Worked on the pagopa/io-auth-n-identity-domain repository to enhance capacity and reliability for serverless functions in a cloud environment. Focused on infrastructure as code using Terraform and HCL, the developer scaled the io-fn-lv SKU from xl to xxl, increasing performance and supporting higher workloads. Additionally, they raised the minimum number of running ioweb instances from three to four, improving service availability and reliability for production shared resources. All changes were implemented through production-ready Terraform configurations, ensuring safer deployments and better traceability. No bugs were reported during this period, reflecting a focus on proactive infrastructure improvements rather than reactive maintenance.
