Creating Virtual Environment for Python from VS Code

When we are talking about a term environment along with Python, it is a context in which our Python application runs, or we can say that the Python program runs.   An environment consists of an interpreter and all the installed packages, which clearly means that one can have multiple environments on a single machine, or rather I would say, every Python application can have its own environment. Now the question is, why do we need such environments?   To know more about the virtual environment and how to create one using Visual Studio Code, watch out my recorded video on my YouTube channel named Shweta Lodha.

Chat Application using Azure Web PubSub Service (Preview)

Azure Web PubSub service, as its name says, it is based on publish-subscribe pattern and enables us to build real-time web applications.  Some of the popular examples where we can use this service is, for any chat-based applications, any collaboration application, like white boarding application. We can also use this service for any application which needs instant push notifications. In fact, there are many more example, we can think about.  The best part is, we can use Azure Web PubSub service on all the platforms which supports WebSocket APIs and it allows up to 100 thousand concurrent connections at any point of time. Components required to create a basic chat application: Instance of Azure Web PubSub Service Publisher application Subscriber application To know about how to create and use these components, I’ve created a complete video demonstrating these on my YouTube channel named Shweta Lodha. C# Code for Publisher and Subscriber: Below is the C# code for the r...

Redirecting Traffic Based On Priority Using Azure Traffic Manager

For any web application to work there has to be an associated end point, which means whenever users sends a request, endpoint is the first thing which gets hit. If I say in simple term, endpoint is an internet facing service which could be hosted either in Microsoft Azure or outside of Azure. What is Azure Traffic Manager Now what is  Traffic Manager ? As it’s name suggests, it manages the traffic. It distributes the traffic across various Azure regions along with health monitoring capabilities. So, if you are planning for a multi-region support with high availability, it could be a perfect service for you.   Now, you must be thinking, what is the core which is making this happen? Actually it uses the DNS to route traffic to endpoints based on the selected Traffic Manger profile  and the configured routing mechanisms. I’ll shortly mention about what all routing methods are available but before that let’s take a quick look at some of the major benefits which we can achie...

Enabling Preview Features in Visual Studio 2019

By default, Visual Studio doesn’t enable preview feature selection in Visual Studio 2019 . Say you have .Net 5.0 installed on your machine and you are creating a new Console Application.   After creating the application, you will notice that, although .Net 5.0 is installed, application still picks up the .Net Core 3.1 as a default framework. In fact, application didn’t ask for framework selection too. So, how can we select the framework while creating an application itself. For doing this, we need to enable Preview Features in Visual Studio by going to Options menu as shown below:

Get Notified via Azure Event Grid whenever Azure Blob is updated

In this article, we will learn how to get notification whenever something is changed in Azure Storage . Let’s say, we want our application to get notified whenever any new file is uploaded to the blob or say any file is deleted from the blob. How can we do that? Before directly jumping into the solution, let’s have all the major pieces listed here which will contribute towards this. Azure Storage: We need an Azure storage wherein we will be uploading our blog objects, i.e. image files. Azure Event Grid: Next we need is Azure Event Grid. It is a routing service provided by Microsoft and the best part about this service is, it has built-in support for events coming from storage blobs and resource groups. So, we need to create a subscription which will tell what event and which specific topic we are interested in. Endpoint: Lastly, we need an endpoint, which will receive notifications. So, it could be Function App, Logic App, or any custom application which is hosted somewhere a...

Bring Azure Blob Objects Back to Life

Nowadays, there are many applications which are utilizing Azure Blob Storage for reading and writing objects. Looking at that, it’s quite common that these objects may get deleted accidentally due to user’s negligence or application's behavior.  So, my today’s writeup is around this topic wherein we will see, how can we bring back our deleted blob objects back to life. Lifecycle of blob storage is managed by a very well-known concept called Versioning . Versioning deals with the state - when any object was created, when was it modified or when was it deleted. If this topic impresses you, you can read complete blog post at C# Corner website or you can view it on my YouTube channel named Shweta Lodha.

Azure App Registration and Microsoft Graph API

As part of Sip and Learn series, this time I covered a very interesting topic – App registration for Microsoft Graph API in AAD. Here you will get to know how to do application registration using Azure portal and what all permissions need to be given to call particular type of API.
