Once again, remember that availability can also be defined as the proportion of available objects (services) in the total number of objects (services). 

Immediately the question arises, does the availability rate increase as the number of available objects increases and if so, how do I achieve this? To answer the question, yes.

It increases the level of availability, and with the Azure autoscaling feature, there is also a platform-based way to do it.

Scaling is a complex topic because it can occur in two ways. With vertical scaling, I do not increase the number of instances of a service but migrate the service to the next higher performance level. With horizontal scaling instead, I increase the rule-based number of instances.

In summary, while vertical scaling only influences the performance of your application, horizontal scaling can also affect the availability of the application.

Let's take a closer look at horizontal scaling. As I've already written, horizontal scaling is...
