Something of interest
The Open Banking – UK – Production Fintech API metrics category is a big category. But let’s look at the Top Ten, but by outliers, not by CASC score. 
Now, what’s interesting is that the top three Fintech APIs by outliers are also the top three Fintech APIs by CASC score. You want to have a consistent service because that’s what your users want and you don’t want to have many outliers because they will affect user experience negatively, for instance, causing apps to time out. Tide takes the Fintech API title this week, but a photo finish as less 0.01 of a CASC score point separates it from Danske Bank. Both Tide and Danske Bank have a very low percentage of outliers at 0.30% and 0.37% and Tide (Auth) comes in third on both CASC score and outliers with an outlier percentage of 0.55%. We then see a leap to 1.05% outliers for fourth place for OBIE Directory (Production Auth), so it is noteworthy that only Tide and Danske Bank have been able to keep the outlier percentage below 1% this week. This shows how hard it is to do that and why it is vital to actively monitor from APIs so that you know exactly how your APIs are behaving. 
Both Tide and Danske Bank have pretty consistent median latencies across the different clouds. Tide has a variation of 38 ms and Danske Bank 40 ms. This implies a pretty low standard deviation and this will help get your Fintech API CASC score up. You don’t which cloud your users are going to be invoking you from and you want to make that they get the same high quality service wherever it is. 
As we can see from Clydesdale Bank, which is tenth in terms of outliers, its variation in Total Time is rather great than for Tide and Danske Bank at 65 ms. It’s by monitoring these metrics and working to optimize your architecture and network configuration that you can deliver the best possible service to your users.
