Multi-Cloud performance benefits
To the left is an example analysis we do for interested customers using actual Radar data, which shows expected performance gains from load balancing across multiple clouds. Importantly, note that the different colors display the relative performance of different traffic routing methodologies: Round Robin, Historical Latency data and Real Time Latency data.
Round robin routing is fine for improving availability by maintaining active-active instances, but does little to improve performance. Latency routing using historical data results in limited benefit, as is seen by users of the daily latency data used by AWS-Route 53. Significant gains are found when using real-time data, however, providing meaningful latency reduction for your end users.
