Building Azure Infrastructure with C#
In this video, I’m going to show you how you can create Azure instances with a simple Console C# app. And then I will walk you through the entire process of productionization to incorporate your provision code in Azure DevOps pipelines so you can allow your entire engineering team to push modifications to Azure without having to learn ARM templates, YAML or using the dashboard.
Here’s a link to the final project:

How to Build and Deploy C# Azure Functions using Multi-Stage Pipelines in Azure DevOps
As part of my personal development, I’ve created a personal health platform that uses various different microservices (Built using Azure Functions) that extract data from my Fitbit account and store them in an Azure Cosmos DB database. I have other microservices that pass messages between different services via Azure Service Bus.
For this project, I use Azure DevOps to build my artifacts, run my unit tests and deploy my microservices to Azure. The great thing about DevOps is that we can do all of this within the YAML pipeline.
Yes I said YAML. Honestly, I don’t know what the fuss is all about 😂
In a previous post, I talked about how we can deploy NuGet packages to a private feed in Azure Artifacts using YAML pipelines. If you haven’t read that post yet, you can check it out below!
In this article, we will turn our attention to building and deploying C## Azure Functions using a single build file.
#What we’ll cover
We’ve got quite a bit to cover, so I’ll break down my YAML file and talk about each stage in the following order:
- Triggering a Build 👷♂️👷♀️
- Using User-Defined Variables in our pipelines 👨🔬👩🔬
- Defining Stages 💻
- Building our project 🔨
- Running our tests 🧪
- Getting code coverage 🧾
- Producing a Build Artifact 🏠
- Using Secrets from Key Vault 🔑
- Deploying our Function to Azure ⚡
- Running our build pipeline 🚀

How to Run C/C++ in Sublime Text?
C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.
In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.
During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. Vim, Sublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.
I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++
If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:
- Using multiple variables in the print function
- Comparing Signed integer with unsigned integer
- Putting a semicolon at the end of the loop statement
- C preprocessor doesn’t need a semicolon
- Size of the string matters
- Macros and equations aren’t good friends
- Never compare Floating data type with double data type
- Arrays have a boundary
- Character constants are different from string literals
- Difference between single(=) and double(==) equal signs.
The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.
- %d indicates Integer Format Specifier
- %f indicates Float Format Specifier
- %c indicates Character Format Specifier
- %s indicates String Format Specifier
- %u indicates Unsigned Integer Format Specifier
- %ld indicates Long Int Format Specifier
A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

Learn NoSQL in Azure: Diving Deeper into Azure Cosmos DB
This article is a part of the series – Learn NoSQL in Azure where we explore Azure Cosmos DB as a part of the non-relational database system used widely for a variety of applications. Azure Cosmos DB is a part of Microsoft’s serverless databases on Azure which is highly scalable and distributed across all locations that run on Azure. It is offered as a platform as a service (PAAS) from Azure and you can develop databases that have a very high throughput and very low latency. Using Azure Cosmos DB, customers can replicate their data across multiple locations across the globe and also across multiple locations within the same region. This makes Cosmos DB a highly available database service with almost 99.999% availability for reads and writes for multi-region modes and almost 99.99% availability for single-region modes.
In this article, we will focus more on how Azure Cosmos DB works behind the scenes and how can you get started with it using the Azure Portal. We will also explore how Cosmos DB is priced and understand the pricing model in detail.
How Azure Cosmos DB works
As already mentioned, Azure Cosmos DB is a multi-modal NoSQL database service that is geographically distributed across multiple Azure locations. This helps customers to deploy the databases across multiple locations around the globe. This is beneficial as it helps to reduce the read latency when the users use the application.
As you can see in the figure above, Azure Cosmos DB is distributed across the globe. Let’s suppose you have a web application that is hosted in India. In that case, the NoSQL database in India will be considered as the master database for writes and all the other databases can be considered as a read replicas. Whenever new data is generated, it is written to the database in India first and then it is synchronized with the other databases.
Consistency Levels
While maintaining data over multiple regions, the most common challenge is the latency as when the data is made available to the other databases. For example, when data is written to the database in India, users from India will be able to see that data sooner than users from the US. This is due to the latency in synchronization between the two regions. In order to overcome this, there are a few modes that customers can choose from and define how often or how soon they want their data to be made available in the other regions. Azure Cosmos DB offers five levels of consistency which are as follows:
- Strong
- Bounded staleness
- Session
- Consistent prefix
- Eventual
In most common NoSQL databases, there are only two levels – Strong and Eventual. Strong being the most consistent level while Eventual is the least. However, as we move from Strong to Eventual, consistency decreases but availability and throughput increase. This is a trade-off that customers need to decide based on the criticality of their applications. If you want to read in more detail about the consistency levels, the official guide from Microsoft is the easiest to understand. You can refer to it here.
Azure Cosmos DB Pricing Model
Now that we have some idea about working with the NoSQL database – Azure Cosmos DB on Azure, let us try to understand how the database is priced. In order to work with any cloud-based services, it is essential that you have a sound knowledge of how the services are charged, otherwise, you might end up paying something much higher than your expectations.
If you browse to the pricing page of Azure Cosmos DB, you can see that there are two modes in which the database services are billed.
- Database Operations – Whenever you execute or run queries against your NoSQL database, there are some resources being used. Azure terms these usages in terms of Request Units or RU. The amount of RU consumed per second is aggregated and billed
- Consumed Storage – As you start storing data in your database, it will take up some space in order to store that data. This storage is billed per the standard SSD-based storage across any Azure locations globally
Let’s learn about this in more detail.
