Hello @KK1969 ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you are planning to have an external portal site hosted in Azure and are expecting around 50,000 requests per day to the portal from different countries and would like to know what the recommended type of load balancer in this case is.
Is it Azure Application Gateway V2 with WAF supports the load of 50,000 requests per day from all over the world?
I would recommend you go through the below article where you have a Decision tree for load balancing in Azure and you can determine which load balancing solution is better for your setup:
If your requirement is an Internet facing HTTP(S) traffic load balancer, then yes you can go with Azure Application gateway. It doesn't have any limit on the connections or load and can handle a load of 50K requests per day from all over the world. There is only a limit on the number of Concurrent WebSocket connections.
For more information on Application gateway, refer the below FAQ:
https://learn.microsoft.com/en-us/azure/application-gateway/application-gateway-faq
What are the limits on Azure Application Gateway?
You can refer the below doc which lists the Application gateway limits.
For the internal tiers communication/sharing the load (web tier to app tier), we are thinking to have Azure Load Balancer - Standard type. I have read that it charges based on number of rules at load balancer. But please clarify whether Standard Azure Load Balancer also have any limits on serving the number of web requests per day? Please clarify.
Yes, Load balancer charges based on the number of rules.
Refer: https://azure.microsoft.com/en-in/pricing/details/load-balancer/
You can find the limits on Azure Standard load balancer in the below doc:
Load Balancer doesn't apply any throughput limits. However, throughput limits for virtual machines and virtual networks still apply. For more information, see Virtual machine network bandwidth.
