I have a .net core 3.1 web application that reads a variable from the AWS secret manager. I successfully make the call to the secret manager from within one of the controllers. But I'd instead like to make this call once during startup, and have this value available within my application to consume (rather than making the AWS secret manager call every time the controller is hit).
What is the best approach to use here? Should I use caching?

I have a .NET Core 3 Web API that has some external dependencies like Azure SignalR and Azure CosmosDb. I have create a Monitoring Controller which I want to check if the service is healthy by for example pinging those two dependencies.
I haven't found any documentation about how to do this. I know that for example, for Table Storage I can call a method "If table exists" so if it returns true, I know the service can communicate with that dependency.
There is a way to call those dependencies?
PS: I don't want to use 3rd party packages to perform this, I want to know if those services provide this kind of methods.

If you'd like to achieve same for Azure SignalR and Azure CosmosDb, you can try:
1) To check Azure SignalR service, can use management API to get details of Azure SignalR service.
2) To check Azure CosmosDb, can use this API to check if the database you want is existing.
I am trying to test run a basic .NET web application on pivotal cloud foundry. This web application uses as its database a MongoDB server hosted on my local machine. At the moment I am limited to use of the cloud infrastructure by using just the Apps Manager.
I have read the pivotal cloud foundry docs about user provided services, but cannot figure out as to how the connection is to be really made. I have already come across various other ways like using MongoDB as a service (beta version), but at the moment I am not allowed access to the Operations Manager. Looking for an explanation on user provided services or how to implement the service broker API, specifically.
I am new to Mongo as well, so any suggestion regarding making a connection through tweaking Mongo may help as well. Thanks
The use case you describe (web app in PCF connecting to a resource in your local machine) is not recommended.
You can create a MongoDB instance for development purposes in PCF.
$ cf marketplace
...
mlab sandbox Fully managed MongoDB-as-a-Service
...
You can create a mlab service and bind it to your application. You will then have a MongoDB instance in PCF that you can use for development purposes.
Edit:
In that case a user provided service might help you, where you pass in your remote MongoDB instance configuration that you can read in your application. e.g.:
cf.exe cups my-mongodb -p '{"key1":"value1","key2":"value2"}'
You can add your local mongo-db as a CUPS service to your PCF Dev.

I am having trouble wrapping my head around whether or not my scenario will require scale out. I have a process in a windows service that pushes messages to a hub hosted in a web app via the signalr .net client. These are user specific messages and are distributed using the Client(connectionid) approach. If this is deployed in a web farm scenario will I need to use a scale out approach? When a user joins I am storing that connection info in the database. I store the url of the webserver and connectionid so I can target that when I publish messages from the windows service.
I would use this if it is an option.

I have c# console application which is using for some long running task. In my local system I am executing it from ASP.Net MVC 5 controller by System.Diagnostics.Process class. Now we are going it to implement it into azure as our site is deployed in azure in development mode.
I am new to azure so don't how to do it.However study several article I have found that I can upload my console application as web jobs. I can run web jobs as trigger i.e. ondemand.
But now my question is how can execute this web job from MVC controller as I need to pass some argument from controller?
Currently there is no direct link between WebSite and WebJob, even though they are executed in the same application pool. And the best way would be to post a message to a queue from you MVC app. And on the other end have your WebJob to check for the queue for new messages. Just like Andres already said.
This will not be instant, but easy to implement and cheap.
If you need instant reaction from your console app, you'll need to implement your background tasks as Worker Roles and deploy as a separate VMs, and have there some sort of network communication going on, so you can always reach out for your worker role via TCP.
You can set up your web site to push an item to an Azure Queue, and then have your web job be triggered every time an item is pushed to the queue.
There is some information, including code samples for how to do that on http://www.asp.net/aspnet/overview/developing-apps-with-windows-azure/getting-started-with-windows-azure-webjobs.
I am planning a 3-tiered architecture in which I need to track changes to domain objects on the client (a Windows Store app) then send those changes back to the server (an Azure worker-role). I just found out about WCF Data Services which I can run on the client and integrate with Entity Framework Code First on the server. It looks okay but I'm wondering what other tools may also be available.
Are there any alternatives to WCF Data Services for tracking changes in client then sending them to server? If available, I'd like a solution that doesn't require generated DTO classes but instead sends the deltas alone.
Have you considered using rest services?
Im not an AZURE user, but use elsewhere.
