Load Balance a C## ASP.NET Core Service and Use MySql App-Layer Sharding. Shows the Concepts, Which Also Apply to MongoDB, etc.

One of the big advantages of microservices is, that they can be scaled independently. This article shows the benefits and challenges of scaling one microservice and its database.

You will create a working example application and manually implement application-layer sharding. It shows how to choose a shard key based on the use-cases and data model. This helps to apply the same principles to DBMS with integrated scaling like MongoDB, etc.

This is the first of two parts. You will implement the microservice and use a sharded DB.

In the second part, you will scale and run multiple container instances of the microservice and databases. You will use docker compose and a load balancer. Finally, you run JMeter load tests to see how the application scales when using a different number of instances.
