We were discussing the benefits of software defined stacks and we looked at examples including the one with an oncology focused software maker. The software was originally installed as a single instance multi-tenant application in the cloud. It was subsequently moved to PaaS.  The PaaS platform provided backend functions such as provisioning, deployment and security The separation of functionalities helped the oncology software maker to focus on application development and reduced schedule while the PaaS platform helped it grow.
This is true for organizations of any size. Even eBay and Paypal with its millions of users have found this strategy useful. As infrastructure and IT footprint grows, such automation improves agility.
Aside from automations, SDDC can also help with load balancing, object storage, database-as-a-service, configuration management, and application management. Together they bring improved agility and standardization.
