Given the limited information provided, one option would be to create an AccountCreated event, (or an EntityCreated event if this is a cross-cutting concern) and publish it through some bus where consumers can asynchronousle receive it and do any subsequent processing needed.

The event need not use domain entities, and it can contain the information/data necessary to do any subsequent processing without the need to access a shared db (and as such adhering to DDD & microservice guidelines).

----Edit----

In the above I assumed that this is an established system and Azure storage isn't something that can change. Publishing an event, and handling it is pretty simple, but there are some things you need to be aware of. In general, you have 3 options here:

1. Publishing right after saving isn't wrong. It's simple way to do it, and (if you adopt an event-first methodology) you can do it in a generic way across your entities, minimal work. However, you need to be concious of how to deal with errors. Specifically, the issue is that if you store the entity first, before publishing the event, and then the process crashes for whatever reason, the event may be missed, so later workflows will not kick-off. If you do the reverse (publish then store), you run the risk of double-publishing the event. In this case you have two options:

   1. If you store-then-publish: just accept the (really rare) possiblity of not publishing an event. This is something you need to speak to the business, and you can minigate the severity by logging the event before trying to save the entity.
   2. If you publish-then-store: (you'll need to do this if the cost of fixing any issues ad-hoc are too great) you can fix the problem by having your consumers check the id of the incoming message if they ever have processed it before and reject it if they did OR make the process idempotent (if possible), meaning that doing the process twice isn't a problem

2. Using event sourcing. This isn't difficult in my opinion, but obviously it's an overhead if this is a a simple application, and while not difficult, it does need a significant amount of reading up if you're not familiar with it. If this is a non-trivial application, event sourcing can help a lot, because observers can just observe the events in the buffer and respond to that (so not need to explicitly publish the changes).

3. Append the event in a separate table within the same transaction where you're storing the entity, and use the outbox pattern implementation (publish those events from a separate service, marking them as published once they've been published). Honestly, the pattern shown on that is a bit simplistic, and there are a lot of tricky and small complexities, so prefer to use an existing one if you can find.

Honestly, if you can get away with 1.1, do that. It's simple and problems only very rarely appear. Just log the operation before you do it so that you can manually do it in the rare case of issues.

After posting the question, I tried things myself.

As per amazon,

Your Amazon ElastiCache instances are designed to be accessed through an Amazon EC2 instance.

I think you should use @SessionAttributes. To use @SessionAttributes we can store modelAttribute in Session and when there is no use of modelAttribute. We can remove it.

We can remove it like this:

Since the generation of the page is done server-side before it is displayed to the user regarding the ASP side of things (disregarding any AJAX that is triggered and posted to the page that may be called client-side) you can just provide these instructions in the Page Load method.

If you look at the life cycle

You can see that it would be acceptable for your purpose to initialise the control and set properties such as text in the Page Load method for when the page is created. All you need is for runat="server" to be implied and to access the control from the code behind using it's ID. You can then set its innerHTML to whatever you like or it's .Text property or Value.

The assignment will look something like this:

I can't see why you need the separate tOTPModel array. I would delete that and just use the tOTPS array, and I would put the generator in the TOTP object, where it belongs.

Now you can just reload the visible rows each time the timer ticks.

If you want use some special characters, you have to set up a regex for Spring. See this link https://stackoverflow.com/questions/16332092/spring-mvc-pathvariable-with-dot-is-getting-truncated

You're logging the data before it's resolved, change to:

In logSubmit you are missing back slash after authUser:
