Exam MB-400 topic 1 question 1 discussion

So we know the first one is not Azure service bus because they ask for synchronous.Service Bus is only asynchronous. 1.Webhook is the most obvious. https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/use-webhooks#create-or-configure-a-service-to-consume-webhook-requests Next I would say 2.Azure Service bus Azure Service Bus works for high scale processing, and provides a full queueing mechanism if Common Data Service is pushing many events. Webhooks can only scale to the point at which your hosted web service can handle the messages. Last one is Azure Event Hub They want a hybrid. Streaming and event-based solutions are supported, for both on-premises and Azure cloud processing. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-about https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/plug-ins

What is the correct answer guys, there is a lot of speculation in this discussion!

1.webhook, 2.servicebus and 3.plug-in

1. Webhook, this definitely seems to be the answer as the company is looking to build the app to have keyword synchronous calls which the Azure Service Bus is incapable of handling. 2. Azure Event Hub, since the specifications said "high peak load", I would assume it would mean that there would be a lot of entries and data being ingested, and one of the key features of the event hubs are that they would be able to ingest millions of events relatively quickly. 3. Plugins, I know the Azure Event Hub seems tempting, but given some overview it does not look to directly address giving notifications of changes within the app. Looking at plug-ins however, Plug-Ins have many oppurtunities through power automate as well as Service Busses and Webhooks to fully take advantage of notifying of "address" changes. IMO, it might even be more straightforward to use plug-ins.

Webhook Azure service bus plugin

Can some post correct answers ?

2. Service Bus : the target systems have high peak loads. With the messages posted in a queue of the service bus, they will be able to pick up messages intended for them whenever they have free capacity. 3. Event hub - where a message can be passed on to several recipient

3 Needs to Be Azure Event Hubs. Plugins have a 2-minute execution window, and will not be the right solution for N system calls outside of the platform

The second one i feel azure service bus is the better answer because it goes about "calls" so not events. The third one i feel azure event hub is a better solution then a plugin. Azure Event hub also works on prem source: https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-about. "streaming and event-based solutions are supported, for both on-premises and Azure cloud processing." Don't have alot experience with azure event hub, but i would think you still use a plugin to create the azure event hub message when the value is changed but you use the Azure Event Hub to distribute it to all the parties i feel thats whats the question is where do you distribute it, would be alot of a hassle to do this all in the plugin itself.

Azure Service Bus is the correct answer https://www.serverless360.com/blog/azure-event-hubs-vs-service-bus#:~:text=Azure%20Event%20Hubs%20focuses%20more,should%20use%20Azure%20Service%20Bus.

the second answer is "Azure event hub"

https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/use-webhooks Webhooks enables synchronous and asynchronous steps. Azure Service Bus only allows for asynchronous steps. so this must be webhook, I will go with webhook.

I would agree, the second section should be Azure Service Bus

On https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/use-webhooks, it was mentioned that: "Azure Service Bus works for high scale processing, and provides a full queueing mechanism if Common Data Service is pushing many events." Should not the second one is "Azure Service Bus" instead?
