Isolated application environments, as opposed to a shared environment, involve deploying and managing a separate system for each customer, offering advantages such as meeting geographical and political data residency requirements and allowing customers to control upgrade schedules. While this approach is not multitenancy, a well-equipped control plane can manage customer deployments similarly. However, it requires careful consideration due to its increased operational overhead and the temptation to create bespoke customizations for individual customers, which can complicate software maintenance. Managing isolated environments involves provisioning, monitoring, and maintaining each instance from a central control plane. Independent versioning per customer is a primary benefit but necessitates strict discipline and careful management of software development lifecycles to ensure reliable upgrades and minimize possible paths. This approach, while resource-intensive, can provide significant flexibility and benefits for specific customer needs, particularly those requiring custom geographic deployment and version management options.
