Organizations tend to move applications to the cloud because of cost savings and the scalability factor. In doing so, an additional level of management complexity is added due to resources being shared by other tenants who may introduce risk by affecting your applications. Some of this risk may be mitigated by providing multiple instances of the application or by opting for premium tier offerings, which provide dedicated resources rather than shared resources.

For a mission-critical application to handle high demands, these factors must be considered carefully during design and must be developed from the beginning, instead of being added to the solution afterwards.

Components of a solution that are quite chatty should be kept in close proximity to each other and not distributed across networks.
