Easy scalability

With vertical isolation in place and each microservice rendering a specific service to the whole system, it is easy to scale. Not only is the identification easier for the scaling candidates, but the cost is less. This is because we only scale a part of the whole microservice ecosystem.

This exercise can be cost-intensive for the business; hence, prioritization of which microservice should be scaled first can now be a choice of the business team. This decision no longer has to be a choice of the development team.
