Microservices: Picking the .NET Framework for your containerized applications.

The objective of this blog post is to explain the factors that should be considered when picking a framework for a .net application that you intend to deploy in containerized fashion.

.Net Core

Generally, .Net Core is the preferred option when building applications that were intended to be deployed in containers due to the fact that .Net Core is built using modular architecture (.net core app images contains only the dependencies it requires to run). .NET Core apps are packaged using Windows Nano Server which is a far smaller compared to the OS required by the standard .NET runtime (Windows Server Core) therefore producing lighter images (end product of building containerized application).

On the image above, you will see an image built for .Net Core app that prompts "Hello World". Please take note of the size of the image (251 MB) as it would be critical to demonstrating the difference of the two frameworks.

When to pick .NET Core?

  • Building Polyglots

    Polyglots are applications built using different platforms (EG. Combination of Java and .Net processes in a SOA app). Basically, .Net Core can be used to build applications that run on both Linux and Windows.

  • Your application's architecture is Microservices

    Containers are perfect for deploying Microservices because they allow the complete isolation of services. This basically enables the use of different platforms and dependencies per service without the nasty side-effects of hosting this applications together.

  • You intend to save on hardware cost

    Images built using .NET Core have small footprints (RAM and Storage) which enables us to host different containers inside a VM or Physical machine.

  • You need fast app start up

    Since .NET Core apps ship with things it only depends on, application can quickly startup.

  • You intend to build Green-Field applications

    .NET core is the most advised framework to be used for building green-field applications (Fresh Projects). Since it is designed for the future of .NET development.

  • You intend to build high density and scalable applications.

    Since containerized applications are easy to scale using container orchestrators like Docker Swarm, Kubernetes, DC OS and Mesosphere; .NET core is the perfect framework

.Net Framework

.Net Framework is the preferred option when you intend to containerize an existing application or utilize things that deeply depend on Windows API. It is always advised to pick .NET Core over .NET framework because of the Huge image that .NET framework images produces. NOTE: Huge image size corresponds to higher cost of hosting in cloud based docker image repositories. It also means larger cost for compute power to run the containerized app.

On the image above, you will see an image built for .Net Framework app that prompts "Hello World". It is quite noticeable that this image is way larger (10.4GB) than the image built using .Net Core.

When to pick .NET Framework over .Net Core?

  • Migrate an application that is difficult to port in .Net Core

    If migrating an application from .NET Framework to .Net Core is associated with high risk over produced value, it is highly suggested to keep the existing app and host it on containers.

  • Your application depends on a binary that doesn't have a .Net Core counterpart.

    Since .NET Core is still young and hot, there are still binaries that don't have a .NET core counterpart. A perfect example of this is proprietary or internal frameworks of companies.

  • Usage of .Net technologies not available for .Net Core

    As of November 2017, ASP.net Web Forms, WCF services and Workflow related services are still not supported.

This is the pilot post for building a Raspberry Pi cluster that I intend to use for building a Nextflix replica at home for research purposes, the goal of the post is to install a Raspbian Jessie Lite on a Micro SD card that I plan to install on a Raspberry Pi 3 Model B Motherboard s. Most stores nowadays would sell Raspberry Pi 3 Model B Motherboard s that have pre-installed SD Cards and OS (Most of the time outdated). This is definitely OK and convenient but it is prone to two major problems: Guys who buy Raspberry Pi 3 Model B Motherboard s with pre-installed SD cards and OS don't understand how to install things on their own. The pre-installed OS is often outdated from what is available from the internet. Stuff you need An SD card with at least 48 MB/s transfer speed.
