GitHub Copilot Customization Explained for Beginners: Instructions, Prompt Files, Skills, Agents, and Hooks Introduction If you've recently started using GitHub Copilot, you've probably come across terms like Instructions , Prompt Files , Skills , Agents , and Hooks . At first glance, they all seem to do the same thing—they tell Copilot what to do. So why does GitHub have five different customization features? The answer is simple: each feature solves a different problem. Think of GitHub Copilot as a new developer joining your team. On their first day, you don't just hand them code. You explain your coding standards, give them reusable templates, teach them specialized knowledge, assign them a role, and automate repetitive tasks. That's exactly how GitHub Copilot customization works. In this article, you'll learn what each feature does, when to use it, and how they all work together. By the end, you'll know which feature to start with and which ones can wait un...
Azure Front Door - Boost Your Web Application
If you are developing a new or an existing web application that is internet facing and can be accessed globally or deploying the new or existing web application in multiple regions then it's high time to consider Azure Front Door in your application architecture.
Azure Front Door Service (AFD) a scalable and secure entry point for the fast delivery of your global applications. Azure Front Door allows you to transform your global (multi-region) applications into robust, high-performance applications, APIs. AFD makes use of Microsoft Global Network which provides better network performance and reliability. Azure Front Door is a global service and is not tied to any specific Azure region. Azure Front Door is a globally distributed multi-tenant service. The infrastructure for Front Door is shared across all its customers.

| Reference Architecture with AFD Image Source: Microsoft |
Benefits of using Azure Front Door:
- Accelerate application performance, AFD significantly increases application network performance by reducing the round trip time that the end-user spends on the network while trying to access the application. Also AFD route users to the most performant application. In short, it supports multi-geo redundancy and closest region routing.
- TLS termination at the edge (AFD) saves application backend from encryption and decryption.
- Session affinity to handle sticky sessions
- Redirect traffic to your application based on the region it's been accessed
- AFD makes application resilient, by providing automatic failover by monitoring application in terms of latency and availability using health probes
- AFD supports URL-based routing which is an added advantage for Microservice architecture.
- AFD provides integration with WAF to define custom rules and to provide security from DDoS attacks.
- Rewrite URLs capability supported.
- Multiple site hosting, which means you can have 2 different domains configured on the same front door.
You can find all the Azure Front Door locations here: https://docs.microsoft.com/en-us/azure/cdn/cdn-pop-locations
Now if you are thinking about how Azure Front Door is different compared to Azure Traffic Manager, I highly recommend visiting my another blog post (AFD vs ATM) where I have tried to show the similarities and differences between those 2 Azure services.

Tidy up - Unused Project and Nuget package reference using Visual Studio 2019
If you are a Developer/Architect using Visual Studio as IDE for your development activities, this blog post will be of your interest. During the Ignite 2021 conference, Microsoft released Visual Studio 2019 v16.9 and v16.10 Preview 1. As part of version 16.10 Preview 1, one of the cool features they introduced is to "Remove Unused References..." for any Projects and Nuget packages that are not in use. At the time of writing this blog post, we have Visual Studio Version 16.10.0 (official release) which includes this new feature. As part of development, we generally get carried away and introduce new Nuget package references to your project and add new references to your Projects. By the end of development, you will not be 100% sure which are not being referenced and unused which means you will leave those unused project references in your application. Now you might be wondering what's the big deal in it since it doesn't harm. The advantage of removing unused project r...
Azure Front Door vs Azure Traffic Manager?
In my previous blog post, we looked in detail Azure Front Door (AFD) . In this blog post, let's compare Azure Front Door (AFD) with another popular Azure service named Azure Traffic Manager (ATM). Prior to AFD most of the applications made use of ATM in their architecture now with AFD being available it's good to understand in which scenarios these individual services are ideal. Azure Front Door (AFD) Azure Front Door Service (AFD) a scalable and secure entry point for the fast delivery of your global applications. Azure Front Door allows you to transform your global (multi-region) applications into robust, high-performance applications, APIs, and content. Azure Traffic Manager (ATM) Azure Traffic Manager is a DNS-based traffic load balancer for geographically distributed Datacenters. Traffic Manager uses DNS to direct traffic to endpoint based on the traffic routing method and health of the endpoints. Similarities between AFD and ATM Both Azure Services support Multi-...
Authenticate Azure Functions - API Keys
In this blog post, we will see one of the ways to secure your Azure Functions using API keys. Security plays a key role as part of SDLC (Software Development Life Cycle) doesn't matter whether it's exposed to the client/public or even if it's internal. There are multiple ways to secure your Azure Functions like API Keys, Certificate, API Mgmt, App Service Authentication, etc. If you are new to the Cloud and Azure Functions but want to make a start with minimal effort and less setup of Infrastructure, then API Keys is the ideal choice. Azure Functions allows you to secure HTTP-triggered functions by API access key in the request. As part of creating new Azure Functions, we can select the Authorization Level enum value. If we set the Authorisation level to Anonymous, no security applied which means no authentication applied for the endpoint. Authorization Level - Function By setting the Authorisation level to Function each Azure Functions require a specific API key to Au...
