Hello @Asif Shafeeque ,

In terms of handling millions of requests, an API Gateway, like a load balancer, is designed to handle high volumes of incoming HTTP/HTTPS requests.

To prevent single point of failure, you can use a combination of availability zones and multi-region deployments.

API Management provides an SLA of 99.99% when you deploy at least one unit in two or more availability zones or regions.
