This session will explain the complexities of the different agent hosting options (Hosted Agents, Private Agents and Environment Agents) and when and how to deploy them. Based on extensive project experience, we will present best practices for agent deployment and setting up the build infrastructure and its configurations, emphasizing the critical interplay of security measures and agent setup. We will also compare the use of pipeline jobs with running agents in containers and provide insights to improve the robustness and efficiency of your CI/CD processes.
