When you have 200 concurrent users hitting a single-threaded service, you’ll see the connection pool exhaustion error: “java.sql.SQLException: Unable to acquire JDBC Connection”. This is because the default connection pool size is not sufficient for production workloads. To avoid this, you need to implement Terraform best practices for production infrastructure. TL;DR: In this tutorial, you…

IaC allows developers to manage and provision infrastructure through code, rather than manual processes. This approach enables version control, reuse, and automation of infrastructure configurations. To get started with IaC, developers should have…
