Overall impact and accomplishments: - Improved governance and operational efficiency through consistent tagging and naming across environments, reducing drift and update churn. - Increased platform stability and reliability for RDS and Secrets Manager, resulting in fewer upgrade-induced disruptions and smoother secret management. - Enhanced security posture and performance for the Digital Prison Reporting System via an updated Windows AMI. Technologies/skills demonstrated: - Terraform and AWS resource management (RDS, Secrets Manager, EC2) with lifecycle rules and tagging conventions. - Infrastructure as Code refactoring, naming standardization, and governance automation. - Change management with careful rollouts to minimize environment disruption and ensure safe updates.

September 2025 monthly summary for ministryofjustice/modernisation-platform-environments: Highlights include key feature delivery, major fixes, and business impact in the digital-prison-reporting environment. Key features delivered: - DPR Resource Tagging Standardization: Standardizes tag keys to a 'dpr-' prefix across AWS resources (Glue jobs, S3 buckets, DynamoDB tables) to improve consistency and governance of resource metadata. - (No other new features were delivered beyond tagging standardization in this period.) Major bugs fixed: - Windows Compute Node: CKV_AWS_79 bypass due to IMDSv1 compatibility. Implemented a controlled bypass with checkov:skip directives and documented justification to support legacy systems while maintaining governance. - Compute Node Windows Terraform Typing and Version/Provider Constraints: Addressed Terraform typing issues and enforced version/provider constraints for the compute_node_windows module, including explicit type definitions and updates to Terraform version/provider requirements. - Commit activity included multiple Chekov-related fixes to stabilize the module. Overall impact and accomplishments: - Improved metadata governance and cost allocation accuracy through consistent tagging across core compute and data resources. - Enhanced reliability and compatibility of Windows compute node provisioning by aligning typing and provider constraints and by documenting secure bypasses where needed. - Reduced risk of drift and improved security-scanning compatibility (Chekov) across the Windows compute node module. Technologies/skills demonstrated: - Terraform module hardening (typing, version/provider constraints). - Checkov policy management and justified exceptions (CKV_AWS_79). - Resource tagging governance and metadata standardization. - Code review discipline, tracking changes via commit messages and references. Business value: - Improved resource visibility, cost attribution, and compliance reporting for the digital-prison-reporting environment; smoother audits and fewer tagging ambiguities; more robust and maintainable infrastructure code across Windows compute node provisioning.
