Content delivery systems are software systems whose main functionality is to deliver streaming content to users such as video and audio. This content is typically stored in large capacity databases and streamed from a server. Because of the vast distances of users $($worldwide$),$ these systems suffer from high delays in the network. Leveraging the performance tactics shown in the figure below and detailed in the Appendix of the Software Architecture Design Process in the lecture notes recommend the most suitable tactic to manage the resources that can mitigate the delays encountered in the delivery of content to users. Note: Your answer should be tailored to a content delivery system. Just don$$t copy and paste the description of the tactic.
