Many of today’s website is designed around giving a good user experience. This comes at a cost of high-bandwidth. Not everyone in the world will have a good internet connection, how about when you are at sea on a ship or in a developing country such as India or Pakistan.

Sample .NET Core Docker file
Here is a working example of a simple Docker file for a .NET Core 3.1 project
FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app
COPY project.csproj ./
RUN dotnet restore
COPY . ./
RUN dotnet publish -c Release -o out
FROM mcr.microsoft.com/dotnet/core/runtime:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "project.dll"]
Docker cribsheet
Build
Build an image from the Dockerfile in the current directory and tag the image
docker build -t myimage -f Dockerfile .List all images that are locally stored with the Docker Engine
docker ps -aDelete an image from the local image store
docker image rm CONTAINER_NAMEYou may want to remove all orphaned images, you can do this with dandling field
docker rmi $(docker images -f dangling=true -q)
Benefits of Containers
What Are Containers?
Containers are a form of operating system virtualization. A single container might be used to run anything from a small microservice or software process to a larger application. Inside a container are all the necessary executables, binary code, libraries, and configuration files. Compared to server or machine virtualization approaches, however, containers do not contain operating system images. This makes them more lightweight and portable, with significantly less overhead. In larger application deployments, multiple containers may be deployed as one or more container clusters. Such clusters might be managed by a container orchestrator such as Kubernetes.

API Gateway in ASP.NET Core
Working with a good technical architecture you’ll soon need to work with an API Gateway. There are many industrial solutions for large scale system giving full control and logging, such as Apigee or Software AG, but these, of course, cost a business
In this article, I’ll look at possible homegrown API’s within ASP.NET Core, which give you a lot of features without the need to pay third parties.

NET Microservices Architecture for Containerised NET Applications
I came across this guide as it is an introduction to developing microservices-based applications and managing them using containers. It discusses architectural design and implementation approaches using .NET Core and Docker containers. To make it easier to get started with containers and microservices, the guide focuses on a reference containerized and microservice-based application that you can explore. The sample application is available at the eShopOnContainers GitHub repo.

event bus interface
How do you achieve anonymity between publisher and subscriber? An easy way is to let a middleman take care of all the communication. An event bus is one such middleman.

Claim-Check Pattern
I’ve been using an Event Bus for some time now in the designs of a system, for reason of performance and scalability. There is also an issue with the message size. But it would be best if you were using the Event Bus as a messaging system, not a data transport mechanism.
There is a solution to this, and it is the claim-check pattern.
