Good evening,
Many organizations especially government ones have been allergic to cloud based systems.
Have a look at the below link that gives justification for cloud based systems
"The new model — called the BeyondCorp initiative — assumes that the internal network is as dangerous as the Internet. Access depends on the employee’s device and user credentials. Using authentication, authorization and encryption, the model grants employees fine-grained access to different enterprise resources"
