Creating .Net Core Microservices using Clean Architecture

June 10, 2023May 7, 2023 by Rahul

Microservices architecture has been gaining a lot of attention lately, and it’s not hard to see why. It offers many benefits, including scalability, resilience, and flexibility. .NET Core is a great platform for building microservices, and when combined with clean architecture, it can lead to even better results. In this blog post, we’ll explore the best practices for building .NET Core microservices using clean architecture, and we’ll touch on some of the tools and technologies that can help you achieve this.

Clean architecture is an approach to designing software systems that emphasizes separation of concerns and independence of implementation details. It has four main layers: the domain layer, the application layer, the infrastructure layer, and the presentation layer. Each layer has a specific role to play in the system, and they communicate with each other through well-defined interfaces.

Complete Reference of Microservices

March 14, 2023 by Rahul

Hi Guys,

I am delighted to share with you the launch of my Microservices series, “Complete Reference of Microservices” which covers all the essential details of Microservices, from learning to implementation. The series is comprised of six courses, each focusing on a specific aspect of Microservices, along with a free course on clean architecture, which provides a brief introduction to clean architecture in practice. Here is the link to the free course, “Getting started with Clean Architecture using .Net Core” which teaches the fundamentals of Clean Architecture at a high level. After mastering the basics, you can delve into the following topics from scratch. I am offering the first 100 licenses for all six courses for free on a first-come, first-served basis. Please find the links to each course below.

1. Creating .Net Core Microservices using Clean Architecture

2. Securing Microservices using Identity Server 4

3. Implementing Cross Cutting Concerns

4. Versioning Microservices

5. Building Angular Application for MicroServices

6. Deploying Microservices to Kubernetes and AKS

SQL Vs NoSql

May 28, 2023January 23, 2022 by Rahul

Hi Friends,

Its been long time since I last blogged. Hence, thought to come up with some design topics. In this case, I thought to present my take on Sql Vs NoSql. Therefore, we will be discussing the below agenda in this blog post.

Basics
Sharding
Replication
CAP Theorem
Different types of databases
Parameters to choose right database

Hotstar like Video Ingestion

October 15, 2021 by Rahul

Hi Friends,

Its been a while since my last post. Nevertheless, let’s get started again with new series of posts. In this section, we will begin new journey and see how to design system. Before designing any scalable system, what are the factors, we need to take care of? Let’s consider a scenario, where in we are designing hotstar like video ingestion system. How would we approach this part? What are the basic questions which we need take into account. Let’s look at these scenarios. Before, jumping to discussion, one point to note here that in system design problems, no solution is 100% correct and no solution is 100% wrong. These questions are open ended questions and answers can vary entirely on different scenarios presented. Hence, without wasting time, let’s get started.

Async Task vs Task

April 18, 2021 by Rahul

Hi Friends,

In this section, thought to discuss one of the topics, which I come across too often and that is whether to do async task or simply keep as task?

Whenever, async-await gets loaded in the program, it also loads state machine which means eventually, its going to have some extra code. But that makes sense as it wraps error body as well in it. If you don’t wrap it around, then you will end up having tough time identifying or reproducing the issue as this will highlight error some where in program.cs rather than actual method.

How to make Microservices communication more resilient?

January 11, 2021 by Rahul

Hi Friends,

In this section, I thought to discuss about one potential issue, which one can easily overlook and when your service really becomes busy, you will get this “Socket Exhaustion” exception. One thing to keep in mind that distributed systems are prone to error. Therefore, its always good to anticipate it before and take precautionary measures.

Year 2020 in Review

December 31, 2020 by Rahul

Hi Friends,

This year has come to end, hence thought to share yearly review. First of all, Happy New Year to all. This year has, we have witnessed many things which never happened before and we hope that, it won’t come back again. Things are looking good at the moment, economy is coming back in track. Hopefully, we will come out of this pandemic phase very soon. Hence, I borrowed this HOPE-2021 calendar pic from Kiran Mazumdar Shaw.

Kubernetes is dropping Docker, what it means?

December 24, 2020 by Rahul

Hi Friends,

In this section, thought to clear some doubts around Docker getting dropped from Kubernetes and whats the way forward now? Couple of days back Kubernetes announced this in their blog.
