June 2026 — Tech-docs (govuk-one-login/tech-docs) monthly summary focused on Spoke VPC architecture experimentation, evaluation, and governance. Implemented initial Spoke VPC template adjustments to switch from Firewall Subnets to Public Subnets to address resource allocation and functionality, followed by a rollback that removed Spoke VPC resources and eliminated Spoke VPC architecture from the deployment pipeline due to architectural reconsiderations. This cycle provided actionable engineering insights, stabilized the deployment pipeline, and informed future networking decisions.
