A cloud application often implements a variety of operations. In some solutions it makes sense to follow the design principle of separation of concerns initially, and divide these operations into separate computational units that are hosted and deployed individually (for example, as separate App Service web apps or separate Virtual Machines). However, although this strategy can help simplify the logical design of the solution, deploying a large number of computational units as part of the same application can increase runtime hosting costs and make management of the system more complex.
