Led the automation of a large-scale infrastructure deployment using Ansible, optimizing the process with advanced techniques like forks, serial execution, and delegation. By leveraging forks, I accelerated the execution of tasks in parallel, significantly reducing deployment time across hundreds of servers. Serial execution was employed to carefully roll out updates in controlled batches, ensuring service availability and minimizing downtime. Delegation to specific hosts allowed offloading complex tasks to specialized nodes, enhancing system efficiency.
