Performance Efficiency: Opt for serverless architectures, explore multi-region deployments, delegate tasks to cloud vendors, and experiment with virtual resources

Performance efficiency is the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve. Evaluating the performance efficiency of your architecture includes experimenting more often, using serverless architectures, and designing systems to be able to go global in minutes.

Answer is A

B. Scaling horizontally Scaling horizontally involves adding more instances or resources to handle increased load, which can help maintain or improve performance efficiency. This principle is part of optimizing performance by adjusting capacity dynamically to meet changing demands.
