June 2026 monthly summary for alphagov/govuk-infrastructure focusing on business value and technical achievements. Key features delivered include enabling encryption at rest in the OpenSearch cluster by adding a Terraform variable block (encryption_at_rest), addressing Terraform undeclared-variable warnings and enabling dynamic encryption configurations. Major bugs fixed include mitigating Disk Throughput Throttle warnings during search-index-env-sync by increasing provisioned throughput: EBS volumes (250 MBps -> 300 MBps) and Elasticsearch environments (300 MBps -> 350 MBps) across integration, staging, and production, followed by a further +50 MBps adjustment to further reduce throttling. This work is backed by commits 3ea61194fb1270b16d323b01e4dd25446d54bb5b and ddf6e632b2851ecea92c4f34e989709b5eeb8894. The changes reduced throttling incidents and improved indexing reliability in production-like environments. Overall impact includes stronger reliability for search-index-env-sync workflows, improved security posture with encryption at rest, and clearer IaC definitions. Technologies/skills demonstrated include Terraform, OpenSearch configuration, AWS EBS provisioning, and performance-tuning of infrastructure as code.
