This article will focus on creating VM, i.e., a Virtual Machine on Microsoft Azure. Microsoft Azure provides many cloud services and getting a virtual machine is one of those. One can create a virtual machine; i.e. a remote desktop machine, on the cloud and access the same with the provided credentials. Azure gives us the flexibility to choose the type of machine; i.e. client or server and the operating system and machine configuration of one’s choice. So, it gives the flexibility to create a small machine or set up a huge configuration machine based on the requirement. Each configuration and component chosen had a price that depends on how long and how much the VM is used. In this article, I’ll set a VM on Microsoft Azure step by step and this article will be more of a tutorial form.

This article will focus on setting up a custom Ethereum Blockchain on Azure. The article will be less theory and will focus more on the practical implementation of step by step setting up the Ethereum blockchain on Azure and transferring some Ethers between accounts using MetaMask. The article is for the readers who are more into development and have the background of Blockchain, Ethereum and Ether. We’ll cover theory in the next article of understanding Ethereum and Blockchain.

This article will not be very theoretical, but would be more of a tutorial to showcase the existing problems with tightly coupled applications, how to make the application loosely coupled and achieve inversion of control via dependency injection.
Inversion of control (IOC) and Dependency Injection (DI) work hand in hand and makes our application more loosely coupled and easy to expand. It is strongly recommended to follow SOLID principles when it comes to development. This article will not be very theoretical but would be more of a tutorial to showcase the existing problems with tightly coupled applications, how to make the application loosely coupled and achieve inversion of control via dependency injection, solve the problem of resolving dependency of a dependency in a three-layered/n layered project architecture using unity framework. You can get the downloadable source code at the end of the article.

In this series on learning singleton pattern, we learned lazy initialization and eager initialization with practical examples. We also learned why it is necessary to make the singleton class sealed with the sealed keyword. In this article, I’ll try to explain the differences between static and singleton class. We will also see where to use static class and where to use singleton classes.

In the previous article on learning singleton pattern, we discussed what is singleton design pattern, when is it needed and what problems it solves. We also discussed how to create a basic singleton class step by step and how to enhance that class to be thread-safe with the help of locking and performance effective with the help of double check locking. In this article, we’ll discuss Lazy initialization, the lazy keyword, why to make singleton class a sealed class, and what are the differences between singleton and static class. Before we start, I strongly recommend you go through my last article.

I always wanted to write on Singleton design pattern in C#. Though there already are many posts available on Singleton design pattern, I’ll try to cover this topic in the most simplistic and easy to understand way.
